For covered units, annual rent increases are capped at 5% plus the regional inflation rate (CPI), but never more than 10% total in 12 months. The exact cap changes every August and varies by region — for Aug 2025–Jul 2026 it runs roughly 6%–9% depending on the metro area.
The Tenant Protection Act of 2019 (AB 1482), codified at Civil Code §1947.12, limits rent increases to 5% + the percentage change in the regional Consumer Price Index, capped at 10% total over any 12-month period. Because CPI is published regionally each year, the maximum legal increase differs by area and resets each August. Landlords may not make more than two increases in a 12-month period, and the combined total still cannot exceed the cap. Always verify the current regional CPI figure before raising rent. Local rent-control ordinances (see 'Local rent control') can impose stricter limits that override AB 1482.
