Landlord notice deadlines — Montana
In Montana, the checked deadlines on this page cover: pay or quit, ending a tenancy, raising the rent. Each figure carries its statute and the stamp Rules checked October 2026. Run your exact dates through the checker — the period is only half the answer; the counting rule is the other half.
| Pay or quit | 3 calendar days — the tenant may pay and cure (Mont. Code § 70-24-422(2)). 3 days to pay or vacate after written notice of nonpayment and the landlord's intent to terminate. Paying in full within the 3 days stops the termination. |
|---|---|
| End a tenancy | 30 days — month-to-month (Mont. Code § 70-24-441). 30 days' written notice, no reason required; the termination must not be retaliatory or discriminatory. 7 days — week-to-week (Mont. Code § 70-24-441). 7 days' written notice. |
| Raise the rent | 30 days (Mont. Code § 70-24-441). No cap on the amount; 30 days' written notice for a change in a month-to-month tenancy. |
| How days are counted | If hand-delivered, the period starts the day after delivery. Mailed notice is deemed served 3 days after mailing (Mont. Code § 70-24-108). |
| Allowed service methods | hand delivery mail (certificate of mailing or certified mail; deemed served 3 days after mailing) email if the tenant provided one in the lease (Mont. Code § 70-24-108) |
| Just cause | No statewide just-cause requirement. |

Local rules sit on top of state law in many places — city just-cause lists, rent boards, and prescribed local forms. A state deadline is the floor of the analysis, never a promise that no local rule adds to it.
The paper that goes with the date
The checker gives you the date. The kit gives you the notices: pay or quit, non-renewal / termination, and rent increase letters generated from these same checked deadlines, a letter builder that fills in your dates and names, the move-in and move-out inspection checklists, and the proof-of-service checklist.
One-time payment. No subscription. The checker stays free either way.
