TL;DR — Key Takeaways
- California rent control by city is not a separate system from state law. It is a third layer sitting between the Costa-Hawkins Rental Housing Act, which limits what a city may control, and the Tenant Protection Act at Civil Code sections 1947.12 and 1946.2, which sets a statewide baseline.
- Costa-Hawkins, at Civil Code section 1954.50 and following, is the ceiling on local power. Section 1954.52(a) lets an owner set the initial and all subsequent rental rates for a unit with a certificate of occupancy issued after February 1, 1995, and for a unit alienable separate from the title to any other dwelling unit – which is what removes most single-family homes and condominiums from local rent control.
- Section 1954.53 is vacancy decontrol. An owner may generally set the initial rental rate for a new tenancy even in a rent-controlled jurisdiction, subject to exceptions where the prior tenancy ended by the owner’s own notice or by a noticed change in terms.
- On the state side, section 1947.12(d)(3) exempts from the state cap any housing already subject to a stricter local limit, and section 1946.2(i) provides that a property is never subject to both the state just cause rule and a local just cause ordinance. One set governs, not both.
- Registration, filing, petition, and disclosure duties are the practical difference between a rent-controlled and a non-rent-controlled property, and they come from the ordinance rather than from state law.
The Direct Answer
California rent control by city operates inside limits state law sets. Costa-Hawkins removes newer construction and separately alienable single-family homes and condominiums from local rent regulation, and permits vacancy decontrol. Where a local ordinance does apply and is stricter than the statewide cap, the local ordinance governs and the state cap does not.
California Rent Control by City: The Three Layers
Sections below are marked for the side they speak to. This one is the map both sides need.
| Layer | Source | What it does |
|---|---|---|
| Ceiling on local power | Costa-Hawkins, Civ. Code Secs. 1954.50-1954.535 | Exempts newer construction and separately alienable units from local rent regulation; permits vacancy decontrol |
| Statewide baseline | Civ. Code Secs. 1947.12 and 1946.2 | Caps increases at 5 percent plus regional CPI or 10 percent, whichever is lower; requires just cause after 12 months |
| Local ordinance | City or county charter or ordinance under the police power | May set a lower increase limit, add just cause grounds, require registration, and impose its own penalties |
The layers are not cumulative in the way people expect. Costa-Hawkins tells a city what it may not reach at all. The Tenant Protection Act then applies to units the city does not regulate more strictly. And where the city does regulate more strictly, the state provisions step back rather than stack.
That last point is where most confusion lives, and both state sections say it plainly. Section 1947.12(d)(3) provides that the state cap does not apply to housing subject to rent or price control through a public entity’s valid exercise of its police power, consistent with Costa-Hawkins, that restricts annual increases to an amount less than the state cap. Section 1946.2(i)(2) provides that residential real property shall not be subject to both a local just cause ordinance and the state section.
Costa-Hawkins: What a City Cannot Do
Civil Code section 1954.50 gives the chapter its name: the Costa-Hawkins Rental Housing Act. Section 1954.52(a) is the operative exemption.
An owner may establish the initial and all subsequent rental rates for a dwelling or unit about which any of three things is true. It has a certificate of occupancy issued after February 1, 1995. It was already exempt from a public entity’s rent control ordinance on or before February 1, 1995 under a local exemption for newly constructed units. Or it is alienable separate from the title to any other dwelling unit, or is a subdivided interest in a subdivision as specified in Business and Professions Code section 11004.5(b), (d), or (f).
The third is the one that does the work. A single-family home is alienable separate from any other dwelling unit, and so is a condominium that has been sold separately. Between them, they are why a great deal of housing in rent-controlled cities is not rent-controlled.
Two exceptions sit inside it at section 1954.52(a)(3)(B). The exemption does not apply where the preceding tenancy was terminated by the owner’s notice under Civil Code section 1946.1 or by a change in the terms of the tenancy noticed under section 827. And it does not apply to a condominium that has not been sold separately by the subdivider to a bona fide purchaser for value, subject to a further carve-back where the unit meets the new-construction tests or where all units but one have been sold and the subdivider has occupied the remaining one as a principal residence for at least a year.
Section 1954.52 has two more limits worth knowing. Subdivision (b) removes the exemption where the owner has agreed by contract with a public entity in consideration for a direct financial contribution or other density bonus assistance. And subdivision (d) removes it for any unit containing serious health, safety, fire, or building code violations, excluding disaster-caused ones, for which a citation issued and which remained unabated for six months or longer preceding the vacancy.
