Montana Residential Landlord and Tenant Act (MRLTA) — MCA §§70-24-101 to 70-24-442

Montana’s comprehensive landlord-tenant framework is codified in two complementary subchapters of the Montana Code Annotated: the Montana Residential Landlord and Tenant Act (MRLTA, MCA §§70-24-101 to 70-24-442), which governs general rights and obligations throughout the tenancy, and the Montana Security Deposit Act (MCA §§70-25-101 to 70-25-206), which separately governs deposit handling, return, and disputes. Montana adopted its RLTA framework in 1977 as a modified version of the Uniform Residential Landlord and Tenant Act (URLTA), though with several notable departures from the standard URLTA text that create a distinctively Montana framework.

Montana landlord-tenant law is administered and enforced through the Montana District Courts, organized into 22 judicial districts across 56 counties. The four major Montana rental markets this guide covers each have their own District Court:

• Billings / Yellowstone County: Thirteenth Judicial District Court, 217 N. 27th St., Billings, MT 59101
• Missoula / Missoula County: Fourth Judicial District Court, 200 W. Broadway, Missoula, MT 59802
• Great Falls / Cascade County: Eighth Judicial District Court, 415 2nd Ave N., Great Falls, MT 59401
• Bozeman / Gallatin County: Eighteenth Judicial District Court, 615 S. 16th Ave., Bozeman, MT 59715

Security Deposits — Five Key Rules (MCA §§70-25-101 to 70-25-206)

1. No Statutory Deposit Cap (MCA §70-25-101)

Montana imposes no statutory maximum on the amount a landlord may collect as a security deposit. A landlord may charge one month’s rent, two months’, three months’, or any other amount as a deposit. MCA §70-25-101 defines “security deposit” broadly without specifying a cap. This places Montana alongside Idaho (also no statutory cap; see Idaho Code §6-321 complete guide) and Wyoming as Mountain West states imposing no deposit ceiling. Landlords should note that while there is no cap, collecting excessive deposits relative to market norms without documented rationale (credit risk, prior damage history, pet ownership) may create practical leasing difficulties in competitive markets like Bozeman and Missoula where tenant pools have alternatives.

2. 30-Day Return Deadline with Itemized Statement (MCA §70-25-201)

After all three trigger conditions are met — (a) the tenancy terminates, (b) the tenant delivers actual possession of the premises, and (c) the tenant provides a written forwarding address — the landlord must, within 30 days, return the deposit balance and provide a written itemized statement specifying each deduction and the dollar amount. The 30-day clock does not begin until all three conditions occur. Best practice: inspect the unit within 72 hours of move-out, photograph all items to be deducted, and mail the deposit and statement via USPS certified mail within 25 days to build in transit time. If no forwarding address is provided at move-out, landlords should send a written request for the address immediately to preserve their timeline.

Montana’s 30-day deadline is the same as Nevada (NRS §118A.242) and Wyoming (Wyo. Stat. §1-21-1207), faster than Oregon (31 days, ORS §90.300(12)), and slower than Idaho (21 days), California (21 days), Alaska (14 days — see Alaska AS 34.03.070 complete guide), Arizona (14 days), and Hawaii (14 days).

3. Actual Damages for Wrongful Withholding — No Multiplier (MCA §70-25-206)

A landlord who wrongfully withholds a security deposit beyond the 30-day deadline, or who makes improper deductions, is liable for the tenant’s actual damages plus court costs and attorney fees. Montana does not impose a statutory damages multiplier for wrongful withholding. This is one of the most landlord-favorable deposit penalty structures in the Mountain West:

4. No Deposit Interest Required

Montana does not require landlords to pay annual interest on security deposits. While landlords must maintain deposits separately from personal funds (best practice, though not always explicitly required), there is no obligation to place deposits in interest-bearing accounts or to account for interest at move-out. This contrasts with Hawaii (5% per annum required, HRS §521-44(d)) and Massachusetts (5% per annum or actual bank rate).

5. Normal Wear and Tear Not Deductible

MCA §70-25-201 limits deductions to damages beyond normal wear and tear. Routine paint scuffing, minor carpet wear from normal use, small nail holes from hanging pictures, and general cleanliness appropriate for age of unit are not deductible. Deductible items include: carpet stains, holes in walls beyond normal picture hanging, broken fixtures, unauthorized pet damage, and unit-specific costs the landlord can document with receipts or estimates.

