New Hampshire Rent Increase Notice (RSA 540:2)

New Hampshire imposes no cap on residential rent. Under RSA 540:2, II, a "tenant's refusal to agree to a change in the existing rental agreement calling for an increase in the amount of rent shall constitute good cause" for eviction only where the landlord "provided the tenant with written notice of the amount and effective date of the rent increase at least 30 days prior to the effective date of the increase." There is no separate statute requiring a notice of increase by itself; the 30-day requirement operates through the eviction-for-cause framework, so an increase a tenant rejects cannot be enforced by eviction without that 30-day written notice. The increase notice should be served in the manner used for a notice to quit (RSA 540:5).

No specific statutory penalty. An increase a tenant rejects cannot support an eviction for good cause unless the landlord gave the required 30-day written notice (RSA 540:2, II).
