Mold, Leaks & Maintenance Neglect
Mold and water leaks are the most legally serious maintenance issues because they create health risks and uninhabitable-unit claims. Document EVERYTHING in writing — these are the cases where renters win meaningful damages, but only with a paper trail.
Signs You Have This Problem
- • Black or green spots on bathroom walls / ceiling
- • Musty smell that returns after cleaning
- • Persistent unexplained respiratory symptoms
- • Water stains on ceiling under upstairs bathroom
- • Peeling paint near windows or pipes
Common Causes
- • Hidden roof or pipe leaks
- • Inadequate bathroom ventilation (no exhaust fan)
- • Old buildings with poor moisture barriers
- • Landlord deferred maintenance
- • Window condensation in winter
Immediate Solutions
- • Report in writing IMMEDIATELY (email + dated text) — creates legal record
- • Take photos of every patch + the moisture source if visible
- • Request a written response with repair timeline
- • For black mold (Stachybotrys): demand professional remediation, not just paint-over
- • Run a dehumidifier as interim measure to keep humidity below 50%
Prevention
- • Run the bathroom fan during AND for 30 min after every shower
- • Squeegee shower walls weekly
- • Open windows for cross-ventilation 15 min daily
- • Report any leak within 24 hours (mold grows in 48-72 hours on wet drywall)
- • Inspect under sinks monthly for slow drips
When to Escalate
If landlord fails to remediate mold within 14 days of written notice, contact your city housing inspector. In severe cases (visible black mold, respiratory illness), you may have grounds for "constructive eviction" — legally breaking the lease without penalty due to uninhabitable conditions. Consult a tenant-rights attorney first.
