What raises or lowers an apartment building's value

A buyer's price moves when something changes the income the buyer can count on, the money the buyer will have to spend after closing, or how certain either one is. This page takes the factors that come up on Los Angeles apartment buildings and says which way each one pushes, and why. It gives no dollar figures for any of them, because the size of each effect depends on the building and the sales around it.

Income: rents, vacancy and who pays the utilities

Rents compared with market

The rents tenants pay today set the in-place net operating income, and that is what a buyer's lender counts. Rents below market therefore lower the value on today's numbers. They can also raise what a buyer will pay above that level, if the buyer expects to close the gap when units turn over. How much credit the gap earns depends on whether the rules let rents reset and how often units actually turn. Rents above market push the other way. A buyer who thinks a unit would re-rent for less if the tenant left will not pay full value for that rent.

Vacancy

An empty unit cuts the income a lender counts and makes a buyer ask why it is empty. A history of high vacancy lowers value more than a single turnover does, because it suggests a problem with the building, the location or the rents. Under rent control a vacant unit also has a second side. In the City of Los Angeles, when a tenant leaves voluntarily or is evicted for nonpayment of rent, the owner may set a new rent for the next tenant, so a buyer can price that unit at market. A unit emptied through an owner or family occupancy eviction does not reset for the next tenant.

Who pays the utilities

Utilities the owner pays are an operating expense, so they lower NOI and the value built on it. A building where each unit has its own gas and electric meter keeps those costs with the tenants. A building on shared meters puts them on the owner, and converting to separate meters is a capital project a buyer will weigh against the savings. Under the Los Angeles Rent Stabilization Ordinance, increases on or after February 2, 2026 no longer carry an additional percentage for landlord-paid utilities, according to LAHD's summary of the amended formula. An owner who pays utilities in an RSO building now absorbs rising utility costs without that added increase.

Billing existing tenants for utilities that their rent used to cover is a legal question under rent control, and a buyer should not count on it without advice. Ask a landlord-tenant attorney or LAHD before building it into a price. Shaya Lowenstein is a real estate agent, not an attorney, and cannot answer it for you.

The building: unit mix, parking and deferred maintenance

Unit mix

The mix of studios, one-bedrooms and larger units decides how much rent each unit can bring in, who rents there and how quickly an empty unit fills. A mix that matches what renters nearby look for supports value. An unusual one narrows the pool of tenants and the pool of comparable sales. The mix also changes how the building reads on a price per unit basis, since that measure counts a studio and a three-bedroom the same. The page on GRM and price per unit covers that trap.

Parking

Parking can earn income on its own and makes units easier to rent where renters rely on cars, so having it pushes value up and lacking it pushes value down. Its form matters too. Open parking under the upper floors of an older wood-frame building is one of the conditions the City's soft-story program targets, below.

Deferred maintenance

Work the building needs and has not had comes off the price, because the buyer inherits it. A buyer subtracts the expected cost and may add a margin for what an inspection cannot see, such as plumbing inside the walls. Documented recent work pushes the other way, since it removes both the cost and the doubt. Work done without permits can cut value instead of adding it, because a buyer may have to legalize or undo it.

Soft-story retrofit status

The City of Los Angeles runs a mandatory soft-story retrofit program under Ordinance 183893. LADBS describes the target buildings as two or more stories of wood-frame construction, built under building codes enacted before January 1, 1978, with ground-floor parking or other similar open floor space. The program does not apply to residential buildings of three or fewer units.

If your building is covered, its status moves the price. A finished retrofit with a final permit sign-off removes a cost and an unknown, which supports value. Work that has not started or is unfinished comes off the price, because the buyer takes on the engineering, the construction, the disruption to tenants and the risk of surprises.

For a building under the RSO, part of that cost can come back from tenants, within limits. LAHD's Seismic Retrofit Work Program says the City limits the share of mandatory seismic retrofit costs an owner can pass to tenants to 50 percent of the total, the pass-through needs LAHD approval, and the owner must first complete the Tenant Habitability Program requirements. A buyer should assume at least half the cost stays with the owner.

Zoning and development upside

Zoning decides how many units a lot could hold. When an older building sits on a lot zoned for far more than it has, a developer may value the site above what the building's income supports, which pushes value up. The City's ZIMAS map shows a parcel's zoning, and it also shows whether the property is in a local historic district, where projects face additional review.

Several rules shrink that premium. Under the state Housing Crisis Act and the City's rules that carry it out, a housing project that demolishes units has to replace them, with affordability and size requirements, unless they have been vacant for more than five years. City Planning's fact sheet on replacement requirements counts a unit that was subject to the RSO in the last five years as a protected unit. Existing occupants can stay until six months before construction starts, and lower income tenants have a right to return to a unit in the new building. Each of those lowers what a developer can net from the site, adds time before building can start, and so lowers what the developer can pay you.

Development upside is an option, not income. It is worth something only to a buyer who wants to use it, and that buyer will price in the entitlement time, the replacement units and the tenant protections before offering anything for it.

Rent control

Rent control lowers the growth a buyer can plan on, which lowers what the buyer will pay for a given level of today's income compared with an otherwise identical building without it. In the City of Los Angeles, the RSO covers rental units whose certificate of occupancy was issued on or before October 1, 1978. For July 1, 2026 through June 30, 2027, the allowable increase on those units is 3 percent, under a formula of 90 percent of average CPI with a floor of 1 percent and a ceiling of 4 percent that took effect February 2, 2026. A building outside the RSO may fall under the statewide rent cap instead, unless an exemption applies.

Rent control also changes which of the factors above matter most. Turnover becomes the main way income resets, the move-in dates on the rent roll become as important as the rents, and a vacant unit becomes worth more than its missing rent suggests. The page on how rent control changes value works through those effects in detail.