Eviction Notice Requirements (MCA §70-24-422 and §70-24-441)

Non-payment of rent — 3-day pay-or-quit WITH mandatory cure right (MCA §70-24-422): When a tenant is delinquent in rent, the Montana landlord must serve a written notice demanding payment of the overdue rent within 3 days or surrender of the premises. If the tenant pays in full within 3 days, the tenancy continues and the landlord may not file for eviction on that rent delinquency. Montana’s mandatory cure right within a 3-day period is unusual nationally: most states with 3-day notice periods (Texas, Florida, California, Ohio, Missouri) do not provide a statutory cure right. Montana and Iowa are among the very few states pairing a short 3-day notice period with a mandatory cure right.

Month-to-month termination — 30-day notice (MCA §70-24-441): Either party may terminate a month-to-month tenancy by providing at least 30 days’ written notice prior to the next periodic rental date. This allows landlords to reclaim units for renovation, sale, or other legitimate business purposes without just-cause requirements — Montana has no just-cause eviction statute.

Self-help eviction prohibited: Montana law prohibits landlords from circumventing the court eviction process by changing locks, removing the tenant’s personal property, shutting off utilities, or otherwise interfering with the tenant’s peaceful enjoyment of the premises without a court order. Violations expose landlords to actual damages plus attorney fees.

Billings, Montana — “The Magic City”: Montana’s Largest City and Northern Plains Regional Hub

Billings earned its “Magic City” nickname from its near-overnight growth following the 1882 arrival of the Northern Pacific Railroad — settlers arriving by train found a city that seemed to materialize from the high plains almost instantaneously. Today, Billings (~120,000–125,000 city residents; Yellowstone County ~195,000–205,000 MSA) is the largest city in Montana and the dominant commercial, medical, financial, and distribution hub for a regional trade area extending approximately 500 miles in every direction, encompassing eastern Montana, northern and central Wyoming, western North Dakota, and western South Dakota.

Billings is the ONLY Montana city at the junction of two interstate highways — I-90 (Seattle to Boston) and I-94 (Billings to Detroit) intersect within the city limits, making Billings the most significant interstate junction in the Northern Plains. This geographic position drives BNSF Railway’s critical Billings division point and supports the region’s largest distribution and warehousing infrastructure.

Billings Major Employers

Billings Clinic — Montana’s Largest Independent Health System

Billings Clinic (2800 10th Ave N, Billings, MT 59101) is Montana’s LARGEST INDEPENDENT HEALTH SYSTEM and the single largest employer in Yellowstone County, with approximately 3,500–4,000 employees including physicians, nurses, allied health professionals, administrators, and support staff. Founded in 1911 as Deaconess Hospital and operating under its current name since 2005, Billings Clinic is a not-for-profit organization governed by a community board. Key facts: Level II Trauma Center; Montana’s most comprehensive cancer program with NCI Community Oncology Research Program (NCORP) designation; 8-state regional patient base; specialty services unavailable within 300–500 miles including surgical oncology, cardiac surgery, and neurosurgery; Graduate Medical Education (GME) training ~1,000+ residents and fellows over program history; 2022 net patient revenue ~$1.4B (Billings Clinic annual report). The Clinic drives concentrated rental demand in the West End corridor between Rimrock Road and Billings Clinic campus, where Class A apartment developments targeting healthcare professional households command the highest rents in the Billings market.

ExxonMobil Billings Refinery — Laurel, Montana

The ExxonMobil Billings Refinery, located in Laurel, Montana (approximately 8 miles southwest of downtown Billings on I-90), is one of the LARGEST INLAND REFINERIES IN THE WESTERN UNITED STATES by crude oil throughput. NYSE: XOM (Fortune 4, approximately $398 billion in FY2024 revenue, the world’s largest publicly traded integrated oil and gas company) operates the Laurel facility as a mid-continent refining asset processing crude delivered primarily via the Keystone Pipeline system. The refinery produces gasoline, diesel, jet fuel, asphalt, and other petroleum products distributed across the Northern Plains regional market. Direct employment: approximately 500–700 ExxonMobil employees. Contractor and turnaround workforce: an additional 500–1,000 skilled tradespeople during scheduled maintenance turnarounds (typically spring and fall), which are economically significant multi-month events generating measurable demand for furnished and short-term rental units in Lockwood and Laurel. The energy economy broadly shapes Billings rental demand through oil price cycle effects: the 2022 crude price surge drove elevated Billings absorption, while the 2023–2024 price normalization contributed to modest softening.

