Short answer: In a New Hampshire month to month lease, the landlord of most rental housing (“restricted property”) can end your tenancy only for a reason listed in RSA 540:2, II, with 30 days’ written notice under RSA 540:3, II. You can leave on 30 days’ written notice under RSA 540:11, II, but if the notice expires mid-month you owe rent up to the next due date unless your lease says otherwise.
| Rule | New Hampshire | Statute |
|---|---|---|
| Tenant notice to end month-to-month | 30 days, in writing | RSA 540:11, I-II |
| Rent if tenant’s notice ends mid-month | Owed up to the next rent due date, unless lease says otherwise | RSA 540:11, II |
| Landlord notice (no-fault reasons) | 30 days, in writing, stating the reason | RSA 540:3, II-III |
| Reason required? | Yes for restricted property; no for nonrestricted | RSA 540:2, I-II |
| What counts as nonrestricted | Single-family house (owner has 3 or fewer); owner-occupied building of 4 units or fewer | RSA 540:1-a |
| Rent increase notice (restricted) | 30 days’ written notice of amount and effective date | RSA 540:2, IV |
| Retaliation presumption | Rent increase within 6 months after a covered complaint | RSA 540:13-b |
Restricted vs. Nonrestricted: The Question That Decides Everything
New Hampshire splits residential rentals into two groups in RSA 540:1-a. “Nonrestricted property” includes a single-family house whose owner owns no more than three single-family houses, a unit in an owner-occupied building with four or fewer units, and a single-family house a bank took through foreclosure. Everything else rented for residential purposes is “restricted property,” which covers most apartment buildings and many larger landlords’ houses.
The distinction matters because RSA 540:2, I lets the owner of nonrestricted property end any tenancy with a written notice to quit, with no reason, while paragraph II limits the owner of restricted property to listed grounds. Those include unpaid rent, substantial damage, breaking a material lease term, behavior affecting others’ health or safety, certain lead-hazard abatement, failure to prepare for pest treatment, and “other good cause.”
“Other good cause” is broader than it sounds
RSA 540:2, V says other good cause includes “any legitimate business or economic reason” and need not be based on anything you did. A plan to renovate, sell or move a relative in may qualify. When the cause is based on your own conduct, paragraph III requires the landlord first to give you a written warning that the conduct would be grounds for eviction in the future, served under RSA 540:5 or by certified mail.
So a New Hampshire month-to-month tenancy in restricted property is not ended “for no reason.” But it is not strict just-cause protection either, because an honest business reason can be enough.
The New Hampshire Month to Month Lease Notice Periods
For landlords, RSA 540:3, II says 30 days’ notice is sufficient in all residential cases, with 7 days allowed for nonpayment, substantial damage, health-and-safety behavior, or a domestic-violence perpetrator remaining after an RSA 540:11-b termination. Paragraph III requires the eviction notice to state the reason “with specificity.” Under RSA 540:5, I, any person may serve it, either on you personally or by leaving it at your last and usual place of abode.
Because RSA 540:3, II applies to “all residential tenancies,” the statute sets no shorter period for week-to-week renters. A weekly residential tenancy gets the same 30-day notice for a no-fault reason.
For tenants, RSA 540:11, I says you may end your tenancy by written notice “in the same manner as the lessor,” and paragraph II sets 30 days for a tenancy at will from month to month. The catch: if the termination date in your notice does not match your rent due date, you are responsible for rent “for the entire month in which the notice expires, up to the next rent due date,” unless the lease provides otherwise.
How These Tenancies Begin
New Hampshire statutes speak of a “tenancy at will, from month to month” in RSA 540:11, II, which is how the law describes a residential arrangement with no fixed end date. Most begin one of three ways: an oral agreement to pay monthly rent, a written agreement that sets rent without an end date, or a fixed-term lease that runs out while the tenant keeps paying and the landlord keeps accepting rent. Chapter 540 does not set a separate double-rent or other penalty for a tenant who holds over; a landlord’s remedy is the possessory action under the same chapter.
One rule bridges fixed leases and month-to-month tenancies. RSA 540:2, II(i) makes the expiration of a lease a ground for eviction only if the original term was 12 months or longer (or renewals add up to 12 months), the landlord gave written notice of non-renewal at least 60 days before the term ended, and the landlord files a possessory action within 6 months of expiration. If those conditions are not met, the end of your lease alone is not a ground to evict you from restricted property.
Rent Increases on a Month-to-Month
New Hampshire has no statewide cap on rent. The notice rule appears inside the good-cause section: under RSA 540:2, IV, your refusal to agree to a rent increase counts as good cause for eviction only if the landlord gave you written notice of the amount and the effective date at least 30 days before the increase takes effect. A verbal “rent’s going up next month” does not meet that standard.

Timing can reveal retaliation. RSA 540:13-b creates a rebuttable presumption that a possessory action, rent increase or substantial change in the tenancy is retaliatory if it comes within 6 months after the landlord received notice of a covered code or fitness complaint. RSA 540:13-a makes retaliation a defense to a possessory action, except when you owe a week’s rent or more.
Worked Example: A Concord Apartment
Priya rents a unit in a 12-unit Concord building, which makes it restricted property, for $1,400 a month due on the 1st. She has no written lease. On February 10 she hands her landlord written notice that she will leave on March 12, exactly 30 days later. Under RSA 540:11, II, because March 12 is not her rent due date, she owes rent through the next due date, April 1, so all of March’s $1,400 is owed.
Had she delivered the notice on or before January 30 and named March 1 as her move-out date, her tenancy would end on a rent due date and she would owe nothing for March. Our notice deadline calculator lines up the dates for you.
Now reverse it. If her landlord wanted the unit back to renovate, RSA 540:2, II(e) and V could treat that as other good cause, but the landlord would need a written 30-day eviction notice stating that reason under RSA 540:3, II and III.
Frequently Asked Questions
Can a New Hampshire landlord end my month-to-month tenancy without a reason?
Only if you rent nonrestricted property, such as a unit in an owner-occupied building of four or fewer units, under RSA 540:2, I and 540:1-a. Otherwise the landlord needs a ground listed in RSA 540:2, II, though “other good cause” includes legitimate business or economic reasons.
Why do I owe a full month if I gave exactly 30 days’ notice?
RSA 540:11, II makes you responsible for rent up to the next rent due date when your termination date does not match it, unless your lease provides otherwise. Timing your notice so it expires on a due date avoids the extra rent.
Can I be evicted for refusing a rent increase in New Hampshire?
Yes, from restricted property, but only if the landlord gave written notice of the new amount and effective date at least 30 days in advance under RSA 540:2, IV. An increase within 6 months after a covered complaint is presumed retaliatory under RSA 540:13-b.
Do weekly renters in New Hampshire get less notice?
Not for a no-fault termination. RSA 540:3, II sets 30 days as sufficient for “all residential tenancies,” with 7 days only for listed fault grounds such as nonpayment.
Does my landlord have to say why in the notice?
Yes. RSA 540:3, III requires the eviction notice to state the reason with specificity, and a conduct-based “other good cause” also requires an earlier written warning under RSA 540:2, III.
