Summary

California AB 1482 (Tenant Protection Act of 2019) requires landlords countywide in Orange County to provide written notice of statewide rent caps and just-cause eviction protections, or to certify a property's exemption status, in every lease and renewal.

City-specific rules exist: Santa Ana, and Anaheim have their own ab-1482 notice disclosure rules that differ from Orange County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

“This property is not subject to the rent limits imposed by Section 1947.12 of the Civil Code and is not subject to the just cause requirements of Section 1946.2 of the Civil Code. This property meets the requirements of Sections 1947.12 (d)(5) and 1946.2 (e)(8) of the Civil Code and the owner is not any of the following: (1) a real estate investment trust, as defined by Section 856 of the Internal Revenue Code; (2) a corporation; or (3) a limited liability company in which at least one member is a corporation.”

(ii) (I) Except as provided in subclause (II), for a tenancy existing before July 1, 2020, the notice required under clause (i) may, but is not required to, be provided in the rental agreement.

Full Breakdown

AB 1482 (Civil Code 1946.2 and 1947.12) applies to most rental units in Orange County and requires landlords to give tenants written notice that the property is subject to statewide rent and eviction limits, capping annual increases at 5% plus CPI (max 10%). Single-family homes owned by individuals (not corporate or REIT) are exempt only if a separate exemption notice is delivered. The disclosure must appear in the lease or be provided as an addendum signed by the tenant. Failure to disclose can result in loss of exemption and tenant remedies. The law operates alongside Costa-Hawkins, which preempts vacancy-decontrol limits.

Violations & Fines

Failing to provide AB 1482 disclosure, omitting required exemption notice for single-family rentals, or charging rent above the cap can void rent increases, trigger tenant claims for restitution, and expose landlords to civil penalties.

Frequently Asked Questions

Do single-family OC rentals need AB 1482 disclosure?
Yes. Even exempt single-family homes owned by natural persons must deliver a written exemption notice. Without it, the unit loses exempt status and falls under the cap.
What is the current rent cap?
Five percent plus regional CPI, capped at 10% total per twelve-month period. CPI varies by metro and is published annually by HCD.
