Complete·7/9/26

New Hampshire HB1079 allows accessory dwelling units to be built within or attached to certain non-conforming structures.

New Hampshire HB1079 amends RSA 674:72, XI to allow municipalities to permit accessory dwelling units in existing structures, including detached garages, regardless of current dimensional requirements. The bill defines "existing structure" as any structure present before July 1, 2025, and exempts these structures from future zoning changes if they meet certain development criteria.
