ORDINANCE NO. NS-XXXX entitled AN ORDINANCE OF THE CITY COUNCIL OF
THE CITY OF SANTA ANA PROHIBITING ANTI-COMPETITIVE AUTOMATED RENT
PRICE FIXING
GOVERNMENT CODE §84308 APPLIES: No
DISCUSSION
The use of algorithmic devices to set rental rates in the private rental market has
contributed to the nationwide housing affordability crisis. These tools utilize nonpublic
competitor data, including real time rents, lease renewals, and occupancy levels to
generate coordinated pricing recommendations that inflate rental rates beyond
competitive market levels. National analyses and federal lawsuits suggest that such tools
may contribute to double-digit rent increases, increased rates of eviction, and artificial
housing scarcity. The purpose of this ordinance is therefore to protect renters in the City
of Santa Ana (City) from artificially inflated rents and unfair rent-setting practices.
The City’s renters are subjected to the affordability pressures created by these algorithmic
devices. According to the U.S. Census Bureau’s 2023 5-Year American Community
Survey (ACS), the City has 79,691 occupied housing units, of which 44,151 are renter-
occupied households accounting for over 55% of the total occupied housing units.
Approximately 53% of these households are considered cost-burdened with housing
expenses exceeding 30% of overall household income. The City’s median household
income has not kept pace with the growth in rental housing costs, placing disproportionate
pressure on low-income and working-class families. The City’s review of current rental
market conditions, together with findings from federal investigations and national
research, indicates that algorithmic rent setting tools pose a risk to housing affordability
in Santa Ana. In a 2024 study by the White House, it was reported that renters nationally

spent an extra $3.8 billion in rent in 2023; Los Angeles renters in units managed with
algorithms paid an average of $408 more annually, compared to renters in units not
managed with algorithms.
Overview of Legislation Addressing Algorithmic Pricing and Antitrust
AB 325 Cartwright Act: Violations
Assembly Bill 325, enacted on October 6, 2025 and effective January 1, 2026, amends
the Cartwright Act to further expand the scope of conduct prohibited under California
antitrust law. The bill clarifies that the use of a “common pricing algorithm” may constitute
unlawful price fixing when used as part of a contract, combination in the form of a trust,
or conspiracy to restrain trade or commerce. AB 325 addresses concerns that pricing
software and algorithmic tools can function as mechanisms for coordinating prices, rental
rates, or supply levels. By amending the Cartwright Act, AB 325 clarifies that the use of
shared or common pricing algorithms may be treated as evidence of a concerted practice
when the effect of such use is to artificially influence prices in the real estate market. AB
325 does not impose an outright ban on pricing software, instead the bill operates
primarily as a clarification of liability standards within the existing antitrust law framework.
Enforcement of the Act continues to rely on state or local prosecutors or private parties
bringing antitrust actions.
Proposed bill - SB 384 Preventing Algorithmic Price Fixing Act
Senate Bill 384, the Preventing Algorithmic Price Fixing Act, would make it unlawful for a
person to sell, license, provide, or use a “price-setting algorithm” with the intent or
reasonable expectation that it will be used by two or more competitors in the same market,
when the person knows or should know that the algorithm relies on nonpublic data to
determine either: 1) the price or supply of a good or service, or 2) the rent or occupancy
level of rental property.
Unlike AB 325, SB 384 creates a standalone prohibition on a “price-setting algorithm”
when it is intended or can be reasonably expected to be used by two or more competitors
in the same market and processes nonpublic data. SB 384 would allow a user of such an
algorithm to claim an affirmative defense if they exercised specified reasonable due
diligence. It would also authorize the State Attorney General, as well as certain local
prosecutors, to bring civil actions for violations, including seeking civil penalties of up to
$1,000 per violation. As of February 2026, SB 384 has advanced through the Senate floor
and various committees; and is currently undergoing Second Committee Review.
Federal and State Antitrust Litigation
Antitrust lawsuits have been filed against third-party revenue management companies,
including RealPage, Inc. and Yardi Systems, Inc., as well as landlords who are using
alleged rent-fixing conspiracies. The lawsuits allege that these companies are enabling
unlawful rent-fixing. In August 2024, the United States Department of Justice (DOJ) filed
an antitrust lawsuit against RealPage accusing the company of unlawfully reducing
market competition and artificially raising rents. Eight state Attorneys General, including

