DISCUSSION:
On February 14, 2023, the City Council adopted Ordinance No. 2023-2, the most recent
update to the City's ADU regulations. The ordinance was submitted to the California
Department of Housing and Community Development (HCD) for review, as required by
State law.
In 2024, the State Legislature enacted several housing bills (SB 477, AB 2533, and SB
1211) amending Government Code Sections 66310 through 66342 to impose new
requirements on ADUs and JADUs. These changes apply to charter cities and are
intended to remove barriers, reduce costs, streamline approvals, and expand ADU and
JADU development to address the housing shortage. Additional details regarding these
housing bills are provided in the Changes to State ADU Laws subsection of this report.
Following adoption of the City's revised Housing Element on September 24, 2024, HCD
reviewed the City's ADU ordinance as part of the Housing Element recertification process
and, on October 1, 2024, issued a letter (HCD Letter) stating that it does not comply with
State ADU Law (Attachment C). The HCD Letter outlined areas requiring revision and
directed the City to (1) update the ordinance to address the comments or (2) justify how
the existing ordinance is consistent with State law. The comments received by HCD were
intended to guide the City in addressing the changes to State law. The HCD Letter also
stated that failure to act may result in notification to the California Attorney General.
On October 25, 2024, the Community Development Department responded to HCD,
affirming the City's intent to revise the ordinance and ensure compliance with State law.
Planning Commission Review
On July 17, 2025, the Planning Commission considered the proposed amendments to
Titles 20 and 21 of the Newport Beach Municipal Code (NBMC). Prior to the public
hearing, one public comment letter was received from the California Housing Defense
Fund. The letter provided two separate comments on the proposed amendments related
to Government Code Section 66323. The first comment was related to the allowance of
up to eight detached ADUs on parcels with existing multifamily lots, and the second
comment related to not imposing historic standards on ADUs. Staff addressed the
comment letter during the public hearing, noting that the amendment already includes a
reference to Government Code Section 66323, which permits up to eight detached ADUs
on existing multifamily lots. Additionally, staff revised the draft code language to address
the second comment regarding historic resources.
At the conclusion of the public hearing, the Planning Commission adopted Resolution No.
PC2025-014 by a unanimous vote (4 ayes, 0 nays, 3 absent) recommending approval of
the Zoning Code Amendment to the City Council and recommending the City Council
authorize the submittal of the Local Coastal Program Amendment to the California
Coastal Commission. A copy of the July 17, 2025, Planning Commission staff report is
included as Attachment D and the meeting minutes are included as Attachment E.

Changes to State ADU Laws
SB 477, effective March 25, 2024, reorganized the numbering of Government Code
sections related to ADUs and JADUs. AB 2533, effective January 1, 2025, introduced
updates addressing unpermitted ADUs, which the City has incorporated into its SAFE
ADU Program to help homeowners legalize units built before January 1, 2020. SB 1211,
also effective January 1, 2025, revised regulations for replacement parking and
introduced streamlined "66323 Units" (described below) for multifamily properties, further
expanding ADU development opportunities.
SB 1211 created a new category of ADUs called "66323 Units" under Government Code
Section 66323. These units must be approved ministerially and are exempt from most
local development standards (i.e. height, setbacks, etc.), though they must still meet
building code and health and safety rules. There are four types of 66323 Units:
1. Single Unit Internal ADUs and JADUs
• One ADU per lot is permitted within converted space of a proposed or
existing single -unit dwelling or accessory structure.
• No additional setbacks are required beyond that of the existing or proposed
structure and applicable building and safety minimum requirements.
• ADUs converted from accessory structures are eligible for a 150 square -
foot expansion to accommodate ingress and egress.
• One JADU per lot is permitted within the proposed or existing space of a
single -unit dwelling or accessory structure.
2. Single -Unit Detached ADUs
• One detached new construction ADU is permitted on lots with an existing or
proposed single -unit dwelling.
• 4-foot side and rear yard setbacks are allowed.
• The maximum unit size is 800 square feet.
• Height limitation of 16 or 18 feet depending on conditions specified in
Government Code Section 66321, subdivision (b)(4).
3. Multi -unit Converted ADUs
Conversion ADUs may be created within the portions of existing multi -unit
structures that are not used as livable space.
At least one ADU is within an existing multi -unit dwelling and up to 25% of
the existing multi -unit dwelling units.
4. Multi -unit Detached ADUs
Two detached ADUs are allowed on a lot with a proposed multi -unit
dwelling, or up to eight detached ADUs are allowed on a lot with an existing
multi -unit dwelling, not to exceed the number of existing units on the lot.

• 4-foot rear and side yard setbacks are allowed.
• Height limits of 16, or 18 feet depending on conditions specified in
Government Code Section 66321, subdivision (b)(4).
Proposed Amendments
The proposed ordinance (Attachment A) and proposed resolution (Attachment B) address
all comments identified in the HCD Letter and associate changes to State ADU Law. Table
1 (HCD Letter Summary) of Attachment F summarizes the comments provided by HCD
and identifies how the City intends to address those comments. As requested by HCD,
the ordinance and resolution include an exhibit with the findings addressing why certain
changes requested by HCD are not necessary to comply with State ADU law. All the other
suggested changes have been made in the proposed ordinance.
Specifically, amendments to Sections 20.48.200 (Accessory Dwelling Units) and
21.48.200 (Accessory Dwelling Units) of the NBMC are proposed. Although the titles of
said sections reference ADUs, these sections also govern JADUs. Redlines of Sections
20.48.200 and 21.48.200 of the NBMC addressing the HCD Letter are included as
Attachments G and H, respectively. The Planning Division has also created a matrix to
assist the public and staff in understanding ADU regulations. The ADU Ordinance
Summary Matrix (Attachment 1) provides an outline of the current ADU regulations and
the Proposed ADU Ordinance Summary Matrix provides an outline of the proposed ADU
regulations (Attachment J).
General Plan Consistency
State law considers ADUs to be accessory residential uses that do not increase a
property's allowed density and are consistent with the General Plan and Zoning. As a
result, no changes to the General Plan are needed. Adopting an ordinance that follows
Government Code Sections 66310 through 66342 supports the City's commitment to
expanding ADU development, as outlined in Policy Action 1 H of the 2021-2029 Housing
Element.
Local Coastal Plan
The Local Coastal Plan (LCP) currently regulates ADUs in a way that doesn't align with
State law. If the City Council adopts the Zoning Code amendment, staff will submit related
changes to the LCP for review and approval by the California Coastal Commission (CCC).
Updating the LCP ordinance will help the City carry out Local Coastal Program Policy 2.7-
5, which supports State ADU laws to increase affordable housing in coastal areas while
preserving neighborhood character.

Government Code Section 66326 requires the City to submit the ordinance to HCD within
60 days of adoption. Should the City Council approve the proposed ordinance to amend
Title 20, staff will forward the ordinance to HCD for review. If HCD finds the ordinance
does not comply with the new ADU laws, HCD will notify the City. Should this occur, the
City would have 30 days to either amend the ordinance or adopt additional findings that
explain the reason the ordinance complies with the statute. Since the amendment to Title
21 requires CCC approval, the ordinance amending Title 21 will be submitted to HCD
after the CCC LCP amendment process is complete.
FISCAL IMPACT:
There is no fiscal impact related to this item.
ENVIRONMENTAL REVIEW:
Staff recommends the City Council find this project exempt from environmental review
under the California Environmental Quality Act (CEQA) pursuant to Public Resources
Code Section 21080.17 and CEQA Guidelines Section 15282(h), which states that the
adoption of an ordinance regarding second units to implement the provisions of Sections
66310 through 66342 of the Government Code are exempt from the requirements of
CEQA. Similarly, the ministerial approval of ADUs would not be a project for CEQA
purposes, and environmental review would not be required prior to approving individual
applications. In addition, pursuant to CEQA Guidelines Section 15265(a)(1), local
governments are exempt from the requirements of CEQA in connection with the adoption
of a Local Coastal Program.
NOTICING:
Pursuant to Section 13515 of the California Code of Regulations, a review draft of the
LCP amendment was made available, and a Notice of Availability was distributed on July
15, 2025, to all persons and agencies on the Notice of Availability mailing list.
Notice of this hearing was published in the Daily Pilot as an eighth -page advertisement,
consistent with the provisions of the NBMC. The item also appears on the agenda for this
meeting, which was posted at City Hall and on the City website.

A. Purpose. The purpose of this section is to establish the procedures for the creation
of accessory dwelling units and junior accessory dwelling units, as defined in Part 7
(Definitions) of this title and in California Government Code Sections 66310 through
66342, in areas designated for residential use, including as part of a planned community
development plan or specific plan, and to provide development standards to ensure the
orderly development of these units in appropriate areas of the City.
B. Effect of Conforming. An accessory dwelling unit or junior accessory dwelling unit
that conforms to the requirements in this section shall not be:
1. Deemed to be inconsistent with the General Plan and zoning district designation

and/or unpermitted structure(s) that do/does not present a threat to public health and
safety and is/are not affected by the construction of the accessory dwelling unit or
junior accessory dwelling unit. This does not prevent the City from enforcing
compliance with applicable building standards in accordance with California Health
and Safety Code Section 17980.12.

