California rent increases and just-cause rules for owners

Short answer

For most California rentals, a yearly rent increase is capped at 5% plus local inflation, never more than 10% in 12 months (AB 1482). Increases of 10% or less need 30 days' written notice; above 10%, 90 days. After a tenant has lived there 12 months, you generally need a reason listed in the law to end the tenancy.

The rent cap (AB 1482)

For covered homes, the total increase over 12 months can be at most 5% plus the regional change in the cost of living (CPI), and never more than 10%. The Attorney General publishes the current maximum by region.

Who is not covered

Notice for rent increases

Give written notice at least 30 days ahead for increases of 10% or less within 12 months, and 90 days ahead above 10% (Civil Code 827). Mailed notices need extra days.

Just cause

After a tenant has lived in a covered home for 12 months, you generally need a reason listed in Civil Code 1946.2. "At-fault" reasons include non-payment and serious lease breaches. "No-fault" reasons, such as moving in yourself or major renovation, usually require relocation help equal to one month's rent.

Local rules

Many California cities have their own, stricter rent and eviction rules. Check the Attorney General's list and your city before you act.
