State Laws and Rights

Michigan mold law snapshot

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

Michigan law establishes an implied warranty of habitability through MCL 554.139, which applies to every lease or license of residential premises. Under this law, landlords covenant that: (a) the premises and all common areas are fit for the use intended by the parties, and (b) they will keep the premises in reasonable repair during the term of the lease and comply with applicable health and safety laws of the state and local government. This warranty cannot be waived in leases shorter than one year. When mold growth results from a landlord's failure to maintain the property or address water intrusion, it may constitute a breach of this habitability covenant.
