/// COMMON QUESTIONS · 10159 MOUNTAIR AVE

The short answers.

Is 10159 Mountair Ave 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 10159 Mountair Ave have?

County records list 1 unit at 10159 Mountair Ave, classified as duplex across 1,034 square feet of building area, averaging about 1,034 square feet per unit. Unit counts on the roll can lag permitted conversions and unpermitted additions in both directions.

When was 10159 Mountair Ave built?

The assessor roll gives a build year of 1921, 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 10159 Mountair Ave last sell, and for how much?

The last recorded transfer was August 2022, at an estimated $617,369 — about $617,369 per unit. That price is estimated from the Proposition 13 reassessment recorded at sale, not a verified closing price, so treat it as a close approximation rather than a confirmed figure.

What is 10159 Mountair Ave assessed at, and is that what it is worth?

The current assessed value is $642,311 ($443,156 land, $199,155 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.

How do I find out what 10159 Mountair Ave 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.
