/// COMMON QUESTIONS · 3405 W 21ST ST

The short answers.

Is 3405 W 21st St rent controlled?

Built 1927 in the City of Los Angeles with 6 units — pre-October 1978 multifamily inside city limits is generally under the Rent Stabilization Ordinance, capping annual increases and restricting evictions. 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 3405 W 21st St have?

County records list 6 units at 3405 W 21st St, classified as 5+ units across 8,076 square feet of building area, averaging about 1,346 square feet per unit. Unit counts on the roll can lag permitted conversions and unpermitted additions in both directions.

When was 3405 W 21st St built?

The assessor roll gives a build year of 1927, which puts it in the pre-1979 stock that the LA Rent Stabilization Ordinance generally covers inside city limits. Age drives more than character here: it sets rent-cap exposure, seismic retrofit obligations, and what a lender will underwrite.

What is 3405 W 21st St assessed at, and is that what it is worth?

The current assessed value is $82,303 ($30,366 land, $51,937 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 — and this one has held its base year for roughly 51 years.

Would the owner of 3405 W 21st St face a big tax bill on a sale?

Possibly. A base year going back roughly 51 years usually means a low tax basis, and a low basis means a large taxable gain on a straight sale — capital gains plus depreciation recapture, with California taxing gains at ordinary income rates. It is also why long-held buildings so often sell through a 1031 exchange instead, or pass through an estate for the step-up in basis.

What is the Mid-City apartment market doing?

3405 W 21st 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 3405 W 21st 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.
