Crawl Space Concerns in California

While the Southwest is dry most of the year, the combination of expansive soils and occasional heavy rain creates unique foundation challenges. Homes with crawl spaces benefit from proper drainage and vapor barriers, even in arid climates, to protect against monsoon moisture and soil gas.

!Expansive soils (bentonite clay) cause more foundation damage than any other natural hazard in the US
!Extreme heat dries soil unevenly, creating foundation settlement
!Monsoon season brings sudden water intrusion into otherwise dry crawl spaces
!Scorpions, spiders, and rodents seek shelter in cool crawl spaces
!Crawl spaces are less common here but homes that have them face unique challenges

Local Tip — California

Even in dry climates, a vapor barrier on the crawl space floor is recommended. It blocks soil gas (including radon), reduces dust, and prevents the rare but damaging moisture event from causing mold.
