Montana rules at a glance

Montana rules for a No-Smoking Addendum

Nonpayment	If rent is unpaid when due and the tenant doesn’t pay within 3 days after written notice of nonpayment, the landlord may terminate the rental agreement (§70-24-422(2)).
Landlord entry	24 hours’ notice, at reasonable times (may be posted on the main door)MCA §70-24-312

Landlord entry & access

A Montana tenant may not unreasonably refuse entry to inspect, make repairs or improvements, supply services, or show the unit to buyers, lenders, tenants or contractors. Except in an emergency or where it is impracticable, the landlord must give at least 24 hours’ notice of the intent to enter and may enter only at reasonable times; the notice may be conspicuously posted on the unit’s main entry door (§70-24-312(3)).

The landlord may enter without consent in an emergency, but may not abuse the right of access or use it to harass the tenant. Beyond that, entry requires a court order or an abandoned or surrendered unit. A tenant may not change the locks without permission and must provide keys to any lock they install (§70-24-312).

Ending a Montana tenancy

A periodic tenancy ends on the date named in the notice, not necessarily at the end of a rental period — rent is apportioned day by day unless the parties agree otherwise (§70-24-441(3)).

Notice to end a Montana periodic tenancy (MCA §70-24-441)
Week-to-week	7 days’ written notice
Month-to-month	30 days’ written notice, given at any time

Nonpayment — If rent is unpaid when due and the tenant doesn’t pay within 3 days after written notice of nonpayment, the landlord may terminate the rental agreement (§70-24-422(2)).
Pets & unauthorized occupants — An unauthorized pet or unauthorized person allows a 3-day notice; if the tenant fixes the problem before the date in the notice, the agreement doesn’t terminate (§70-24-422(1)).
Damage or safety threats — Destroying, damaging or removing part of the premises, or creating a reasonable risk of damage to the premises or injury to neighbors, allows termination on 3 days’ written notice (§70-24-422(3)–(4)).
Other breaches — Other noncompliance requires at least 14 days’ notice, and a remediable breach cured in time doesn’t end the tenancy; a repeat of the same breach within 6 months allows a 5-day notice (§70-24-422(1)).
