Mold is a habitability violation under California Health and Safety Code §17920.3 and Civil Code 1941.1. A landlord who knows about mold and fails to remediate is violating the implied warranty of habitability.
What to Do Immediately
- Document with dated photos and video
- Send written notice by certified mail and email — describe location and extent
- Contact the local housing or building department — inspector’s report triggers the 180-day retaliation protection
- Keep records of health symptoms and any medical visits
If your landlord retaliates after you report mold — the 180-day presumption applies immediately. Document the timeline.
After written notice and reasonable time to repair: repair-and-deduct (up to one month’s rent), rent withholding, rent reduction, and damages for health impacts if documented by a physician.
Section 10 covers the habitability notice process with the Habitability Repair Notice letter template.
