Frequently Asked Questions

What is AB 1482?

AB 1482, the California Tenant Protection Act, limits annual rent increases to 5% plus the local Consumer Price Index (CPI) change, or 10%, whichever is lower. It applies to most residential rental properties in California built more than 15 years ago.

How is the rent cap calculated?

The maximum annual increase is 5% + the April-to-April CPI change for your region, capped at 10%. The CPI component uses the BLS Consumer Price Index for All Urban Consumers (CPI-U) for the metropolitan area where the property is located.

Which properties are exempt from AB 1482?

Exempt properties include: new construction (built within the last 15 years), single-family homes owned by individuals who have given proper written notice, owner-occupied duplexes, deed-restricted affordable housing, and units already covered by a local rent control ordinance that is stricter than AB 1482.

What if my city has its own rent control?

If your city has a local rent control ordinance with a lower cap than AB 1482 (e.g., Los Angeles RSO at 3%, San Francisco at 1.4%), the stricter local rate applies. This calculator checks for local ordinances and shows the applicable rate.

How much notice do I need to give?

Per California Civil Code 827, landlords must give at least 30 days written notice for rent increases of 10% or less within a 12-month period, and 90 days for increases exceeding 10%.

When does AB 1482 expire?

AB 1482 is currently set to expire on January 1, 2030. Legislation has been proposed to extend or make the protections permanent, but as of 2026, the sunset date remains 2030.
