The Honorable Rex Richardson,
RE: Reconvene the SCAG President’s RHNA Litigation Study Team

1) consider this and other new information from credible agencies;
2) justify how its 1.34 million housing unit determination is defensible in light of the new
information and should be fittingly revised; and,
3) justify how its 1.34 million housing unit determination is consistent with State Statute
provisions.
A prompt assessment of this information, and options to pursue resolution with State HCD,
would be invaluable and timely to SCAG’s member agencies, many of which are currently
exploring appeals of their individual RHNA allocations.
Moreover, if the SCAG President’s RHNA Litigation Study Team is reconvened, we would
strongly urge SCAG to revisit the critical issue that State HCD did not follow housing statute,
when it determined SCAG’s 1.34 million housing units need. We appreciate that SCAG raised
this concern to State HCD. W e object, however, that State HCD has chosen to not adhere to
the provisions of our Government Code, and we have provided a detailed, technical
assessment of such noncompliance in Attachment 2.
We thus respectfully seek your support and follow-through of your verbal commitment to
Council Member Huang, that the President’s RHNA Litigation Study Team be re convened to
undertake this important discussion. We look forward to your response, with the desire that the
RHNA Litigation Study Team be reconvened prior to the next SCAG Regional Council meeting,
October 1, 2020.
With sincere respect and appreciation,

Orange County Mayor's Letter to the Southern California Council of Governments (SCAG)
Orange County Technical Analysis of SCAG’s Regional Determination from HCD
Government Code Section 65584.01(a) states: “If the total regional population forecast for the
projection year, developed by the council of governments and used for the preparation of the regional
transportation plan, is within a range of 1.5 percent of the total regional population forecast for the
projection year by the Department of Finance, then the population forecast developed by the council of
governments shall be the basis from which the department determines the existing and projected need
for housing in the region….”.
As outlined in SCAG’s September 18, 2019 objection letter to the California Department of Housing and
Community Development (HCD) (see Exhibit B), SCAG’s regional population forecast for its Regional
Transportation Plan (RTP) differs from the State Department of Finance (DOF) projection by 1.32%,
which falls within the statutory range of 1.5% outlined in state law. Therefore, by statute, the regional
determination should be based on SCAG’s population projections.
However, HCD’s October 15, 2019 response letter to SCAG (see Exhibit C) cites two reasons for not using
SCAG’s total regional population forecast:
1)The total household projection from SCAG is 1.96% lower than DOF’s household projection.
2)The age cohort of under 15-year old persons from SCAG’s population projections differ from
DOF’s projections by 15.8%.
A careful reading of Government Code Section 65584.01(a) demonstrates that HCD’s interpretation and
rejection of the use of SCAG’s regional population forecast is incorrect for the following two reasons:
1)The law clearly states that that the 1.5% range is based on the total regional population forecast
and not the regional household projection forecast.
2)The law clearly states that the 1.5% range is based on the total regional population forecast and
not on age-cohort population forecasts.
While Government Code 65584.01 provides a significant level of discretion to HCD over many of the
factors used for the regional determination (i.e., vacancy adjustments, overcrowding rates, replacement
adjustments, cost-burdened adjustments, etc.), this one issue is clearly written into the law without any
discretion from HCD. Therefore, even though we support all of the arguments SCAG outlined in their
September 18, 2019 objection letter, we also recognize that state law grants HCD the final
determination for those specific factors. However, there is no discretion in HCD’s decision to ignore
SCAG’s regional population forecast. Had HCD adhered to Government Code 65584.01(a), we estimate
that the regional determination should have been at least approximately 133,000 housing units lower
(see Exhibit A), or no more than approximately 1.2 million housing units.
We would hope that HCD would reconsider the other SCAG’s recommendations as noted in their
September 18, 2020 objection letter, especially in light of the change in circumstances related to the
current COVID-19 pandemic, as well as the recent studies and reports stating that California’s statewide
housing shortfall is significantly lower than even SCAG’s entire RHNA obligation.

