State Laws and Rights

North Carolina mold law snapshot

North Carolina does not have a mold-specific statute, but habitability rules still apply.

North Carolina's implied warranty of habitability is codified under N.C.G.S. Section 42-42, which requires landlords to provide "fit premises." Landlords must comply with applicable building and housing codes materially affecting health and safety, make all repairs necessary to keep the premises in a fit and habitable condition, keep common areas safe, and maintain all electrical, plumbing, sanitary, heating, ventilating, air conditioning, and other facilities in good working order. The statute specifically addresses water-related issues that contribute to mold. Importantly, tenants cannot waive these rights - any lease provision releasing the landlord from these duties is void under N.C.G.S. 42-42(b).
