Los Angeles RSO: Coverage, Rent Caps, and Evictions

The Los Angeles RSO, short for the Rent Stabilization Ordinance, is a city law that caps how much your rent can go up each year and requires your landlord to have a specific legal reason before evicting you. It covers roughly 650,000 rental units, and it applies to most apartments, duplexes, and condominiums in buildings that received their first certificate of occupancy on or before October 1, 1978. If your unit is covered, your landlord cannot raise rent freely, cannot decline to renew your lease without cause, and owes you money if they force you out for a reason that has nothing to do with your conduct.

What the RSO Is and Who It Covers

The ordinance was enacted in 1979 and turns primarily on one date. If the building received its first certificate of occupancy on or before October 1, 1978, the units inside are generally covered. Buildings that got a residential building permit on or before that date but received their certificate later are also covered.¹ Covered unit types include apartments, duplexes, condominiums, mobile homes, and recreational vehicles in mobile home parks.²

Some categories fall outside the ordinance. Hotels and motels are exempt unless a guest has stayed as a primary resident for more than 30 days, at which point the unit becomes RSO-covered. Government-operated housing, hospitals, and university dormitories are excluded. A luxury exemption exists for units that were rented above certain price thresholds, but the landlord must hold a certificate from the Los Angeles Housing Department to claim it.² State law also exempts single-family homes and condominiums with separately alienable titles under the Costa-Hawkins Rental Housing Act.

How to Check If Your Unit Is Covered

LAHD maintains a searchable database called ZIMAS (Zoning Information and Map Access System) where you can enter an address and find out whether the property is registered under the RSO. Another clue sits on your rent statement. Landlords are allowed to pass half of the annual RSO registration fee through to tenants as a surcharge, so a small RSO line item on your bill is a strong sign of coverage. If your landlord claims the unit is exempt, ask for documentation. A post-1978 exemption should be verifiable through the certificate of occupancy date, and a luxury exemption requires a certificate from LAHD.

How Much Rent Can Go Up Each Year

The allowable annual rent increase for RSO units effective July 1, 2025, through June 30, 2026, is 3%.³ The City Council recently amended the formula so that the cap is based on 90% of the average Consumer Price Index rather than 100%. Starting February 2, 2026, the annual increase will range from a floor of 1% to a ceiling of 4%, depending on the CPI. The same amendment eliminates the additional percentage landlords used to be able to add for paying utilities.⁴

Whatever the percentage, only one increase is allowed in any 12-month period. Your landlord must give at least 30 days’ written notice, and under state law, an increase over 10% requires at least 90 days’ notice. A landlord who raises rent more than once a year, skips notice, or exceeds the cap is exposed to treble damages.

Vacancy Decontrol Explained

This is the piece of the RSO most tenants misunderstand, and it shapes almost everything else. When a tenant leaves an RSO unit, the landlord can reset the rent to whatever the market will bear. The controlled rent leaves with the tenant, not with the unit. Once someone new moves in, the annual caps apply again on that new starting rent.

Vacancy decontrol is triggered when the tenant moves out voluntarily, is evicted for nonpayment, is evicted for a lease violation, is evicted for failing to comply with a Tenant Habitability Plan, is evicted by a City Attorney order, or accepts a buyout.⁵ The financial effect is significant. A long-term tenant may be paying $1,200 while an identical unit down the hall rents for $2,800. That gap is why landlords sometimes push hard to remove long-term tenants, and why the just-cause rules and buyout disclosure rules exist.

When a Landlord Can Evict You

A landlord cannot simply decline to renew your lease or ask you to leave. The RSO lists specific grounds, and the landlord must prove one of them applies. They divide into at-fault grounds, where the tenant did something wrong, and no-fault grounds, where the landlord has a legitimate reason unrelated to the tenant.⁶

The at-fault grounds are nonpayment of rent (but only where the amount owed exceeds one month of fair market rent as set by HUD for an equivalent-sized unit), a lease violation that the tenant fails to cure after written notice, nuisance or damage, illegal use of the unit, refusal to sign a renewal on similar terms after a written lease expires, refusal of reasonable access to the landlord, and an unapproved subtenant remaining at the end of a lease. Adding a first or second dependent child is not a valid basis for a lease-violation eviction, even if it pushes the unit over an occupancy limit in the lease.

