Own an LA apartment building? Here’s everything you need to stay compliant and know what your building is worth — the RSO and rent-control rules, Measure ULA, AB 1482 and Costa-Hawkins, eviction and retrofit law, live market data, and the path to a real number when you’re ready to sell. All in one place, kept current.
Two living resources that map every law touching your building. Read these first, then dive into the specific rules below.
LA multifamily is one of the most regulated asset classes in American real estate.
The LA City Council passed an RSO rewrite on December 12, 2025.
The Rent Stabilization Ordinance is the single biggest factor in what you can charge, who you can move out, and what your building sells for.
The LA City Rent Stabilization Ordinance covers buildings within Los Angeles with a certificate of occupancy before October 1, 1978 and two or more units.
The LA County RSTPO covers residential rental properties in unincorporated LA County.
LA City RSO — Which Rent Control Rules Apply to Your Property? Most LA multifamily owners think "LA rent control" means one thing. It doesn't.
The LA City Rent Stabilization Ordinance (RSO) covers buildings within the City of Los Angeles with a certificate of occupancy dated before October 1…
LA City RSO caps your annual rent increases at 3% (through June 2026) or 4% (starting July 2026). For most landlords, those caps are absolute.
A hardship adjustment is a formal LAHD process allowing RSO landlords to apply for rent increases above the standard annual cap when current rents fail…
Primary renovation is a specific LA RSO pathway that allows landlords to undertake major work on rent-controlled buildings with tenant-notice and…

For LA City pre-1978 apartment buildings, proper RSO registration with the LA Housing Department (LAHD) is effectively required for a clean sale.
Rent control reduces your sale price. That's the honest sentence most broker websites avoid because it sounds like bad news for sellers. It's bad news.
Even buildings outside LA rent control answer to California statewide caps and exemptions. Know which set of rules applies to you.
AB 1482 is California's statewide rent cap and just-cause eviction law, enacted 2019. Current cap (Aug 2025–Jul 2026): 6.3% (5% + 1.3% CPI).
AB 1482 is California's statewide rent cap and just-cause eviction law, enacted in 2019 and still in effect.

LA’s "mansion tax" takes a percentage off the top of every sale over the threshold. Understand the bite before you list.

Measure ULA is an LA City transfer tax on real estate sales above a specified dollar threshold.

When and how you can move tenants out is tightly regulated — and getting it wrong is expensive. Here are the categories, costs, and your options.
Just-cause eviction rules require landlords to state a specific enumerated reason for ending a tenancy.
An at-fault eviction is based on tenant breach — non-payment, lease violation, nuisance, or similar.
A no-fault eviction terminates a tenancy for reasons unrelated to tenant behavior — owner move-in, substantial remodel, Ellis Act, or governmental order.
A tenant buyout is a voluntary cash-for-keys agreement where a tenant vacates in exchange for payment.
Under LA City relocation rules, a qualified tenant is a senior 62+, disabled, or a family with a minor child — entitled to higher relocation assistance…

Tenant buyouts are one of the most powerful exit tools available to LA multifamily sellers — and one of the most commonly executed incorrectly.
Relocation Assistance — Which Strategy When? LA RSO-covered landlords who need to vacate units have two primary tools: a voluntary buyout (tenant agrees…
The Ellis Act lets an LA landlord exit the rental business by withdrawing all units from the market. It is legal. It is mechanical.
Generally no — not for the purpose of selling at a higher price.
Under current LA City and California law, standard LA multifamily tenants do not have a generalized right of first refusal (ROFR) to purchase the…
Seismic retrofit deadlines, registration programs, and the enforcement systems that can hold up a sale if they’re not handled.

Once compliance is squared away, these walk through the mechanics of selling a rent-controlled, tenant-occupied LA building.
You sell a rent-controlled LA apartment building the same way you sell any LA apartment building — with tenants in place, rent roll documented…
Yes — and in LA multifamily, selling with tenants in place is the standard default.
A vacant unit in an LA apartment building is worth more than an occupied one.
Every owner of an LA building with a long-term tenant who runs a business in the unit, or a multi-generational family in a unit, or an heir who has been…
Your tenants' leases transfer to the new owner. Tenancies continue on the same terms. Rents stay where they are. Rent control protections stay intact.
Security deposits transfer with the building. They are not the seller's money to keep at close, and they are not the buyer's money to ignore.
Rent is prorated as of the closing date so each party — seller and buyer — keeps the rent attributable to the days they owned the building.
No, in most cases there is no formal legal obligation to notify tenants that you are selling.
Yes, but the lawsuit follows the building in ways most owners don't realize until they're at the negotiating table.
Most LA multifamily sales that go sideways go sideways for the same reasons. Not unusual reasons. Not market-driven reasons.
