State Laws and Rights

Kentucky mold law snapshot

Kentucky has mold-specific rules in addition to general habitability standards.

In jurisdictions that have adopted URLTA, landlords must comply with building and housing codes affecting health and safety, make all repairs necessary to keep the premises fit and habitable, keep common areas clean and safe, maintain all electrical, plumbing, sanitary, heating, ventilating, and air conditioning systems in good working order, and supply running water, hot water, and reasonable heat (October 1 through May 1). Outside URLTA jurisdictions, there is no implied warranty of habitability, and landlords only owe duties specified in the lease agreement. While mold is not specifically addressed, conditions that create mold growth (such as leaks or inadequate ventilation) may violate habitability standards if they materially affect health and safety.
