State Laws and Rights
Nevada mold law snapshot
Nevada does not have a mold-specific statute, but habitability rules still apply.
Under NRS 118A.290, landlords must maintain rental units in habitable condition at all times during the tenancy. A dwelling unit is not habitable if it violates provisions of housing or health codes concerning health, safety, sanitation, or fitness for habitation. The statute requires landlords to provide: effective waterproofing and weather protection of the roof and exterior walls (including windows and doors), plumbing facilities in good working order, a water supply capable of producing hot and cold running water, adequate heating facilities, electrical systems maintained in good working order, and sanitary conditions. These requirements cannot be waived by tenants in the rental agreement.
