How often and how much can a landlord raise a tenant’s rent?

Assembly Bill 1482 (The Tenant Protection Act of 2019) regulates rent increases. As of August 1, 2022 ONLY for covered properties the rent cap is 10%. Proper notice means that an increase of less than 10% requires 30 days written notice before the increase takes effect. However, increases of more than 10% in any 12 month period, requires 90 days written notice before the increase takes effect. (For more information regarding proper notice, please see the section on defective notices.)
