New Hampshire: Rent Increase Notice Requirements

New Hampshire's rent-change framework

New Hampshire frames its general rent-change rule through the good-cause
eviction statute. Under RSA 540:2(IV), a tenant's refusal to agree to a
change in the existing rental agreement calling for higher rent constitutes
good cause for eviction under paragraph II(e) only if the landlord gave written
notice of the increase's amount and effective date at least 30 days before that
effective date.

That structure matters. The statute speaks of the tenant's refusal to agree to
a change, not of notice automatically rewriting the agreement. The landlord
must satisfy the written amount, effective-date, and 30-day conditions before
relying on refusal as good cause within the restricted-property framework.

For “nonrestricted property” defined in RSA 540:1-a(I), § 540:2(I) permits
termination by a statutory notice to quit without the restricted-property
good-cause list. The cited statutes state no separate general rent-increase
notice period for that category; termination notice is outside this topic.

Amount, frequency, and fixed terms

RSA 540:2(IV) sets no maximum percentage or formula and no separate annual
frequency limit. It regulates the notice needed before refusal can become an
eviction ground. A local rule may add requirements.

The section also does not state that 30 days' notice overrides rent promised
for a fixed term. A fixed lease's duration and adjustment language must be read
separately. Renewal pricing and a proposed consensual change are different from
a unilateral mid-term charge.

Coverage of the good-cause framework depends on the property. RSA 540:1-a
defines “restricted property” and excludes the listed small-landlord,
owner-occupied, and foreclosure categories as “nonrestricted property.” Those
definitions affect the eviction protection, not the existence of a statewide
percentage cap.

Common questions

What must a New Hampshire increase notice say?

It must be written and state both the amount and the effective date of the rent
increase. The landlord must provide it at least 30 days before that date to use
the tenant's refusal as good cause under RSA 540:2(IV).

Does New Hampshire cap the increase?

No general statewide percentage or CPI formula appears in the governing
section. The statute regulates notice and the consequence of refusing the
proposed agreement change.

Does the statute award special damages for a bad notice?

RSA 540:2(IV) states no rent-increase-specific damages amount. If the
landlord files for possession, the tenant may contest whether the asserted good
cause and statutory notice conditions are satisfied.
