/// COMMON QUESTIONS · 505 E COLUMBIA AVE

The short answers.

Is 505 E Columbia Ave rent controlled?

Outside LA RSO coverage on these records — most California multifamily over 15 years old falls under the AB 1482 statewide cap of 5% plus CPI, never more than 10% per year. 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 505 E Columbia Ave have?

County records list 4 units at 505 E Columbia Ave, classified as fourplex across 2,344 square feet of building area, averaging about 586 square feet per unit. Unit counts on the roll can lag permitted conversions and unpermitted additions in both directions.

When was 505 E Columbia Ave built?

The assessor roll gives a build year of 1939, 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 505 E Columbia Ave last change hands?

The most recent transfer on the roll was recorded October 2015. 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 505 E Columbia Ave assessed at, and is that what it is worth?

The current assessed value is $603,730 ($236,756 land, $366,974 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 10 years.

How do I find out what 505 E Columbia 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.
