California Tenant Protection Act (AB 1482): Rent Control and Exemptions Explained

The California Tenant Protection Act of 2019 — universally known as AB 1482 — is the law that California real estate investors spend the most time getting wrong. Not because it's impossibly complex, but because the exemptions require precise execution to be valid, and the penalty for botching the exemption process is severe: retroactive rent rollbacks, relocation assistance obligations, and liability for attorney fees in lawsuits that tenants are effectively incentivized to file.

Understanding AB 1482 is not optional if you own or are considering buying California rental property. It is the framework that determines what rents you can charge, when you can terminate a tenancy, and what it costs you when you get it wrong.

What AB 1482 Does

AB 1482 imposes two distinct obligations on covered properties:

1. Annual rent caps. Covered landlords cannot increase rent by more than 5% plus the regional CPI, or a maximum of 10%, whichever is lower. The applicable CPI is determined by region and changes every August 1.

2. Just cause eviction. Once a tenant has lived in a covered unit for 12 months — or at least one tenant on the lease has lived there for 24 months — the landlord cannot terminate the tenancy without a legally recognized "just cause" reason. For no-fault evictions, the landlord must also pay the tenant one month's rent as relocation assistance.

Both protections operate simultaneously. The rent cap limits how quickly you can grow income; the just-cause requirement limits how quickly you can remove non-paying or problematic tenants.

Current Rent Cap Rates by County (August 2025 – July 2026)

The CPI figure used is the regional change in the All Items Urban Consumer Price Index for the 12 months ending April of the prior year. Here are the current applicable caps:

Notice periods: 30 days written notice for increases of 10% or less; 90 days for increases above 10% (though with the 10% absolute cap, 90-day notice would only apply to stacked increases from multiple periods).

Properties Exempt from AB 1482

AB 1482 does not apply to all California residential rental properties. The major exemptions:

New construction (rolling 15-year exemption). A property with a certificate of occupancy issued within the past 15 years is exempt from both the rent cap and the just-cause requirement. The 15-year window rolls forward annually — a property built in 2010 was exempt until 2025, and is now covered as of 2026. Investors targeting new construction should track this date carefully in their underwriting.

Single-family homes and condos owned by individuals or qualifying LLCs. A separately alienable unit (SFH or condo) is exempt if it is owned by a natural person or an LLC where all members are natural persons (no corporate members). REITs, corporations, or LLCs containing a corporation as a member do not qualify for this exemption.

Owner-occupied duplexes. If the owner lives in one unit of a duplex, the other unit is exempt.

Other exemptions. Affordable housing developments subject to deed restrictions providing lower-than-market rents, certain mobile homes, dormitories, and single-room occupancy (SRO) units have varying exemption rules.

The Critical Notice Requirement — Where Landlords Lose Their Exemption

This is the most consequential and most commonly mishandled aspect of AB 1482. Even if your property meets all the criteria for a SFH/condo exemption — you are an individual owner, the unit is a free-standing house, it's been more than 15 years since construction — the exemption is not automatic. You must affirmatively provide the tenant with written notice of the exemption in the exact language specified by California Civil Code §1946.2(e).

The required notice states, in substance, that the property is not subject to the just cause requirements of Civil Code §1946.2 or the rent limitation provisions of Civil Code §1947.12, because the property qualifies as a single-family residence or condo under the specified ownership criteria.

If this notice is not provided:

• The exemption is voided entirely, regardless of whether the property otherwise qualifies
• The property becomes subject to AB 1482 rent caps retroactively
• Any rent increases charged above the AB 1482 cap during the period without proper notice may need to be refunded
• Any eviction attempted without just cause during this period is invalid
• The landlord may be liable for civil penalties, tenant attorney fees, and statutory damages

This is not a minor procedural requirement. Courts have consistently held that the notice obligation is strict. Landlords who discover after the fact that they never served the exemption notice often face choices between absorbing a rent reduction, paying a buyout, or litigating — all expensive.

When to serve the notice: At the inception of any tenancy, include the exemption notice in the lease documents. For existing tenants, serve it as soon as you discover it's missing — though serving it late does not cure any past period during which rent increases may have been non-compliant.

How AB 1482 Interacts with Local Rent Control

AB 1482 is a floor, not a ceiling. Local municipalities can enact stricter rent control and eviction protections, and when they do, local law governs.

Key local systems that supersede AB 1482 for covered units:

• San Francisco: Rent Stabilization Ordinance applies to most units in buildings built before June 13, 1979, with rent increases limited to 60% of CPI (approximately 1.3% for 2025-2026)
• Los Angeles City: Rent Stabilization Ordinance (RSO) covers buildings built before October 1, 1978. Allowable RSO increase is 75% of local CPI (roughly 2.25% for 2025-2026)
• Berkeley: Covers most rentals built before 1980, with increases tied to the Rent Board's annual determination
• Santa Monica, West Hollywood, Oakland, San Jose: All maintain independent rent ordinances stricter than the AB 1482 state cap

An investor in Oakland with a 1975 duplex is operating under Oakland's municipal rent control, not the AB 1482 state cap. The two systems do not stack — local law applies.

Proposition 33: What It Would Have Changed

In November 2024, California voters rejected Proposition 33, which would have repealed the Costa-Hawkins Rental Housing Act and allowed cities to impose rent control on single-family homes, new construction, and all other previously exempt properties. The proposition failed 60.02% to 39.98% — the third time a similar measure failed in six years.

The defeat was significant, but the margin narrowed from the 2018 and 2020 defeats. Investors in California must underwrite the perpetual risk that rent control expansion will eventually pass in some form. The most defensible hedge is to target new construction (maintaining the rolling 15-year exemption) or to own properties in jurisdictions without strong local rent control ordinances.

What This Means for Acquisition Strategy

AB 1482's framework shapes which properties are worth buying in California:

New construction is premium for a reason. Post-2011 construction (currently exempt through 2026) commands higher prices precisely because buyers are paying for the 15-year exemption window — the ability to raise rents to market without restriction during the most critical cash-flow years.

SFH exemptions only work if properly documented. Single-family homes offer AB 1482 exemption, but only with proper notice and only for individual/qualifying LLC owners. This makes the ownership structure a variable in the business case for SFH rentals.

Multi-family pre-1979 buildings in rent-controlled cities require special underwriting. Expected rent growth must be modeled at the local ordinance cap, not market rate. The exit value depends heavily on the relationship between rent levels, cap rates, and what a future buyer is willing to pay for a rent-controlled income stream.

The California Investment Property Guide includes an AB 1482 exemption flowchart, county-by-county rent cap tables, the exact statutory notice language required under Civil Code §1946.2, and an underwriting model that correctly applies local versus state rent caps for major California markets — so your projections reflect what you can actually charge, not what you might assume.

The Bottom Line

AB 1482 is manageable if you understand it. The exemptions are real and valuable, but they require affirmative execution — you can't just assume your property is exempt and act accordingly. Document the notice, serve it correctly, and model your rent growth assumptions within the applicable cap. California's rent control framework rewards landlords who know the rules and penalizes those who don't.
