/// COMMON QUESTIONS · 431 S ASPAN AVE

The short answers.

Is 431 S Aspan 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 431 S Aspan Ave have?

County records list 2 units at 431 S Aspan Ave, classified as duplex across 2,164 square feet of building area, averaging about 1,082 square feet per unit. Unit counts on the roll can lag permitted conversions and unpermitted additions in both directions.

When was 431 S Aspan Ave built?

The assessor roll gives a build year of 1947, 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 431 S Aspan Ave last sell, and for how much?

The last recorded transfer was June 2021, at an estimated $750,000 — about $375,000 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 431 S Aspan Ave assessed at, and is that what it is worth?

The current assessed value is $811,824 ($541,216 land, $270,608 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 431 S Aspan 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.
