/// COMMON QUESTIONS · 5506 THORNBURN ST

The short answers.

Is 5506 Thornburn St rent controlled?

Built 2022 — 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 5506 Thornburn St have?

County records list 12 units at 5506 Thornburn St, classified as 5+ units across 16,199 square feet of building area, averaging about 1,350 square feet per unit. Unit counts on the roll can lag permitted conversions and unpermitted additions in both directions.

When was 5506 Thornburn St built?

The assessor roll gives a build year of 2022, 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 5506 Thornburn St last change hands?

The most recent transfer on the roll was recorded April 2020. 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 5506 Thornburn St assessed at, and is that what it is worth?

The current assessed value is $4,980,314 ($1,365,393 land, $3,614,921 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 5506 Thornburn 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.