Mr. Doug McCauley
Acting Director
Housing & Community Development (HCD)
2020 W. El Camino Ave.
Sacramento, CA 95833
Subject: SCAG’s Objection to HCD’s Regional Housing Need
Determination
Dear Mr. McCauley,
This letter represents the Southern California Association of Governments
(SCAG)’s formal objection to HCD’s Regional Housing Need
Determination as submitted to SCAG on August 22, 2019 and is made in
accordance with Government Code Section 65584.01(c)(2)(A) and (B). At
the outset, please know that SCAG is fully aware that the State of California
is in the midst of a housing crisis and that resolving this crisis requires strong
partnerships with state, regional and local entities in addition to private and
non-profit sectors.
As such, SCAG desires to be an active and constructive partner with the State
and HCD on solving our current housing crisis, and this objection should not
suggest otherwise. We are in fact currently setting up a housing program that
will assist our local jurisdictions on activities and policies that will lead to
actual housing unit construction.
In the context of the 6th cycle Regional Housing Needs Assessment (RHNA)
process, SCAG appreciates the collaboration with HCD as reflected in the
numerous consultation sessions on the regional determination and other staff
engagement on housing issues with the objective of making RHNA a
meaningful step toward addressing our housing crisis.
As you are aware, HCD transmitted its Regional Housing Needs
Determination of 1,344,740 units for the SCAG region last month. This
number reflects the housing units that local jurisdictions in the region must
plan for during the 8-year period from October 2021 to October 2029. At
the September 5, 2019 meeting, SCAG Regional Council authorized staff to
file an objection to HCD on regional housing need determination pursuant
to Government Code Section 65584.01(c).
EXHIBIT B
Housing Element Update Advisory Committee - October 21, 2020
Item No. V(b) - Attachment 2
Orange County Mayor's Letter to the Southern California Council of Governments (SCAG)
I would like to note that SCAG’s objection focuses on the process and adherence to state housing
law requirements and not necessarily to the regional housing need determination number. The
ultimate aim of this objection, as discussed at length by the Regional Council, is to ensure the most
technically and legally credible basis for a regional determination so that the 197 local
jurisdictions in the SCAG region can approach the difficult task of zoning to accommodate
regional needs with the backing of the most robust and realistic target that is possible.
One of our major concerns is that HCD did not base its determination on SCAG’s RTP/SCS
Growth Forecast, which was inconsistent with Government Code 65584.01(c)(2)(A). Another
major concern is that pursuant to Government Code 65584.01(c) (2) (B), HCD’s determination of
housing need in the SCAG region is not a reasonable application of the methodology and
assumptions described in statute. Specifically, HCD compared household overcrowding and cost-
burden rates in the SCAG region to national averages rather than to rates in comparable regions as
statutorily required. These and two additional basis for objections are described in detail in the
section below which also includes a deduction for household growth on tribal land and a concern
that the vacancy rate standards used by HCD are not substantiated by data, analysis, or literature.
In addition, the attached EXCEL worksheet and technical documentation contain SCAG’s
alternative proposed 6th cycle RHNA determination, which would consist of a range of total
housing unit need between 823,808 and 920,772.
BASIS FOR SCAG OBJECTION
Use of SCAG’s Population Forecast
HCD did not base its determination on SCAG’s RTP/SCS Growth Forecast, which was provided
in the original consultation package and via follow-up email to HCD. Government Code
65584.01(a) indicates [emphasis added]:
“(a) The department’s determination shall be based upon population projections produced by the
Department of Finance and regional population forecasts used in preparing regional
transportation plans, in consultation with each council of governments. If the total regional
population forecast for the projection year, developed by the council of governments and used
for the preparation of the regional transportation plan, is within a range of 1.5 percent of the
total regional population forecast for the projection year by the Department of Finance, then
the population forecast developed by the council of governments shall be the basis from which
the department determines the existing and projected need for housing in the region. If the
difference between the total population projected by the council of governments and the total
population projected for the region by the Department of Finance is greater than 1.5 percent, then
the department and the council of governments shall meet to discuss variances in methodology
used for population projections and seek agreement on a population projection for the region to
be used as a basis for determining the existing and projected housing need for the region. If no
agreement is reached, then the population projection for the region shall be the population
projection for the region prepared by the Department of Finance as may be modified by the
department as a result of discussions with the council of governments.”
Housing Element Update Advisory Committee - October 21, 2020
Item No. V(b) - Attachment 2
Orange County Mayor's Letter to the Southern California Council of Governments (SCAG)
SCAG projects total regional population to grow to 20,725,878 by October, 2029. SCAG’s
projection differs from Department of Finance (DOF) projection of 20,689,591, which was issued
by DOF in May, 2018, by 0.18%. The total population provided in HCD’s determination is
20,455,355, reflecting an updated DOF projection, differs from SCAG’s projection by 1.32%. As
SCAG’s total projection is within the statutory tolerance of 1.5%, accordingly HCD is to use
SCAG’s population forecast.
While HCD has emphasized that consistency in approach to the 6th cycle RHNA across regions is
a priority, deference to the Council of Governments’ forecast as specified in statute is an important
aspect of regional planning. Federal requirements for SCAG’s Regional Transportation Plan
necessitate a forecast of population, households, and employment for evaluating future land use
patterns and measuring future travel demand as well as air quality conformity under the federal
Clean Air Act. In addition, under SB 375, the State requires SCAG to develop a Sustainable
Communities Strategy which is a coordination of transportation and land use in the regional
planning process to achieve State’s climate goals. Both federal and State requirements are
predicated on SCAG’s forecast of population, households and employment.
As a result, SCAG has a long-established and well-respected process for producing a balanced
forecast of population, households, and employment for the region, the details of which can be
found in each Regional Transportation Plan (e.g.
http://scagrtpscs.net/Documents/2016/final/f2016RTPSCS_DemographicsGrowthForecast.pdf).
SCAG’s quadrennial growth forecast begins with a consensus on appropriate assumptions of
fertility, migration, immigration, household formation, and job growth by a panel of state and
regional experts including members of DOF’s Demographic Research Unit. In addition, SCAG
co-hosts an annual demographic workshop with the University of Southern California to keep state
and regional experts and stakeholders appraised of demographic and economic trends
(https://www.scag.ca.gov/calendar/Pages/DemographicWorkshop.aspx).
SCAG places a high priority on generating its own forecasts of population, households, and
employment and ensuring the highest possible degree of consistency and integrity of its projections
for transportation, land use, and housing planning purposes.
Use of Comparable Regions
Pursuant to Government Code 65584.01(c)(2)(B), HCD’s determination of housing need in the
SCAG region is not a reasonable application of the methodology and assumptions described in
statute. Specifically, HCD compared household overcrowding and cost-burden rates in the SCAG
region to national averages rather than to rates in comparable regions as statutorily required.
SCAG’s initial consultation package provided an approach using comparable regions to evaluate
household overcrowding SCAG staff met with HCD staff in-person in both Los Angeles and
Sacramento to discuss adjustment criteria and how to define a comparable region to Southern
California, as our region’s size precludes a straightforward comparison. At the direction of HCD,
SCAG staff refined its methodology for identifying comparable regions and provided a state-of-
the-practice analysis supported by recent demographic and economic literature which determined
Housing Element Update Advisory Committee - October 21, 2020
Item No. V(b) - Attachment 2
Orange County Mayor's Letter to the Southern California Council of Governments (SCAG)
that the most appropriate comparison to the SCAG region would be an evaluation against the San
Jose, New York, San Francisco, Miami, Seattle, Chicago, San Diego, Washington D.C., Houston,
and Dallas metropolitan areas. Despite this collaboration on the subject between HCD and SCAG,
HCD elected to reject this approach and instead used national average statistics, which include
small metropolitan areas and rural areas having little in common with Southern California.
HCD’s choice to use national averages:
Is inconsistent with the statutory language of SB 828, which added the comparable region
standard to RHNA law in order to improve the technical robustness of measures of housing
need.
Is inconsistent with empirical data as economic and demographic characteristics differ
dramatically based on regional size and context. For comparison, the median-sized
metropolitan region in the country is Fargo, North Dakota with a population of 207,500. That
is not a meaningful basis of comparison for the nation’s largest MPO.
Is inconsistent with HCD’s own internal practice for the 6th cycle of RHNA. The regional need
determination for the Sacramento Area Council of Governments (SACOG), issued on July 18,
2019, was the first 6th cycle RHNA determination following SB 828’s inclusion of the
comparable region standard. During their consultation process with HCD, SACOG also
produced a robust technical analysis to identify comparable regions for the purposes of using
overcrowding and cost-burden statistics to determine regional housing needs. However,
HCD’s final determination for SACOG used this analysis while the SCAG region was held to
a different and less reasonable standard.
Improved Vacancy Rate Comparison
HCD seemingly uses unrealistic comparison points to evaluate healthy market vacancy, which is
also an unreasonable application of the methodology and assumptions described in statute. While
SB 828 specifies a vacancy rate for a healthy rental housing market as no less than 5 percent,
healthy market vacancy rates for for-sale housing are not specified. HCD’s practice is to compare
actual, ACS vacancy rates for the region versus a 5 percent total vacancy rate (i.e. owner and renter
markets combined).
During the consultation process, SCAG discussed this matter with HCD staff and provided several
points of comparison including historical data, planning standards, and comparisons with other
regions. In addition, SCAG staff illustrated that given tenure shares in the SCAG region, HCD’s
suggestion of a 5 percent total vacancy rate is mathematically equivalent to an 8 percent rental
market vacancy rate plus a 2.25 percent for-sale housing vacancy rate. However, in major
metropolitan regions, vacancy rates this high are rarely experienced outside of severe economic
recessions such as the recent, housing market-driven Great Recession. Given the region’s current
housing shortage, the high volume of vacant units envisioned in HCD’s planning target would be
rapidly absorbed, making it an unrealistic standard.
Housing Element Update Advisory Committee - October 21, 2020
Item No. V(b) - Attachment 2
Orange County Mayor's Letter to the Southern California Council of Governments (SCAG)
SCAG staff’s original suggestion of 5 percent rental vacancy and 1.5 percent for-sale vacancy
(resulting in a 3.17 percent total vacancy rate based on current tenure shares) is in fact higher than
the observed rate in the comparable regions defined above. It is also above Federal Housing
Authority standards for regions experiencing slow or moderate population growth. It is also above
the very liberal standard of 6 percent for for-rent housing and 2 percent for for-sale housing
suggested by the California Office of Planning and Research (equivalent to 3.90 percent total
vacancy based on SCAG tenure shares) which would also be a more reasonable application of the
methodology.1
Additional Considerations
In addition to the three key points above, SCAG’s proposed alternative includes several other
corrections to technical shortcomings in HCD’s analysis of regional housing needs.
1. HCD’s evaluation of replacement need is based on an arbitrary internal standard of 0.5 percent
to 5.0 percent of total housing units. 2010-2019 demolition data provided by DOF suggest that
over an 8.25-year period, it is reasonable to expect that 0.14 percent of the region’s total
housing units will be demolished, but not replaced. This would form the basis of a more
reasonable housing needs determination, as DOF’s survey represents the most comprehensive
and robust data available.
2. Anticipated household growth on tribal land was not excluded from the regional determination
as indicated in the consultation package and follow-up communications. Tribal entities within
the SCAG region have repeatedly requested that this estimate be excluded from the RHNA
process entirely since as sovereign nations, state law does not apply. SCAG’s proposed
approach is to subtract estimates of household growth on tribal land from the regional
determination and ensure that these figures are also excluded from local jurisdictions’ annual
progress reports (APRs) of new unit construction to HCD during the 6th cycle.
3. A refinement to the adjustment for cost burden would yield a more reasonable determination
of regional housing needs. SCAG has repeatedly emphasized the shortcomings of and overlap
across various ACS-based measures of housing need. Furthermore, the relationship between
new unit construction and cost burden is poorly understood (i.e., what will be the impact of
new units on cost, and by extension, cost-burden). Nonetheless, SCAG recognizes that the
region’s cost burden exceeds that of comparable regions and proposes one modification to
HCD’s methodology, which currently considers cost burden separately by lower and higher
income categories.
While housing security is dependent on income, it is also heavily dependent on tenure. While
spending above 30 percent of gross income on housing for renters can reflect true housing
insecurity, spending above this threshold for owners is substantially less problematic. This is
particularly true for higher income homeowners, who generally benefit from housing shortages
as it results in home value appreciation. Thus, a more reasonable application of cost burden
1 See Nelson, AC. (2004), Planner’s Estimating Guide Projecting Land-Use and Facility Needs. Planners Press,
American Planning Association, Chicago. P. 25.
Housing Element Update Advisory Committee - October 21, 2020
Item No. V(b) - Attachment 2
Orange County Mayor's Letter to the Southern California Council of Governments (SCAG)
statistics would exclude cost-burden experienced by moderate and above-moderate owner
households and instead make an adjustment based on three of the four income and tenure
combinations: lower-income renters, higher-income renters, and lower-income owners.
4. From our review, HCD’s data and use of data is not current. In large metropolitan regions,
there is no reasonable basis for using 5-year ACS data, which reflects average conditions from
2013 to 2017. For cost-burden adjustments, HCD relies on 2011-2015 CHAS data. By the
beginning of the 6th cycle of RHNA, some of the social conditions upon which the
determination is based will be eight years old.
During the consultation process, SCAG staff provided HCD with Excel-version data of all
inputs needed to replicate their methodology using ACS 2017 1-year data (the most recent
available); however, this was not used. The Census bureau is scheduled to release ACS 2018
1-year data on September 26, 2019. SCAG staff would support replicating the same analysis,
but substituting 2018 data when it becomes available in order to ensure the most accurate
estimates in planning for the region’s future.
Finally, given that the manner and order in which modifications are made affects the total housing
need, the attachments demonstrate two alternatives with varying interpretations of three of the
above points (see boldface, red text in attachments):
- Vacancy rate comparison – SCAG’s originally proposed values versus an alternative which
emerged from the consultation process
- Replacement need – DOF survey value versus HCD’s current practice
- Cost burden measure – whether or not to include higher-income homeowners in this
adjustment
We appreciate your careful consideration of this objection. RHNA is a complex process and we
recognize the difficult positions that both SCAG and HCD are in but are hopeful that our agencies
can reach a reasonable conclusion with respect to the regional need determination. Please contact
me if you have questions. I look forward to continuing our close partnership to address the housing
crisis in our state.
Sincerely,
Kome Ajise
Executive Director

