How much notice is required to raise the rent in Montana?

Montana has no statute requiring advance notice of a rent increase — the 30-day figure everyone quotes is derived from Mont. Code Ann. 70-24-441(2), which lets either party end a month-to-month tenancy with at least 30 days' written notice before the date designated in the notice (7 days for week-to-week), so a landlord proposing higher rent is effectively offering new terms the tenant can decline by leaving on 30 days' notice.

There is no limit on the size or frequency of increases: Montana has no rent control, a 2023 statute (7-1-111(26), effective October 1, 2023) expressly strips every self-governing city and county of the power to control rents on private residential or commercial property, and a companion 2023 act makes the state landlord-tenant statutes an exclusive statewide regulatory standard that local governments may not deviate from or add to. For fixed-term leases rent is locked by contract, and a statutory default caps either side's damages for a no-cause early termination at one month's rent.

Montana rent increase notice at a glance

Notice — month-to-month	No rent-increase statute — notice derives from tenancy-termination rules (see summary)
Varies by increase size	Not addressed by statute
Fixed-term leases	Rent is fixed for the lease term as a matter of contract, and no section of the act addresses mid-term or renewal increases. Related default: if either party terminates a fixed-term agreement early without cause, damages are capped at 1 month's rent or a lease-agreed amount not exceeding 1 month's rent (70-24-201(2)(f), added effective 2021-05-14).
Statewide rent control / stabilization	No
Rent control details	No rent control exists anywhere in Montana, and state law preempts it twice over. Mont. Code Ann. 7-1-111(26) (added by SB 105, Ch. 319, L. 2023, effective 2023-10-01) denies self-governing local government units 'any power to control the amount of rent charged for private residential or commercial property,' excepting property the local unit owns or holds through a housing authority. Independently, 7-1-111(13) (as rewritten by HB 283, Ch. 572, L. 2023, effective on approval 2023-05-18) denies any local power to license or regulate landlords beyond Title 70 chapters 24, 25, and 33, or to 'deviate from or add to the exclusive application' of those chapters, and 70-24-102(2)(c) declares the act's purpose to 'create an exclusive regulatory standard throughout the state and its political subdivisions.' General-power (Dillon's rule) local governments never had rent-control authority to begin with.

Notes and caveats

The 30-day figure is a derivation, not a rent-increase statute — No statutory rent-increase figure is shown here, under the same derivation convention used for Texas, Nebraska and Mississippi: 70-24-441 addresses only termination of a periodic tenancy and never mentions rent increases. The working rule is the 30-day written notice to end a month-to-month tenancy (7 days week-to-week), explained as the derivation it is rather than shown as a statutory rent-increase figure.
The 30 days run to the date named in the notice — Unlike Nebraska, Montana has no periodic-rental-date anchor — the notice period runs to 'the date designated in the notice' — and 70-24-441(3) makes rent apportionable day to day.
Nothing was added between 2021 and 2025 — No rent-increase notice rule was enacted in the 2021, 2023 or 2025 sessions; 70-24-441 was last amended in 2007 (Ch. 267).
High-traffic debunk: the rent-control ban is SB 105, not HB 463 — Many secondary sources (Hemlane, NAA among them) attribute Montana's rent-control ban to 'HB 463 (2023), signed March 2, 2023.' The official enrolled HB 463 of 2023 is a food-procurement bill amending 18-4-132. The preemption act is SB 105 (Fitzpatrick), Ch. 319, L. 2023, signed May 1, 2023; with no effective-date clause it took effect October 1, 2023 under the 1-2-201(1)(a) default — the first day of October following passage and approval.
For history-line readers: the 2025 amendment to 7-1-111 is unrelated — Ch. 537, L. 2025 (HB 809) amended 7-1-111 but only added subsection (31), on gun laws. It carries no landlord content.
The preemption reaches every locality in practice — By its terms 7-1-111 binds self-government-powers units. General-power local governments never had rent-control authority to begin with under Dillon's rule, so the bar is comprehensive in practice — and no Montana municipality has ever had rent control.
Mobile-home lots run on a separate scheme — Out of scope here but adjacent: Title 70 ch. 33 governs lot rentals, those tenancies are month to month by default, and they have their own termination grid at 70-33-433.

How this record was verified: Direct read of statute text on the official Montana Code Annotated site (mca.legmt.gov, MCA 2025 edition): all nine sections of Title 70 ch. 25 and sections 70-24-103, -108, -201, -202, -312, -403, -404, -410, -422, -441 plus 7-1-111 and 1-2-201, each section behind a figure here read twice independently with all figures matching verbatim (30-day/10-day deposit return, 24-hour cleaning cure window, certified-mail 3-day service rule, 24 hours' entry notice, 30-day/7-day periodic termination notice, rent-control preemption text). Every amendment claim additionally pinned character-for-character from official enrolled bills downloaded via the Legislature's document API (docs.legmt.gov): HB 444 (2025, Ch. 656) and HB 488 (2023, Ch. 383) for 70-25-201/-202, HB 810 (2025, Ch. 768) for 70-24-103/-201, HB 541 (2021, Ch. 536) for 70-24-312/70-24-201/70-25-201, SB 105 (2023, Ch. 319) and HB 283 (2023, Ch. 572) for 7-1-111; chapter numbers pinned from the official bill-to-chapter tables (archive.legmt.gov MCA Supplements).

Negative checks (no deposit cap, no interest or separate-account rule, no rent-increase notice statute, no late-fee cap or grace period) run twice against the complete section indexes of ch. 24 parts 1-4 and ch. 25 parts 1-2. 2025 session sweep: HB 444 and HB 810 enacted and effective (incorporated); HB 304, HB 277, HB 305, HB 306 died in committee; 69th Legislature adjourned, next regular session January 2027; no on-topic special-session activity.