California Attorney General Rob Bonta, joined the action. In January 2025, the DOJ
updated the lawsuit to include two additional Attorneys General and to identify landlords
as defendants. The case is still underway, though several defendants have already
settled with the Department of Justice and participating state attorneys general. Greystar,
one of the major defendants, agreed to pay $7 million to the DOJ and another $7 million
to the state attorneys general, and to discontinue its use of RealPage’s algorithmic pricing
tool. However, RealPage and several other landlords continue to litigate the matter, with
RealPage seeking dismissal of the claims and the remaining defendants also contesting
the lawsuit.
Proposed Santa Ana Ordinance Prohibiting Anti-Competitive Automated Rent
Price-Fixing
The proposed ordinance would prohibit the sale, licensing, provision, and use of certain
algorithmic rent-setting tools within the City. A citywide ban on providing or using an
“Algorithmic Device” that uses nonpublic competitor data to recommend rents and
occupancy levels for residential rental property in the City. The ordinance is limited in
scope to residential rental property and does not apply to pricing software that relies solely
on publicly available data, aggregate historical data, or tools used to comply with
affordable housing program requirements.
The proposed ordinance establishes a local prohibition on algorithmic devices that
facilitate coordinated rent-setting practices; the ordinance also establishes a tenant-
focused enforcement mechanism. A tenant affected by a violation of this ordinance may
seek injunctive relief, damages, or civil penalties up to $1,000 per violation, plus attorney’s
fees. Each residential unit and each month of continued use of algorithmic devices
constitutes a separate violation. These enforcement provisions are intended to provide
tenants with a direct and accessible remedy, independent of state or federal enforcement
actions.
The proposed ordinance is designed to operate alongside existing and proposed state
antitrust laws while providing greater protections to tenants by:
- defining a more limited scope (residential rental property within Santa Ana city
limits),
- providing direct enforcement abilities (tenants may seek relief via civil action),
and
- easing the burden of proof (tenants need to show that the landlord used an
algorithmic device and the device relied on nonpublic competitor data).
Existing state law does not expressly preempt local regulation of algorithmic rent-
setting practices. AB 325 clarifies the application of antitrust principles of algorithmic
pricing under the Cartwright Act, but does not establish an exclusive regulatory
framework. If SB 384 is enacted, the bill would supplement rather than displace
existing antitrust law.

ORDINANCE NO. NS-XXXX
AN ORDINANCE OF THE CITY COUNCIL OF THE CITY OF
SANTA ANA PROHIBITING ANTI-COMPETITIVE
AUTOMATED RENT PRICE-FIXING
THE CITY COUNCIL OF THE CITY OF SANTA ANA DOES ORDAIN AS
FOLLOWS:
Section 1. The City Council of Santa Ana hereby finds, determines, and declares
as follows:
A. The housing rent burden and poverty faced by many residents in the City of
Santa Ana (City) threatens the health, safety, and welfare to the City.
B. The City Council has provided relief to residents by enacting a Rent
Stabilization and Just Cause Eviction Ordinance, directing City staff to apply
for housing grants to lower the cost of living for residents and placing a priority
on assisting residents by providing information about issues that can negatively
affect their lives.
C. The high cost of living and housing shortage in the City have contributed to the
City’s unaffordability. According to an October 2025 Zillow report, a family must
earn $220,000 a year to afford a home mortgage in Santa Ana. According to
an October 22, 2025 Orange County Register article, the average rental rate
for a residential dwelling unit in the City is $2,293, approximately 40.6% higher
than the national median of $1,631.
D. According to the U.S. Census Bureau’s 2023 American Community Survey
(ACS), Santa Ana has approximately 79,691 occupied housing units, of which
44,151 are renter-occupied households, accounting for over 55% of the total
occupied housing units in Santa Ana. Approximately 53% of renter households
are considered cost-burdened, with housing expenses exceeding 30% of
household income. The City’s median household income has not kept pace
with the growth in rental housing costs, placing disproportionate pressure on
low-income and working-class families.
E. Landlords’ use of algorithmic devices, which perform calculations of nonpublic
competitor data concerning rental rates, occupancy levels, and other
information, to set rental rates and occupancy levels has resulted in inflated
rental rates an unfair rent increases and contributed to the City’s unaffordability
for families.
F. A 2024 study by the White House reported that renters nationally spent an extra
$3.8 billion in rent in 2023 because of pricing algorithms, and that Los Angeles
renters in units managed with algorithms paid an average of $408 more than

renters in units that were not managed with algorithms. The average monthly
cost for Santa Ana is unavailable.
G. In response to the use of algorithmic devices to set rental rates and occupancy
levels, in August 2024, the United States Department of Justice (DOJ) filed a
lawsuit against RealPage, Inc. Eight Attorneys General, including California
Attorney General Rob Bonta, joined the DOJ’s lawsuit. The DOJ amended its
lawsuit in January 2025 to add two Attorneys General and name landlords and
defendants.This lawsuit was settled in November 2025 and per the DOJ, “the
proposed settlement would help restore free market competition in rental
markets for millions of American renters.” Per the settlement, RealPage did not
admit any wrongdoing or liability, RealPage must not use their competitors’
non-public information, and an independent monitor will ensure compliance for
seven (7) years. City renters cannot hope that RealPage does not violate the
settlement nor that RealPage will be caught by the independent monitor.
H. RealPage filed a federal lawsuit against the City of Berkeley in April 2025
challenging their ordinance that bans landlords from using algorithmic revenue
management software for setting rental rates. While the litigation is pending,
and as RealPage will be monitored City renters cannot wait for this lawsuit to
run its course. The Council wishes to provide immediate relief to City renters
by prohibiting the sale, licensing, and use of algorithmic devices that use or
incorporate nonpublic competitor data to advise a landlord on, or recommend
to a landlord, rental rates or occupancy levels that may be achieved for
residential real property in the City.
Section 2. The recitals and statements of fact set forth in the preamble to this
ordinance are true and correct, constitute a substantive part of the ordinance, and are
incorporated herein by reference.

reasonably foreseeable indirect physical change to the environment, as there is no
possibility it will have a significant effect on the environment and it is not a “project” as
defined in section 15378 of the State CEQA Guidelines. Furthermore, the proposed
Ordinance falls within the “common sense” CEQA exemption set forth in CEQA