Cost Burden Adjustment: A cost-burden adjustment is applied to the projected need by comparing the difference in cost-burden by income and
tenure group for the region to the cost-burden by income and tenure group for comparable regions. Data are from 2017 1-year ACS and the ACS
$50,000/year household income threshold is used to distinguish between lower and higher income groups. The lower income RHNA is increased by
the percent difference between the region and the comparison region cost burden rate for households earning approximately 80% of area median
income and below (88.89%-84.39%=4.51% for renters and 27.33%-20.97%=6.36% for owners), then this difference is applied to very low- and low-
income RHNA proportionate to the share of the population these groups currently represent (Very Low=63% of lower, Low=37% of lower). The
higher income RHNA is increased by the percent difference between the region and the comparison region cost burden rate (67.15%-65.53%=1.62%
for renters and 23.78%-17.06%=6.72% for owners) for households earning above 80% Area Median Income, then this difference is applied to
moderate and above moderate income RHNA proportionate to the share of the population these groups currently represent (Moderate=29% of
higher, Above Moderate=71% of higher). SCAG's analysis of the cost-burden measure suggests that it may be less appropriate to apply for
higher-income owners and it may be excluded from the adjustment.
Occupied Units: Reflects DOF's estimate of occupied units at the start of the projection period (June 30, 2021).
Projection period: Gov. Code 65588(f) specifies RHNA projection period start is December 31 or June 30, whichever date most closely precedes end
of previous RHNA projection period end date. RHNA projection period end date is set to align with planning period end date. The planning period
end date is eight years following the Housing Element due date, which is 18 months following the Regional Transportation Plan adoption rounded to
the 15th or end of the month.
Population, Group Quarters, Household Population, & Projected Households: Pursuant to Government Code Section 65584.01, projections were
extrapolated from SCAG's Regional Transportation Plan projections. Population reflects total persons. Group Quarter Population reflects persons in
a dormitory, group home, institution, military, etc. that do not require residential housing. Household Population reflects persons requiring residential
housing. Projected Households reflect the propensity of persons, by age-groups, to form households at different rates based on Census trends.
Vacancy Adjustment: Pursuant to Government Code 65584.01, a 5% minimum is considered to be healthy market vacancy in the for-rent housing
market. Vacancy rates in the for-sale market are unspecified in statute. SCAG's analysis of vacancy rates suggests a healthy market standard
of 5% for fore-rent housing and 1.5% for for-sale housing. After extensive consultation with HCD, a review of historical trends, regional
and national comparison, and various planning standards, a more liberal vacancy standard of 6% for for-rent housing and 2% for for-sale
housing may also be supported by this analysis. These standards are compared against ACS 2017 1-year data based on the renter/owner share in
the SCAG region.
Overcrowding Adjustment: In regions where overcrowding is greater than the Comparable Region Rate, an adjustment is applied based on the
amount the region's overcrowding rate (9.82%) exceeds the Comparable Region Rate (5.20%). Data is from 2017 1-year ACS.
Replacement Adjustment: A replacement adjustment is applied based on the current 10-year average % of demolitions according to local government
annual reports to Department of Finance. While these data suggest an adjustment of 0.14% is most appropriate, SCAG recognizes that
HCD's internal practice is to use an adjustment factor of 0.5%.

