Santa Clarita housing age

The city's median build year is 1987, based on the American Community Survey, and about 29 percent of its roughly 78,000 homes are from 2000 or later. About 31 percent were built in 1979 or earlier.

For houses in that older group, test ceiling texture and flooring for asbestos before removal and check pre-1978 paint for lead. In newer homes, water intrusion and indoor air are the more frequent questions.

Dry summers in the valley

Average July highs reach about 94°F at NOAA's Newhall station, and yearly rain averages about 17 inches, with roughly 15 of them from November through March (1991-2020 normals).

February is the station's wettest month, and January nights average about 47°F. When a winter storm drives water under a door or into a crawl space, a partner can check for hidden moisture or sample suspected mold.

Air district boundaries

CARB places most of Los Angeles County in the South Coast AQMD, with the northeast portion in the Antelope Valley AQMD. Your contractor can confirm which district gets asbestos notices for a project at your address.

Yes. Let us know whether the concern is inside your unit or in a shared wall, since the association may need to be involved.

Do you cover the whole Santa Clarita Valley?

Send any address and we'll check which partners serve it. If nobody is active there, we'll tell you.
