How to use this calculator
- 1
Enter your current monthly rent and select your region — AB 1482 uses regional CPI (Consumer Price Index).
- 2
If your landlord has already raised rent in the past 12 months, enter that percentage — the cap applies to the rolling 12-month total.
- 3
AB 1482 applies to most multi-family housing built more than 15 years ago. Many properties are exempt.
- 4
Always check if your local city has stricter rent control — some cities (Los Angeles, San Jose, Oakland) have stronger protections.
Frequently asked questions
What properties are covered by AB 1482?
AB 1482 covers most rental housing in California built more than 15 years ago (on a rolling basis). Exempt properties include: single-family homes (unless owned by a corporation or REIT), condos (unless owned by a corporation), buildings built in the last 15 years, and units covered by stronger local rent control (LA, SF, Oakland, San Jose, etc.).
Can my landlord raise rent more than 10%?
Under AB 1482, no — the maximum is 5% + local CPI, capped at 10%, in any 12-month period. However, landlords can go above this for new tenants — the cap applies during tenancy, not between tenancies. Once a tenant moves out, landlords can set any new rent for the next tenant.
Does AB 1482 prevent evictions?
Yes — AB 1482 also requires "just cause" for eviction for covered tenancies. Allowable causes include: non-payment of rent, nuisance, illegal activity, owner move-in, withdrawal from rental market, or demolition. "No-fault" evictions (owner move-in, demolition) typically require relocation assistance of one month's rent.
Is my city covered by stronger rent control?
Many California cities have rent control ordinances stricter than AB 1482: Los Angeles (RSO — applies to buildings built before 1978, with smaller annual increases), San Francisco (very strict rent control plus just cause eviction), Oakland (CPI-based), San Jose (5% max or CPI, whichever is lower), Berkeley, Santa Monica. Always check your local ordinance.

AB 1482 by the numbers
California's Tenant Protection Act (AB 1482, effective January 2020) limits rent increases to 5% + local CPI, never more than 10%, in any rolling 12-month period. With 2024 LA CPI at ~3.4%, that's a maximum of 8.4% per year. On a $2,500/month unit, the max increase is $210/month. Landlords who exceed this can face penalties and must reverse unauthorized increases.
How the 15-year rolling exemption works
AB 1482 only protects units built more than 15 years before the current year. In 2024, this means buildings completed before 2009 are covered. A building completed in 2010 becomes covered in 2025. This rolling exemption was designed to avoid discouraging new housing construction — new buildings can command market rent to pencil out their construction costs.