Dear Executive Director Ajise,
RE: Final Regional Housing Need Assessment
The California Department of Housing and Community Development (HCD) has received and
reviewed your objection to the Southern California Association of Governments (SCAG)’s
Regional Housing Needs Assessment (RHNA) provided on August 22, 2019. Pursuant to
Government Code (Gov. Code) section 65584.01(c)(3), HCD is reporting the results of its
review and consideration, along with a final written determination of SCAG’s RHNA and
explanation of methodology and inputs.
As a reminder, there are several reasons for the increase in SCAG’s 6th cycle Regional Housing
Needs Assessment (RHNA) as compared to the 5th cycle. First, as allowed under Gov. Code
65584.01(b)(2), the 6th cycle RHNA applied housing need adjustment factors to the region’s
total projected households, thus capturing existing and projected need. Second, overcrowding
and cost burden adjustments were added by statute between 5th and 6th cycle; increasing RHNA
in regions where incidents of these housing need indicators were especially high. SCAG’s
overcrowding rate is 10.11%, 6.76% higher than the national average. SCAG’s cost burden rate
is 69.88% for lower income households, and 18.65% for higher income households, 10.88%
and 8.70% higher than the national average respectively. Third, the 5th cycle RHNA for the
SCAG region was impacted by the recession and was significantly lower than SCAG’s 4th cycle
RHNA.
This RHNA methodology establishes the minimum number of homes needed to house the
region’s anticipated growth and brings these housing need indicators more in line with other
communities, but does not solve for these housing needs. Further, RHNA is ultimately a
requirement that the region zone sufficiently in order for these homes to have the potential to be
built, but it is not a requirement or guarantee that these homes will be built. In this sense, the
RHNA assigned by HCD is already a product of moderation and compromise; a minimum, not a
maximum amount of planning needed for the SCAG region.
For these reasons HCD has not altered its RHNA approach based on SCAG’s objection.
However, the cost burden data input has been updated following SCAG’s objection due to the
availability of more recent data. Attachment 1 displays the minimum RHNA of 1,341,827 total
homes among four income categories for SCAG to distribute among its local governments.
Attachment 2 explains the methodology applied pursuant to Gov. Code section 65584.01.