No-fault grounds include owner or family member move-in, withdrawal of the entire building from the rental market under the Ellis Act, compliance with a government order to vacate, and primary renovation that requires the unit to be vacant. Every no-fault eviction triggers a mandatory relocation payment.

Owner Move-In Evictions

A landlord who wants the unit for personal use must hold legal title to at least 25% of the property and must intend to live there as a primary residence for at least two consecutive years. If the unit is for a family member (spouse, child, parent, grandparent, or grandchild), the ownership threshold rises to 50%.⁷ The landlord must actually move in within three months and stay two full years. Failing to do so is evidence of bad faith and opens the landlord to serious liability. The ground can only be used once per person in any rental complex the landlord owns, and it cannot be used at all if a vacant unit with the same number of bedrooms exists on the same property.

Some tenants cannot be evicted for owner move-in at all. A protected tenant is someone who has lived in the unit continuously for at least ten years and is either 62 or older, disabled, or terminally ill.⁷

Ellis Act Withdrawals

The Ellis Act is a state law that lets a landlord exit the rental business by withdrawing every unit in a building from the market. It is not a tool for removing one tenant. Tenants must receive at least 120 days’ notice. Tenants who have lived in the unit at least one year and are 62 or older or disabled are entitled to a full year’s notice.⁸ If the landlord re-rents the property within two years, the former tenant can sue for actual and punitive damages. If the building is demolished without following the Ellis Act procedures, any replacement units built on the same site become RSO-covered regardless of when they are constructed.

Relocation Assistance for No-Fault Evictions

Every no-fault eviction owes the tenant a relocation payment. The RSO uses two categories. A qualified tenant is someone who, on the date the notice is served, is 62 or older, disabled, or has at least one minor dependent child. Everyone else is an eligible tenant.⁹

The exact amount depends on the tenant’s category, length of tenancy, income, and whether the property qualifies as a small mom-and-pop building. For the period ending June 30, 2024, eligible tenant payments ranged from $9,500 to $12,950, and qualified tenant payments ranged from $19,150 to $24,650.¹⁰ Amounts are updated each July 1, so confirm the current figures with LAHD. The landlord must pay within 15 days of serving the eviction notice.⁶

Buyout Offers

Some landlords offer money to leave voluntarily instead of pursuing an eviction. The RSO regulates these deals closely because the pressure runs one way. Before making any offer, the landlord must give the tenant a written RSO Disclosure Notice explaining the tenant’s rights, and both parties must sign it before any offer is made.¹¹

The buyout agreement itself must be in writing, printed in the tenant’s primary language, and include a prominent statement in at least 12-point bold type telling the tenant they can cancel for any reason within 30 days of signing. If the landlord skips the disclosure or misses any of these requirements, the cancellation window extends through the entire statute of limitations period. A tenant harmed by a violation can sue for damages plus a $500 penalty. The landlord must file the disclosure and the signed agreement with LAHD within 60 days.¹¹

What You Can Do If the Landlord Violates the RSO

The ordinance carries real consequences. A landlord who charges rent above the lawful maximum is liable for three times the overcharge plus attorney fees and court costs.¹² Even a small monthly overcharge, tripled and compounded over years of tenancy, adds up.

A bad-faith owner move-in eviction, where the landlord never actually moves in or leaves before the two years are up, exposes the landlord to actual damages, punitive damages, and attorney fees, with damages tripled under the ordinance. Any RSO violation can also be prosecuted as a misdemeanor carrying up to $1,000 in fines or up to six months in jail.

Tenants can file complaints directly with LAHD through the department’s online complaint form. A housing investigator reviews the matter and can initiate enforcement.¹³ State law separately prohibits retaliation: a landlord cannot raise rent, cut services, or start an eviction within 180 days after you file a habitability complaint or exercise other legal rights. Threatening to report a tenant to immigration authorities also counts as retaliation.¹⁴

If Your Unit Isn’t Covered by the RSO

Post-1978 apartments and other units outside the RSO may still be protected by the California Tenant Protection Act (AB 1482). That statewide law caps annual rent increases at 5% plus the local Consumer Price Index, or 10%, whichever is lower, and requires just cause for eviction in most rental housing after 12 months of tenancy.¹⁵

AB 1482 does not apply to units already covered by a local rent control ordinance with a lower cap, so RSO tenants are governed entirely by the local rules. Owner-occupied duplexes and single-family homes owned by natural persons (not corporations or REITs) who provide the required written notice are also exempt from AB 1482.¹⁵
