/// COMMON QUESTIONS · 3856 KEYSTONE AVE

The short answers.

Is 3856 Keystone Ave rent controlled?

Built 1922 in the City of Los Angeles with 3 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 3856 Keystone Ave have?

County records list 3 units at 3856 Keystone Ave, classified as triplex across 1,892 square feet of building area, averaging about 631 square feet per unit. Unit counts on the roll can lag permitted conversions and unpermitted additions in both directions.

When was 3856 Keystone Ave built?

The assessor roll gives a build year of 1922, 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.

When did 3856 Keystone Ave last change hands?

The most recent transfer on the roll was recorded January 2012. 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 3856 Keystone Ave assessed at, and is that what it is worth?

The current assessed value is $487,597 ($373,487 land, $114,110 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 27 years.

Would the owner of 3856 Keystone Ave face a big tax bill on a sale?

Possibly. A base year going back roughly 27 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.

How do I find out what 3856 Keystone Ave 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.
