AB 1482: The Tenant Protection Act and Its Impacts on Tenants, Landlords, and the Broader Housing Market

For most of the decade before 2020, a California tenant outside a handful of older cities had no statutory ceiling on how much the rent could rise at renewal, and a landlord needed no stated reason to decline to renew. The Tenant Protection Act of 2019, enacted as Assembly Bill 1482 and signed into law in October 2019, changed both of those baselines at once. It capped annual increases on covered units and, separately, required a lawful, articulated reason — “just cause” — before many tenancies could be ended.

The statute is best understood not as rent control in the older sense but as a statewide floor: a minimum set of protections that applies almost everywhere residential housing is rented, while leaving stricter municipal ordinances untouched. It is codified in two operative sections of the Civil Code, carries a built-in expiration date, and turns on a set of exemptions that determine, unit by unit, whether the cap and the just-cause rule apply at all. The detail in those exemptions is where most disputes actually live.

What the rent cap actually limits

The rent cap is codified at California Civil Code section 1947.12. Over any 12-month period, an owner of covered residential real property may not increase the gross rental rate by more than 5 percent plus the percentage change in the cost of living, or 10 percent, whichever is lower. The 10 percent figure is a hard ceiling: even where regional inflation runs high, the combined increase cannot exceed it. No more than two increases are permitted in a 12-month period, and their combined effect is still bound by the same formula.

“Percentage change in the cost of living” is not a single statewide number. The statute ties it to the Consumer Price Index for All Urban Consumers for the metropolitan area in which the property sits, as published by the federal Bureau of Labor Statistics; where the Bureau publishes no figure for a region, the California CPI applies. In practice the relevant figure is the April-to-April change, applied to increases that take effect on or after August 1 each year. Because the regional component moves, the maximum lawful increase differs across the state and resets annually.

The just-cause requirement

The eviction half of the statute sits at Civil Code section 1946.2. Once a tenant has continuously occupied a covered unit for 12 months — or, where additional adult tenants are added, where at least one tenant has occupied it for 24 months — the owner may terminate the tenancy only for “just cause,” which must be stated in the termination notice. The section sorts just cause into two families with materially different consequences.

At-fault just cause

At-fault grounds turn on the tenant’s conduct: non-payment of rent, a material breach of the lease that is not cured after notice, maintaining a nuisance, committing waste, criminal activity on the premises, refusing to execute a substantially similar renewal lease, refusing the owner lawful entry, or using the unit for an unlawful purpose. For curable breaches, the owner must first give the tenant an opportunity to cure before proceeding to termination. The just-cause statute interlocks with ordinary unlawful-detainer procedure rather than replacing it, so the at-fault grounds substantially track the existing notice-and-cure scheme of Code of Civil Procedure section 1161, with the added requirement that the cause appear on the face of the notice. No relocation payment is owed when the ground is at-fault, and an owner is generally free to recover possession on a properly stated at-fault ground without the supply-of-assistance step that no-fault terminations require.

No-fault just cause and relocation assistance

No-fault grounds do not depend on tenant misconduct. They include the owner’s or a qualifying family member’s intent to occupy the unit, withdrawal of the property from the rental market under the Ellis Act, compliance with a governmental or court order to vacate, and intent to demolish or substantially remodel. Because the tenant has done nothing wrong, section 1946.2 requires the owner to assist with the move: one month’s rent, paid as direct relocation assistance within 15 calendar days of serving the notice, or waived by an equivalent reduction of the final month’s rent stated in the notice itself. Getting this step wrong has teeth — a notice that fails to provide or properly waive the payment is void.

Coverage and exemptions: which units are in

The cap and the just-cause rule share a similar but not identical set of carve-outs, and the exemptions do most of the practical sorting. The recurring categories are these.

New construction, on a rolling 15-year basis. Housing for which a certificate of occupancy was issued within the previous 15 years is exempt. The window rolls forward each year, so a building exempt today moves into coverage once it crosses the 15-year line. The statute pegs this exemption to a calendar that advances with time rather than to a fixed cutoff.

Single-family homes and condominiums — conditionally. A separately alienable single-family dwelling or condominium is exempt only if two things are true: the owner is not a real estate investment trust, a corporation, or an LLC in which at least one member is a corporation; and the owner has given the tenant the specific statutory notice of exemption. Without the written notice, the exemption is lost and the unit is treated as covered. The statute even prescribes the language of that notice.

Owner-occupied duplexes. A two-unit property is exempt from both the cap and just-cause when the owner occupies one of the units as a principal residence at the start of, and throughout, the tenancy. Deed-restricted affordable housing — units restricted by deed, regulatory agreement, or other recorded document to housing for households of very low, low, or moderate income — is likewise carved out, as is certain owner-occupied housing where the owner shares the dwelling and rents no more than two units or bedrooms, including accessory dwelling units. Dormitories and certain transient and institutional housing are excluded as well.

The rent cap, in numbers

How AB 1482 fits with local rent control and Costa-Hawkins

AB 1482 is a floor, not a ceiling on regulation. Where a city has its own rent-stabilization or just-cause ordinance that is more protective than the state statute — lower allowable increases, broader coverage, stricter eviction rules — the local law governs and AB 1482 recedes. Berkeley, Santa Monica, Los Angeles, San Francisco, and Oakland, among others, retain ordinances that bind more tightly than the statewide cap. The state law fills the gap for the much larger universe of units that no local ordinance reaches.

