/// COMMON QUESTIONS · 15503 BLAINE AVE

The short answers.

Is 15503 Blaine 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 15503 Blaine Ave have?

County records list 4 units at 15503 Blaine Ave, classified as fourplex across 4,533 square feet of building area, averaging about 1,133 square feet per unit. Unit counts on the roll can lag permitted conversions and unpermitted additions in both directions.

When was 15503 Blaine Ave built?

The assessor roll gives a build year of 1977, 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 15503 Blaine Ave last change hands?

The most recent transfer on the roll was recorded December 2022. 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 15503 Blaine Ave assessed at, and is that what it is worth?

The current assessed value is $1,484,860 ($964,877 land, $519,983 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 15503 Blaine 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.
