Renting in Los Angeles: rent caps, just cause, and which rules cover your building

In Los Angeles the most important fact about your apartment is its birthday. Building age decides whether the city’s RSO, the state’s AB 1482, or neither caps your rent — and landlords are rarely eager to tell you which. Here’s how to work it out yourself.

The short answer

Two rulebooks might cap your rent in LA. Buildings first occupied before October 1978 (in the City of LA) generally fall under the city’s Rent Stabilization Ordinance — annually-set increase limits and strong eviction protections. Most other multifamily housing older than 15 years falls under statewide AB 1482: increases capped at 5% plus local inflation (never more than 10% total) and “just cause” required to end a tenancy after 12 months (Cal. Civ. Code §§ 1947.12, 1946.2). Statewide floors — the one-month deposit cap, 21-day return, 24-hour written entry notice — apply to everyone, everywhere in the state.

Which rulebook covers your building

LA rent law is a layer cake, and the layers are decided mostly by building age and ownership:

Your situationLikely rulebookWhat it means
City of LA multifamily, first occupied before Oct 1978LA RSOCity-set annual increase limit; strong eviction protections
Most other apartments 15+ years oldAB 1482 (state)5% + CPI cap (max 10%); just cause after 12 months
Single-family home owned by an individual, with the exemption noticeNeither capMarket increases; state floors still apply
Building under 15 years oldNeither cap (yet)Ages into AB 1482 at 15 years

Ten minutes of homework — the LAHD address lookup plus a look at your lease’s exemption language — settles which row you’re in. Don’t take the listing’s word for it.

AB 1482: the statewide cap most LA renters are under

What the law saysCal. Civ. Code § 1947.12
For covered housing, rent may not rise more than 5% plus regional CPI in any 12-month period — and never more than 10% total, whichever is lower, across at most two increases. Key exemptions: buildings under 15 years old; single-family homes and condos only when the owner isn’t a corporation, REIT, or corporate-member LLC and the tenant received the statutory exemption notice; owner-occupied duplexes; deed-restricted affordable housing.

The exemption-notice detail is the one to remember: a mom-and-pop single-family rental that never gave you the written exemption notice is covered, cap and all. Check your lease for that paragraph before accepting any big increase.

Just cause: ending your tenancy takes a reason

After 12 months in covered housing, a landlord needs stated just cause to terminate — at fault (nonpayment, material breach, nuisance) or no fault (owner move-in, withdrawal from the market, government order, substantial remodel). No-fault terminations owe you relocation assistance equal to one month’s rent (Cal. Civ. Code § 1946.2). The “substantial remodel” ground is LA’s most abused — a repaint and new countertops don’t qualify, and a termination notice that doesn’t state its cause is defective on its face.

What the law saysL.A. Mun. Code § 151.09
In the City of Los Angeles the local just-cause rule is often stronger than the state’s. RSO units are governed by L.A. Mun. Code § 151.09, and most other city rentals fall under the citywide Just Cause Ordinance (Chapter 165, in effect since January 27, 2023) — both require a stated legal reason to evict and relocation assistance for no-fault terminations. RSO rent increases are separately capped by the LAHD’s annual figure under § 151.06, well below the state cap.

The everywhere-rules: deposits, entry, screening

  • Deposits: one month’s rent max (small-landlord exception aside), 21-day itemized return — details in our CA deposit guide.
  • Entry: 24 hours’ written notice presumed reasonable, business hours, statutory purposes only (§ 1954).
  • Screening fees: capped (≈$60s in 2026, CPI-adjusted from $30), cost-based, itemized receipt required, refundable if no check is run (§ 1950.6).
  • Late fees: California has no safe-harbor percentage — a late fee must be a genuine estimate of hard-to-calculate actual damages or it’s an unenforceable penalty (§ 1671). Round-number fees “regardless of actual costs” are the tell.

LA quirks: ADUs, single-family homes, and “exempt” claims

LA’s backyard-ADU boom created thousands of new rentals with genuinely confusing status — an ADU is usually too new for RSO but may be covered by AB 1482 depending on age and ownership, and habitability law applies regardless of what the garage used to be. The recurring theme across all of it: “exempt” is a claim, not a fact. The lease language, the building’s birthday, and the owner’s corporate status decide — and every one of those is checkable.

Lease language to watch for
“Tenant acknowledges this property is exempt from all rent control and tenant protection laws, and waives any rights thereunder to the fullest extent permitted.”

Acknowledgments don’t create exemptions, and AB 1482’s protections can’t be waived by boilerplate. If the exemption is real, it exists with or without your signature; if it isn’t, this clause is decoration.

Questions renters ask

How do I find out if my building is under the LA RSO?

The city’s housing department (LAHD) runs a public lookup by address — RSO coverage generally means City of LA multifamily buildings with a certificate of occupancy before October 1, 1978. RSO status matters a lot: increase limits are set annually by the city and eviction protections are stronger than the state’s. If you’re in Santa Monica, West Hollywood, or another separate city, different local ordinances apply — check that city, not LA’s.

My landlord says the unit is “exempt from rent control.” Should I believe it?

Verify, don’t believe. For the state law, single-family homes and condos are exempt ONLY if the owner isn’t a corporation/REIT/corporate-LLC AND you were given the specific statutory exemption notice in writing — skip the notice, lose the exemption. New construction is exempt only for its first 15 years. And an AB 1482 exemption doesn’t touch RSO coverage if the building qualifies there. “Exempt” is a legal conclusion with paperwork attached; ask for the paperwork.

How much notice for a rent increase in LA?

State law requires written notice — and for increases above 10% (rare, since caps usually bite first), 90 days. Under AB 1482 the annual ceiling is 5% + regional CPI, hard-capped at 10%, measured over any 12-month window with at most the cap across two increases. RSO units follow the city’s annually-published percentage instead.

Can my landlord enter to show the unit whenever they want?

No — California requires written notice stating date, approximate time, and purpose, with 24 hours presumed reasonable, entries during normal business hours, and only for statutory purposes (Cal. Civ. Code § 1954). “Landlord may enter with or without notice” clauses are unenforceable.
