State Laws and Rights

Arkansas mold law snapshot

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

Arkansas does not have a traditional implied warranty of habitability. However, for leases entered into or renewed after November 1, 2021, Arkansas Code Section 18-17-502 requires landlords to provide certain implied residential quality standards including: hot and cold running water, electricity, potable drinking water, sanitary sewer and plumbing conforming to applicable codes, a functioning roof and building envelope, and functioning heating and air conditioning. These standards are more limited than the full habitability warranties found in other states, and notably, all landlord responsibilities can be waived by written agreement with the tenant.