2. The dwelling conforms to the development standards and requirements for
accessory dwelling units and/or junior accessory dwelling units as provided in this
section and California Government Code Section 66323; and
3. The building permit shall be considered and approved ministerially, without
discretionary review or a hearing, within sixty (60) days from the date that the City

required to be replaced. Outside the coastal zone, when a garage is demolished
34-17
in conjunction with the construction of a junior accessory dwelling unit at the same

4. Septic Systems. If the principal dwelling unit is currently connected to an on -site
wastewater treatment system and is unable to connect to a sewer system, accessory
dwelling units and junior accessory dwelling units may connect to the on -site
wastewater treatment system. However, the owner must include with the application
a percolation test completed within the last five years or, if the percolation test has
been recertified, within the last ten (10) years.
H. Additional Requirements for All Accessory Dwelling Units and Junior Accessory
Dwelling Units.
1. No Separate Conveyance. Except as authorized in California Government Code
66341, an accessory dwelling unit or junior accessory dwelling unit may be rented,
but no accessory dwelling unit or junior accessory dwelling unit may be sold or

a single -unit dwelling) or from the lot and all of the dwellings (in the case of a multi-
unit dwelling).
2. Short -Term Lodging. The accessory dwelling unit and/or junior accessory dwelling
unit shall not be rented for periods of thirty (30) days or less.
3. Owner -Occupancy for Junior Accessory Dwelling Units. A natural person with
legal or equitable title to the lot must reside in either the principal single -unit dwelling
unit or the junior accessory dwelling unit as the person's legal domicile and permanent
residence. However, this owner -occupancy requirement shall not apply to any junior

34-19
EXHIBIT "B"
FACTS IN SUPPORT OF CODE AMENDMENT (PA2025-0093)
An amendment to Title 20 (Planning and Zoning) of the NBMC is a legislative act. Neither
Chapter 20.66 (Planning and Zoning, Amendments) of Title 20 (Planning and Zoning) of
the NBMC, or Article 2 (Adoption of Regulations) of Chapter 4 (Zoning Regulations) of
Division 1 (Planning and Zoning) of Title 7 (Planning and Land Use) of the California
Government Code set forth any required findings for either approval or denial of such
amendments.
Notwithstanding the foregoing, the Zoning Code Amendment is consistent with the City
Council' s initiation and allows for orderly residential development while protecting property
rights, as identified below.
1. ADUs and JADUs provide housing for family members, students, the elderly, in -home
health care providers, the disabled, and others, at below market prices within existing
neighborhoods. In addition, homeowners who construct ADUs and JADUs benefit from
added income and increased sense of security.
2. Allowing ADUs and JADUs in conjunction with existing or proposed residential
development provides additional rental housing stock, some of which will satisfy the
City's 6th Cycle Regional Housing Needs Assessment (RNHA).
3. Adopting an ordinance consistent with Government Code Sections 66310 through
66342 ensures and reinforces the commitment that the City has made to promote and
incentivize ADU growth via the established Policy Action 1 H: Accessory Dwelling Unit
Construction of the City's 6th Cycle Housing Element.
4. Adopting an ordinance to address State ADU Law revisions is consistent with Council
Policy K-4 (Reducing the Barriers to the Creation of Housing) which encourages the
development of accessory dwelling units as an important strategy to accommodate
future growth and as an integral strategy to help meet the City's Regional Housing
Needs Allocation (RHNA).
5. ADUs and JADUs offer lower cost housing to meet the needs of existing and future
residents within existing neighborhoods inside and outside the coastal zone, while
respecting architectural character.
6. Adopting an ordinance consistent with Government Code Sections 66310 through
66342 ensures that the character of the City is preserved to the maximum extent
possible and that the City's regulation regarding ADUs and JADUs continues to
promote the health, safety, and welfare of the community.
7. The proposed amendments are consistent with and implement California Government
Code Sections 66310 through 66342. The proposed changes to the NBMC are solely
intended to address updated requirements under State ADU Law and the HCD Letter.
No additional changes are proposed as part of this amendment.
34-20
8. The HCD Letter requests that NBMC Section 20.38.200 (D) (3) and (4)(a)(iii) be
amended to address the definition of a "lot". HCD cites the 2022 California Building Code
(CBC), which defines "lot" as "A portion or parcel of land considered as a unit". However,
Government Code Sections 66310 through 66342 do not include a definition of a "lot"
and do not cite the CBC for the definition of a "lot". The existing language of NBMC
Section 20.38.200 (D)(3) and (4)(a)(iii) reads, "For purposes of this section, a multi -unit
development approved and built as a single complex shall be considered one lot,
regardless of the number of parcels." This language is consistent with NBMC Section
20.70.020 (Definitions of Specialized Terms and Phrases) which defines a "lot" as,
"...the basic unit of land development. A designated area of land established by plat,
subdivision, lot line adjustment, or as otherwise permitted by law, to be used,
developed, or built upon as a unit. Typically, a lot is indicated upon a final map, parcel
map, lot line adjustment map, certificate of compliance, or record of merger filed in the
Office of the County Recorder...". Furthermore, NBMC Section 20.70.020 (Definitions
of Specialized Terms and Phrases) defines "Site" as, "...a lot or adjoining lots under
single ownership or single control, considered as a [Numerical] unit for the purposes
of development or other use." These codified definitions adequately define "lot" for the
purpose of regulating ADUs and JADUs, therefore, no changes are necessary to
address this comment from HCD.
9. The HCD Letter asserts that the City cannot impose standards of a local ordinance,
regulation, or policy not contained within the City's ADU ordinance from being the basis
of delay or denial of an ADU or JADU, with the exception of the CBC. However, pursuant
to Government Code Section 66314 (b)(1), a local jurisdiction is allowed to impose
objective standards on ADUs and JADUs, with the exception of ADUs and JADUs that
are specifically protected under Section 66323 of the Government Code. Therefore, the
proposed amendment includes references to Government Code 66323 to ensure that
Government Code 66323 supersedes the development standards of the NBMC where
applicable.
10. The HCD Letter requests NBMC Section 20.38.200 (F)(2)(b) related to setbacks be
amended to include reference to JADUs in the language to process building permits and
demolition permits concurrently for ADUs that are proposed to replace a detached
garage. However, Government Code sections 66310 through 66342 do not explicitly
allow JADUs to be created from detached structures, including garages. Therefore,
adding JADUs into NBMC Section 20.38.200 (F)(3) would create privileges for JADU
development that are not found in Government Code Sections 66310 through 66342.
Therefore, the existing language is consistent with the provisions of Government Code
Section 66333(d). No changes are necessary to address this comment from HCD.
11. The HCD Letter requests that NBMC Section 20.38.200 (F)(3)(b) be amended to clarify
that the height limit for ADUs and JADUs attached to a primary dwelling shall not be less
than 25 feet or the height limitation in the local zoning ordinance that applies to the
primary dwelling, whichever is lower. The existing ADU ordinance language outlines that
attached ADUs and JADUs are limited to the base height limit for the primary dwelling.
The City's various residential zoning districts have base height limits that exceed the 25-
foot height limit allowed by the State, therefore, the City's existing ADU Ordinance is
more permissive than State ADU Law. Imposing the requested amendment would
impose a height limit that is lower than currently permitted by the underlying zoning
34-21
districts. Therefore, The City's existing ordinance is more permissive than State ADU
Law and no amendments are necessary to address this comment from HCD.
12. The HCD letter requests that NBMC Section 20.48.200 (H)(3) be amended to remove
owner occupancy requirements for ADUs. This revision is not necessary given the
existing ADU ordinance does not require owner occupancy of ADUs and specifies that
owner occupancy is only required for JADUs. JADU owner occupancy is authorized by
Government Code Section 66333(b). Therefore, no changes are necessary to address
this comment from HCD.
13. The recitals provided in this resolution are true and correct and are incorporated into
the operative part of this resolution.

