/// COMMON QUESTIONS · 4319 SAINT MARK AVE

The short answers.

Is 4319 Saint Mark 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 4319 Saint Mark Ave have?

County records list 2 units at 4319 Saint Mark Ave, classified as duplex across 3,548 square feet of building area, averaging about 1,774 square feet per unit. Unit counts on the roll can lag permitted conversions and unpermitted additions in both directions.

When was 4319 Saint Mark Ave built?

The assessor roll gives a build year of 1955, 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 4319 Saint Mark Ave last change hands?

The most recent transfer on the roll was recorded June 2018. 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 4319 Saint Mark Ave assessed at, and is that what it is worth?

The current assessed value is $1,029,732 ($688,385 land, $341,347 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.

How do I find out what 4319 Saint Mark 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.
