New Hampshire Prohibits Local Rent Control Statewide

New Hampshire does not authorize rent control at the state or local level. RSA 540 governs the landlord-tenant relationship, including notice and eviction procedures, but does not cap rents or rent increases. Without enabling legislation, New Hampshire municipalities lack authority under Dillon's Rule principles to enact rent control ordinances. Landlords may raise rent at the end of a lease term with proper 30-day notice for tenancies-at-will under RSA 540:3. The state's strong property rights tradition has consistently rejected rent control proposals. RSA 354-A prohibits discriminatory rent practices, but lawful market-based pricing is not regulated.

No rent control violations exist; landlords following RSA 540 notice rules face no rent-cap penalties. Discriminatory rent increases may violate RSA 354-A with civil penalties.
