North Dakota Rent Increase 2026: 30-Day Month-to-Month Notice & 90-Day Mobile-Home Park Rule
North Dakota uses a 30-day written-notice rule for month-to-month lease changes, while month-to-month mobile-home park tenancies use a separate 90-day rule. Fixed-term leases and park ownership changes require separate review.
The short answer
North Dakota's current ordinary rent-change rule is tenancy-specific. North Dakota Century Code § 47-16-07 applies to month-to-month leases and allows a landlord to change lease terms, including rent, effective at the end of the month after giving written notice at least 30 days before that month expires. The North Dakota Attorney General summarizes the same rule and says a month-to-month landlord may raise rent by any amount with at least 30 days' written notice.
That does not make 30 days a universal answer for every North Dakota rental. The Attorney General separately states that rent generally cannot be raised until after the lease period ends. A fixed-term lease, subsidized or program housing, and a mobile-home park can therefore require a different analysis. Max Rental Tools keeps the automatic North Dakota notice-day handoff review-gated until the tenancy and property type are confirmed.
How the 30-day month-to-month rule works
Section 47-16-07 is written specifically for leases from month to month. A landlord may change the lease terms to take effect when the month expires by giving written notice at least 30 days before expiration. If the tenant remains after that month, the terms, rent and conditions stated in the notice become part of the lease under the statute.
The statute also says notice may be served in a reasonable manner that actually informs the tenant of the changes. A landlord should still preserve a dated copy of the notice and reliable delivery evidence, and should check the signed agreement and any housing-program requirements before assuming the state baseline is the only rule that matters.
Fixed-term leases are different
The North Dakota Attorney General states that rent generally cannot be raised until after the lease period ends. That distinction is important for a six-month, one-year or other fixed-term lease: the month-to-month change-of-terms statute should not be treated as authority to rewrite the rent in the middle of a fixed term.
Review the signed lease for the term end date, any lawful rent-adjustment language, automatic-renewal provisions and the proposed effective date. If the proposal is for the next lease term rather than the current term, a Lease Renewal Notice may be more appropriate than treating the situation as a month-to-month rent change.
North Dakota does not use a general statewide percentage cap for the ordinary month-to-month rule
The Attorney General's current tenant-rights guidance states that a month-to-month landlord may raise the rent by any amount with the required advance written notice. North Dakota therefore does not use one general statewide percentage ceiling in that ordinary month-to-month framework.
A percentage calculation is still useful for understanding the size of the proposed change, but it is not the only legal check. Lease terms, subsidized or federally regulated housing, fair-housing requirements, special property statutes and other applicable rules can affect whether and when an increase is permissible.
Cities and counties generally cannot impose private-property rent control
North Dakota Century Code § 47-16-02.1 prohibits a political subdivision from enacting, maintaining or enforcing an ordinance or resolution that controls the amount of rent charged for private residential or commercial property.
The same section preserves a political subdivision's ability to manage and control residential property in which it has a fee-title interest. That means the preemption rule should not be rewritten as a claim that every government-connected or program rental is governed only by the private-market baseline.
A tenant has a 25-day exit option after a month-to-month change
North Dakota's termination statute adds an important companion rule. Under § 47-16-15, if a landlord changes month-to-month lease terms under § 47-16-07, the tenant may terminate the lease at the end of the month by giving at least 25 days' notice.
That tenant option is different from the landlord's 30-day change-of-terms notice. Keeping the two clocks separate helps avoid a common mistake: treating the landlord's notice period and the tenant's response or termination path as the same deadline.
Mobile-home parks use a separate 90-day month-to-month rule
Do not apply the ordinary 30-day apartment rule automatically to a mobile-home park. North Dakota Century Code § 47-10-28 says any month-to-month tenancy agreement in an existing mobile-home park must provide a minimum of 90 days' notice before a rent increase becomes effective.
The same provision adds a purchaser-specific protection: a person who buys an existing mobile-home park may not increase a tenant's monthly rental obligation for six months if the rental amount was increased within the 60-day period before the new owner acquired the park. Park residents and operators should use this park-specific framework rather than a generic month-to-month rent notice.
Example: ordinary month-to-month rental versus a park lot
Example 1: an ordinary apartment is rented month to month. The landlord proposes a higher rent for the next monthly period. Section 47-16-07 requires written notice at least 30 days before the end of the month, while the lease and any program requirements still need review.
Example 2: a resident owns a mobile home and rents a space month to month in an existing park. The park-specific statute uses a 90-day minimum instead. If the park was recently purchased and rent had already increased shortly before the sale, the purchaser's separate six-month restriction also needs to be checked. These situations should not be collapsed into one automated deadline.
Use Max Rental Tools after confirming the North Dakota tenancy
Start with the North Dakota state guide and rent-increase calculator to measure the proposed change and organize the facts. Confirm whether the tenancy is month to month, fixed term, assisted or program housing, or a mobile-home park tenancy before relying on a notice period.
Then use the Rent Increase Notice when the ordinary month-to-month change path is actually confirmed, the Lease Renewal Notice when the proposal concerns a later fixed term, the Month-to-Month Rental Agreement when the periodic arrangement itself needs to be documented, or the Rent Ledger when payment history matters. Max Rental Tools intentionally keeps North Dakota's automated notice timing review-gated so the 30-day and 90-day rules are not mixed together.
