Regulatory framework
The code baseline for Sullivan County.
New Hampshire state baseline under RSA 155-A: 2021 IBC, IEBC, IPC, IMC, ISPSC, and IRC; 2018 IECC; 2023 NEC; and state-approved amendments. Municipalities administer local enforcement and any confirmed local amendments.
Inspection lane
Contact the town or city building official for the project location. RSA 155-A assigns plan review, permit issuance, inspection, and occupancy functions to an authorized local enforcement agency; a state-fire-marshal fallback may apply where no local mechanism exists and the municipality requests it.
