SUBJECT: ITEM 4A – RENTAL HOUSING REGISTRY STUDY SESSION
Staff received the following questions regarding a potential Rental Housing Registry. The
questions are below with staff’s response shown in italics:
1) What percentage of SLO residents are renters? How has this percentage
changed since 2016?
According to the U.S. Census American Community Survey, in 2024, 59.7% of
households in the City were renters. This is down approximately 4 percent from
2016, when 63.5% of households in the City were renters. The Census data is
based on estimates and has a 1-2 percent margin of error.
2) What are the dollar amounts of rental rates in the City since 2016? What is
the source of this information?
Below are the median rents in the City from 2016-2024 according to the U.S.
Census American Community Survey. These figures are estimates based on self-
reported information from Census respondents, not a comprehensive study of all
rental units in the City. Additionally, the figures are irrespective of bedroom count
or size of units. The Census Bureau claims a 2-3% margin of error for this data.
U.S. Census Median Rents – 2016-2024
2016: $1,323/month
2017: $1,403/month
2018: $1,461/month
2019: $1,575/month
2020: $1,611/month
2021: $1,718/month
2022: $1,850/month
2023: $1,906/month
2024: $1,965/month

Staff also has access to real-time rental market data from Zillow, which aggregates
comprehensive data from all listings on its site as well as the MLS, public tax
records, and other Internet data to establish a real-time average rent. The average
rent has gone up since staff initially published the report and currently shows a
$3,748 per month average rent in the City. This discrepancy is likely due to the
increase in the amount and potentially a change in the type of units (for example,
more large single-family homes with multiple bedrooms would make the number
higher than smaller apartment units) listed on the market since staff pulled the
number that is included in the staff report. The Zillow average rent is a real-time
number that is primarily driven by shifting market conditions and changes
frequently over time.
The discrepancies between the Zillow data and Census data highlights the
challenge in the City to have a comprehensive understanding of rental rates at any
given time. Both sources do not directly collect verifiable information from property
owners at regular time intervals.
3) Could the existing Business License database and existing enforcement
tools be retooled to fix the City’s lack of verifiable information, for instance
lack of data about the number of units and property characteristics,
condition, ownership contact information, turn over, code violations, city
permitting data for each unit, noise violations, eviction rates and/or rental
rates and other charges of rental properties?
The existing business license database can be modified to collect additional
information and data points through the current self-reporting process. With that in
mind, the business license database cannot be modified to verifiably collect and
analyze this information on all rental housing units in the City without additional
software, staffing, and regulations to establish an enforcement process. The
resources required to complete this effort are equivalent to that of a mandatory
rental registry, without the guarantee of cost recovery through fee revenue as well
as tangible data insights that a mandatory rental registry could provide.
4) On page 12 of the report, it states that rental registry software costs about
$10-50K including start-up costs and yearly subscriptions. This is a big
range, but generally, is it true that after set-up, the annual fee is a less than
the start-up year (or two…however long “start-up” takes)?
The range of software costs comes from preliminary conversations with rental
registry software providers. All providers charge a fixed annual fee for program
operations. Some software providers do charge additional fees during the first year
of implementation to cover start-up costs, whereas others do not.

5) Page 14 states that we receive about $3 million annually from business
taxes, inclusive of those that are residential rental businesses. It also states
that 2619 of the businesses currently registered in this system are residential
rental businesses. While I understand that these 2,619 businesses do not
necessarily represent 2,619 units, with a total estimated number of 14,970
rental units in the city, it appears we have very few residential rental
businesses registered in our current system. This seems to indicate that
there is a significant number of rental businesses that are out of compliance
with our existing ordinances. Do we have any estimates of the amount of
business permit and tax revenue the city could generate from bringing more
rental businesses into compliance? Is this one reason for pursuing a rental
registry?
It is difficult to estimate the potential for additional business tax revenue from
currently non-compliant businesses based on an estimated number of units out of
compliance alone. The amount of business tax that the City collects is based on
the gross receipts earned by each business. Business tax is calculated at a rate
of $0.50 per thousand dollars of gross receipts, or 0.05%. In order to be able to
calculate the tax that the City is not currently collecting, staff would need to
have information related to the rents charged for the rentals that are currently out
of compliance. Based on gross receipts provided by currently licensed residential
rentals, the average gross receipts for residential rental businesses
is approximately $100,000 a year (generating $50 of business tax).
6) On page 18 of the packet, staff lists a number of 2025-27 work plan items that
might need to be re-prioritized if the council gave direction in the current
financial plan to pursue a rental registry. It also states that many of these
items cannot be postponed because they are associated with state-
mandated activities. Can you please clarify which items COULD be
postponed, because they are NOT associated with state mandates?
Staff listed 10 work plan items that would need to be re-evaluated or postponed.
Of the 10 items, 5 are mandated by state law and cannot be postponed. The
following 5 work plan items are not associated with state law requirements:
• 1.a. Organize a focus group to explore barriers to residential infill
development—including specific discussions about the Downtown Core—and
produce a memo to Council to help guide updates to the Zoning Regulations.
• 2.a. Conduct an educational forum and improve the implementation of Below
Market Rate (BMR) best practices to market and streamline the purchase and
rental process for BMR units.
• 3.d. Create a strategic plan for the safe housing program, and conduct outreach
and engagement with a focus on both tenants and landlords.
• 4.b. Conduct a study session with Council on Code Enforcement priorities
related to safe/livable neighborhoods and receive feedback on priorities.
Discuss potential updates to property maintenance standards.