The following briefly responds to each of the points raised in SCAG’s objection:
Use of SCAG’s Population Forecast
SCAG’s overall population estimates for the end of the projection period exceed Department of
Finance’s (DOF) population projections by 1.32%, however the SCAG household projection
derived from this population forecast is 1.96% lower than DOF’s household projection. This is a
result of SCAG’s population forecast containing 3,812,391 under 15-year old persons,
compared to DOF’s population projection containing 3,292,955 under 15-year old persons;
519,436 more persons within the SCAG forecast that are anticipated to form no households. In
this one age category, DOF’s projections differ from SCAG’s forecast by 15.8%.
Due to a greater than 1.5% difference in the population forecast assessment of under 15-year
olds (15.8%), and the resulting difference in projected households (1.96%), HCD maintains the
use of the DOF projection in the final RHNA.
Use of Comparable Regions
While the statute allows for the council of government to determine and provide the comparable
regions to be used for benchmarking against overcrowding and cost burden, Gov. Code
65584.01(b)(2) also allows HCD to “accept or reject information provided by the council of
governments or modify its own assumptions or methodology based on this information.”
Ultimately, HCD did not find the proposed comparable regions an effective benchmark to
compare SCAG’s overcrowding and cost burden metrics to. HCD used the national average as
the comparison benchmark, which had been used previously throughout 6th cycle prior to the
addition of comparable region language into the statute starting in January 2019. As the housing
crisis is experienced nationally, even the national average does not express an ideal
overcrowding or cost burden rate; we can do more to reduce and eliminate these worst-case
housing needs.
Vacancy Rate
No changes have been made to the vacancy rate standard used by HCD for the 6th cycle RHNA
methodology.
Replacement Need
No changes have been made to the replacement need minimum of adjustment .5%. This
accounts for replacement homes needed to account for homes potentially lost during the
projection period.
Household Growth Anticipated on Tribal Lands
No changes have been made to reduce the number of households planned in the SCAG region
by the amount of household growth expected on tribal lands. The region should plan for these
homes outside of tribal lands.
Overlap between Overcrowding and Cost Burden
No changes have been made to overcrowding and cost burden methodology. Both factors are
allowed statutorily, and both are applied conservatively in the current methodology.

