California Rent Increase Limits Effective August 1, 2026: New Maximums by Area
The new California statewide rent-increase maximums for August 1, 2026 through July 31, 2027, plus the local-law checks landlords and tenants should make.
New statewide maximums started August 1
The California Attorney General's current statewide chart lists the maximum Tenant Protection Act increases for covered rentals taking effect from August 1, 2026 through July 31, 2027.
Los Angeles and Orange Counties: 8.7%. Riverside and San Bernardino Counties: 8.1%. San Diego County: 8.2%. Alameda, Contra Costa, Marin, San Francisco, and San Mateo Counties: 8.8%. All other counties: 8.6%.
Why the percentage changes by area
The Tenant Protection Act uses 5% plus the applicable change in the cost of living, capped at 10%. California uses specified metropolitan-area CPI data where available and California CPI data for other counties.
A local ordinance may set a lower number
The statewide percentage is not automatically the number a landlord may use. The Attorney General's current local chart shows, for example, a 3% annual adjustment for qualifying City of Los Angeles RSO units for July 1, 2026 through June 30, 2027, and different limits for other rent-stabilized cities.
Check the property before serving notice
Identify the exact city and county, confirm whether the property is covered by the statewide law, check for a local rent-control ordinance, calculate the cumulative increase over the relevant 12-month period, and verify notice timing before serving a rent increase.