• 4.d. Create a project plan and standard operating procedures for Community
Development enforcement of zoning code regulations pertaining to Greek
houses. Consider potential updates to zoning code to facilitate efficient
regulation of Greek houses.
In addition, it should be noted that the Housing Team (currently two staff
members, as the Principal Planner position is unfilled) of the Community
Development Department are also responsible for and spend a significant
amount of time on processing housing entitlements and building permits,
facilitating the Below Market Rate Housing Program, managing the City’s
Community Development Block Grant (CDBG) and Affordable Housing Fund
programs, preparing the General Plan Annual Report, collaborating with the
development community on housing project concepts, responding to
community inquiries regarding the City’s affordable housing programs, working
to ensure understanding and ongoing compliance with a continuing large
volume of new housing law legislation, and other work efforts which are not
directly supporting the City’s Major City Goal work programs.
7) What number and percentage of code violations in residential zones are
currently attributable to rental units? Further, how many of those involve
substandard, overcrowded or unsanitary conditions in single family and
duplex units in R1 and R2 zones?
Some of these numbers could be generated with additional time, however, the
analysis necessary to answer the specifics of this question cannot be completed
in time for this Agenda Correspondence. Our software system does not
differentiate between rental and owner-occupied units, and additional analysis with
GIS would be necessary to tie code enforcement cases to underlying land use
zoning and residential rental business licenses. In general, code enforcement
cases opened for rental units are designated as ‘Safe Housing’ cases. These are
not restricted to residentially zoned areas but are related to structures in which a
tenant is living, and city staff has inspected for substandard conditions. These
locations may be reported by the tenant, a third party or may have been discovered
through a larger scale investigation. Since January 2024, 101 Safe Housing cases
have been opened. This accounts for approximately 23% of all code enforcement
cases (excluding neighborhood wellness violations, e.g., noise, zoning and/or
general property maintenance standards violations, not necessarily implicating
habitability or safe occupancy concerns) during this time period.

8) From our previous study session in October 2025, we learned that about
15,306 units are likely exempt from the statewide TPA law. We don’t have
good data at the moment about how many of these are rental units, if I recall
correctly. However, because of the Costa-Hawkins Act, we can’t extend rent
stabilization to any units that might be rental units in this pool, correct? We
only have legal authority to add eviction protections to rental units within
this 15k units?
Under state law known as the Costa-Hawkins Act, the City cannot expand rent
stabilization protections to any units built after 1995, or any single-family units
regardless of date of construction. This means that the only rental units that could
be subject to a local rent control ordinance are multifamily rental units constructed
prior to 1995; these units are already subject to the state TPA. The City does not
have the ability to expand rent stabilization to housing types beyond those already
subject to the protections of the Tenant Protection Act. As for rent stabilization, the
City could impose a more restrictive cap on rent increases (e.g., 4% instead of the
maximum allowed under the TPA) but this would only apply to the types of units
already protected by the TPA.
9) What are the options for determining or estimating the number, location,
size/rooms, and rent for all rental units in the City, other than a rental
registry? For example, how much data can we get from third parties such as
Zillow and how accurate is it?
The data available regarding the City’s rental housing stock is limited to U.S.
Census data and data from private aggregators such as Zillow and CoStar. The
private data does collect information from a variety of public and private sources,
but is not verifiable. The private data, particularly the average rent, is influenced
by market forces. For example, the average rent according to Zillow at October’s
study session was $2,625 per month, whereas at the time of this report, the
average rent is $3,748 per month. This is likely due to the influx of rental listings
hitting the market on Zillow for the new year, which is significantly swaying the real-
time data. A rental registry would collect the actual monthly rent at a yearly interval
based on verifiable information collected from property owners, leading to an
accurate average rent statistic when compared to the currently available data.
10) Can the City require completion and submission of a rental inventory
checklist for tenants and landlords?
Through the creation of an ordinance requiring mandatory submission of
information with specific enforcement procedures, completion of a checklist could
be required.