EXHIBIT "A"
LOCAL COASTAL PROGRAM AMENDMENT NO. PA2025-0093
Section 21.48.200 (Accessory Dwelling Units) of Chapter 21.48 (Standards for
Specific Land Uses) of Title 21 (Local Coastal Program Implementation Plan) of the
NBMC is amended as follows:
21.48.200 Accessory Dwelling Units.
A. Purpose. The purpose of this section is to establish the procedures for the creation
of accessory dwelling units and junior accessory dwelling units, as defined in Part 7
(Definitions) of this title and in California Government Code Sections 66310 through
66342, or any successor statute, in areas designated for residential use, including as part
of a planned community development plan or specific plan, and to provide development
standards to ensure the orderly development of these units in appropriate areas of the
City.
B. Effect of Conforming. An accessory dwelling unit or junior accessory dwelling unit
that conforms to the requirements in this section shall not be:
1. Deemed to be inconsistent with the Coastal Land Use Plan and coastal zoning
district designation for the lot on which the accessory dwelling unit or junior accessory
dwelling unit is located;
2. Deemed to exceed the allowable density for the lot on which the accessory
dwelling unit or junior accessory dwelling unit is located;
3. Considered in the application of any ordinance, policy, or program to limit
residential growth; or
4. Required to correct nonconforming zoning condition(s), building code violation(s),
and/or unpermitted structure(s) that do/does not present a threat to public health and
safety and is/are not affected by the construction of the accessory dwelling unit or
junior accessory dwelling unit; and do/does not raise inconsistency with the coastal
resource protection policies of subsection (C)(3) of this section. This does not prevent
the City from enforcing compliance with applicable building standards in accordance
with California Health and Safety Code Section 17980.12.
C. Review Authority. Accessory dwelling units and junior accessory dwelling units shall
be approved in any residential or mixed -use zoning district, subject to a building permit
and the following conditions:
There is an existing or proposed dwelling unit on the lot;
2. The dwelling conforms to the development standards and requirements for
accessory dwelling units and/or junior accessory dwelling units as provided in this
section and California Government Code Section 66323;
34-28
3. The dwelling conforms to the coastal resource protection development regulations
of the Implementation Plan and Coastal Land Use Plan provisions, including
Implementation Plan Section 21.28.040 (Bluff (B) Overlay District), 21.28.050
(Canyon (C) Overlay District), 21.30.100 (Scenic and Visual Quality Protection), or
Chapter 21.30B (Habitat Protection); and
4. The building permit shall be considered and approved ministerially, without
discretionary review or a hearing, within sixty (60) days from the date that the City
determines an application to be complete, unless either:
a. The applicant requests a delay, in which case the sixty (60) day time period
is tolled for the period of the requested delay, or
b. In the case of an application for an accessory dwelling unit and/or junior
accessory dwelling unit submitted with an application to create a new single -unit
dwelling on the lot, the City may delay acting on the accessory dwelling unit and/or
junior accessory dwelling application until the City renders a decision on the new
single -unit dwelling application.
D. Coastal Development Permits.
1. Application. The applicant shall obtain a coastal development permit, pursuant to
Chapter 21.52 (Coastal Development Review Procedures), unless otherwise exempt
or excluded from the coastal development permit process pursuant to Section
21.52.035 (Projects Exempt From Coastal Development Permit Requirements) or
21.52.045 (Categorical Exclusions).
2. Hearing Exemption. All of the provisions of Chapter 21.52 (Coastal Development
Review Procedures) regarding the review and approval of coastal development
permits in relation to accessory dwelling units are applicable, except that a public
hearing as required by Chapter 21.62 (Public Hearings) shall not be required. Public
notice shall be provided as required in Section 21.62.020, except the requirements of
Section 21.62.020(A) shall be replaced with a statement that no local public hearing
will be held and that written comments on the proposed development may be
submitted. Written comments received shall be reviewed by the review authority.
3. Appeal Exemption. Notwithstanding the local appeal provisions of Chapter 21.64
(Appeals and Calls for Review), coastal development permits for accessory dwelling
units that are defined as "appealable development" pursuant to Section 21.64.035(A)
may be directly appealed to the Coastal Commission in accordance with the
provisions of Section 21.64.035 without a discretionary hearing by the Planning
Commission or City Council.
E. Maximum Number of Accessory Dwelling Units Allowed. Unless precluded by
Government Code Section 66323 the following is the maximum number of accessory
dwelling units allowed on any residential lot. For purposes of this section, "multi -unit
dwelling" means a development containing two or more dwelling units on one lot.
34-29
1. Internal to a Single -Unit or Multi -Unit Dwelling Category. Only one accessory
dwelling unit may be permitted on a lot with a proposed or existing single -unit or multi-
unit dwelling, subject to the following:
a. The accessory dwelling unit is proposed:
i. Within the space of a proposed single -unit or multi -unit dwelling; or
ii. Within the existing space of an existing single -unit or multi -unit dwelling; or
iii. Within the existing space of an existing accessory structure, plus an
addition beyond the physical dimensions of the existing structure of up to one
hundred fifty (150) square feet if the expansion is limited to accommodating
ingress and egress.
b. The accessory dwelling unit shall have independent exterior access from the
single -unit dwelling.
c. Side and rear setbacks comply with Titles 9 (Fire Code) and 15 (Buildings
and Construction).
2. Attached on Lot With Single -Unit or Multi -Unit Dwelling Category. Only one
attached, new construction accessory dwelling unit may be permitted on a lot with a
proposed or existing single -unit or multi -unit dwelling.
3. Detached on Lot With Single -Unit or Multi -Unit Dwelling Category. Only one
detached new construction accessory dwelling unit may be permitted on a lot with a
proposed or existing single -unit dwelling. Up to two detached new construction
accessory dwelling units may be constructed on a lot that has an existing or proposed
multi -unit dwelling. For purposes of this section, a multi -unit development approved
and built as a single complex shall be considered one lot, regardless of the number
of parcels.
4. Conversion of Multi -Unit Dwelling Category. Multiple accessory dwelling units
may be permitted on lots with existing multi -unit dwellings subject to the following:
a. The number of accessory dwelling units shall not exceed twenty-five (25)
percent of the existing multi -unit dwellings on the lot. For the purpose of
calculating the number of allowable accessory dwelling units, the following shall
apply:
i. Previously approved accessory dwelling units shall not count towards the
number of existing multi -unit dwellings;
ii. Fractions shall be rounded down to the next lower number of dwelling units,
except that at least one accessory dwelling unit shall be allowed; and
iii. For the purposes of this section, multi -unit developments approved and
built as a single complex shall be considered one lot, regardless of the number
of parcels.
34-30

single -unit or multi -unit dwelling.
34-33
7. Passageway. No passageway shall be required in conjunction with the
construction of an accessory dwelling unit and/or junior accessory dwelling unit. For
the purposes of this section, "passageway" means a pathway that is unobstructed
clear to the sky and extends from the street to one entrance of the accessory dwelling
unit.
8. Parking. Parking shall comply with requirements of Chapter 21.40 (Off -Street
Parking) except as modified below:
a. No additional parking shall be required for junior accessory dwelling units.
b. A maximum of one parking space shall be required for each accessory
dwelling unit.
c. When additional parking is required, the parking may be provided as tandem

