Which disclosures must a Montana lease include?
Montana landlord-tenant law is governed by the Montana Residential Landlord and Tenant Act (Mont. Code Title 70). The core disclosures a Montana landlord must give at or around lease signing:
| Disclosure | Authority | Applies To |
|---|---|---|
| Owner/manager identity | Mont. Code § 70-24-301 | Every lease |
| Known mold | Mont. Code § 70-16-703 | When the landlord knows of mold |
| Lead-based paint hazard + EPA pamphlet | Title X (federal) | Housing built before 1978 |
The main Montana lease disclosures
Owner/manager identity (Mont. Code § 70-24-301): the landlord must disclose the person authorized to manage the premises and the owner or agent for service and notices
Additional Montana disclosures
Known mold (Mont. Code § 70-16-703): if the landlord knows mold is present, it must be disclosed before or upon entering the lease; a signed disclosure gives liability protection
Federal lead-based paint disclosure
One disclosure applies in every state, Montana included: for housing built before 1978, federal law (Title X; 42 U.S.C. § 4852d) requires the landlord to give a signed lead-warning disclosure, reveal any known lead hazards, hand over any available records, and provide the EPA pamphlet Protect Your Family From Lead in Your Home. Violations can bring civil — and in egregious cases criminal — penalties.
What happens if a Montana landlord skips a required disclosure?
Consequences depend on the disclosure:
- A missed 30-day (or 10-day, no-deductions) deposit return exposes the landlord to the wrongfully withheld amount (§ 70-25-202).
- An undisclosed known mold condition forfeits the liability protection the disclosure provides (§ 70-16-703).
- A federal lead-paint violation carries civil and, in egregious cases, criminal penalties plus tenant damages.
