How Rent Increases Work in California

AB 1482 limits annual rent increases to CPI + 5%, capped at 10%, for covered residential units. The CPI used is the regional CPI-U published by BLS for the 12-month period ending March 31 of each year.

At the statewide median gross rent of $1,881/month, the 8.3% cap translates to a maximum increase of $156/month ($1,873/year) for a median-rent unit.