parking shall be provided. Replacement parking may be located in any
configuration on the same lot as the accessory dwelling unit, including, but not
limited to, as covered spaces, uncovered spaces, or tandem spaces, or by the
use of mechanical automobile parking lifts. Accessory dwelling units shall not
displace required uncovered parking spaces.
34-34
9. Waterfront Development and Flood Hazard Areas.
a. The minimum top of slab elevation for new interior living areas, including
areas converted from nonliving areas, shall comply with the flood hazard and sea
level rise protection standards of Section 21.30.015(D).
b. Any development in shoreline hazardous areas shall comply with Section
21.30.015(E).
10. Historic Resources. Any accessory dwelling unit or junior accessory dwelling
unit that is listed on the California Register of Historic Resources shall meet all
Secretary of the Interior standards, as applicable.
H. Utility Connection.
1. Connection Required. All accessory dwelling units and junior accessory dwelling
units shall connect to public utilities (or their equivalent), including water, electric, and
sewer services.
2. Except as provided in subsection (H)(3) of this section, the City may require the
installation of a new or separate utility connection between the accessory dwelling
unit, junior accessory dwelling unit and the utilities.
3. Conversion. No separate connection between the accessory dwelling unit and
the utility shall be required for units created within a single -unit or multi -unit
dwelling(s), unless the accessory dwelling unit is being constructed in connection with
a new single -unit dwelling or multi -unit dwellings.
4. Septic Systems. If the principal dwelling unit is currently connected to an on -site
wastewater treatment system and is unable to connect to a sewer system, accessory
dwelling units and junior accessory dwelling units may connect to the on -site
wastewater treatment system. However, the owner must include with the application
a percolation test completed within the last five years or, if the percolation test has
been recertified, within the last ten (10) years.
I. Additional Requirements for All Accessory Dwelling Units and Junior Accessory
Dwelling Units.
1. No Separate Conveyance. Except as authorized in California Government Code
66341, an accessory dwelling unit or junior accessory dwelling unit may be rented,
but no accessory dwelling unit or junior accessory dwelling unit may be sold or
otherwise conveyed separately from the lot and the principal dwelling (in the case of
a single -unit dwelling) or from the lot and all of the dwellings (in the case of a multi-
unit dwelling).
2. Short -Term Lodging. The accessory dwelling unit and/or junior accessory dwelling
unit shall not be rented for periods of thirty (30) days or less.
3. Owner -Occupancy for Junior Accessory Dwelling Units. A natural person with
legal or equitable title to the lot must reside in either the principal single -unit dwelling
34-35
unit or the junior accessory dwelling unit as the person's legal domicile and permanent
residence. However, this owner -occupancy requirement shall not apply to any junior
accessory dwelling unit owned by a governmental agency, land trust, or housing
organization.
J. Deed Restriction and Recordation Required.
1. Prior to the issuance of a building and/or grading permit for a junior accessory
dwelling unit, the property owner shall record a deed restriction with the County
Recorder's Office, the form and content of which is satisfactory to the City Attorney.
The deed restriction document shall notify future owners of the owner -occupancy
requirements, prohibition on the separate conveyance, the approved size and
attributes of the unit, and restrictions on short-term rentals. This deed restriction shall
remain in effect so long as the junior accessory dwelling unit exists on the lot.
2. For properties in flood hazard areas as identified by the Federal Emergency
Management Agency in the "Flood Insurance Study" for Orange County, California
and Incorporated Area with accompanying FEMA Flood Insurance Rate Maps, deed
restriction shall also include notice to future owners that the unit is located within an
area that may be subject to flooding or future flooding.
3. For properties located in low lying shoreline areas that may be subject to future
sea level rise, the property owner shall also record a waiver of future protection in
compliance with Section 21.30.015(E)(5).
34-36
EXHIBIT "B"
FACTS IN SUPPORT OF LOCAL COASTAL PROGRAM AMENDMENT (PA2025-0093)
An amendment to Title 21 (Local Coastal Program Implementation Plan) of the NBMC is a
legislative act. Neither Chapter 20.66 (Planning and Zoning, Amendments) of Title 20
(Planning and Zoning) of the NBMC, or Article 2 (Adoption of Regulations) of Chapter 4
(Zoning Regulations) of Division 1 (Planning and Zoning) of Title 7 (Planning and Land Use)
of the California Government Code set forth any required findings for either approval or
denial of such amendments.
Notwithstanding the foregoing, the Zoning Code Amendment is consistent with the City
Council' s initiation and allows for orderly residential development while protecting property
rights, as identified below.
1. ADUs and JADUs provide housing for family members, students, the elderly, in -home
health care providers, the disabled, and others, at below market prices within existing
neighborhoods. In addition, homeowners who construct ADUs and JADUs benefit from
added income and increased sense of security.
2. Allowing ADUs and JADUs in conjunction with existing or proposed residential
development provides additional rental housing stock, some of which will satisfy the
City's 6th Cycle Regional Housing Needs Assessment (RNHA).
3. Adopting an ordinance consistent with Government Code Sections 66310 through
66342 ensures and reinforces the commitment that the City has made to promote and
incentivize ADU growth via the established Policy Action 1 H: Accessory Dwelling Unit
Construction of the City's 6tn Cycle Housing Element.
4. Adopting an ordinance to address State ADU Law revisions is consistent with Council
Policy K-4 (Reducing the Barriers to the Creation of Housing) which encourages the
development of accessory dwelling units as an important strategy to accommodate
future growth and as an integral strategy to help meet the City's Regional Housing
Needs Allocation (RHNA).
5. By adopting an ordinance amending the Local Coastal Program, the City will continue
to implement Coastal Land Use Plan Policy 2.7-5 of the Local Coastal Program, which
encourages consistency with State ADU Law for the purpose of increasing the supply
of lower -cost housing in the coastal zone that meets the needs of existing and future
residents, while respecting the architectural character of the existing neighborhoods
and remaining consistent with the LCP.
6. ADUs and JADUs offer lower cost housing to meet the needs of existing and future
residents within existing neighborhoods inside and outside the coastal zone, while
respecting architectural character.
34-37
7. Adopting an ordinance consistent with Government Code Sections 66310 through
66342 ensures that the character of the City is preserved to the maximum extent
possible and that the City's regulation regarding ADUs and JADUs continues to
promote the health, safety, and welfare of the community.
8. The proposed amendments are consistent with and implement California Government
Code Sections 66310 through 66342. The proposed changes to the NBMC are solely
intended to address updated requirements under State ADU Law and the HCD Letter.
No additional changes are proposed as part of this amendment.
9. The HCD Letter requests that NBMC Section 20.38.200 (D) (3) and (4)(a)(iii) be
amended to address the definition of a "lot". HCD cites the 2022 California Building Code
(CBC), which defines "lot" as "A portion or parcel of land considered as a unit." However,
Government Code Sections 66310 through 66342 do not include a definition of a "lot"
and do not cite the CBC for the definition of a "lot". The existing language of NBMC
Section 20.38.200 (D)(3) and (4)(a)(iii) reads, "For purposes of this section, a multi -unit
development approved and built as a single complex shall be considered one lot,
regardless of the number of parcels." This language is consistent with NBMC Section
20.70.020 (Definitions of Specialized Terms and Phrases) which defines a "lot" as,
"...the basic unit of land development. A designated area of land established by plat,
subdivision, lot line adjustment, or as otherwise permitted by law, to be used,
developed, or built upon as a unit. Typically, a lot is indicated upon a final map, parcel
map, lot line adjustment map, certificate of compliance, or record of merger filed in the
Office of the County Recorder..." Furthermore, NBMC Section 20.70.020 (Definitions
of Specialized Terms and Phrases) defines "Site" as, "...a lot or adjoining lots under
single ownership or single control, considered as a [Numerical] unit for the purposes
of development or other use." These codified definitions adequately define "lot" for the
purpose of regulating ADUs and JADUs, therefore, no changes are necessary to
address this comment from HCD.
10. The HCD Letter asserts that the City cannot impose standards of a local ordinance,
regulation, or policy not contained within the City's ADU ordinance from being the basis
of delay or denial of an ADU or JADU, with the exception of the CBC. However, pursuant
to Government Code Section 66314 (b)(1), a local jurisdiction is allowed to impose
objective standards on ADUs and JADUs, with the exception of ADUs and JADUs that
are specifically protected under Section 66323 of the Government Code. Therefore, the
proposed amendment includes references to Government Code 66323 to ensure that
Government Code 66323 supersedes the development standards of the NBMC where
applicable.
11. The HCD Letter requests NBMC Section 20.38.200 (F)(2)(b) related to setbacks be
amended to include reference to JADUs in the language to process building permits and
demolition permits concurrently for ADUs that are proposed to replace a detached
garage. However, Government Code sections 66310 through 66342 do not explicitly
allow JADUs to be created from detached structures, including garages. Therefore,
adding JADUs into NBMC Section 20.38.200 (F)(3) would create privileges for JADU
development that are not found in Government Code Sections 66310 through 66342.
34-38
Therefore, the existing language is consistent with the provisions of Government Code
Section 66333(d). No changes are necessary to address this comment from HCD.
12. The HCD Letter requests that NBMC Section 20.38.200 (1=)(3)(b) be amended to clarify
that the height limit for ADUs and JADUs attached to a primary dwelling shall not be less
than 25 feet or the height limitation in the local zoning ordinance that applies to the
primary dwelling, whichever is lower. The existing ADU ordinance language outlines that
attached ADUs and JADUs are limited to the base height limit for the primary dwelling.
The City's various residential zoning districts have base height limits that exceed the 25-
foot height limit allowed by the State, therefore, the City's existing ADU Ordinance is
more permissive than State ADU Law. Imposing the requested amendment would
impose a height limit that is lower than currently permitted by the underlying zoning
districts. Therefore, The City's existing ordinance is more permissive than State ADU
Law and no amendments are necessary to address this comment from HCD.
13. The HCD letter requests that NBMC Section 20.48.200 (H)(3) be amended to remove
owner occupancy requirements for ADUs. This revision is not necessary given the
existing ADU ordinance does not require owner occupancy of ADUs and specifies that
owner occupancy is only required for JADUs. JADU owner occupancy is authorized by
Government Code Section 66333(b). Therefore, no changes are necessary to address
this comment from HCD.
14. The recitals provided in this resolution are true and correct and are incorporated into
the operative part of this resolution.

