Rent Increase Laws in California
Your landlord just hit you with a rent increase. Before you panic or sign anything, here's what California law actually says they can and can't do.
Statewide cap under the Tenant Protection Act of 2019 (AB 1482, Cal. Civ. Code § 1947.12): 5% plus the change in a regional CPI, or 10%, whichever is lower, over any 12-month period, limited to two increases per 12 months. Applies broadly, but covered units exclude housing built within the last 15 years (rolling), deed-restricted affordable housing, dormitories, units already under a stricter local rent-control ordinance, and most single-family homes/duplexes not owned by a corporation, REIT, or qualifying LLC (with proper notice to the tenant). Multiple cities also have stricter local rent-control ordinances.

•Rent Control
Does California Have Rent Control?
Yes. Statewide cap under the Tenant Protection Act of 2019 (AB 1482, Cal. Civ. Code § 1947.12): 5% plus the change in a regional CPI, or 10%, whichever is lower, over any 12-month period, limited to two increases per 12 months. Applies broadly, but covered units exclude housing built within the last 15 years (rolling), deed-restricted affordable housing, dormitories, units already under a stricter local rent-control ordinance, and most single-family homes/duplexes not owned by a corporation, REIT, or qualifying LLC (with proper notice to the tenant). Multiple cities also have stricter local rent-control ordinances.
California caps most annual rent increases at 5% plus the change in a regional Consumer Price Index, or 10%, whichever is lower, under Cal. Civ. Code § 1947.12 (AB 1482). Covers most rental units, but excludes housing built within the last 15 years (rolling), deed-restricted affordable housing, dormitories, units already under a stricter local rent-control ordinance, and most single-family homes/duplexes not owned by a corporation, REIT, or qualifying LLC (with proper notice).
Increases are limited to once per 12 months. Landlords cannot stack multiple increases to get around the cap.
•Notice Requirements
How Much Notice Must Your Landlord Give?
California law requires written notice before a rent increase, and the period varies — notice period depends on the size of the increase, not tenancy length: 30 days for an increase of 10% or less (cumulative over the trailing 12 months), 90 days for an increase of more than 10% (cumulative over the trailing 12 months) — under Cal. Civ. Code § 827.
- 30 days — an increase of 10% or less (cumulative over the trailing 12 months)
- 90 days — an increase of more than 10% (cumulative over the trailing 12 months)
The notice must be in writing. A verbal mention in passing does not count. If your landlord failed to give proper written notice, you do not owe the increased amount until the notice period has fully elapsed.
•Local Ordinances
Cities in California With Their Own Rent Control
These cities have local rent control ordinances that may be stricter than state law. If you live in one of these cities, the local rules apply to your unit — check directly with your city's rent board.
| City | Cap | Details |
|---|---|---|
| Los Angeles | Varies | LA Rent Stabilization Ordinance (LARSO): annual adjustment set by Rent Adjustment Commission, typically 3-8%. Covers units built before 10/1/1978. |
| San Francisco | Varies | SF Rent Ordinance: annual allowable increase set by Rent Board, tied to 60% of Bay Area CPI. Covers units built before 6/13/1979. |
| Oakland | Varies | Oakland Rent Adjustment Program: annual CPI-based increase set by Rent Board. Covers units built before 1/1/1983. |
| San Jose | 5% | Apartment Rent Ordinance: 5% annual cap. Covers units built before 9/7/1979. |

•Exemptions
What Units Are Exempt From Rent Control in California?
Even in states with rent control, not every unit is covered. These categories are typically exempt:
- Housing built within the last 15 years
- Single-family homes not owned by corporations (with proper notice)
- Owner-occupied duplexes
- Affordable housing deed-restricted units
- Dormitories
If your landlord claims your unit is exempt, ask them to cite the specific statute. “It's exempt” is not a legal argument — the exemption has to actually apply to your building and your tenancy.
•Take Action
What to Do If Your Rent Increase Seems Illegal
- Check the math. If California has a cap, calculate whether the increase exceeds it. If there is no cap, check whether the notice period was met (the notice period that applies to your tenancy (see above) under Cal. Civ. Code § 827).
- Check the timing. Mid-lease increases are generally unenforceable unless your lease explicitly allows them. Pull your lease and read it.
- Check for retaliation. Did you file a complaint, request repairs, or join a tenant organization in the last 6 months? A rent increase right after any of those is legally suspect.
- Negotiate. Even in states without rent control, landlords prefer keeping reliable tenants. Counter with a smaller increase, a longer lease term, or a delayed effective date. Get it in writing.
- Escalate if needed. File a complaint with your local rent board or housing authority. You do not need a lawyer to do this.
•Market Data
How to Check If Your Rent Is Fair
Even if your landlord's increase is technically legal, that does not mean it reflects reality. Use these tools to check whether you're being asked to pay more than the market supports:
- HUD Fair Market Rent (FMR) data — huduser.gov. The federal government publishes annual FMR estimates by county. If your new rent is significantly above the FMR for your area, you have a negotiation data point.
- Zillow / Apartments.com — search comparable units in your building or neighborhood. Screenshot the listings — this is evidence if you negotiate.
- Local tenant organizations — many maintain rent surveys and can tell you what others in your area are paying.
When you negotiate, lead with data, not emotion. “Comparable units in this ZIP code are renting for $X, and HUD's FMR for this county is $Y” is more effective than “this increase is unfair.”

Frequently Asked Questions
Does California have rent control?
Yes. Statewide cap under the Tenant Protection Act of 2019 (AB 1482, Cal. Civ. Code § 1947.12): 5% plus the change in a regional CPI, or 10%, whichever is lower, over any 12-month period, limited to two increases per 12 months.

Multiple cities also have stricter local rent-control ordinances. Check local ordinances — some cities have stricter caps than the state.
How much notice does my California landlord have to give before raising rent?
California law requires written notice before a rent increase, and the period varies — notice period depends on the size of the increase, not tenancy length: 30 days for an increase of 10% or less (cumulative over the trailing 12 months), 90 days for an increase of more than 10% (cumulative over the trailing 12 months) — under Cal. Civ. Code § 827. If your landlord gave you less notice than that, the increase may not be enforceable.
Can my landlord raise my rent during a lease in California?
Generally, no. If you have a fixed-term lease, your landlord cannot raise rent until the lease expires — unless the lease itself contains a clause allowing mid-term increases. Month-to-month tenants can receive increases with the notice period that applies to your tenancy (see above) under Cal. Civ. Code § 827.
What can I do if my rent increase seems unfair in California?
If your increase exceeds the legal cap, you can file a complaint with your local rent board or housing authority. Document the increase amount, the date you received notice, and the applicable statute. You are not required to pay the illegal portion while the dispute is pending.
Is there a maximum rent increase in California?
Yes. California caps most annual rent increases at 5% plus the change in a regional Consumer Price Index, or 10%, whichever is lower, under Cal. Civ. Code § 1947.12 (AB 1482). Covers most rental units, but excludes housing built within the last 15 years (rolling), deed-restricted affordable housing, dormitories, units already under a stricter local rent-control ordinance, and most single-family homes/duplexes not owned by a corporation, REIT, or qualifying LLC (with proper notice). Increases are limited to once per 12 months.
