/// COMMON QUESTIONS · 15910 LA FORGE ST

The short answers.

Is 15910 La Forge St rent controlled?

Outside LA RSO coverage on these records — most California multifamily over 15 years old falls under the AB 1482 statewide cap of 5% plus CPI, never more than 10% per year. This is an inference from public assessor records, not a determination — confirm the certificate of occupancy date with the LA Housing Department or ZIMAS before you rely on it for pricing or notices.

How many units does 15910 La Forge St have?

County records list 15 units at 15910 La Forge St, classified as 5+ units across 18,093 square feet of building area, averaging about 1,206 square feet per unit. Unit counts on the roll can lag permitted conversions and unpermitted additions in both directions.

When was 15910 La Forge St built?

The assessor roll gives a build year of 1961, which puts it in the pre-1979 stock that the LA Rent Stabilization Ordinance generally covers inside city limits. Age drives more than character here: it sets rent-cap exposure, seismic retrofit obligations, and what a lender will underwrite.

When did 15910 La Forge St last change hands?

The most recent transfer on the roll was recorded October 2023. Not every recorded transfer is a market sale — refinances, trust transfers, and family conveyances all appear in the same field, and those do not reset the assessed value.

What is 15910 La Forge St assessed at, and is that what it is worth?

The current assessed value is $2,157,400 ($333,844 land, $1,823,556 improvements). Assessed value is not market value. Under Proposition 13 it resets only on a change of ownership and then climbs about 2% a year, so a long-held building is often assessed far below what it would trade for — and this one has held its base year for roughly 39 years.

Would the owner of 15910 La Forge St face a big tax bill on a sale?

Possibly. A base year going back roughly 39 years usually means a low tax basis, and a low basis means a large taxable gain on a straight sale — capital gains plus depreciation recapture, with California taxing gains at ordinary income rates. It is also why long-held buildings so often sell through a 1031 exchange instead, or pass through an estate for the step-up in basis.

How do I find out what 15910 La Forge St would sell for today?

Public records give you the frame — units, size, age, assessed value, when it last traded — but pricing needs in-place rents, expenses, and the condition of the units, none of which appear in county data. A broker valuation puts closed comps and a rent survey against the actual rent roll. Shaya Lowenstein does that free for LA multifamily owners, typically within 48 hours, with no obligation to list.
