/// COMMON QUESTIONS · 21925 DE LA OSA ST

The short answers.

Is 21925 De La Osa St rent controlled?

Built 2018 — buildings under 15 years old are exempt from AB 1482; the state cap applies once the building turns 15. 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 21925 De La Osa St have?

County records list 2 units at 21925 De La Osa St, classified as duplex across 3,750 square feet of building area, averaging about 1,875 square feet per unit. Unit counts on the roll can lag permitted conversions and unpermitted additions in both directions.

When was 21925 De La Osa St built?

The assessor roll gives a build year of 2018, 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 21925 De La Osa St last sell, and for how much?

The last recorded transfer was December 2021, at an estimated $2,099,999 — about $1,050,000 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 21925 De La Osa St assessed at, and is that what it is worth?

The current assessed value is $2,228,536 ($265,302 land, $1,963,234 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 21925 De La Osa St 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.