Data Sources
No changes have been made to the data sources used in the methodology. 5-year American
Community Survey data allows for lower margin of error rates and is the preferred data source
used throughout this cycle. With regard to cost burden rates, HCD continues to use the
Comprehensive Housing Affordability Strategy, known as CHAS data. These are custom
tabulations of American Community Survey requested by the U.S. Department of Housing and
Urban Development. These customs tabulations display cost burden by income categories,
such as lower income, households at or below 80% area median income; rather than a specific
income, such as $50,000. The definition of lower income shifts by region and CHAS data
accommodates for that shift. The 2013-2016 CHAS data became available August 9, 2019,
shortly prior to the issuance of SCAG’s RHNA determination so that data is now used in this
RHNA.
Next Steps
As you know, SCAG is responsible for adopting a RHNA allocation methodology for the
projection period beginning June 30, 2021 and ending October 15, 2029. Pursuant to Gov.
Code section 65584(d), SCAG’s RHNA allocation methodology must further the following
objectives:
(1) Increasing the housing supply and the mix of housing types, tenure, and affordability in all cities and
counties within the region in an equitable manner, which shall result in each jurisdiction receiving an
allocation of units for low- and very-low income households.
(2) Promoting infill development and socioeconomic equity, the protection of environmental and
agricultural resources, the encouragement of efficient development patterns, and the achievement of the
region’s greenhouse gas reductions targets provided by the State Air Resources Board pursuant to
Section 65080.
(3) Promoting an improved intraregional relationship between jobs and housing, including an improved
balance between the number of low-wage jobs and the number of housing units affordable to low-wage
workers in each jurisdiction.
(4) Allocating a lower proportion of housing need to an income category when a jurisdiction already has a
disproportionately high share of households in that income category, as compared to the countywide
distribution of households in that category from the most recent American Community Survey.
(5) Affirmatively furthering fair housing.
Pursuant to Gov. Code section 65584.04(e), to the extent data is available, SCAG shall include
the factors listed in Gov. Code section 65584.04(e)(1-12) to develop its RHNA allocation
methodology. Pursuant to Gov. Code section 65584.04(f), SCAG must explain in writing how
each of these factors was incorporated into the RHNA allocation methodology and how the
methodology furthers the statutory objectives described above. Pursuant to Gov. Code section
65584.04(h), SCAG must consult with HCD and submit its draft allocation methodology to HCD
for review.

Explanation and Data Sources
1-4. Population, Group Quarters, Household Population, & Projected Households: Pursuant to
Government Code Section 65584.01, projections were extrapolated from Department of
Finance (DOF) projections. Population reflects total persons. Group Quarter Population
reflects persons in a dormitory, group home, institution, military, etc. that do not require
residential housing. Household Population reflects persons requiring residential housing.
Projected Households reflect the propensity of persons, by age-groups, to form households
at different rates based on Census trends.
5. Vacancy Adjustment: HCD applies a vacancy adjustment based on the difference between a
standard 5% vacancy rate and the region’s current "for rent and sale" vacancy percentage to
provide healthy market vacancies to facilitate housing availability and resident mobility. The
adjustment is the difference between standard 5% and region’s current vacancy rate (2.37%)
based on the 2013-2017 5-year American Community Survey (ACS) data. For SCAG that
difference is 2.63%.
6. Overcrowding Adjustment: In region’s where overcrowding is greater than the U.S
overcrowding rate of 3.35%, HCD applies an adjustment based on the amount the region’s
overcrowding rate (10.11%) exceeds the U.S. overcrowding rate (3.35%) based on the 2013-
2017 5-year ACS data. For SCAG that difference is 6.76%.

7. Replacement Adjustment: HCD applies a replacement adjustment between .5% & 5% to total
housing stock based on the current 10-year average of demolitions in the region’s local
Housing Element Update Advisory Committee - October 21, 2020

government annual reports to Department of Finance (DOF). For SCAG, the 10-year average
is .14%, and SCAG’s consultation package provided additional data on this input indicating it
may be closer to .41%; in either data source the estimate is below the minimum replacement
adjustment so the minimum adjustment factor of .5% is applied.
8. Occupied Units: Reflects DOF's estimate of occupied units at the start of the projection period
(June 30, 2021).
9. Cost Burden Adjustment: HCD applies an adjustment to the projected need by comparing the
difference in cost-burden by income group for the region to the cost-burden by income group
for the nation. The very-low and low income RHNA is increased by the percent difference
(69.88%-59.01%=10.88%) between the region and the national average cost burden rate for
households earning 80% of area median income and below, then this difference is applied to
very low- and low-income RHNA proportionate to the share of the population these groups
currently represent. The moderate and above-moderate income RHNA is increased by the
percent difference (18.65%-9.94%=8.70%) between the region and the national average cost
burden rate for households earning above 80% Area Median Income, then this difference is
applied to moderate and above moderate income RHNA proportionate to the share of the
population these groups currently represent. Data is from 2013-2016 Comprehensive
Housing Affordability Strategy (CHAS).

