Lancaster housing

About 34 percent of Lancaster's roughly 55,000 homes were built before 1980, compared with about 70 percent across Los Angeles County, per the American Community Survey. Around 25 percent date from 2000 or later; the median year built is 1986.

For the older homes, have ceiling texture and flooring sampled before they come out, and test any paint from before 1978 for lead. Newer tracts tend to raise leak and indoor air questions instead.

High desert cold and heat

Lancaster's NOAA station averages January lows of about 31°F and July highs near 98°F, with about 7 inches of rain a year (1991-2020).

Nights that cold can freeze an exposed pipe or leave condensation in an attic. If a ceiling stains after a cold snap, moisture mapping can show whether a line leaked.

Antelope Valley AQMD

CARB places the northeast portion of Los Angeles County, which includes Lancaster, in the Antelope Valley AQMD. Asbestos survey and notice requirements for a demolition go through that district.

Questions

Can I get a mold test in a Lancaster rental?

Yes. Tenants or owners can request one; tell us who can let the partner in and where the problem shows.

Is a 1990s Lancaster house likely to have lead paint?

Unlikely, since residential lead paint was banned in 1978. A test settles it if you're unsure about older paint.
