California rent increase limits depend on the year and whether your city has its own rent control

California state law caps annual rent increases at 5 percent or the cost of living plus 2 percent, whichever is lower. For 2024, that means a maximum of 5 percent statewide. For 2025, the limit is 3.25 percent. These numbers change each year based on inflation data released in October.

However, many California cities and counties have stricter limits. San Francisco, Los Angeles, Oakland, San Diego, and Berkeley all have their own rent control ordinances that may allow smaller increases or require just cause for any increase at all. If you live in one of these cities, your landlord must follow the local rule, not the state rule — and the local rule is almost always lower.

The state law also requires your landlord to give you 30 days' written notice before raising your rent. If the increase is more than 10 percent, they must give 60 days' notice instead.

Key Takeaways

  • California state law limits rent increases to 5 percent or the cost of living plus 2 percent (whichever is lower) each year, and the percentage changes annually based on inflation.
  • Many California cities including San Francisco, Los Angeles, Oakland, and Berkeley have local rent control laws that set lower limits than the state allows.
  • Your landlord must give you 30 days' written notice before a rent increase of 10 percent or less, and 60 days' notice for increases above 10 percent.
  • Rent increases are not allowed during the first year of a tenancy, and some cities require landlords to prove just cause before raising rent at all.

When your landlord cannot raise rent at all

California law prohibits any rent increase during your first 12 months as a tenant. After that, increases are allowed — but only if your landlord gives proper notice and stays within the legal limit.

Some cities go further and require just cause — a legitimate reason — before a landlord can raise rent at all. In San Francisco and Oakland, for example, a landlord must show that the increase is needed to cover increased operating costs, capital improvements, or property taxes. Without just cause, the increase is not allowed, even if it is below the percentage limit. Check your city's housing department website or call 311 to find out whether your city requires just cause.

How to find out what your city allows

Start by searching "[your city name] rent control ordinance" or "[your city name] rent increase limits." Most cities post this information on their housing or planning department website. If you cannot find it online, call your city's housing authority or tenant rights office directly — they can tell you the exact limit for your address in minutes.

If your city does not have its own ordinance, the state law applies: 5 percent or cost of living plus 2 percent, whichever is lower. You can find the current year's limit on the California Department of Consumer Affairs website, which updates the number each October.

Keep the notice your landlord gives you. If the increase exceeds the legal limit for your city or state, you have grounds to dispute it. Some tenants send a written response to their landlord citing the law and the correct limit; others contact a local tenant rights organization for help.

What counts as a rent increase under California law

A rent increase means any rise in the monthly rent amount. It does not include increases to utilities, parking fees, or other charges — those are separate and have different rules. However, if your lease lists utilities as included in rent and your landlord tries to charge you separately, that is effectively a rent increase and must follow the same notice and percentage limits.

Increases to deposits, parking fees, or pet fees are not considered rent increases and do not have to follow the percentage cap. However, your landlord still cannot raise these fees without proper notice, and some cities have their own rules about deposit increases.

The difference between the state law and local rent control

California's state law (called the Tenant Protection Act) sets a floor — a minimum protection that applies everywhere. Local rent control ordinances set a ceiling — they can be stricter but never looser. If your city has rent control, follow your city's rules, not the state percentage.

For example, San Francisco allows increases of 0.55 percent to 0.75 percent per year (the exact number changes annually), which is far lower than the state's 5 percent. Los Angeles allows up to 3 percent or the cost of living plus 1.5 percent, whichever is lower. Oakland allows 2 percent or the cost of living plus 1.5 percent, whichever is lower. If you live in one of these cities and your landlord tries to raise your rent by the state limit instead of the city limit, the city limit is what matters.

What to do if your landlord raises rent illegally

If your landlord raises your rent above the legal limit or without proper notice, you have options. First, send a written response citing the law and the correct limit. Many landlords will back down once they realize you know the rules.

If your landlord does not respond, contact your city's tenant rights office or a local legal aid organization. Many offer free consultations and can send a formal letter on your behalf. In some cases, you can file a complaint with your city's rent board or housing authority, which may investigate and order your landlord to refund the illegal increase.

You can also withhold the illegal portion of the increase and keep it in a separate account, though this is risky — consult a tenant rights organization first. Some tenants use the illegal increase as a defense if their landlord tries to evict them for non-payment.

How the cost-of-living calculation works

The state limit is the lower of two numbers: 5 percent, or the cost of living plus 2 percent. The cost of living is measured by the Consumer Price Index for the San Francisco Bay Area, released each October by the U.S. Bureau of Labor Statistics. That number applies to all of California, not just the Bay Area.

For example, if the October 2024 index showed 1.25 percent inflation, the state limit for 2025 would be 1.25 percent plus 2 percent, which equals 3.25 percent — lower than the 5 percent cap, so 3.25 percent is the limit. The California Department of Consumer Affairs publishes the new limit each October, so you can check it before your landlord sends a notice.

Frequently Asked Questions

Can my landlord raise rent twice in one year?

No. California law allows one rent increase per 12 months. If your landlord raised your rent in January, they cannot raise it again until January of the following year. Some cities have even stricter rules — check your local ordinance to be sure.

What if I signed a lease that says my landlord can raise rent by any amount?

That clause is not enforceable. California law overrides any lease language that allows increases above the legal limit. Your landlord cannot use a lease to bypass the state or local rent cap, no matter what you both signed.

Does the rent increase limit explore to month-to-month tenants?

Yes. Month-to-month tenants have the same protections as lease tenants. Your landlord must still give 30 or 60 days' notice and stay within the legal percentage limit. The only difference is that month-to-month tenants can be evicted without cause after the notice period (in cities without just-cause rules), but the rent increase rules are identical.

If I move to a new apartment, does the limit explore to the first month's rent?

No. The rent increase limit applies only to existing tenancies. When you sign a new lease with a new landlord or move to a new unit, the first month's rent can be any amount the landlord and tenant agree on. The cap kicks in only for the second year and beyond.

How do I know if my city has rent control?

Search your city name plus "rent control" or call your city's housing department. Major California cities with rent control include San Francisco, Los Angeles, Oakland, Berkeley, San Diego, and Santa Monica. If you cannot find local rules, the state law applies to you.