Jaime Murillo, Community Development Deputy Director
Department of Community Development
City of Newport Beach
100 Civic Center Drive,
Newport Beach, CA 92660
Dear Jaime Murillo:
RE: Review of Newport Beach's Accessory Dwelling Unit (ADU) Ordinance under
State ADU Law (Gov. Code, §§ 66310 - 66342)
Please Note: As of March 25, 2024, with the Chaptering of Senate Bill (SB) 477 (Chapter 7,
Statutes of 2024), the sections of Government Code relevant to State ADU and junior
accessory dwelling unit (JADU) Law have been re -numbered (Enclosure 1).
Thank you for submitting the City of Newport Beach's accessory dwelling unit (ADU)
Ordinance No. 2023-2 (Ordinance), adopted February 14, 2023, to the California
Department of Housing and Community Development (HCD). The Ordinance was
received on February 18, 2023. HCD has reviewed the Ordinance and submits these
written findings pursuant to Government Code section 66326, subdivision (a). HCD
finds that the Ordinance fails to comply with State ADU and JADU Laws in the manner
noted below. Pursuant to Government Code section 66326, subdivision (b)(1), the City
has up to 30 days to respond to these findings. Accordingly, the City must provide a
written response to these findings no later than October 31, 2024.
The Ordinance addresses many statutory requirements; however, HCD finds that the
Ordinance does not comply with State ADU Law as follows:
1. Section 20.48.200 B.4. — Legally Established Non -conforming Zoning Conditions
— The Ordinance does not require ADUs and JADUs to "...correct legally
established nonconforming zoning condition(s), building code violation(s), and/or
unpermitted structure(s) that do/does not present a threat to public health and
safety and is/are not affected by the construction of the accessory dwelling unit
or junior accessory dwelling unit." However, Government Code section 66323,
subdivision (b) specifically provides that a local agency shall not require the
correction of nonconforming zoning conditions. Additionally, section 66322(b)
prohibits the denial of a permit due to the correction of nonconforming zoning
conditions, building code violations, or unpermitted structures that do not
34-41
present a threat to public health and safety and are not affected by the
construction of the ADU. Neither section includes "legally established'.
Unpermitted structures are unlikely legally established. The City's ordinance
therefore likely restricts units whose protection is specifically provided for by
statute. Therefore, the City must remove the phrase "legally established" from
the Ordinance.
2. Section 20.48.200 C.2. — Conditions on Development— The Ordinance requires
ADUs and JADUs conform to development standards and requirements "as
provided in this section." Government Code section 66323, subdivision (a),
states, "Notwithstanding Sections 66314 to 66322, inclusive, a local agency
shall ministerially approve an application for a building permit within a residential
or mixed -use zone to create any of the following..." Section 66323 precludes
zoning development standards and requirements for ADUs and JADUs.
Therefore, the City must note the exception for units described in subdivision (a)
in its ordinance.
3. Section 20.48.200 D.1. — Unit Allowance — The Ordinance states, "Only one (1)
of the categories described below in this subsection may be used per lot."
However, Government Code section 66323, subdivision (a), states,
"Notwithstanding Sections 66314 to 66322, inclusive, a local agency shall
ministerially approve an application for a building permit within a residential or
mixed -use zone to create any of the following: (1) One accessory dwelling unit
and one junior accessory dwelling unit per lot with a proposed or existing single-
family dwelling ... (A) The accessory dwelling unit or junior accessory dwelling
unit is within the proposed space of a single family dwelling or existing space of
a single-family dwelling or accessory structure." Paragraph (2) permits "[o]ne
detached, new construction, accessory dwelling unit that does not exceed four -
foot side and rear yard setbacks." The use of the term "any" followed by an
enumeration of by -right ADU types permitted means that any of these ADU
types found in section 66323 can be combined on a lot zoned for single-family
dwellings.
This permits a homeowner, who meets specified requirements, to create one
converted ADU; one detached, new construction ADU; and one JADU. Thus, if
the local agency approves an ADU that is created from existing (or proposed)
space, and the owner subsequently applies for a detached ADU that meets the
size and setbacks pursuant to the subdivision, the local agency cannot deny the
permit, nor deny a permit for a JADU under this subdivision.
This subdivision applies equally to ADUs created pursuant to Government Code
section 66323, subdivisions (a)(3) and (a)(4) on lots with proposed or existing
multifamily dwellings. Limiting residential lots to one ADU would prevent
property owners from creating ADUs by -right under subdivision (a) of section
66323 of the Government Code.
34-42
Therefore, the City must remove the restriction on the combination of units
authorized by state law.
4. Section 20.48.200 DA & D.4.a.iii. — Multi -Unit Detached ADUs — The Ordinance
states, "For the purposes of this section, a multi -unit development approved and
built as a single complex shall be considered one (1) lot, regardless of the
number of parcels." However, Government Code section 66323, subdivision
(a)(3)(A) requires that at least one ADU be permitted on a lot with a multifamily
dwelling. Moreover, the 2022 California Building Code defines "lot" as "A portion
or parcel of land considered as a unit." The City incorrectly limits the number of
parcels within a `lot' which could result in a limitation on the number of ADUs on
parcels. This could have the effect of limiting the number of ADUs allowable on
parcels with multifamily units owned as separate interests. Therefore, the City
should remove the restriction on parcels.
5. Section 20.48.200 F. — Development Standards — The Ordinance requires ADUs
and JADUs to "conform to all objective standards of the underlying residential
zoning district, any applicable overlay district, and all other applicable
provisions..." However, Government Code section 66317, subdivision (c)
precludes local ordinance, regulation or policy not contained within the City's
ADU ordinance from being the basis of delay or denial of an ADU or JADU
permit application. While Government Code section 66314, subdivision (d)(8)
refers to local building code standards, zoning and design standards that exist
outside of the City's ADU ordinance cannot be imposed on ADUs. Moreover,
local design standards provided by the Ordinance pursuant to Government
Code sections 66314 — 66322 may not preclude the development of ADUs
created per section 66323, as noted above. Therefore, the City must amend its
ordinance to remove requirements that ADUs conform to underlying zoning
standards, and `other' unspecified provisions not in the ADU ordinance.
6. Section 20.48.200 F.2.b. —Building and Demolition Permits —The Ordinance
states, "For an accessory dwelling unit that will replace a detached garage, the
building and demolition permits shall be reviewed and issued concurrently." The
City should amend the Ordinance to specify that building, and demolition
permits are reviewed and issued concurrently for JADUs as well.
7. Section 20.48.200 F.3. — Building Height — The Ordinance requires attached
ADUs to "comply with the height limit as required by underlying zoning district."
While this appears to comply with State ADU Law, Government Code section
66321, subdivision (b)(4)(D) precludes a local agency from requiring less than
"A height of 25 feet or the height limitation in the local zoning ordinance that
applies to the primary dwelling, whichever is lower, for an accessory dwelling
unit that is attached to a primary dwelling. This subparagraph shall not require a
local agency to allow an accessory dwelling unit to exceed two stories." The
City's Ordinance does not reflect the 25 feet height minimum. Moreover, it is
34-43
unclear whether this requirement would permit a second story. The City should
clarify these sections to ensure building heights and stories for attached ADUs
are not unduly restricted.
8. Section 20.48.200 F.4.a. — ADU Size Maximum — The Ordinance limits the
maximum unit size of attached and detached ADUs. However, Government
Code section 66323, subdivision (a)(4), which applies to detached ADUs on lots
with multifamily dwellings, does not have a size maximum. ADUs and JADUs
created per section 66323 are not subject to the City's objective zoning
standards, including size. The City's size maximum in this section therefore
cannot limit detached ADUs allowed under section 66323. The City must amend
the Ordinance to note the exception for detached ADUs allowed under section
66323.
9. Section 20.48.200 F.4.e. — JADU Minimum Size — The Ordinance requires a
JADU to be a minimum size of an efficiency dwelling unit. While an ADU is
defined as also including an efficiency dwelling unit, a JADU does not contain
such a provision. While the maximum JADU size is 500 sq ft, a minimum JADU
size is determined by applicable building and residential codes as the minimum
room size plus an efficiency kitchen. Projects subject to the Supplement to the
2022 California Building Standards Code (CBC), section R304.1 through R304.3
of the California Residential Code (CRC), and sections 1208.1 through 1208.4
of the CBC, respectively, should be considered before applying a minimum
JADU size. Since a minimum size of a JADU might be less than the minimum
size of an efficiency dwelling unit, the City should amend the Ordinance to
reflect the valid minimum size allowed for a room.
10. Section 20.48.200 F.8.e. — Replacement Parking — The Ordinance affirms that
when off-street covered parking is demolished in conjunction with an ADU,
"those off-street parking spaces are not required to be replaced." This
substantially complies with State ADU Law. However, JADUs must only comply
with "applicable building standards," and do not require "additional parking" as a
condition for obtain a building permit.' JADUs must only comply with the
development standards set forth in JADU Law.2 The City's ordinance does not
expressly exempt JADUs from replacement parking when a garage is converted
as part of the enclosed use within the residence permitted by law.3 This creates
confusion and indicates the City may require replacement parking when covered
parking is converted into a JADU, which is inconsistent with the Law. Therefore,
the City must amend this section to specifically exclude JADUs from
replacement parking.

11. Section 20.48.200 H.1. —Separate Conveyance — The Ordinance states, "An
accessory dwelling unit or junior accessory dwelling unit may be rented, but no
accessory dwelling unit or junior accessory dwelling unit may be sold or
otherwise conveyed separately..." However, Government Code section 66341
provides for the sale or separate conveyance of ADUs. The City must amend
the ordinance to allow for the sale or separate conveyance of ADUs.
12. Section 20.48.200 H.3. — Owner Occupancy— The Ordinance requires owner
occupancy requirements on ADUs. Assembly Bill 976 (Chapter 751, Statutes of
2023) amended Government Code section 66315 to prohibit owner -occupancy
requirements. "No additional standards, other than those provided in Section
66314, shall be used or imposed, including an owner -occupant requirement..."
The City must remove these occupancy restrictions from the Ordinance.
13. Section 20.48.200 1. — Deed Restrictions — The Ordinance requires a deed
restriction for ADUs. Government Code section 66333, subdivision (c) requires
the recordation of a deed restriction for JADUs, which are limited to restricting
the sale of the JADU separate from the single-family residence. Government
Code section 66315 requires that no additional standards, other than those
provided in Government Code Section 66314, shall be used, or imposed on
accessory dwelling units. Deed restrictions are not authorized under state law
for ADUs. The City may not require a deed restriction prior to and as a condition
of approval of an ADU building permit application. Therefore, the City must
amend the Ordinance to remove the requirement of a deed restriction on ADUs.
The City has two options in response to this letter.4 The City can either amend the Ordinance
to comply with State ADU Laws or adopt the Ordinance without changes and include findings
in its resolution adopting the Ordinance that explain the reasons the City believes that the
Ordinance complies with State ADU Law despite HCD's findings.6 If the City fails to take either
course of action and bring the Ordinance into compliance with State ADU Law, HCD must
notify the City and may notify the California Office of the Attorney General that the City is in
violation of State ADU Law.

DISCUSSION
Background
On February 14, 2023, the City Council adopted Ordinance No. 2023-2, the City's most
recent amendment to the ADU ordinance. The ADU Ordinance Summary Matrix provides
an outline of the current ADU regulations (Attachment No. PC 2). Subsequent to its
adoption, the ordinance was submitted to the California Department of Housing and
Community Development (HCD) on February 18, 2023, pursuant to Government Code
Section 66326, which requires local governments to submit their adopted ADU
ordinances for review by the HCD within 60 days of adoption.
In 2024, the California Legislature adopted a group of housing bills aimed at addressing
the housing crisis. The legislature approved, and the Governor signed, Senate Bill (SB)
SB 477 (Chapter 7, Statutes of 2024), Assembly Bill (AB) AB 2533 (Chapter 834, Statutes
of 2024), and SB 1211 (Chapter 296, Statutes of 2024) into law that, among other things,
amended Government Code Section 66310 through 66342 to impose new limits on the
City to regulate ADUs and JADUs. In adopting these new regulations, the State
Legislature determined that these changes are a matter of statewide concern, rather than
a municipal affair. This determination allows the State to apply these new ADU laws to
charter cities. The State Legislature intends to reduce regulatory barriers and costs,
streamline the approval, and expand the potential capacity for ADUs and JADUs in
response to California's housing shortage.
The City Council adopted a revision to the City's 6t" Cycle (2022-2029) Housing Element
on September 24, 2024, and submitted it to HCD for recertification. This recertification
triggered HCD's review of the City's ADU regulations.
On October 1, 2024, HCD completed its review of the ADU ordinance and issued a letter
titled "Review of Newport Beach's Accessory Dwelling Unit (ADU) Ordinance under State
ADU Law (Gov. Code, §§ 66310 — 66342)" (HCD Letter) stating that the City's current
ADU ordinance does not comply with State ADU Law governing ADUs. The HCD Letter
is included as Exhibit "C" to Attachment No. PC 1. The HCD letter outlined the various
components of the City's ADU ordinance that HCD believes are not in compliance with
State ADU Law. In its letter, HCD directs the City to update its ADU Ordinance to comply
with State ADU Law or provide findings as part of a resolution that justify why the City's
existing Ordinance is consistent with State ADU Law. If the City fails to take either course
of action, HCD will notify the City and potentially the California Office of the Attorney
General that the City is in violation of State ADU Law.
On October 25, 2024, the City of Newport Beach Community Development Department
issued a letter to HCD in response to their review of the ADU ordinance. In its letter, the
City affirmed its commitment to addressing the required revisions to the City's ADU
Ordinance to comply with current State ADU Law (i.e. SB 477, AB 2533, and SB 1211).

