State Laws and Rights

Mississippi mold law snapshot

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

Mississippi's implied warranty of habitability is codified in the Mississippi Residential Landlord and Tenant Act under Miss. Code Ann. Section 89-8-23. This section requires landlords to comply with the requirements of applicable building and housing codes materially affecting health and safety and to maintain the dwelling unit, its plumbing, heating, and/or cooling system in substantially the same condition as at the inception of the lease (reasonable wear and tear excluded). The warranty applies whether or not the lease agreement specifically states it and even if the lease attempts to waive the obligation. Rental properties must meet basic standards of safety and sanitation, including maintaining operational systems for electrical, plumbing, sanitation, heating, ventilating, and air conditioning.
