/// COMMON QUESTIONS · 12577 ADELPHIA AVE

The short answers.

Is 12577 Adelphia Ave rent controlled?

Built 1952 in the City of Los Angeles with 2 units — pre-October 1978 multifamily inside city limits is generally under the Rent Stabilization Ordinance, capping annual increases and restricting evictions. 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 12577 Adelphia Ave have?

County records list 2 units at 12577 Adelphia Ave, classified as duplex across 2,350 square feet of building area, averaging about 1,175 square feet per unit. Unit counts on the roll can lag permitted conversions and unpermitted additions in both directions.

When was 12577 Adelphia Ave built?

The assessor roll gives a build year of 1952, 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 12577 Adelphia Ave last sell, and for how much?

The last recorded transfer was November 2024, at an estimated $284,607 — about $142,304 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 12577 Adelphia Ave assessed at, and is that what it is worth?

The current assessed value is $284,607 ($93,889 land, $190,718 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 12577 Adelphia 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.
