/// COMMON QUESTIONS · 10243 TOPANGA CANYON BLVD

The short answers.

Is 10243 Topanga Canyon Blvd rent controlled?

Built 2023 — 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 10243 Topanga Canyon Blvd have?

County records list 55 units at 10243 Topanga Canyon Blvd, classified as 5+ units across 29,041 square feet of building area, averaging about 528 square feet per unit. Unit counts on the roll can lag permitted conversions and unpermitted additions in both directions.

When was 10243 Topanga Canyon Blvd built?

The assessor roll gives a build year of 2023, 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 10243 Topanga Canyon Blvd last change hands?

The most recent transfer on the roll was recorded October 2019. 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 10243 Topanga Canyon Blvd assessed at, and is that what it is worth?

The current assessed value is $4,262,182 ($1,672,182 land, $2,590,000 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 10243 Topanga Canyon Blvd 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.
