State Laws and Rights

Louisiana mold law snapshot

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

Under Louisiana Civil Code Article 2691, landlords are bound to make all repairs necessary to maintain the rental property in a condition suitable for the purpose for which it was leased. This is known as the implied warranty of habitability. The landlord must provide a rental that is free of vices or defects that prevent its use as intended. This includes maintaining functional plumbing, heating and cooling systems, electrical systems, and addressing health hazards such as mold. This duty exists even if not mentioned in the lease agreement.