Proaosed Amendments
In order to address comments received by HCD and bring the City's ADU ordinance into
compliance with State ADU Law, the City of Newport Beach needs to adopt ordinances
revising Sections 20.48.200 (Accessory Dwelling Units) and 21.48.200 (Accessory
Dwelling Units) of the Newport Beach Municipal Code (NBMC). Although the titles of said
sections reference ADUs, these sections also govern JADUs.
Summary of Changes to State ADU Laws
SB 477 (Chapter 7, Statutes of 2024) made changes to the numbering of the sections of
Government Code for State ADU and JADU Laws. The bill went into effect on March 25,
2024.
AB 2533 (Chapter 834, Statutes of 2024) made various changes to State ADU Law (Gov.
Code, § 66332) regarding unpermitted ADUs, which the City currently implements
through its existing SAFE ADU Program. The City's SAFE ADU program is an initiative
designed to help homeowners legalize existing unpermitted ADUs constructed before
January 1, 2020. The program helps homeowners address potential code enforcement
issues, liability concerns, and safety risks associated with unpermitted units. This bill went
into effect on January 1, 2025, and the City's SAFE ADU program has already been
updated to comply with the provisions.:
SB 1211 (Chapter 296, Statutes of 2024) made various changes to State ADU Law (Gov.
Code, §§ 66313, 66314, 66323) with regard to replacement parking and special
streamlined units referred to as "66323 Units" (described below) on lots with existing or
proposed multifamily dwellings. SB 1211 went into effect on January 1, 2025. This bill:
• Defines "livable space" as a space in a dwelling intended for human habitation,
as the term appears in Government Code sections 66313, subdivision (e), and
66323, subdivision (a)(3)(A).
• Specifies that uncovered, off-street parking spaces demolished in conjunction
with the construction of an ADU do not need to be replaced.
• Authorizes up to eight detached ADUs on a lot with an existing multifamily
dwelling (previously limited to two), provided that the number of ADUs does not
exceed the number of existing units on the lot.
• Prohibits a local agency from imposing any objective development standards on
66323 Units that are not authorized by the provisions of Government Code
section 66323, subdivision (a).
34-51
Accessory Dwelling Unit Ordinance Update (PA2025-0093)
Planning Commission, July 17, 2025

SB 1211 established "66323 Units" under Government Code Section 66323 and clarifies
four categories of ADUs (and JADUs) that must be approved ministerially and are not
subject to standards set forth in Government Code Sections 66314 through 66322 or the
NBMC (i.e. "66323 Units"). These 66323 Units do not have to comply with the City's
objective development and design standards, such as height, setbacks, and size limits.
These ADUs must still comply with building code and health and safety requirements.
Below is a breakdown of the four categories of 66323 Units and the minimal standards
that cities are allowed to apply to them.
1. Single -Unit Internal ADUs and JADUs
• One ADU per lot is permitted within the converted space of a proposed or
existing single -unit dwelling or accessory structure.
• No additional setbacks are required beyond that of the existing or proposed
structure and any applicable building and safety minimum requirements.
• ADUs converted from accessory structures are eligible for a 150 square -
foot expansion to accommodate ingress and egress.
• One JADU per lot is permitted within the proposed or existing space of a
single -unit dwelling or accessory structure.
2. Single -Unit Detached ADUs
• One detached new construction ADU is permitted on lots with an existing or
proposed single -unit dwelling.
• 4-foot side and rear yard setbacks are allowed.
• The maximum unit size is 800 square feet.
• Height limitation of 16 or 18 feet depending on conditions specified in
Government Code Section 66321, subdivision (b)(4).
3. Multi -unit Converted ADUs
Conversion ADUs may be created within the portions of existing multi -unit
structures that are not used as livable space.
At least one ADU is within an existing multi -unit dwelling and up to 25% of
the existing multi -unit dwelling units.
4. Multi -unit Detached ADUs
Two detached ADUs are allowed on a lot with a proposed multi -unit
dwelling, or up to eight detached ADUs are allowed on a lot with an existing
multi -unit dwelling, not to exceed the number of existing units on the lot.
4-foot rear and side yard setbacks are allowed.
Height limits of 16, or 18 feet depending on conditions specified in
Government Code Section 66321, subdivision (b)(4).

HCD Letter
Table 1 below summarizes the comments received by HCD as part of their review of the
City's ADU ordinance (i.e. HCD Letter) and identifies how the City proposes to address
those comments. The comments received by HCD are intended to guide the City in
addressing the State ADU law changes that went into effect on March 27, 2024, and
January 1, 2025. As requested by HCD, the draft resolution (Attachment No. PC 1)
includes findings addressing why certain changes requested by HCD are not necessary
to comply with State ADU Law. All other suggested changes have been made in the
proposed ordinance (Attachment No. PC 3). Redlines of Sections 20.48.200 and
21.48.200 of the NBMC addressing the HCD Letter are included as Attachments No. PC
3 and PC 4.

HCD Review
Government Code Section 66326 requires the City to submit the ordinance to the State
Department of Housing and Community Development (HCD) within 60 days of adoption.
Should the City Council approve the proposed ordinance to amend Title 20, staff will
forward the ordinance to HCD for review. If HCD finds the ordinance does not comply
with the new ADU laws, HCD will notify the City. Should this occur, the City would have
30 days to either amend the ordinance or adopt additional findings that explain the reason
the ordinance complies with the statute. Since the amendment to Title 21 requires CCC
approval, the ordinance amending Title 21 will be submitted to HCD after the CCC LCPA
process is complete.
General Plan Consistency
The law states that ADUs shall be deemed an accessory use and shall not be considered
to exceed the allowable density for the lot upon which it is located and shall be deemed
a residential use that is consistent with the existing general plan and zoning district for
the lot. Therefore, no amendments to the General Plan are required.
Adopting an ordinance consistent with Government Code Sections 66310 through 66342
ensures and reinforces the commitment that the City has made to promote and incentivize
ADU growth via the established Policy Action 1 H: Accessory Dwelling Unit Construction
of the City's 2021-2029 Housing Element.
Local Coastal Plan
Similar to the Zoning Code, the Implementation Plan of the Local Coastal Program (LCP)
currently regulates ADUs inconsistent with State ADU law. Therefore, subsequent to City
Council adoption of this Zoning Code Amendment, staff will submit corresponding
amendments (Attachment No. PC 4) to the LCP for review and approval of the CCC. In
accordance with CCC Guidance Memorandums, any eligible projects located in the
Coastal Zone that qualify for a Coastal Development Permit (CDP) exemption will be
processed consistent with the Zoning Code. Projects that do not qualify for an exemption
cannot be processed until the LCP Amendment is approved and adopted.
By adopting an ordinance amending the Local Coastal Program, the City will continue to
implement Local Coastal Program Policy 2.7-5, which encourages consistency with
Government Code Sections 66310 through 66342 for the purposes of increasing the
supply of lower -cost housing in the coastal zone that meets the needs of existing and
future residents, while respecting the architectural character of the existing
neighborhoods and in a manner that is consistent with the Local Coastal Program.
Reducina the Barriers to the Creation of Housin
The City Council adopted a policy (Council Policy K-4) to consider new and flexible land
use and zoning regulations and strategies in order to reasonably and practically
34-56
Accessory Dwelling Unit Ordinance Update (PA2025-0093)
Planning Commission, July 17, 2025
Page 9
accommodate the ambitious State housing mandate while protecting the character and
maintaining a quality of life that makes Newport Beach a special place to live, work, and
visit.
One of the ways Council Policy K-4 achieves that goal is by encouraging the development
of accessory dwelling units and junior accessory dwelling units as an important strategy
to accommodate future growth and is an integral strategy to help meet the City's Regional
Housing Needs Allocation (RHNA) of 4,849 units. Adopting an ordinance to address State
ADU Law revisions is consistent with Council Policy K-4 which encourages the
development of accessory dwelling units as an important strategy to accommodate future
growth and is an integral strategy to help meet the City's RHNA.
Altarnafivac
The Planning Commission may recommend revisions to the draft ordinance provided the
revisions are consistent with State ADU law and are not more restrictive than the State's
regulations pertaining to ADUs and JADUs. Noncompliance with State ADU law would
render the City's ADU ordinance null and void, thus requiring the City to utilize the State's
more lenient ADU standards until the City modifies its regulations appropriately.
Environmental Review
The project is exempt from environmental review under the California Environmental
Quality Act (CEQA) pursuant to Public Resources Code Section 21080.17 and CEQA
Guidelines Section 15282(h), which states that the adoption of an ordinance regarding
second units to implement the provisions of Sections 66310 through 66342 of the
Government Code are exempt from the requirements of CEQA. Similarly, the ministerial
approval of ADUs would not be a project for CEQA purposes, and environmental review
would not be required prior to approving individual applications. In addition, pursuant to
CEQA Guidelines Section 15265(a)(1), local governments are exempt from the
requirements of CEQA in connection with the adoption of a Local Coastal Program.
Public Notice
Notice of this hearing was published in the Daily Pilot as an eighth page advertisement at
least 20 days before the scheduled meeting, consistent with the provisions of the
Municipal Code and State Law. The item also appeared on the agenda for this meeting,
which was posted at City Hall and on the City website. Additionally, notice was sent to all
persons and agencies on the Notice of the Availability mailing list for LCPAs.