Sitting between the state floor and local control is the Costa-Hawkins Rental Housing Act of 1995, codified at Civil Code sections 1954.50 and following. Costa-Hawkins limits what cities may do: it guarantees vacancy decontrol (the right to reset rent to market on a new tenancy) and bars local rent control on single-family homes, condominiums, and units first occupied after February 1995. AB 1482 does not repeal Costa-Hawkins. The two coexist: Costa-Hawkins still constrains municipal ordinances, while AB 1482 imposes a separate statewide tenancy-duration cap that, critically, does not reach across vacancies — a new tenancy resets the rent.

Required notices

The statute runs on disclosure. A landlord relying on the single-family or condominium exemption must give the tenant the prescribed written notice; absent it, the unit is covered. For covered units, after July 2020, leases and renewals must contain a statutory notice informing the tenant that the property is subject to the Act’s rent-cap and just-cause provisions. And in any no-fault termination, the notice must both state the no-fault ground and provide or properly waive the relocation payment. Each of these is a condition the courts have enforced literally; a missing or misstated notice can be dispositive.

The practical weight of these requirements falls unevenly. For an institutional owner with standardized leases, the lease-level disclosures are a one-time drafting task. For the individual who rents out a single inherited house, the exemption notice is the entire difference between an exempt unit and a covered one, and it is the requirement most often overlooked. The asymmetry runs the other way at termination: there, the procedural burden of a valid no-fault notice — correct ground, timely relocation payment, exact statutory language — is where well-resourced owners have the advantage and unrepresented tenants frequently fail to spot a defective notice. The statute’s protections, in other words, are only as strong as the parties’ attention to its paperwork, which is one reason housing-clinic practice and tenant-counseling resources spend so much time on notice review.

The market debate: what the evidence does and does not say

Rent regulation is among the most studied questions in housing economics, and the findings cut in more than one direction. The most frequently cited recent work is Rebecca Diamond, Tim McQuade, and Franklin Qian’s study of San Francisco, published in the American Economic Review in 2019. Exploiting a 1994 ballot measure that extended rent control to small multifamily buildings, the authors found that covered tenants were roughly 20 percent less likely to move and were protected from displacement — but that landlords subject to the rules reduced rental supply by about 15 percent, converting and redeveloping units to escape regulation, and that the lost supply pushed up market rents for everyone else over the long run.

Economists nonetheless disagree about how much these results generalize, and the policy literature remains contested rather than settled. Critics of broad rent regulation point to supply and mobility costs; defenders point to displacement prevention and the value of predictability for incumbent tenants, particularly during sharp market spikes. AB 1482’s design — a high cap, vacancy reset, new-construction exemption — reads as an attempt to capture the anti-displacement benefit while limiting the supply distortion. Whether it threads that needle is an empirical question the statute is, in effect, still running.

Two features of the statute matter to that question in ways the headline numbers obscure. First, because the cap binds only within a tenancy and never across a vacancy, it leaves intact the strongest incentive a landlord has to remove an incumbent tenant in a rising market — the prospect of a market-rate reset on turnover. That is precisely the channel through which the San Francisco study traced supply loss, but AB 1482’s just-cause rule narrows the lawful routes to that reset, which is why the eviction half of the statute does analytical work the cap alone cannot. Second, the rolling new-construction exemption deliberately shields the marginal unit — the building a developer is deciding whether to start — from regulation for its first 15 years, an attempt to answer the standard objection that rent regulation chills new supply. Whether 15 years of exemption is enough to neutralize that effect is itself disputed, and no study of AB 1482’s own performance has yet settled it.

The sunset and the pressure to tighten

AB 1482 is not permanent. Both operative sections sunset on January 1, 2030, unless the Legislature extends them. That expiration date has become a focal point for reform efforts that would not merely renew the statute but tighten it. The most prominent recent vehicle was Assembly Bill 1157 (Kalra), introduced in 2025, which proposed to cut the cap to 2 percent plus CPI or 5 percent (whichever is lower), eliminate the single-family and condominium exemption, and strike the 2030 sunset to make the protections permanent.

AB 1157 stalled in the Assembly Judiciary Committee in 2025 and was pulled by its author, becoming a two-year bill; it remained inactive into 2026. Its failure to advance left the existing 5-percent-plus-CPI cap, the single-family exemption, and the 2030 sunset intact. But the bill signals the direction of legislative pressure, and the approaching sunset guarantees the Legislature will have to act on the statute one way or another before the decade closes.

Where this is heading is less a single question than a convergence of three. The first is renewal: the 2030 sunset forces a decision, and inaction means the statewide floor simply lapses. The second is scope: proposals like AB 1157 show a constituency for a lower cap and fewer exemptions, set against owners and industry groups who read the same San Francisco evidence as a warning about supply. The third is the interaction with cities, where stronger local ordinances continue to do the heavier lifting in the markets that need them most. For tenants and landlords alike, the practical takeaway is that the rules that look stable today carry an expiration date and an active reform debate behind them — and that the exemption notices, which decide coverage unit by unit, deserve closer attention than they usually get.
