What the buildings in Downey look like.

The average parcel here holds 7.4 units. 31 parcels hold 50 units or more. The largest ones are listed further down this page, each with its own public record.

How old they are.

Half the apartment parcels in Downey were built in 1955 or earlier. 1,855 of 2,044, about 91%, went up in 1978 or before.

Across the 255 ZIP codes on this site that share is 89%, so Downey has about the same share of older buildings as 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 Downey.

The City of Los Angeles rent ordinance does not cover Downey. 1,855 of the parcels here were built in 1978 or earlier, and age is usually the first thing a local rent rule looks at.

Where a city has no rent rule of its own, the state cap in AB 1482 covers most buildings more than 15 years old. Check with Downey before you underwrite a rent roll, because local rules change.

How long owners hold.

The median Prop 13 base year for apartment parcels in Downey is 2004. 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.

620 parcels, 30%, still carry a base year of 1995 or earlier. The figure for all 255 ZIP codes here is 28%, so owners in Downey 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, 126 apartment parcels in Downey changed hands in 2022, 109 in 2023 and 147 in 2024.

That is 7.2% 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.

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.
