Montana: Eviction Notice Requirements

Requirements one by one

Governing law

Montana's eviction-notice rules are in the Montana Residential Landlord and
Tenant Act, Mont. Code Ann. Title 70, chapter 24 — a version of the Uniform
Residential Landlord and Tenant Act. The core notice section is § 70-24-422,
which covers both nonpayment and other lease noncompliance; § 70-24-441 sets the
no-cause periodic-tenancy notice; § 70-24-108 says how a notice must be
delivered; and § 70-24-431 bars retaliatory eviction.

Notice for unpaid rent

If rent is unpaid when due, the landlord must give "written notice... of
nonpayment and the landlord's intention to terminate," and the tenant then has
"3 days" to pay (§ 70-24-422(2)). Pay the rent within those 3 days and the
tenancy does not terminate; miss the deadline and the landlord may terminate and
require you to move out.

Notice for a lease violation

For a lease violation other than rent, Montana's default is a 14-day cure
period: for a noncompliance "not listed in subsection (1)(b), (1)(c), or (1)(f),
the notice period is 14 days" (§ 70-24-422(1)(d)), and "if the noncompliance is
remediable... and the tenant remedies the noncompliance before the date
specified in the notice, the rental agreement does not terminate"
(§ 70-24-422(1)(a)). Three categories are singled out for a shorter 3-day
notice: an unauthorized pet ((1)(b)), unauthorized people living in the unit
((1)(c)), and "verbal abuse of the landlord," which is curable ((1)(f)). And if
"substantially the same act or omission" that was already noticed "recurs within
6 months," the landlord can terminate on "at least 5 days' written notice"
((1)(e)).

Unconditional quit (no cure allowed)

Two grounds let a Montana landlord terminate on 3 days' notice with no chance to
cure. If the tenant "destroys, defaces, damages, impairs, or removes any part of
the premises," the landlord may terminate "upon giving 3 days' written notice"
(§ 70-24-422(3)); and if the tenant "creates a reasonable potential that the
premises may be damaged or destroyed or that neighboring tenants may be injured,"
the same 3-day notice applies (§ 70-24-422(4)). A repeat of the same
already-noticed violation within 6 months is also effectively unconditional — 5
days' notice and out (§ 70-24-422(1)(e)).

Ending a month-to-month tenancy

To end a month-to-month tenancy for no fault, the landlord (or the tenant) gives
"at least 30 days' notice in writing" (§ 70-24-441(2)); a week-to-week tenancy
takes "at least 7 days" (§ 70-24-441(1)). The statute expressly lets a landlord
skip the for-cause route and use this 30-day no-cause notice instead — "the
landlord is not bound by [§ 70-24-422] in the event that the landlord elects to
use the 30-day notice" (§ 70-24-422(7)).

How the notice must be served

Under § 70-24-108, a notice can be delivered in hand, or "mailed with a
certificate of mailing or by certified mail" to the tenant's designated or
last-known address — in which case "service of the notice is considered to have
been made on the date 3 days after the date of mailing." Montana also allows
electronic notice to an email address the tenant provided in the rental
agreement, complete on a read receipt or a (non-automatic) reply. A for-cause
notice must "specify the acts and omissions constituting the noncompliance" and
the date the tenant must vacate (§ 70-24-422(1)).

Tenant's right to cure/reinstate

For a curable violation, fixing it "before the date specified in the notice"
keeps the tenancy alive (§ 70-24-422(1)(a)); for nonpayment, paying within the
3-day window does the same (§ 70-24-422(2)). Montana also protects tenants who
complain. A landlord "may not retaliate... by bringing or threatening to bring
an action for possession" after the tenant complains to a code agency, complains
in writing to the landlord, or joins a tenants' union (§ 70-24-431(1)), and "a
complaint within 6 months before the alleged act of retaliation creates a
rebuttable presumption" of retaliation (§ 70-24-431(3)) — though that protection
does not apply if "the tenant is in default in rent." Self-help is expensive for
landlords: an unlawful lockout or utility shutoff lets the tenant recover
possession plus "not more than 3 months' periodic rent or treble damages,
whichever is greater" (§ 70-24-411).

What trips people up

Not every quick notice is 3 days for the same reason. Montana uses the
3-day period for several different situations — nonpayment, an unauthorized pet,
unauthorized occupants, verbal abuse of the landlord, and property damage or
danger — but only some of them let you cure. Nonpayment, the pet, occupants, and
verbal-abuse grounds can be fixed; damaging the premises or endangering
neighbors (§ 70-24-422(3), (4)) cannot.

A landlord can skip "cause" entirely with a 30-day notice. Because Montana
has no statewide just-cause requirement, a landlord who does not want to prove a
violation can simply serve a 30-day no-cause notice to end a month-to-month
tenancy (§ 70-24-422(7); § 70-24-441(2)). The trade-off is time: the for-cause
notices are shorter.

Complaining first can flip the burden. If you complained about a
health-and-safety problem or joined a tenants' organization within the last 6
months, § 70-24-431 presumes a later eviction is retaliatory and gives you a
defense — unless you are behind on rent, which removes the presumption.

Common questions

I got a 3-day notice for unpaid rent — can I still pay and stay? Yes. If you
pay the rent within the 3 days stated in the notice, the tenancy does not
terminate (§ 70-24-422(2)). After that window closes the landlord may terminate
and file for possession.

My landlord says I have an unauthorized pet — how long do I have? Three
days (§ 70-24-422(1)(b)). Because that noncompliance is remediable, removing the
pet before the date in the notice keeps the tenancy alive (§ 70-24-422(1)(a)).

Can my landlord end my month-to-month lease without giving a reason? Yes, on
at least 30 days' written notice (§ 70-24-441(2)). Montana has no statewide
just-cause law, so a landlord does not have to state a reason — but the
termination cannot be retaliation for a recent complaint.

Can my landlord change the locks or shut off the utilities to force me out?
No. An unlawful lockout or a shutoff of heat, water, or power lets you recover
possession and "not more than 3 months' periodic rent or treble damages,
whichever is greater" (§ 70-24-411). Only a court can order an eviction.
