/// COMMON QUESTIONS · 3667 KEYSTONE AVE

The short answers.

Is 3667 Keystone Ave 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 3667 Keystone Ave have?

County records list 49 units at 3667 Keystone Ave, classified as 5+ units across 42,777 square feet of building area, averaging about 873 square feet per unit. Unit counts on the roll can lag permitted conversions and unpermitted additions in both directions.

When was 3667 Keystone Ave 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 3667 Keystone Ave last change hands?

The most recent transfer on the roll was recorded August 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.

How do I find out what 3667 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.
