In 2003, Montana passed The Mold Disclosure Act. Under the law, a seller or landlord is required to disclose the presence of mold, if they know of such a problem. The seller or landlord must provide a written mold disclosure statement when they are offering to sell or rent you a house or apartment.
Montana law instructs that sellers and landlords must disclose whether a building has been tested for mold. The seller or landlord is then required to disclose the results of all mold tests and the results of all remediation efforts they took to fix the problem. Thus, if mold had ever been present but had since been removed, there must be documentation under the Mold Disclosure Act, and any landlord or seller would be required to disclosure that information.
It is a tenants responsibility as a renter to maintain the property and to keep it in a clean and sanitary condition. Running fans, vacuuming your carpets, and reporting any problems to a landlord in a prompt and timely manner will help prevent property damage and health problems.
A Montana landlord-tenant lawyer will be able to guide you through the numerous legalities that are at issue whenever there is a mold problem in your home. You should strongly consider consulting a real estate lawyer if your property or health has been damaged because of the mold.