V. PUBLIC COMMENTS
Jim Mosher noted approval of minutes from the July 3rd meeting is not on tonight's agenda,
expressing hopes they were delayed and not nonexistent. He reported at the July 3rd meeting that
a Commissioner told the public not to blame the Planning Commissioners for their decisions
because their role is black and white in only deciding if a project meets the Newport Beach
Municipal Code (NBMC). He added that this sort of decision is considered ministerial and left to
City staff, whereas projects coming to the Planning Commission require judgment and discretion.
He noted Assistant City Attorney Yolanda Summerhill stated at the meeting that State laws limit 34-59

the City's discretionary abilities regarding multi -family housing, but added the Commissioners still
maintain some level of discretion.
VI. REQUEST FOR CONTINUANCES — None
In response to Chair Harris' inquiry, Deputy Community Development Director Jaime Murillo
clarified that the transcription service, which would have provided the July 3rd minutes, was
unavailable to complete them in time for this meeting. He reported that at the next meeting, he
expects to have two sets of minutes to review and approve.
VII. PUBLIC HEARING ITEMS
ITEM NO. 2 TRACY RESIDENCE VARIANCE (PA2023-0200)
Site Location: 1020 White Sails Way
Summary:
A request for a variance to allow an addition to an existing single -unit dwelling to encroach
into the required 50-foot front setback. Specifically, the applicant requests to construct a new
attached three -car garage that will encroach 29 feet into the front setback with a roof
overhang that encroaches 31 feet into the front setback and a new bedroom addition that will
encroach 13 feet into the front setback. The project also includes a new basement level
vestibule, machine room, and elevator attached to the three -car garage that does not
encroach into the front setback. The proposed garage would replace the existing two -car
garage and would be located below the existing grade. The existing two -car garage would
be converted into living space. The project also includes the removal of several existing
unpermitted structures including a detached storage room, walls, fences, stairs, and other
accessory structures that were constructed without the benefit of a building permit. No other
deviations to the development standards are proposed.
Recommended Actions:
1. Conduct a public hearing;
2. Find this project exempt from the California Environmental Quality Act (CEQA)
pursuant to Section 15301 under Class 1 (Existing Facilities) and Section 15305
under Class 5 (Minor Alterations in Land Use Limitations) of the CEQA Guidelines,
because it has no potential to have a significant effect on the environment; and
3. Adopt Resolution No. PC2025-013 approving the Variance filed at PA2023-0200.
Associate Planner Jenny Tran reported that the project is located at 1020 White Sails Way in the
Harbor View Hills area of Corona del Mar. She noted properties in this neighborhood have varying
front setbacks, and this project is requesting an encroachment into a large 50-foot front setback..
Associate Planner Tran reported on the timeline for the project, which originally was submitted as
a Zoning Code Amendment request on May 8, 2023, but was removed from the calendar due to
a lack of support from the Homeowners' Association (HOA). She reported the applicant filed a
project -specific variance request on December 19, 2023, but removed it from the calendar on May
8, 2024. She reported that on May 24, 2024, a Code Enforcement case was opened due to
unpermitted construction at the site, leading to a June 4, 2024, site visit confirming the unpermitted
construction. She reported this hearing will address the unpermitted construction in addition to
the previous variance request.
Associate Planner Tran reported on the unpermitted construction, which also includes a fence
exceeding the permissible height and a garage not meeting the required dimensions. She
reported that the variance request is to remove the unpermitted construction and for permission
to build a new three -car garage 29 feet into the setback and a bedroom addition 13 feet into the 34-60
Docusign Envelope ID: 47010550-F784-46D7-B2D7-05810B6B5078

setback.
Associate Planner Tran reported facts in support of the variance are a steep driveway, safety
concerns about sightlines pulling out of the driveway, the widely staggered setbacks in the
neighborhood ranging from 13 to 52 feet, and neighborhood compatibility, as most houses in the
area have straight -in driveways. She added that Conditions for Approval in the Resolution include
the removal of all unpermitted construction unless permits are obtained complying with the NBMC,
all fences, hedges, walls, and retaining walls must comply with the NBMC, and a hold on final
inspection to ensure all unpermitted construction is addressed.
In response to Secretary Langford's inquiries, Associate Planner Tran clarified that the removal
of the sloped driveway means the garage is now at sidewalk level, which makes it below the
previously existing grade. She reported there is an elevator going up from the garage to the main
residence, adding it is located behind the existing 50-foot setback.
In response to Vice Chair Salene's inquiries, Associate Planner Tran confirmed that the house
two doors down is built 52 feet from the property line. She confirmed that 1014 White Sails Way
is the neighbor on the other side of the house.
In response to Commissioner Reed's inquiry, Associate Planner Tran confirmed all the other
homes in the neighborhood have straight driveways and not the diagonal one this house
previously had.
In response to Chair Harris' inquiry, Associate Planner Tran reported that staff were unable to
determine why the driveway was originally built at an angle to the street. She added that the deep
setbacks are most likely a benefit to the views in the neighborhood..
In response to Vice Chair Salene's inquiry, Associate Planner Tran reported that the HOA has
written a conditional approval letter, which is included in the staff report.
All Commissioners reported having no ex Parte communications.
Chair Harris opened the public hearing.
Architect Ron Thorpe, speaking on behalf of applicant Mike Tracy, recommended approval.
In response to Chair Harris' inquiry, Mr. Thorpe agreed with the Conditions of Approval.
Mary Ann Soden, Chair of the Harbor View Hills Architectural Review Committee, expressed the
HOA's support of the resolution. She reported that the lots and setbacks were created in the
1950s to ensure the homes complement each other and do not block views. She stated that
moving the setbacks for the garage and bedroom addition is harmonious with the community. She
added that the HOA has worked with the Planning Division to ensure alignment with the NBMC.
Mr. Mosher stated it is extraordinary that the applicant withdrew their variance request and then
followed through with the project as if the Commission had granted approval. He inquired if there
were consequences for this action. He questioned the purpose of the wall, causing the obstructed
view while exiting the original driveway path, and if it will be lowered as part of this resolution.
Chair Harris closed the public hearing.
Deputy Community Development Director Murillo clarified that the wall referenced by Mr. Mosher
is the applicant's neighbor's wall. He added that the City cannot make the neighbors lower the
wall, but added that any new construction would have to comply with the City's sight view
standards.
In response to Chair Harris' inquiry, Deputy Community Development Director Murillo confirmed 34-61
Docusign Envelope ID: 47010550-F784-46D7-B2D7-05810B6B5078

that the City opened a Code Enforcement case against the applicant because of the unpermitted
work, and the applicant will have to produce plans to work through the issues created.
Secretary Langford stated he is not inclined to approve variances for a community whose lot
layout is both deliberate and dated to the 1950s. He added he is also not inclined to approve a
variance encouraging bad behavior, where residents can build what they want without requesting
the City's permission. He stated the garage being below grade makes sense under the
circumstances, but he has issues with the bedroom addition as it enters the setback, while
potentially blocking the carefully created views of other residences. He pondered whether the
garage and bedroom must be a packaged deal. He lamented being asked to approve a project
that had already been built behind the City's back.
Vice Chair Salene stated that a 50-foot setback on a 150-foot lot is extreme and is among the
largest on the street. He noted the bedroom addition would meet the City's standards, and the
HOA is supportive, leading him to support the project despite his reservations about rewarding
bad behavior.
Commissioner Reed agreed with Vice Chair Salene and expressed his support for the inspection
prior to approval to ensure the unpermitted construction is removed so the project meets the
NBMC.
Chair Harris stated the applicant is somewhat penalized for having a larger lot than some of the
neighbors and the only sloped driveway. He stated the findings support the safety aspect of a
driveway reconstruction. He added that the behavior of the applicant was initially bad, but they
are doing the right thing now, and he is inclined to support the variance.
Motion made by Chair Harris and seconded by Commissioner Reed to approve the Item as
recommended.

ITEM NO. 3 ACCESSORY DWELLING UNIT ORDINANCE (PA2025-0093)
Site Location: Citywide
Summary:
Amendments to Title 20 (Zoning Code) and Title 21 (Local Coastal Program Implementation
Plan) updating regulations pertaining to Accessory Dwelling Units (ADU) and Junior
Accessory Dwelling Units (JADU) to conform with revisions to Government Code Sections
66310 through 66342 that went into effect on March 27, 2024, and January 1, 2025.
Recommended Actions:
1. Conduct a public hearing;
2. Find this project statutorily exempt from the California Environmental Quality Act
(CEQA) pursuant to Section 15282(h) of the CEQA Guidelines, which states that the
adoption of an ordinance regarding second units to implement the provisions of
Sections 66310 through 66342 of the Government Code are exempt from the
requirements of CEQA and pursuant to CEQA Guidelines Section 15265(a)(1), local
governments are exempt from the requirements of CEQA in connection with the
adoption of a Local Coastal Program;
3. Adopt Resolution No. PC2025-014, recommending the City Council approve