Do the Math: The state has ordered more than
350 cities to prepare the way for more than
2 million homes by 2030.
But what if the math is wrong?
Senate Bill 828, co-sponsored by the Bay Area Council and Silicon Valley
Leadership Group, and authored by state Sen. Scott Wiener in 2018, has
inadvertently doubled the “Regional Housing Needs Assessment” in
California.
Use of an incorrect vacancy rate and double counting, inspired by SB-828, caused the state’s
Department of Housing and Community Development (HCD) to exaggerate by more than
900,000 the units needed in SoCal, the Bay Area and the Sacramento area.
The state’s approach to determining the housing need must be defensible and reproducible if
cities are to be held accountable. Inaccuracies on this scale mask the fact that cities and
counties are surpassing the state’s market-rate housing targets, but falling far short in
meeting affordable housing targets. The innacuracies obscure the real problem and the
associated solution to the housing crisis—the funding of affordable housing.

Every five to eight years the Department of Housing and Community Development (HCD) supervises and publishes the
results of a process referred to as the Regional Housing Needs Assessment (RHNA). Four regional planning agencies
cover the 21 most urban counties and account for 80% of California’s housing. All four regions saw a significant jump
in the state’s assessment of their housing need for the years 2021 to 2030.
Double counting (not surprisingly) doubled the assessed housing need for the four major planning regions.

California plans for its housing needs in “cycles.” The four regions are on cycles that last roughly eight years with
staggered start dates. In the 2021–2030 housing cycle, errors introduced by language in SB-828 nearly equal the entire
1.15M units of new housing required during the 2013–2022 “cycle.” As illustrated, Southern California and the Bay Area
are the most impacted by the state’s methodology errors.
The double count, an unintended consequence of Senate Bill 828, has exaggerated the housing
need by more than 900,000 units in the four regions below.Number of Housing Units(1,341,827)

Senate Bill 828 was drafted absent a detailed understanding of the Department of Finance’s methodology for
developing household forecasts, and absent an understanding of the difference between rental and
home-owner vacancies. These misunderstandings have unwittingly ensured a series of double counts.
State’s erroneous
benchmark of 5%Annual Homeowner Vacancy Rates for the United States and Regions: 1968º2019
Typical
benchmark
is 1.5%
3
1. SB-828 wrongly assumed ‘existing
housing need’ was not evaluated as part
of California’s previous Regional Housing
Need Assessments, or RHNA. There was
an assumption that only future need had
been taken into account in past assess-
ments. (In fact, as detailed in The Reality
section, the state’s existing housing need
was fully evaluated in previous RHNA
assessment cycles).
2. SB-828 wrongly assumed a 5%
vacancy rate in owner-occupied
housing is healthy (as explained in the
column on the right, 5% vacancy in
owner-occupied homes is never desir-
able, and contradicts Government Code
65584.01(b)(1)(E) which specifies that a
5% vacancy rate applies only to the
rental housing market).
3. SB-828 wrongly assumed overcrowding and
cost-burdening had not been considered in
Department of Finance projections of housing
need. The bill sought to redress what it mistaken-
ly thought had been left out by requiring regional
planning agencies to report overcrowding and
cost-burdening data to the Dept. of Housing and
Community Development (as explained in the
right column).
SB-828 MISTAKENLY ASSUMED:THE REALITY IS:
1. Existing housing need has long been incorporated in California’s planning cycles. It has been evaluated by
comparing existing vacancy rates with widely accepted benchmarks for healthy market vacancies (rental
and owner-occupied). The difference between actual and benchmark is the measure of housing need/surplus
in a housing market. Confusion about the inclusion of “existing need” may have arisen because vacancy rates
at the time of the last assessment of housing need (”the 5th cycle”) were unusually high (higher than the
healthy benchmarks) due to the foreclosure crisis of 2007–2010, and in fact, the vacancy rates suggested a
surplus of housing. So, in the 5th cycle the vacancy adjustment had the effect of lowering the total housing
need. Correctly seeing the foreclosure crisis as temporary, the state Department of Finance did not apply the
full weight of the surplus, but instead assumed a percentage of the vacant housing would absorbed by the
time the 5th cycle began. The adjustment appears in the 5th cycle determinations, not as ‘Existing Housing
Need’ but rather as “Adjustment for Absorption of Existing Excess Vacant Units.”
2. While 5% is a healthy
benchmark for rental
vacancies, it is unhealthy
for owner-occupied
housing (which typically
represents half of existing
housing). Homeowner
vacancy in the U.S. has
hovered around 1.5% since
the ‘70s, briefly reaching
3% during the foreclosure
crisis. However, 5% is well
outside any healthy norm,
and thus does not appear
on the Census chart (to the
right) showing Annual
Homeowner Vacancy
Rates for the United States
and Regions: 1968–2019.
3. Unknown to the authors of SB-828, the Department of Finance (DOF) has for years factored overcrowding
and cost-burdening into their household projections. These projections are developed by multiplying
estimated population by the headship rate (the proportion of the population who will be head of a household).
The Department of Finance (DOF) in conjunction with the Department of Housing and Community
Development (HCD) has documented its deliberate decision to use higher headship rates to reflect optimal
conditions and intentionally “alleviate the burdens of high housing cost and overcrowding.” Unfortunately,
SB-828 has caused the state to double count these important numbers.

