California Rent Increase Rules for Landlords

Overview of AB 1482 Rent Caps

The California Tenant Protection Act of 2019, commonly known as AB 1482, established statewide rent caps for most residential rental properties. Under Civil Code Section 1947.12, landlords may not increase rent by more than 5% plus the percentage change in the regional Consumer Price Index (CPI), or 10% of the lowest gross rental rate charged at any point during the 12 months before the effective date of the increase, whichever is lower. This effectively limits most annual rent increases to between 5% and 10%.

The rent cap applies on a rolling 12-month basis. Landlords cannot circumvent the cap by implementing multiple smaller increases that together exceed the annual maximum. Each rent increase must be evaluated against the total of all increases implemented in the preceding 12-month period. The cap applies to the gross rental rate, meaning it includes all charges designated as rent regardless of how they are labeled.

AB 1482 was originally set to expire on January 1, 2030, but subsequent legislation may extend or modify these provisions. Landlords must stay current with legislative developments to ensure ongoing compliance. The law does not prohibit landlords from banking unused increases; if a landlord does not raise rent in a given year, they cannot combine two years of allowable increases into a single larger increase the following year.

Exemptions from the Rent Cap

Several categories of rental properties are exempt from AB 1482's rent cap provisions. Single-family homes and condominiums are exempt if they are not owned by a corporation, real estate investment trust, or LLC with at least one corporate member, and the owner provides written notice of the exemption to the tenant. Properties built within the last 15 years are exempt based on their certificate of occupancy date.

Owner-occupied duplexes where the owner lives in one of the two units are exempt from both the rent cap and just cause eviction requirements. Housing that is already subject to a local rent control ordinance that restricts rent increases to less than the AB 1482 cap is exempt from the state cap, though the local ordinance continues to apply. Affordable housing units restricted by deed, regulatory agreement, or other recorded document are also exempt.

Landlords claiming an exemption must provide written notice to tenants. For the single-family home and condo exemption, the notice must be provided in the lease or as a standalone document. Failure to provide the required notice means the exemption does not apply, even if the property would otherwise qualify. The notice requirement ensures tenants are informed of their rights and the basis for any claimed exemption.

Just Cause Eviction Under AB 1482

AB 1482 also established just cause eviction protections for tenants who have occupied a unit for at least 12 months. Under Civil Code Section 1946.2, landlords of covered properties cannot terminate a tenancy without specifying a legally valid reason. Just cause is divided into at-fault causes, where the tenant has done something wrong, and no-fault causes, where the landlord has a legitimate business reason unrelated to tenant behavior.

At-fault just causes include nonpayment of rent after written notice, material breach of the lease, maintaining a nuisance, criminal activity on the premises, refusal to allow lawful entry after proper notice, subletting in violation of the lease, refusal to sign a lease renewal on substantially similar terms, and failure to vacate after the lease term expires following proper notice. The landlord must document the at-fault behavior and provide appropriate notice before terminating.

No-fault just causes include the owner or their immediate family member moving into the unit, withdrawal of the unit from the rental market under the Ellis Act, compliance with a government order requiring vacancy, and intent to demolish or substantially renovate the unit. For no-fault terminations, landlords must provide 60-day written notice and pay relocation assistance equal to one month's rent directly to the tenant. Failure to provide relocation assistance renders the termination void.

Compliance Strategies for Landlords

California landlords subject to AB 1482 should implement systematic rent tracking to ensure compliance with the annual cap. Maintain records of every rent increase including the effective date, the percentage increase, and the applicable CPI rate used in the calculation. These records are essential evidence if a tenant challenges an increase as exceeding the statutory maximum.

Proper notice procedures are critical. California requires 30 days written notice for rent increases of 10% or less within any 12-month period, and 90 days written notice for increases exceeding 10%. Since AB 1482 caps increases below 10%, the 30-day notice requirement typically applies for AB 1482-covered properties. However, if the total of all increases in the past 12 months exceeds 10%, the 90-day notice requirement is triggered.

Landlords operating in cities with local rent control ordinances face dual compliance requirements. Local ordinances in San Francisco, Los Angeles, Berkeley, Oakland, East Palo Alto, and other cities may impose lower rent caps and additional procedural requirements such as annual registration, mandatory mediation, and capital improvement pass-throughs. The more restrictive provision applies in each case, so landlords must be familiar with both state and local requirements.
