Summary

California Civil Code section 1946.2 requires landlords of covered Riverside County rentals to include a specific just-cause and rent-cap disclosure in every lease and in a separate notice to existing tenants. Failure to deliver the notice undermines later eviction efforts.

City-specific rules exist: Riverside has its own ab-1482 notice disclosure rules that differ from Riverside County's county-level regulations. If you live in Riverside, check the city-specific page instead.

(f) An owner of residential real property subject to this section shall provide notice to the tenant as follows: (1)(A) Except as provided in subparagraph (B), for any tenancy commenced or renewed on or after July 1, 2020, in the lease or rental agreement, as an addendum to the lease or rental agreement, or as a written notice signed by the tenant, with a copy provided to the tenant. (B) For a tenancy in a mobilehome commenced or renewed on or after July 1, 2022, as an addendum to the lease or rental agreement, or as a written notice signed by the tenant, with a copy provided to the tenant. (2)(A) Except as provided in subparagraph (B), for a tenancy existing prior to July 1, 2020, by written notice to the tenant no later than August 1, 2020, or as an addendum to the lease or rental agreement. (B) For a tenancy in a mobilehome existing prior to July 1, 2022, by written notice to the tenant no later than August 1, 2022, or as an addendum to the lease or rental agreement. (3) The notification or lease provision shall be in no less than 12-point type, and shall include the following: 'California law limits the amount your rent can be increased. See Section 1947.12 of the Civil Code for more information. California law also provides that after all of the tenants have continuously and lawfully occupied the property for 12 months or more or at least one of the tenants has continuously and lawfully occupied the property for 24 months or more, a landlord must provide a statement of cause in any notice to terminate a tenancy. See Section 1946.2 of the Civil Code for more information.' The notification or lease provision shall be subject to Section 1632. (g) An owner's failure to comply with any provision of this section shall render the written termination notice void.

Full Breakdown

AB 1482 applies to most multifamily buildings older than fifteen years across Riverside County, including units in unincorporated areas. Landlords must provide the statutory disclosure either inside the lease as an addendum or through a separate signed notice for tenants whose tenancies began before July 2020. The disclosure explains the annual rent cap of five percent plus regional CPI, capped at ten percent total, and the just-cause eviction protections that kick in after twelve months of occupancy. Single-family homes owned by individuals with proper Costa-Hawkins notices are exempt.

Violations & Fines

Omitting the AB 1482 notice can prevent the landlord from enforcing market rent increases above the cap and can defeat a no-fault eviction in court.

Frequently Asked Questions

Does AB 1482 cover single-family homes in RivCo?
Usually not. Costa-Hawkins exempts single-family homes owned by individuals if the landlord provides the statutory exemption notice. Corporate-owned single-family homes do remain covered.
When must the disclosure be delivered?
At lease signing for new tenancies, and as a separate signed notice for tenancies that began before July 1, 2020, before any rent increase or eviction notice can be issued.
