How rent control changes what a Los Angeles building is worth

Under rent control a buyer is paying for today's rents plus a slow, capped rate of increase, with a reset to market only when a unit turns over for the right reason. That makes the rent roll you sell with, and the move-in dates on it, the core of the price.

Which rules apply to your building

The address and the certificate of occupancy date decide which rules a buyer is underwriting.

• City of Los Angeles, built on or before October 1, 1978. The Rent Stabilization Ordinance covers the rental units, including apartments, rented condos, duplexes and two or more houses on one parcel. A parcel with only one single-family home is exempt. LAHD's coverage page lists the categories, and its RSO property search looks up a specific property.
• City of Los Angeles, built later. The RSO does not apply. The City's Just Cause Ordinance covers most of these units once a tenant has lived there six months or the first lease has expired, whichever comes first, requires relocation assistance for no-fault evictions, and does not regulate rent. The statewide cap may limit increases.
• Unincorporated Los Angeles County. The County's Rent Stabilization and Tenant Protections Ordinance applies to rental units built before February 1, 1995 unless fully exempt, and limits annual increases on fully covered units. The County's rent increase page carries the current limit.
• Another city in the county. Check that city's own rules. A local ordinance can be stricter than the state cap, and where it is, the state cap does not apply.

Civil Code section 1954.52, part of the state's Costa-Hawkins law, lets an owner set the initial and all later rents for a unit whose certificate of occupancy was issued after February 1, 1995, or a unit that can be sold separately from any other, such as a condo. That is why units with a certificate of occupancy after February 1, 1995 sit outside local rent limits. The statewide cap in Civil Code section 1947.12 can still reach units that local rules do not.

How the RSO limits the income a buyer can count on

An RSO unit's rent can rise once a year by the allowable increase LAHD publishes. The City amended the formula effective February 2, 2026, to 90 percent of the average CPI, with a floor of 1 percent and a ceiling of 4 percent. The old formula had a 3 percent floor and an 8 percent ceiling. For July 1, 2026 through June 30, 2027 the allowable increase is 3 percent, according to LAHD's renter protections page. Two add-ons are also gone for increases on or after February 2, 2026: the additional percentage for landlord-paid utilities and the extra 10 percent for an additional occupant.

For value, the ceiling is the part that matters. A buyer modeling an occupied RSO unit can assume at most the allowable increase each year, and under the amended formula no year can exceed 4 percent. Income from a tenant who stays grows slowly, whatever inflation does, and a buyer prices that in.

LAHD's cost recovery programs let an owner apply to pass part of certain approved costs to tenants, such as up to half of a mandatory seismic retrofit. They recover money spent. They do not lift income above the formula.

The statewide cap on buildings the RSO does not cover

Civil Code section 1947.12, the statewide cap from AB 1482, limits increases over any 12-month period to 5 percent plus the change in the cost of living, or 10 percent, whichever is lower, measured from the lowest rent charged in the prior 12 months. It is in effect until January 1, 2030. AB 1157, which would have lowered the cap, failed in the Assembly Judiciary Committee on January 13, 2026. The Attorney General's rent cap page summarizes the rule.

Exemptions include housing under a stricter local rent control, housing with a certificate of occupancy issued within the previous 15 years, a single-family home or condo whose owner is not a REIT, a corporation or an LLC with a corporate member and whose tenant received the statutory written notice, and two units in a single structure where the owner has lived in one since the tenancy began and still does, as long as neither is an ADU or a junior ADU. For a buyer the difference is the ceiling. A building under the state cap can grow its income faster than an RSO building, so the same in-place rents support a different price.

Turnover and vacancy decontrol

Under the RSO, when a tenant leaves voluntarily or is evicted for nonpayment of lawful rent, the owner may set a new rent for the next tenant. After an owner or family occupancy eviction, the next tenant's rent is not decontrolled. Civil Code section 1954.53, part of Costa-Hawkins, sets the statewide version, letting an owner set the initial rent for a new tenancy, with exceptions that include a tenancy the owner ended by notice under section 1946.1.

That leaves a short list of ways an RSO unit reaches market rent, and none of them runs on the owner's schedule.

• A tenant moves out on their own. It happens when it happens.
• A buyout. LAHD defines a buyout agreement as a written agreement in which the landlord pays a tenant money or other consideration to move out voluntarily. The owner must give the tenant an RSO Disclosure Notice before signing and file the signed notice and agreement with LAHD within 60 days, and the tenant may cancel within 30 days of signing, according to the Tenant Buyout Notification Program. A buyout costs money and needs the tenant's consent.
• Owner or family move-in. The owner must hold at least 25 percent of the property to recover a unit for themselves, or 50 percent for a family member, occupy it as a primary residence for at least two consecutive years, file a Declaration of Intent to Evict with LAHD first, and pay relocation assistance. Tenants of ten or more years who are 62 or older or disabled, and terminally ill tenants, are protected from it. And it does not reset the rent for the next tenant.

A pro forma that assumes a set number of units reset each year is a guess about tenants' choices. Every eviction and buyout is also a legal process with its own notices and deadlines, and a mistake can cost more than the rent it was meant to recover.

Why in-place rents matter more under rent control

In a building without rent limits, a buyer who thinks rents are low can plan to bring them to market over a lease cycle or two. In an RSO building, the rent a tenant pays at closing grows by the allowable increase until that tenant leaves, which could be years. The rent roll you sell with is the income the buyer gets for a long time, and it is also what the buyer's lender counts. So the price leans on in-place rents, and projected rents earn less credit, for the reasons the page on cap rates and NOI gives.

The move-in dates change the picture as much as the rents. Two rent rolls with the same total can describe very different buildings. One has several long-term tenants far below market and a few recent ones near it. The other has every unit close to market. The first carries more upside and far less certainty about when it arrives. A GRM or price per unit borrowed from the wrong kind of building will misprice yours.

Shaya can read your rent roll the way a buyer will and show you which units drive the price and which ones carry the upside.

What a buyer of a rent-controlled building will ask for

• A rent roll with move-in dates and the date and amount of each tenant's last increase.
• Proof that the building's RSO registration is current and its fees are paid.
• Copies of rent increase notices, to check that increases stayed within the rules.
• Any buyout agreements filed with LAHD, and any owner move-in or other eviction history.
• Any open LAHD matters, such as a Tenant Habitability Plan for work in progress.
