/// COMMON QUESTIONS · 12309 OSBORNE PL

The short answers.

Is 12309 Osborne Pl 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 12309 Osborne Pl have?

County records list 21 units at 12309 Osborne Pl, classified as 5+ units across 32,444 square feet of building area, averaging about 1,545 square feet per unit. Unit counts on the roll can lag permitted conversions and unpermitted additions in both directions.

When was 12309 Osborne Pl built?

The assessor roll gives a build year of 2006, which is after the October 1978 RSO cutoff. Age drives more than character here: it sets rent-cap exposure, seismic retrofit obligations, and what a lender will underwrite.

When did 12309 Osborne Pl last sell, and for how much?

The last recorded transfer was September 2020, at an estimated $8,725,997 — about $415,524 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 12309 Osborne Pl assessed at, and is that what it is worth?

The current assessed value is $9,445,300 ($3,777,687 land, $5,667,613 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 12309 Osborne Pl 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.
