New Hampshire has no statewide rent control or caps on rent increases in 2026, allowing landlords to raise amounts freely while requiring advance written notice. Tenants benefit from protections against mid-lease changes and retaliatory hikes under RSA 540-A.
Notice Requirements
Landlords must provide 30 days’ written notice for month-to-month tenancies before hikes. Fixed-term leases prevent increases until renewal, unless escalation clauses exist. Mobile homes require 60 days’ notice.
No Limits on Increases
No statutory cap or frequency restriction—landlords base hikes on market rates, with some towns like Lebanon/Hanover imposing local limits (check municipal codes). Raises cannot violate implied warranty of habitability or retaliate against complaints.
Prohibited Actions
Mid-lease hikes without agreement are invalid; discriminatory increases breach Fair Housing laws. Tenants can reject by vacating post-notice.
Recourse Options
Challenge improper notices via written response or District Court; recover damages if retaliatory. Written leases offer best stability.