1. Incorrect use of a 5% benchmark vacancy rate for owner-occupied housing.
The vacancy rate was incorrectly used for both existing and projected owner-occupied households.
2. Current vacancies were assumed to exist in household projections.
This error is unrelated to SB-828, but is an accounting error introduced by HCD methodology.
3. Overcrowding and cost-burdening were double counted.**
In addition to the household projection methodology outlined by the Department of Finance
(shown to account for overcrowding and cost-burdening), the matter is also mentioned in
meeting notes available on the Association of Bay Area Government’s (ABAG) website.***
Quote from ABAG’s Housing Methodology Committee Agenda Packet for the 4th RHNA
Cycle, July 2006
“There was also a lot of discussion about the headship rates used by HCD/DOF. Several
people commented that headship rates in the Bay Area are generally lower than the State’s
estimates because the region’s high housing costs limit household formation. In response,
Mr. Fassinger noted that HCD uses these higher headship rates because the RHNA process
is intended to alleviate the burdens of high housing cost and overcrowding.”
Despite this, overcrowding and cost-burdening were counted a second time as adjustment
factors required by SB-828.

The state has shown, with decades of data, that it cannot dictate to the market. The market is going to take care of
itself. The state’s responsibility is to take care of those left behind in the market’s wake. Based on housing permit
progress reports published by the Dept. of Housing and Community Development in July 2020, cities and counties in
the four most populous regions continue to strongly outperform on the state’s assigned market-rate housing targets,
but fail to achieve even 20% of their low-income housing target. In the Bay Area where permit records have been kept
since 1997, there is evidence that this housing permit imbalance has propagated through decades of housing cycles.
The state’s exaggerated targets unfortunately mask the real story: Decades of overachieving in
market-rate housing has not reduced housing costs for lower income households.

Cities are charged by the state to build one market-rate home for every one affordable home. But state laws, such as the density bonus law, incentivize
developers to build market-rate units at a far higher rate than affordable units. As a result, California has been building four market-rate units for every
one affordable unit for decades. And with the near-collapse of legislative funding for low-income housing in 2011, that ratio has grown to seven to eight
market-rate units to each affordable unit. Yet we need one-to-one. This worsening situation can’t be fixed by zoning or incentives which are the focus of
many recent housing bills and only reinforce or worsen the ever-higher market-rate housing ratios. From the data it appears that the shortage of housing
resulted not from a failure by cities to issue housing permits, but rather a failure by the state to fund and support affordable housing. Future legislative
efforts should take note.

Finally, since penalties are incurred for failing to reach state targets for housing permits,
the methodology for developing these numbers must be transparent, rigorous and defensible.
Non-performance in an income category triggers a streamlined approval process per Senate Bill 35 (2017). These
exaggerated 6th cycle targets will make it impossible for cities and counties to attain even their market-rate targets,
ensuring market-rate housing will qualify for incentives and bonuses meant for low income housing. Yet again
low-income housing will lose out. The state needs to correct the errors in the latest housing assessement, and settle
on a consistent, defensible approach going forward.

formation rate determine the number of households needed to comfortably house that population*. The DOF also supply the HCD
with the number of existing households at the start of the cycle. The HCD adds to the base number of additional households
needed, factoring in vacancies for a healthy market, and adding a replacement adjustment (also supplied by the DOF)**.
* Households represent occupied housing units. The number of housing units is always higher as at any given time than the number of households because some housing will be vacant or
unutilized. The DOF is responsible for the base projection because they manage population projections for the state, and determine those by analyzing births, deaths and net migration.

Instead of the typical 1.5% benchmark for owner-occupied housing, they used a 5% vacancy rate usually reserved for

Two new factors were introduced into the 6th assessment — overcrowding and cost burdening. These factors had
already been rolled into the DOF’s household projections. The DOF explicitly recognized that regional household
formation rates might be depressed (a symptom of overcrowding and cost-burdening) because of the affordable
housing crisis. The household formation rate used by the DOF is higher than the actual rate experienced. As such it
generates a higher housing target meant to relieve overcrowding and cost-burdening.

should not be allowed to solely dominate the projection,

Lastly, the Dept. of Housing and Community Development double counted by adding two new factors
that had already been factored into household forecasts made by the Dept. of Finance (DOF).
* In addition to double counting, HCD incorrectly calculated the overcrowding factor. They assumed that for every house that was overcrowded another house would be required to relieve
overcrowding. The more accurate analysis would be to assess the number of extra people to be housed and divide by the average household size.
** HCD only applied cost-burdening adjustments to future households not existing households. It is unclear why cost-burdening would only be considered an issue for future households, as
the data is for current households.
