New Hampshire Rent Increase Rules at a Glance

Statewide rent cap	NO — New Hampshire has no statewide rent cap or percentage limit. Landlords may raise rent by any amount with proper notice. The only constraints are procedural (written notice) and protective (anti-retaliation under RSA 540:13-a and RSA 540:13-b).
Notice required before increase	30 days written notice for standard residential month-to-month tenancies (RSA 540:2, IV). 60 days written notice for manufactured housing (mobile home) park tenants (RSA 205-A:6). Notice must be served per RSA 540:5 or by certified mail, stating the amount and effective date of the increase.
How often rent can be raised	No statutory limit on frequency. For month-to-month tenancies, a landlord may raise rent as often as proper 30-day written notice is given each time. For fixed-term leases, rent is locked for the lease term unless the lease itself contains a clause permitting mid-term increases.
During a fixed-term lease	NO — A landlord cannot raise rent during a fixed-term lease in New Hampshire unless the lease itself contains a clause explicitly permitting mid-term rent increases. Once the fixed-term lease expires and converts to a month-to-month tenancy, the landlord must provide 30 days written notice before any increase takes effect.

Retaliatory increases: YES — New Hampshire prohibits retaliatory rent increases. Under RSA 540:13-b, a rebuttable presumption of retaliation is created when a rent increase is initiated within 6 months after: the landlord received notice of an alleged housing violation (from the tenant or a government body), the landlord completed repairs to remedy such a violation, the landlord received notice the tenant filed an action under RSA 540-A, or the landlord discovered the tenant engaged in protected activity under RSA 540:13-a (such as reporting code violations or organizing with other tenants).

The burden shifts to the landlord to prove the increase was not retaliatory. However, this presumption does not apply if a court finds the tenant’s complaint was primarily intended to prevent eviction.

New Hampshire Cities With Local Rent Control

NONE — No city or county in New Hampshire currently has a local rent control or rent stabilization ordinance in effect.

Exempt properties: New Hampshire has no rent cap, so there are no exemptions from one. However, NH law distinguishes between “restricted” and “nonrestricted” property (RSA 540:1-a). Nonrestricted property includes: single-family houses where the owner owns no more than 3 at one time, rental units in an owner-occupied building with 4 or fewer dwelling units, and single-family houses acquired by banks through foreclosure.

Nonrestricted landlords can terminate a tenancy for any reason with proper notice. Restricted property landlords (larger multi-unit buildings, non-owner-occupied) can only terminate for enumerated causes, one of which is a tenant’s refusal to accept a properly noticed rent increase.

State preemption: New Hampshire does not have an explicit state statute preempting local rent control. However, no municipality in New Hampshire has enacted a rent control ordinance, and a bill that would have explicitly authorized municipalities to enact rent control was voted down by the NH House of Representatives. In practice, New Hampshire operates without any rent control at either the state or local level.

What to Do If Your Rent Increase Is Illegal

If you believe a rent increase is retaliatory (within 6 months of reporting a housing violation or exercising a protected right), you may raise retaliation as a defense in court under RSA 540:13-a and RSA 540:13-b. You may also file a complaint about prohibited landlord practices under RSA 540-A. Many tenants contact 603 Legal Aid (603legalaid.org) for free legal help.

You can also visit the NH Circuit Court District Division for landlord-tenant dispute procedures. If your landlord did not provide proper 30-day written notice (or 60 days for manufactured housing), the rent increase may not be enforceable — check with your local court. Keep copies of all notices, letters, and communications as evidence.

Other New Hampshire rent rules: 1) RESTRICTED vs. NONRESTRICTED PROPERTY: New Hampshire uniquely classifies rental properties under RSA 540:1-a. Restricted property landlords (larger buildings, non-owner-occupied) can only evict for enumerated good cause, including a tenant’s refusal to accept a properly noticed rent increase. Nonrestricted property landlords (owner-occupied buildings with 4 or fewer units, owners of 3 or fewer single-family homes) can terminate for any reason with proper notice.

2) MANUFACTURED HOUSING MEDIATION: Under RSA 205-A:6, if a rent increase in a manufactured housing park exceeds 15 per month, at least 51% of homeowners in the park may petition for mediation.

The park owner pays the mediator’s cost. The rent increase notice must include a disclosure of this right in 10-point bold-face print. 3) SERVICE OF NOTICE: Under RSA 540:5, notice of a rent increase must be served in hand or left at the tenant’s abode, or sent by certified mail. Improper service may invalidate the notice.

Understanding New Hampshire Rent Increase Laws

Whether a New Hampshire rent increase is legal depends on the cap (if any), the notice given, and whether the increase is retaliatory. New Hampshire rent increase laws protect tenants from surprise hikes by requiring a minimum notice period before any increase takes effect.

If you believe a New Hampshire rent increase violates these rules, document the notice you received, check the math against the cap, and contact your local housing authority or legal-aid office.

Knowing the New Hampshire rent increase rules before your lease renews puts you in a much stronger position.
