PROP 13 ASSESSED VALUES — USUALLY WELL BELOW MARKET ON LONG-HELD BUILDINGS.
No market sale detected on this parcel since 2021. The last recorded transfer may have been a refinance, trust move, or family transfer that didn't reset the Prop 13 base.
Built 1949 in the City of Los Angeles with 2 units — pre-October 1978 multifamily inside city limits is generally under the Rent Stabilization Ordinance, capping annual increases and restricting evictions.
PRICES ESTIMATED FROM ASSESSOR REASSESSMENT AT SALE (ASSESSED VALUE DEFLATED 2%/YR) — NOT VERIFIED CLOSING PRICES.
Built 1949 in the City of Los Angeles with 2 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.
County records list 2 units at 5409 Thornburn St, classified as duplex across 1,664 square feet of building area, averaging about 832 square feet per unit. Unit counts on the roll can lag permitted conversions and unpermitted additions in both directions.
The assessor roll gives a build year of 1949, 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.
The most recent transfer on the roll was recorded April 2021. 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.
The current assessed value is $822,057 ($480,737 land, $341,320 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 11 years.
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.
