In California, from the sprawling urban areas of Los Angeles and San Diego to the tech hubs of San Jose and San Francisco, and further inland to Fresno and Sacramento, mold issues arise year-round. The state's diverse climate, featuring coastal fog, inland heat, and occasional heavy rains, creates varied environments where mold can establish itself.

California's housing stock includes a wide range of properties, from older, post-war homes to newer construction. Older buildings, especially those in coastal areas prone to fog or with less efficient ventilation, can be susceptible to moisture buildup. Inland areas experience high temperatures that can exacerbate humidity issues when combined with water intrusion. California's climate means mold growth is not strictly seasonal; it can occur whenever moisture is present, often following heavy rainfall or plumbing leaks.
