Just cause eviction rules in Ontario, CA — sometimes called tenant protection or "for cause" eviction ordinances — list the specific legal reasons a landlord can end a tenancy.
Ontario follows California AB 1482 (Civil Code 1946.2), requiring landlords to provide just cause to terminate tenancy after 12 months of occupancy, with relocation assistance for no-fault evictions.
Ontario does not have a separate local just cause eviction ordinance, so tenancies in the city are governed by the California Tenant Protection Act (AB 1482), codified at Civil Code 1946.2. Once a tenant has occupied a unit for 12 months (or 24 months where an additional adult is added), the landlord may terminate tenancy only for at-fault reasons (nonpayment of rent, lease breach, nuisance, criminal activity) or no-fault reasons (owner or relative move-in, substantial remodel, withdrawal from market, or compliance with a government order). For any no-fault termination, the landlord must pay the tenant one month of rent in relocation assistance or waive the final month of rent, and must serve a written notice citing the specific just cause basis. Exemptions apply to single-family homes owned by individuals (not corporations) if proper notice is given, newly constructed housing less than 15 years old, and owner-occupied duplexes. Before filing an unlawful detainer for a curable lease violation, the landlord must serve a 3-day notice to cure. Violations can be raised as affirmative defenses in eviction court and may expose the landlord to treble damages under Civil Code 1946.2(h).