1st Interstate BancSystem — Montana’s Largest Bank

1st Interstate BancSystem (NASDAQ: FIBK, 401 N. 31st St., Billings, MT 59101) is Montana’s LARGEST BANK BY TOTAL ASSETS, with $35 billion+ in total assets as of year-end 2024. Founded in Billings in 1968, 1st Interstate has grown organically and through acquisition to operate 300+ branch banking offices across Montana, Wyoming, South Dakota, North Dakota, Idaho, Washington, and Colorado. Approximately 3,200–3,500 total employees system-wide, with the largest concentration — estimated 1,200–1,500 employees — in the Billings metro. As Montana’s largest bank, 1st Interstate serves as a critical financial institution for the agricultural, energy, and small business economy of the Northern Plains, providing farm operating loans, energy project financing, and commercial real estate lending that undergirds the regional economy. Banking sector employment is relatively recession-resistant and provides a stable professional rental cohort in the Downtown/South Side neighborhood near the 1st Interstate headquarters.

BNSF Railway — Billings Division Point

Billings is a critical division point on the BNSF Railway’s northern transcontinental corridor (the former Great Northern and Northern Pacific mainlines, merged into Burlington Northern 1970 and then BNSF 1995). Freight traffic through Billings includes Powder River Basin coal moving east and west, Bakken crude in unit tank trains, Pacific-import intermodal containers, and agricultural grain. BNSF employs approximately 500–700 locomotive engineers, conductors, maintenance-of-way workers, and administrative staff in the Billings metro. Railroad workers have distinctive housing patterns — often owning homes given employment tenure — but trainee conductors and engineers early in their careers constitute a rental cohort in the Heights and Billings Heights neighborhoods.

St. Vincent Healthcare — Level II Trauma Center

St. Vincent Healthcare (1233 N. 30th St., Billings, MT 59101) is Billings’ second major hospital system, employing approximately 2,000–2,500 employees. St. Vincent joined Intermountain Health in 2023, one of the nation’s premier not-for-profit integrated health systems based in Salt Lake City (see Utah landlord-tenant law complete guide). St. Vincent holds Level II Trauma Center designation, making Billings the rare mid-sized city with two Level II Trauma Centers — reflecting its regional hospital hub status. The hospital generates additional healthcare sector demand particularly in the North Billings and Downtown corridors near the 30th Street campus.

NorthWestern Energy (NASDAQ: NWE)

NorthWestern Energy is Montana’s largest regulated electric and natural gas utility, serving approximately 740,000 electric and natural gas customers across Montana, South Dakota, and Nebraska. Headquartered in Butte with significant operations and employee concentrations in Billings, Great Falls, and Missoula, NorthWestern employs approximately 1,400–1,600 Montanans system-wide. As a regulated utility, NorthWestern provides exceptionally stable employment — its workforce is largely insulated from commodity price cycles — contributing a durable professional rental cohort to Billings and Great Falls markets.

Great Falls, Montana — Malmstrom AFB 341st Missile Wing: One of Only Three Minuteman III ICBM Wings in the Entire United States

Great Falls (~59,000–62,000 city residents; Cascade County ~82,000–85,000) is Montana’s third-largest city and the commercial center of north-central Montana. Located at the confluence of the Sun River and the Missouri River (and adjacent to the Great Falls of the Missouri, which Lewis & Clark spent 18 days portaging in June 1805), Great Falls is a market city for the Hi-Line region’s agriculture and a hub for northern Montana healthcare and retail. The defining feature of Great Falls’ economy — and its rental market — is Malmstrom Air Force Base and its extraordinary strategic mission.

Malmstrom AFB 341st Missile Wing — America’s ICBM Nuclear Deterrent

Malmstrom Air Force Base is home to the 341st Missile Wing, one of ONLY THREE Minuteman III intercontinental ballistic missile (ICBM) wings in the entire United States. The 341st MW at Malmstrom, the 90th Missile Wing at F.E. Warren AFB near Cheyenne, Wyoming, and the 91st Missile Wing at Minot AFB in North Dakota together constitute the entire US land-based leg of the nuclear triad — the Minuteman III ICBM force that has been the backbone of American nuclear deterrence since the Cold War. Together, these three wings operate approximately 400 deployed Minuteman III missiles in hardened underground silos.

