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.
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.