Section 1954.53 handles vacancies. Subdivision (a) lets an owner set the initial rental rate for a dwelling or unit, except where the previous tenancy was terminated by the owner’s section 1946.1 notice or by a section 827 change in terms other than a lawful rent or fee change, and except where the owner contracted with a public entity for assistance. Subdivision (f) removes vacancy decontrol where the unit was cited for serious violations under Health and Safety Code section 17920.3, the citation issued at least 60 days before the vacancy, and the violation was still unabated when the prior tenant left and had remained so for 60 days or longer.
Both sections close the same way: nothing in them affects a public entity’s authority to regulate or monitor the grounds for eviction. Costa-Hawkins limits rent regulation, not eviction regulation.
Local Rent Ordinance vs AB 1482: Which One Governs?
One of them, not both, and which one depends on two questions.
Is the unit exempt from local control under Costa-Hawkins? If yes, the local rent limit does not reach it, and the analysis moves to the state cap and its own exemption list at section 1947.12(d) – which is not the same list.
If the local ordinance does reach it, is the local limit stricter? If the ordinance restricts annual increases to less than the state cap allows, section 1947.12(d)(3) takes the unit out of the state cap and the ordinance governs alone.
Just cause runs on a parallel but separately worded track. Section 1946.2(i)(1)(A) provides that a local just cause ordinance adopted on or before September 1, 2019 applies instead of the state section. Subparagraph (B) provides that an ordinance adopted or amended after that date applies if it is more protective, which the statute defines by three criteria: the local just cause grounds are consistent with the state section; the ordinance further limits the reasons for termination, provides higher relocation amounts, or adds tenant protections not otherwise prohibited; and the local government made a binding finding within the ordinance that it is more protective. Paragraph (3) adds that a less protective ordinance adopted after September 1, 2019 is unenforceable unless the state section is repealed.
For landlords, the practical consequence is that “we follow AB 1482” is not a compliance position in a city with its own ordinance. For tenants, it means a right that exists under the state section may not be the right that applies to your unit, and the local one is often better.
How Do I Find the Ordinance That Applies to My Unit?
Four checks, in order, and all four are documentary.
Find the certificate of occupancy date. A certificate issued after February 1, 1995 exempts the unit from local rent control under section 1954.52(a)(1), and a certificate issued within the previous 15 years exempts it from the state cap under section 1947.12(d)(4). Those are different tests with different dates, and a unit can fail one and pass the other. The building department that issued it is the source.
Determine whether the unit is alienable separate from title. Single-family homes and separately sold condominiums generally are; apartments in a multi-unit building generally are not. The recorded title documents answer this, not the lease.
Check whether the property is in a jurisdiction with a rent stabilization ordinance California law permits it to enforce, and read the ordinance itself – its coverage section, its exemption list, and its adoption and amendment dates, which decide the section 1946.2(i) question. The city’s municipal code and, where one exists, the rent board or rent stabilization program are the sources.
Confirm the state exemption notice. If the claim is that the unit is exempt under section 1947.12(d)(5) or section 1946.2(e)(8), the exact statutory notice must have been given, and for tenancies commenced or renewed on or after July 1, 2020 it must be in the rental agreement. An exemption asserted without that notice is not established.
Why This Post Does Not List the Cities
Because a list is the part that goes wrong.
Ordinances are adopted, amended, and repealed on local calendars, coverage thresholds and exemption lists differ between neighboring cities, and several jurisdictions have amended their rules since the state Tenant Protection Act took its current form. A list published today over a law firm’s name would be relied on tomorrow by someone whose city changed its ordinance last month, and the failure mode is not an inaccurate article – it is a rent increase served under the wrong rule or a termination notice missing a local requirement.
The method above produces a current answer. A list produces a stale one. Where a specific address matters, the ordinance text and the rent board’s own published materials are the sources to check, and neither takes long.
Registration, Filing, and Duties State Law Does Not Impose
This is the practical difference between the layers, and it is entirely local.
State law imposes no registration requirement on residential landlords. Local rent stabilization programs commonly do, and the duties can include registering each covered unit, filing the rent in effect, paying a per-unit fee, filing petitions for increases above the standard adjustment, serving notices in prescribed local forms, and filing a copy of a termination notice with the local agency. Some ordinances make compliance with registration a precondition to raising rent or to maintaining an unlawful detainer.