The 341st Missile Wing at Malmstrom is responsible for approximately 150 deployed Minuteman III missiles distributed across a ~23,000-square-mile operational area spanning north-central Montana — a geographic footprint roughly the size of West Virginia. The missiles sit in hardened, explosion-resistant silos across Cascade, Chouteau, Judith Basin, Fergus, Teton, and other north-central Montana counties. Missile Alert Facilities (MAFs, also called Launch Control Facilities or LCFs) house two-person missile crews who maintain continuous 24-hour alert in underground capsules, ready to launch within minutes of receiving authenticated Emergency Action Messages.

Malmstrom’s workforce includes approximately 3,800 military personnel and civilian employees across the wing’s major organizations:

• 341st Operations Group: Missile combat crews, the 12th and 490th Missile Squadrons, and crew training functions
• 341st Maintenance Group: Missile Maintenance Squadrons performing launch facility maintenance and security forces providing physical security to all 150 launch facilities across the Montana missile field
• 341st Medical Group: Healthcare for Malmstrom personnel and their families
• 341st Mission Support Group: Civil engineering, communications, personnel, contracting, and base support functions
• 120th Airlift Wing (Montana Air National Guard): Co-located at Great Falls International Airport adjacent to Malmstrom; operates C-130H Hercules tactical transport aircraft; approximately 1,000–1,200 Guard personnel

Malmstrom is by far the largest employer in Cascade County. Basic Allowance for Housing (BAH) rates at Malmstrom for 2026: E-5 (Staff Sergeant) with dependents approximately $1,600–$1,850/month; O-4 (Major) with dependents approximately $2,000–$2,250/month. These BAH rates effectively set the price ceiling in a significant portion of the Great Falls rental market, as military families (who constitute an estimated 15–25% of total Great Falls rental demand) will not rent above BAH without out-of-pocket cost. This BAH ceiling compresses rents in the military-adjacent northeast neighborhoods near the Malmstrom Ryan Gate corridor and keeps Great Falls among the most affordable major Montana rental markets. Landlords with military tenants must maintain SCRA (Servicemembers Civil Relief Act) compliance: lease-breaking without penalty is mandatory when an active-duty tenant receives Permanent Change of Station (PCS) orders or deployment orders of 90 or more days.

Benefis Health System — Great Falls’ Healthcare Anchor

Benefis Health System (1101 26th St. S., Great Falls, MT 59405) is the dominant healthcare employer in north-central Montana, with approximately 3,000 employees — the second-largest employer in Cascade County after Malmstrom AFB. Not-for-profit and community-governed, Benefis operates a Level II Trauma Center, comprehensive cancer center, cardiovascular program, psychiatric services, and primary care clinics serving a 10-county regional patient base. The Benefis Health Corridor on the southeast side of Great Falls generates concentrated rental demand for healthcare professionals in neighborhoods adjacent to the hospital campus.

Montana Rent Trajectory 2019–2026: COVID Surge, Partial Softening, and City-by-City Divergence

Montana’s COVID-era rent surge was concentrated in Bozeman and Missoula, which experienced among the highest percentage rent increases of any comparable-size US metros between 2020 and 2022: Bozeman 1BR rents increased approximately 40–67% in 24 months. Billings and Great Falls saw significant but less extreme increases (25–35%), partially buffered by their more industrial employment bases (refining, banking, military) versus the remote-work-driven demand in Bozeman and Missoula. All four cities remain above 2019 baseline levels in 2026.

Despite this rent surge severity, zero rent control proposals were introduced at any Montana city council or county commission during 2020–2026. Missoula City Council (progressive majority, D+15 lean) considered several housing affordability ordinances focusing on upzoning, ADU permitting, and inclusionary housing requirements — but not rent regulation. Bozeman City Commission pursued an aggressive supply-side agenda: a 2020 upzoning allowing mid-rise multifamily in residential zones, a 2021 ADU ordinance eliminating owner-occupancy requirements, and a 2022 update to the Community Plan explicitly supporting higher-density infill. The evidence from this period confirms that Montana’s political and policy response to housing cost pressure is consistently supply-oriented rather than regulatory.

Frequently Asked Questions — Montana Landlord-Tenant Law 2026

Does Montana have rent control in 2026?

