Who is responsible for mold in a rental?
Updated By the Housing Rocket moderators
Short answer
The landlord is usually responsible when mold comes from a leak, a building defect or inadequate ventilation. You may be responsible for small surface mold caused by everyday moisture you can control, like not running the bathroom fan or drying laundry indoors. Report any mold in writing quickly, because hidden leaks get worse over time.
Small spots on shower caulk or a window frame can usually be cleaned with a household mold cleaner. Larger patches, growth that keeps coming back, a musty smell, or mold on walls and ceilings point to a moisture source the landlord needs to find and fix.
- Photograph the mold and note where it is and how large.
- Send a written repair request and ask what is causing it.
- Cut down moisture in the meantime: run fans, open windows when you can, and wipe condensation.
- If nothing happens, request a code inspection from your city or county.
If mold seems to be making someone in the household sick, see a doctor and keep the records. Some states have specific mold rules or disclosure requirements, and in serious cases tenants may be able to end the lease. Renters insurance often excludes mold damage, so move belongings away from affected areas.
