California's Tenant Protection Act (AB 1482) established statewide rent caps that limit how much landlords can increase rent each year. Understanding these rules is critical to staying compliant and avoiding penalties.
Statewide Rent Cap
Official Law Citation: The rules and regulations outlined on this page are strictly configured under the official California Tenant Protection Act (AB 1482). Landlords must always ensure their lease agreements directly adhere to this state code.
For properties covered by AB 1482, the maximum annual rent increase is:
5% + local Consumer Price Index (CPI), or 10% - whichever is LOWER
This cap applies per 12-month period. Landlords cannot increase rent more than once in any 12-month period.

Exempt Properties The following are exempt from the statewide rent cap:

Compliance Process Timeline in california
Determine Exemption
Check if the property is subject to AB 1482 (Tenant Protection Act) rent caps.
Calculate Allowed Increase
Calculate the max increase (5% + CPI, max 10%) if strictly subject to rent control.
Serve Notice
Provide 30 days written notice for increases under 10%, or 90 days for increases over 10% (for exempt properties).
Best Practices
- Calculate CPI before each increase - Check your local CPI published by the Bureau of Labor Statistics
- Document the calculation - Keep records showing your increase is within the cap
- Serve proper notice - Use the correct notice period (30 or 90 days)
- Check local rules first - Your city may have stricter limits
- Include AB 1482 disclosure - Notify tenants whether the property is covered or exempt