No. Montana has no rent control anywhere in the state in 2026. Not Billings, not Missoula, not Great Falls, not Bozeman, not Helena, not Butte, not any other Montana city, town, or county. No Montana municipality has ever enacted rent control. The Montana Legislature has never passed rent-control enabling legislation and has never needed a preemption statute. Montana landlords may raise rents to market rate at lease renewal without restriction.

What is Montana’s security deposit cap?

Montana has no statutory security deposit cap. MCA §70-25-101 does not impose a maximum deposit amount, unlike Alaska (2 months), Hawaii (1 month), Arizona (1.5 months), California (2 months), and Nevada (3 months). Montana landlords may collect any amount as a security deposit. Landlords charging above-market deposits should document the risk rationale (credit profile, prior eviction, pet damage history) in the lease file to protect against discrimination or retaliation claims.

How long does a Montana landlord have to return a security deposit?

30 days. Under MCA §70-25-201, the landlord must return the deposit balance with a written itemized statement of deductions within 30 days after the tenancy terminates, the tenant delivers possession, and the tenant provides a written forwarding address. All three triggers must occur before the 30-day clock starts. Failing to return within 30 days exposes the landlord to actual damages plus attorney fees under MCA §70-25-206 (no statutory multiplier in Montana, unlike Idaho’s 3× treble damages).

Does Montana require landlords to pay interest on security deposits?

No. Montana does not require landlords to pay interest on security deposits held during the tenancy, unlike Hawaii (5% per annum required) and Massachusetts (5% per annum for tenancies over 1 year). Montana landlords owe tenants no interest on deposit funds at move-out regardless of tenancy length or deposit amount.

What is the eviction notice period for non-payment in Montana?

3 days. MCA §70-24-422 requires a written 3-day pay-or-quit notice for non-payment of rent before a landlord can file an eviction action. Montana provides a mandatory cure right — if the tenant pays in full within 3 days of receiving the notice, the tenancy continues. This distinguishes Montana from states like Texas, Florida, and California that also have 3-day notices but provide no statutory cure right. For month-to-month lease terminations, 30 days’ notice is required (MCA §70-24-441).

How does Malmstrom AFB affect the Great Falls rental market?

Malmstrom AFB is Great Falls’ largest employer and most important rental market driver. The 341st Missile Wing (one of only three Minuteman III ICBM wings in the US) employs approximately 3,800 military and civilian personnel, of whom 2,500–4,000 family members rent in the Greater Great Falls area (approximately 15–25% of total Great Falls rental demand). Military BAH rates effectively set a price ceiling in the Malmstrom-adjacent neighborhoods. All active-duty military tenants have SCRA lease-breaking rights when receiving PCS or deployment orders of 90+ days — Great Falls landlords have among the highest per-capita rates of SCRA lease terminations of any Montana city.

Why are Bozeman rents the highest in Montana?

Bozeman’s rents are Montana’s highest due to the convergence of: (1) Montana State University (~17,000–18,000 students creating consistent August move-in demand pressure); (2) Oracle’s Bozeman engineering office (~400–600 high-income tech employees from the 2012 RightNow Technologies acquisition) and tech in-migration; (3) Yellowstone Gateway premium — remote workers from Seattle, San Francisco, and NYC pay Bozeman rents to access Yellowstone NP (90 miles south), Big Sky Resort (45 miles south), and the Gallatin River; (4) constrained supply — Bozeman is surrounded by Gallatin National Forest and agricultural land, limiting greenfield expansion. Bozeman 1BR rents in desirable neighborhoods range $1,200–$2,200 in 2026 — comparable to Spokane, WA or Fort Collins, CO, and 50–100% above Great Falls.

What court handles evictions in Billings, Missoula, Great Falls, and Bozeman?

Montana District Courts handle residential eviction (unlawful detainer) proceedings: Billings/Yellowstone County uses the Thirteenth Judicial District Court (217 N. 27th St., Billings MT 59101); Missoula/Missoula County uses the Fourth Judicial District Court (200 W. Broadway, Missoula MT 59802); Great Falls/Cascade County uses the Eighth Judicial District Court (415 2nd Ave N., Great Falls MT 59401); and Bozeman/Gallatin County uses the Eighteenth Judicial District Court (615 S. 16th Ave., Bozeman MT 59715). Landlords must complete the full notice process (3-day pay-or-quit for non-payment; 30-day for month-to-month termination) before filing. Self-help eviction — changing locks, removing belongings, shutting off utilities — is prohibited under MRLTA regardless of how delinquent the tenant is.
