How old they are.

Half the apartment parcels in 91604 Los Angeles were built in 1963 or earlier. 319 of 469, about 68%, went up in 1978 or before.

Across the 255 ZIP codes on this site that share is 89%, so 91604 Los Angeles has a smaller share of older buildings than the average. Older buildings tend to carry the questions a buyer will ask about, like plumbing, electrical, the roof and whether the building needs a seismic retrofit.

Rent control in 91604 Los Angeles.

469 of the 469 parcels in 91604 sit inside the City of Los Angeles by the city's zoning map. 319 of those were built in 1978 or earlier, and those are the buildings most likely to fall under the Los Angeles Rent Stabilization Ordinance.

That figure is worked out from the build year and the city line. It is not the Housing Department's own list, so check a single building on the LAHD lookup before you rely on it. Buildings in the city that the ordinance does not cover are often still under the state cap in AB 1482.

11 parcels here have an open soft-story retrofit permit on file with the city. That means a permit was pulled and the work had not been signed off when the city's data was read. It is not a list of every building that got an order.

How long owners hold.

The median Prop 13 base year for apartment parcels in 91604 Los Angeles is 2005. A base year resets when a building sells, so an old one usually means the same owner or the same family has held it a long time.

131 parcels, 28%, still carry a base year of 1995 or earlier. The figure for all 255 ZIP codes here is 28%, so owners in 91604 Los Angeles have held about as long as the average.

Long-held buildings often pay property tax on a value set decades ago. When they sell, the new owner is taxed on the price, which is part of why rents and expenses on these buildings need a close look before anyone sets a price.

How often buildings sell.

By last recorded transfer, 35 apartment parcels in 91604 Los Angeles changed hands in 2022, 17 in 2023 and 36 in 2024.

That is 7.7% of the parcels here, against 7.3% across all 255 ZIP codes, so buildings here turned over at about the same rate as the average.

A building that sold twice in those years shows up once, in its later year, and a transfer is not always a sale at market. A move into a trust or between family members is recorded too.

Inside the City of Los Angeles the Measure ULA transfer tax has applied to sales over about $5 million since April 2023. My study of how it changed sales is linked below.

Where these numbers come from.

  • Every count is from the 2025 Los Angeles County assessor roll and counts parcels the assessor lists with two or more units. A parcel can hold more than one building.
  • The sale years are the most recent recorded transfer on each parcel, through January 17, 2025. A transfer into a trust or between family members is recorded the same way as a sale.
  • The base year is the year Prop 13 last set the parcel's land value, which happens when it changes hands. Values set before 1975 show as 1975.
  • Rent control and soft-story figures cover the City of Los Angeles only and come from the city's zoning map and permit data. Rent control is worked out from the build year, not taken from the Housing Department's list.
