Tenant reported mold: California landlord guide
A tenant just told you there's mold. Here's the response sequence that protects the property and keeps you on the right side of habitability law.
- Acknowledge fast. Confirm receipt of the report in writing the same day, even before you've inspected anything.
- Inspect within a reasonable time. Schedule an inspection promptly to assess the extent and likely source of moisture.
- Document with photos. Photograph affected areas and note any visible damage or moisture readings.
- Assess the habitability implication. Evaluate whether the condition affects habitability under Civil Code §1941.1.
- Remediate the source, not just the surface. Fix the underlying leak or ventilation issue, and bring in a qualified remediation contractor for significant growth.
- Follow up in writing. Tell the tenant in writing what was found and what was done, with dates.

- How fast must a landlord respond to a mold report?
- There's no single fixed deadline, but you must act within a reasonable time — acknowledge quickly and inspect promptly.
- Is mold always a habitability issue?
- Not automatically — it depends on extent and cause, but significant mold tied to a moisture defect can implicate habitability duties.
- Should a landlord fix the mold or the moisture source?
- Both — remediating mold without fixing the underlying moisture source usually means it comes back.
