/// COMMON QUESTIONS · 5550 BLACKWELDER ST

The short answers.

Is 5550 Blackwelder St rent controlled?

Built 2016 — 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 5550 Blackwelder St have?

County records list 2 units at 5550 Blackwelder St, classified as duplex across 3,170 square feet of building area, averaging about 1,585 square feet per unit. Unit counts on the roll can lag permitted conversions and unpermitted additions in both directions.

When was 5550 Blackwelder St built?

The assessor roll gives a build year of 2016, 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 5550 Blackwelder St last change hands?

The most recent transfer on the roll was recorded February 2017. 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 5550 Blackwelder St assessed at, and is that what it is worth?

The current assessed value is $1,363,684 ($928,467 land, $435,217 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.

What is the Mid-City apartment market doing?

5550 Blackwelder St sits in Mid-City, in Los Angeles. Recorded sale counts, median price per unit, median price per square foot, and the share of rent-control-era stock for the submarket are published and updated as the county roll refreshes — see the Mid-City market page for the current figures rather than a number quoted here.

How do I find out what 5550 Blackwelder 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.
