Just Cause for eviction means the Landlord has a good reason for terminating a tenancy, generally either failure to pay rent, or breach of the lease by the tenant. Reasons are stated in California Code of Civil Procedure and detailed in Dept. of Fair Employment and Housing definition. Tenants in all rental units (unless exempted as described above) with an initial certificate of occupancy before the Effective Date of CSFRA, 12/23/16, are subject to Just Cause protection. The Tenant Protection Act passed in 2019 has modified California law.