This post does not state which cities require what, for the same reason it publishes no list. What it does say is that a landlord operating in a rent-stabilized jurisdiction should treat the registration file as part of the tenancy file, because the consequence of a gap tends to surface at the worst moment – when a rent increase or a termination is challenged.
What Penalties Apply for Violating a Local Ordinance?
The honest answer has two parts, and only one of them can be stated generally.
The local part varies. Ordinances commonly provide for administrative penalties, restitution of excess rent, treble damages in some jurisdictions, tenant civil actions, and a defense to an unlawful detainer where the increase or the notice did not comply. Which of those a given city provides, and in what amount, is in the ordinance.
The state part is fixed and applies where the state sections govern. Section 1947.12(k) gives a tenant charged above the cap injunctive relief, damages equal to the overcharge, attorney’s fees and costs in the court’s discretion, and up to three times the overcharge on a showing of willfulness, oppression, fraud, or malice, with a three-year limitations period. Section 1946.2(h) gives a tenant whose possession was sought in material violation of the just cause section actual damages, discretionary fees and costs, treble damages on the same showing, and punitive damages, and lets the Attorney General, a city attorney, or county counsel seek injunctive relief. Waivers are void under sections 1947.12(l) and 1946.2(j).
When to Bring Counsel In
Three triggers. Before relying on a Costa-Hawkins exemption, because the exemption turns on the certificate of occupancy date or separate alienability rather than on the building’s appearance, and because subdivisions 1954.52(d) and 1954.53(f) take it away where a cited violation went unabated. Before serving a rent increase or a termination in a jurisdiction with its own ordinance, because the local form, filing, and registration requirements are conditions rather than formalities. And whenever the question is which layer governs, since section 1947.12(d)(3) and section 1946.2(i) make that a threshold question rather than a detail.
Several adjacent questions are covered separately: how the statewide rent cap and just cause rules work in detail, which notice a landlord has to serve and for how long, what defenses arise once an eviction has been filed, what a landlord’s remedies look like when a tenant breaches, and how a fixed-term lease differs from a month-to-month tenancy.

Frequently Asked Questions
How do local rent control ordinances interact with AB 1482?
One set of rules governs, not both. Where a local ordinance restricts annual increases to less than the statewide cap allows, Civil Code section 1947.12(d)(3) takes the unit out of the state cap and the ordinance controls. On the eviction side, section 1946.2(i) provides that a property is never subject to both a local just cause ordinance and the state section: an ordinance adopted on or before September 1, 2019 applies instead, and a later one applies only if it is more protective and the local government made a binding finding to that effect within the ordinance.
Which California cities have their own rent and eviction rules?
A number of California cities and counties have adopted rent stabilization or just cause ordinances under their police power, and others have amended or expanded theirs since the statewide Tenant Protection Act took effect. This article deliberately does not publish a list, because ordinances are adopted, amended, and repealed on local calendars and a list goes stale between publication and use. The reliable answer for a specific address comes from the city’s own municipal code and, where one exists, its rent board or rent stabilization program.
How do I find the ordinance that applies to my unit?
Work through four documents. Get the certificate of occupancy date from the building department, since a date after February 1, 1995 exempts the unit from local rent control and a date within the previous 15 years exempts it from the state cap. Check the recorded title to see whether the unit is alienable separate from any other dwelling unit. Read the city’s ordinance itself, including its coverage, exemptions, and adoption date. And confirm that any claimed state exemption was accompanied by the exact statutory notice.
What extra registration and filing duties do local laws impose on landlords? State law imposes no registration requirement, so everything in this category comes from the ordinance. Local programs commonly require registering each covered unit, filing the rent in effect, paying a per-unit fee, petitioning for increases above the standard adjustment, using prescribed local notice forms, and filing termination notices with the local agency. Some ordinances make registration a precondition to raising rent or to maintaining an unlawful detainer, which is why the registration file belongs with the tenancy file.
What penalties apply for violating a local ordinance?
Local penalties vary and are set by the ordinance, commonly including administrative penalties, restitution of excess rent, tenant civil actions, and a defense to an unlawful detainer. The state penalties are fixed where the state sections govern: a tenant charged above the statewide cap may seek injunctive relief, the amount of the overcharge, discretionary attorney’s fees, and up to three times the overcharge on a showing of willfulness, oppression, fraud, or malice, within three years. A material violation of the just cause section carries actual damages, fees, treble damages, and punitive damages.
