Mold Claims Are on the Rise: How to Protect Yourself as a California Landlord
One of the biggest trends we're watching in 2026 is the sharp increase in habitability lawsuits targeting mold in rental properties. Mold-related claims have been climbing steadily, and California's legal landscape makes landlords particularly vulnerable if they don't respond appropriately.
Why Mold Claims Are Increasing
California's climate, combined with aging housing stock and deferred maintenance in some properties, creates ideal conditions for mold growth. When tenants discover mold—or even suspect it based on musty odors or visible water damage—they now have access to more legal resources and attorneys willing to take these cases on a contingency basis.
The result is a significant uptick in claims, many of which result in substantial settlements or judgments against landlords who cannot demonstrate they took the problem seriously.
How to Protect Yourself
The single most important thing you can do is respond quickly to any tenant complaint about water intrusion, leaks, condensation, or musty odors. A fast response does two things: it mitigates the actual mold risk, and it creates a record showing you took the complaint seriously.
Beyond responding quickly, keep detailed records of every inspection, repair, and remediation effort. Photograph everything. Save all communications with tenants, contractors, and vendors. If a mold claim does arise, your documentation is your best defense.
Proactive Steps to Take Now
Schedule regular inspections of your properties, paying close attention to bathrooms, kitchens, laundry areas, and any spaces prone to moisture. Make sure your properties have adequate ventilation. Address any deferred maintenance that could contribute to water intrusion, such as aging roofs, deteriorating caulking, or poor drainage.
