Montana Tenant Rights: Key Rules at a Glance

Here are the most important montana tenant rights numbers every renter should know:

Notice to enter 24 hours advance notice required under MCA 70-24-312. The landlord or their agent may enter only at reasonable times and only for legitimate purposes such as inspections, repairs, alterations, improvements, or showings. In an emergency, the landlord may enter without 24 hours notice. Tenants may not unreasonably refuse entry but may object to the specific day or time chosen. Landlords may not abuse their right of access or use it to harass tenants.
Notice to raise rent 30 days written notice required before a rent increase for month-to-month tenancies. For fixed-term leases, rent generally cannot be increased until the lease term expires unless the lease specifically allows mid-term increases. Montana has no cap on how much rent can be raised — only the notice period is regulated.
Notice to end month-to-month 30 days written notice by either the landlord or tenant under MCA 70-24-441. For week-to-week tenancies, 7 days written notice is required.
Notice to end yearly lease For fixed-term leases (including annual leases), the lease expires on its end date and no separate termination notice is required unless the lease states otherwise. Montana statute MCA 70-24-441 does not establish a specific notice period for yearly periodic tenancies — tenants with a fixed-term annual lease should review their lease for any renewal or notice-to-vacate clause.
Max security deposit Montana does not set a statutory maximum on security deposits. The landlord may charge any amount, but it must be stated in the lease agreement.
Deposit return deadline 10 days after move-out if no deductions are claimed and the landlord provided a written move-in checklist documenting the condition of the premises. If the landlord makes deductions for damages beyond normal wear and tear, the landlord has 30 days after move-out to return the remaining balance along with a written itemized statement of deductions under MCA 70-25-201. If the landlord fails to return the deposit or provide an itemized list within the deadline, the tenant may recover the full deposit amount plus damages equal to 100 or 25 percent of the amount wrongfully withheld, whichever is greater.
Statewide rent cap NO. Montana has no statewide rent cap or rent control. In 2023, Governor Gianforte signed HB 463, which preempts all local governments in Montana from enacting any form of rent control. Landlords may raise rent to any amount with 30 days written notice for month-to-month tenancies.

Habitability & Landlord Obligations in Montana

Yes. Under MCA 70-24-303, Montana landlords have a non-waivable duty to maintain the rental in a fit and habitable condition. Specifically, the landlord must: comply with all applicable building and housing codes materially affecting health and safety; make all repairs necessary to keep the premises fit and habitable; keep common areas clean and safe; and maintain all electrical, plumbing, sanitary, heating, ventilating, air-conditioning, and other facilities and appliances in good and safe working order.

This duty cannot be waived by any lease provision.

Other landlord obligations: Beyond habitability and non-retaliation, Montana landlords must: provide a written move-in condition checklist to preserve the right to claim deductions from the security deposit; not lock out tenants or remove their belongings without a court order (self-help evictions are illegal under Montana law); follow proper legal eviction procedures through the courts; provide at least 3 days notice for nonpayment of rent and 14 days notice for other lease violations before pursuing eviction; install and maintain functional smoke detectors and carbon monoxide detectors; and disclose known lead-based paint hazards in units built before 1978.

Retaliation & Discrimination Protections

Retaliation: Yes. Under MCA 70-24-431, a Montana landlord may not retaliate by raising rent, decreasing services, or bringing or threatening an eviction action after the tenant has: (1) complained to a government agency about a health or safety code violation affecting the premises; (2) complained in writing to the landlord about a failure to maintain the premises under MCA 70-24-303; or (3) organized or joined a tenants’ union or similar organization.

If the landlord takes any of these retaliatory actions within 6 months of the tenant’s protected activity, the court presumes the landlord acted in retaliation. The tenant may use retaliation as a defense in any eviction proceeding and may also pursue remedies under MCA 70-24-411.

Additional protected classes in Montana: Montana’s Human Rights Act (Title 49, Chapter 2, MCA) prohibits housing discrimination based on race, color, national origin, religion, creed, sex, age, marital status, familial status (presence of children under 18), and physical or mental disability. The state-specific classes beyond the federal Fair Housing Act are marital status, age, and creed.

Complaints must be filed with the Montana Human Rights Bureau within 180 days of the alleged violation. It is also illegal to retaliate against anyone who files a housing discrimination complaint.

What You Can Do When Your Landlord Violates the Law

If a Montana landlord fails to maintain the premises in a habitable condition, tenants may pursue several remedies under MCA 70-24-406 after giving the landlord written notice: (1) Repair and deduct — if the landlord fails to make repairs within 14 days (or sooner for emergencies), the tenant may hire someone to make the repair and deduct the cost from rent, up to the lesser of 300 or one-half of one month’s rent; (2) Terminate the lease — if the landlord fails to remedy a material health or safety violation within the required timeframe, the tenant may give written notice terminating the rental agreement; (3) Sue for damages — tenants may file a lawsuit seeking damages, rent abatement, or injunctive relief for breach of the habitability warranty; (4) Defense against eviction — tenants may raise the landlord’s failure to maintain habitability as a defense in an eviction proceeding.

Note: Montana does not generally allow tenants to withhold rent entirely without a court order.

Other Montana tenant protections: Montana has several unique provisions: (1) Move-in condition checklist — if the landlord does not provide a written checklist of the premises’ condition at move-in, the landlord forfeits the right to withhold any portion of the security deposit for damages; (2) The 10-day accelerated deposit return only applies when no deductions are made AND the landlord provided the move-in checklist — otherwise the 30-day timeline applies; (3) Self-help evictions are prohibited — a landlord who changes locks, removes doors or windows, or shuts off utilities to force a tenant out may be liable for damages; (4) Tenants served with eviction papers have only 5 business days to file an Answer with the court or risk a default judgment; (5) Montana’s 2023 HB 463 statewide rent control preemption means no Montana city or county can pass rent control ordinances; (6) Montana’s implied warranty of habitability is non-waivable — any lease clause purporting to waive the landlord’s duty to maintain the premises is void and unenforceable.