Program Amendment (LCPA) and authorize staff to submit the LCPA to the
California Coastal Commission (CCC).
Associate Planner Oscar Orozco reported that the City adopted its Accessory Dwelling Unit (ADU)
Ordinance in 2017 and has been updated several times, particularly to address changes in State
law. He added that it was last updated in February 2023, with part of the update being the creation
of a website with resources about ADUs for residential reference. He reported the City currently
has 238 ADUs, including ones finalized, under construction or under review.
Associate Planner Orozco reported three bills passed by the State in 2024 addressing ADUs
require changes to the City's policies, with the most significant change being the provision in
Senate Bill 1211, which allows for up to eight detached ADUs on lots with existing multifamily
dwellings, an increase from just two but not to exceed the existing unit count. He added that the
California Department of Housing and Community Development (HCD) informed the City during
the Housing Element recertification process that it needs to update its ADU policy to reflect recent
legislative changes.
Associate Planner Orozco stated that the proposed changes to the ADU ordinance are designed
to comply with the General Plan, Local Coastal Plan Amendment (LCPA), and City Council
policies. He added that the City will continue to encourage and incentivize ADU growth, along
with encouraging lower -cost housing to help meet the City's Regional Housing Needs
Assessment (RHNA) quotas.
Associate Planner Orozco reported the City received a letter from the California Housing Defense
Fund (HDF) during the public comment period, noting the City insufficiently addresses the
allowance of up to eight detached ADU state law change, but added the City feels it is adequately
addressed in the draft resolution. He commented that the historic resources standards comment
from HDF have led to an additional change to the Draft Resolution, specifically by removing the
first sentence from Section 20.48.200(J) and Section 21.48.200(K) and moving the section under
the ADU development standards section of title 20 and 21.
Vice Chair Salene reported that the City's ADU website was extremely helpful when he was
building an ADU.
In response to Vice Chair Salene's inquiry, Associate Planner Orozco confirmed that staff feels it
has properly addressed the needed changes outlined by HDF.
In response to Chair Harris' inquiries, Associate Planner Orozco confirmed that the phrase "off-
street uncovered parking" refers to driveways. He clarified that unless a setback is specifically
listed as required, the ADU would only be required to comply with Section 66323 of the State's
Code. He confirmed that, hypothetically, if the City has a mandatory 20-foot setback, an ADU
would have to comply with it. He confirmed that multi -family properties can now turn carports into
ADUs without having to replace the parking spaces. He added that parking is not changing in the
City's coastal zones due to other State laws. He confirmed, outside of the coastal zone, an eight -
unit development can turn eight carports into ADUs and not have to find eight new parking spaces.
He clarified that "non -habitable space" refers to areas such as storage rooms or mechanical
equipment rooms. He clarified that the conversion of existing space is limited to two ADUs per
multi -dwelling property, while the new standard of eight applies to detached ADUs. He added that
this process can still eliminate up to two parking spaces.
All Commissioners reported having no ex Parte communications.
Chair Harris opened the public hearing. Being no speakers, the public hearing was closed.
Motion made by Vice Chair Salene and seconded by Chair Harris to approve the Item as
recommended.

COYOTE CANYON LAN DFGI LL-GAS-TO-EN ERGY (PA2022-063)
Site Location: 20662 Newport Coast Drive
Summary:
A request for a conditional use permit to allow the construction and operation of a new
renewable natural gas processing plant and pipeline interconnection facility. The facility
would convert landfill gas from the closed Coyote Canyon Landfill into a pipeline -quality
natural gas equivalent, which would be transferred into SoCal Gas infrastructure through an
existing onsite tie-in point. Additional project components include a new control room
building, new internal access routes, utility upgrades including installation of an additional fire
hydrant, a water tank, a septic tank, a storm drain for off -site disposal of stormwater, and new
underground power and telecommunication lines. The facility would operate 24 hours a day,
seven days a week, with one scheduled annual shut down for maintenance. Existing onsite
telecom facilities approved under PA2016-091 (SCH No. 2016081012) would remain in place
and be unaffected by this application. This project was originally noticed for a Planning
Commission meeting on May 22, 2025, and was removed from calendar. There have been
no changes to the project since the previous Notice of Public Hearing.
Recommended Actions:
1. Conduct a public hearing; and
2. Adopt Resolution No. PC2025-008, adopting the Mitigated Negative Declaration
(SCH NO. 2024120012) and approving the Conditional Use Permit filed under
PA2022-063.
Senior Planner Joselyn Perez used a PowerPoint to present the project location, zoning and
surrounding land uses, background of the Coyote Canyon landfill, existing site conditions, a
project description, summarized the environmental review process which included preparing an
Initial Study/Mitigated Negative Declaration (IS/MND), Mitigation Monitoring and Reporting
Program, and Response to Comments received on the IS/MND. She concluded her presentation
by summarizing the project, reviewing the written comment letter provided by the law firm Adams
Broadwell Joseph Cardozo prior to public hearing, and indicated that the comments reflect those
already received during the IS/MND public comment period which were adequately responded to
in the Response to Comments portion of the IS/MND.
In response to Commissioner Langford's inquiry, Senior Planner Perez confirmed there are no
public trails through the area, and the property surrounding the site is owned by the City of Irvine.
Assistant City Attorney Summerhill added that there has been some discussion about adding bike
and/or pedestrian trails, but it has not been brought to fruition.
All Commissioners reported having no ex Parte communications.
Chair Harris opened the public hearing.
Tyler Henson, Lead Manager of External Affairs for Archaea Energy, reported that they will be
partnering with Orange County Waste and Recycling on the Coyote Canyon project, and Archaea
is the largest RNG producer in the country. He presented on the company's safety protocols and
benefits of RNG being collected from landfill gas, which would otherwise be burnt off. He
acknowledged there will be temporary impacts during construction but expressed a commitment
to work with the City throughout the process, adding they have already discussed the project with

Sage Hill School regarding working the site's traffic around school drop-off and pickup times. He
presented artist renderings of the completed facility.
In response to Chair Harris' inquiry, Mr. Henson confirmed Archaea agrees with the
recommended Conditions of Approval.
In response to Commissioner Reed's inquiries, Mr. Henson reported that construction timelines
could range between one and five years, depending on variables including the permitting process.
He added they cannot offer a definitive timetable for how long the facility will operate, as it is
determined by gas levels.
In response to Secretary Langford's inquiry, Mr. Henson reported Archaea works with the local
jurisdictions regarding the look of their site, adding their appearance can vary widely depending
primarily on the remoteness of the locations. He expressed a willingness to work with Newport
Beach on the facility's outward appearance.
In response to Vice Chair Salene's inquiries, Mr. Henson confirmed he has seen the comment
letter from the law firm referenced earlier by Senior Planner Perez and stated City staff's response
to the letter is sufficient. He expressed a willingness to put non-interference with school traffic
patterns into writing as a Condition of Approval.
Aidan Marshall, speaking on behalf of Orange County Residents for Responsible Development,
requested that staff prepare a full Environmental Impact Report (EIR) instead of an MND for
CEQA compliance and to protect the health and safety of residents and workers. He stated his
organization has responded in writing throughout the process with analysis from air quality and
noise consultants agreeing the project would result in significant unmitigated air quality, public
health, and noise impacts left unaddressed in the MND. He added that there are also health
hazards to analyze and mitigate from a potential emergency at the facility, impacting its safe
operation.
Mr. Mosher expressed concerns about the project's thermal oxidizer, including the possibility of it
collapsing during an earthquake, and creating potential damage to land owned by the City of
Irvine.
Assistant City Attorney Summerhill confirmed staff received the letter submitted by Adams
Broadwell Joseph Cardozo and feels the comments had been adequately addressed. She added
that there is a CEQA consultant who can further respond.
Senior Engineer and project manager Dina El Chammas Gass, on behalf of PlaceWorks,
confirmed that none of the comments in the Adams Broadwell Joseph Cardozo letter are new and
have been previously responded to. She noted that the letter states there could be significant and
unavoidable impacts, which is incorrect. She added that the off -site consequences analysis
prepared for the project showed no significant impacts. She continued that the IS/MND includes
a mitigation measure to enact a fuel modification plan to mitigate fire risks. She made note of the
need to remove 28 trees at the request of the Newport Beach Fire Department to support the goal
of preventing a fire in the facility from spreading beyond its walls or vice versa and mitigating fire
risk. She reported the RNG Facility itself will be designed with many monitors and sensors to help
ensure its safe operation and mitigate fire risk. Ms. El Chammas Gass noted there was a comment
made about noise and added that a Noise Analysis was conducted for this project, which is
included in the IS/MND, and sufficiently addresses that comment.
Principal Nicole Vermilion, on behalf of PlaceWorks, clarified that the facility will have a closed
system, so there will be no fugitive emissions unaddressed by the air quality permit through the
South Coast Air Quality Management District (AQMD). She noted the South Coast AQMD is listed
as a responsible agency, so it will have to approve the project along with Newport Beach. She
expressed confidence in the conclusions of the MND. 34-65

Senior Planner Perez stated, in response to Secretary Langford's earlier inquiry about the facility's
exterior, staff reviewed both a light blue and camouflage print option for the exterior, with a final
design to be determined in plan check. In response to Vice Chair Salene's earlier inquiry about
Sage Hill School, she reported that staff have put a mitigation measure into the MND requiring a
traffic control plan sensitive to the school.
Chair Harris closed the public hearing.
Secretary Langford lauded the fact that there have been no incidents in the 30 years of operations
by the previous facility, and bringing in newer technology to the new facility. He expressed an
interest in the fuel modification plan, noting the NBFD has been doing a great job of removing
trees at risk for fire. He requested of the applicant if, in addition to removing the trees, they could
landscape to better help shield the walls from traffic on Newport Coast Drive.

There is a very narrow
exception in State ADU Law
that requires cities to allow
separate conveyance (i.e.
separate sale) of ADUs for
non -profits.
This revision is not necessary

ordinance does not require
owner occupancy of ADUs,
