Montana Landlord Required Disclosures

Montana imposes a set of highly specific statutory disclosures that landlords must provide to prospective tenants before a lease is signed. Failing to provide these disclosures not only exposes the landlord to civil liability but can also invalidate portions of the lease agreement.

1. The Mandatory Mold Disclosure

Montana has one of the strictest mold disclosure laws in the United States. Under MCA § 70-16-703, a landlord must provide a highly specific written statement regarding mold in every residential lease.

The General Statement

Every rental agreement must contain a disclosure statement advising the tenant that the property may contain mold, that the landlord cannot completely eliminate the possibility of mold, and that it is the tenant's responsibility to investigate the property for mold if they suffer from health issues.

Prior Testing and Known Mold

If the landlord actually knows that mold is present in the unit, or if the unit has been previously tested for mold, they must disclose this specific information to the tenant. If the property was tested, the landlord must:

• Inform the tenant of the testing.
• Provide a copy of the test results (if available).
• Provide evidence of any subsequent treatment or remediation.

If the landlord complies entirely with this disclosure law and the tenant signs a written acknowledgment, the landlord is generally granted immunity from civil liability in Montana courts for any mold-related damages or injuries the tenant might suffer.

2. Methamphetamine Contamination Disclosure

Under Montana's Methamphetamine Cleanup Act (MCA Title 75, Chapter 10, Part 13), if a property has been used as a clandestine methamphetamine drug lab and the landlord has been officially notified of this by law enforcement or the environmental quality department, they must disclose this to all prospective tenants.

If the property has been effectively decontaminated according to state standards and legally removed from the state's contaminated properties registry, the disclosure requirement is usually lifted.

3. Landlord and Agent Identity

Per MCA § 70-24-301, the landlord must disclose in writing the name and address of:

• The person authorized to manage the premises.
• An owner of the premises, or a person authorized to act for and on behalf of the owner for the purpose of receiving notices, demands, and legal process.

4. Move-In Condition Statement

If a landlord collects any security deposit from the tenant, they must provide a written "Statement of Condition of the Premises" prior to the tenant taking possession. Without this prior disclosure of the baseline condition, the landlord cannot legally withhold security deposit funds for damages upon move-out. (See our Security Deposits guide for more details).

5. Federal Lead-Based Paint Disclosure

While a federal rather than a state law, it is rigidly enforced in Montana. If the residential property was constructed prior to 1978, the landlord must:

1. Provide the tenant with the EPA-approved information pamphlet on identifying and controlling lead-based paint hazards ("Protect Your Family From Lead In Your Home").
2. Disclose any known information concerning lead-based paint or lead-based paint hazards in the building.
3. Include a specific Lead Warning Statement in the lease, along with an acknowledgment signed by the tenant.
