Montana Residential Landlord-Tenant Laws: A Manage Overview
Official Law Citation: The core of residential tenant rights and landlord duties is found in the Montana Residential Landlord and Tenant Act of 1977 (MCA Title 70, Chapter 24), which has governed the state's rental landscape since its effective date on July 1, 1977.
Residential tenancies in the Treasure State are primarily governed by the Montana Residential Landlord and Tenant Act of 1977 (MRLTA).
Montana law strikes a functional balance between the parties: it is generally considered a moderately landlord-friendly state due to its fast 3-day eviction notices for unpaid rent, but it also imposes strict documentation requirements on landlords to protect tenant security deposits.
Security Deposits and Move-in Conditions
Unlike some states, Montana does not impose a statutory limit on how much a landlord can charge for a security deposit (MCA § 70-25-201). However, the exact rules for returning it depend heavily on the landlord's documentation.
- The Mandatory Condition Report: If a landlord collects a security deposit, they must provide the tenant with a written statement of the property's condition upon move-in (MCA § 70-25-206). If the landlord fails to provide this checklist, they forfeit the right to withhold any portion of the security deposit for damages at move-out (unless they can conclusively prove the tenant caused the specific damage).
- Return Deadlines: If the landlord makes no deductions from the deposit, they must return it within 10 days of lease termination. If they make deductions, they have 30 days to return the remainder along with a written, itemized list of what was withheld (MCA § 70-25-202).
See our Security Deposits guide.
The Montana Eviction Process
Montana allows landlords to act swiftly when tenants violate the lease. Evictions (known legally as an Action for Possession) begin with highly specific notice periods under MCA § 70-24-422:
- 3-Day Notice to Pay or Quit: For unpaid rent.
- 3-Day Notice to Cure or Quit: For specific severe lease violations, including having an unauthorized pet, causing damage to the property, or verbal abuse.
- 14-Day Notice to Cure or Quit: For most other standard lease violations.
- 5-Day Notice to Quit (No Cure): If the tenant repeats the exact same lease violation within a 6-month period, the landlord can serve a 5-day notice requiring them to leave, with no option to fix the issue.
Actions for Possession fall under the concurrent jurisdiction of Justice Court and District Court (MCA § 3-10-302).
See our Eviction Process guide.
Unique Montana Disclosures (Mold)
Montana holds landlords to a unique standard regarding mold. Under MCA § 70-16-703, landlords must include a highly specific Mold Disclosure Statement in the lease agreement acknowledging that mold may be present and that the landlord does not guarantee a mold-free environment. Furthermore, if the landlord knows mold exists or has previously tested for mold, they must disclose those results to the tenant before signing the lease.
See our Required Disclosures guide.
Rent Increases and Late Fees
- Rent Increases: Montana has no statewide rent control laws. However, a landlord must provide at least 30 days' written notice before raising the rent on a month-to-month tenant (or a 7-day notice for a week-to-week tenant). Rent cannot be increased mid-lease for a fixed-term contract unless explicitly allowed in the agreement.
- Late Fees: Montana does not impose a specific statutory cap (such as 10% or $25) on residential late fees. However, any late fee must be explicitly defined in the written rental agreement and must satisfy a "reasonableness" standard to be enforceable in court.
See our Rent Increases and Late Fees guides.
Landlord Maintenance Obligations
Under MCA § 70-24-303, landlords must maintain the premises in a fit and habitable condition. This includes complying with building codes, keeping common areas safe, and maintaining electrical, plumbing, sanitary, heating, and supplied appliances in good working order.
If a landlord fails to supply essential services (like heat in a Montana winter or running water), the tenant can manage the "repair and deduct" remedy (up to one month's rent), terminate the lease, or sue for damages after providing proper written notice.
See our Maintenance Obligations guide.
Forgetting to provide the mandatory Move-In Condition Statement instantly destroys a Montana landlord's ability to claim damages from a security deposit months later. Landager guarantees this never happens. Our leasing flow physically prevents a tenant from counter-signing an initial Montana lease until the standardized Move-in Condition Report and the statutory Mold Disclosure Notice have been digitally signed and appended to the final PDF contract—ensuring your asset is legally insulated from day one.
