🏊 Swimming Pool / Spa permit in New Hampshire

An in-ground or above-ground swimming pool or spa, including decking and barrier fencing. Here is the New Hampshire-specific rule: who issues it, typical fees, timeline, go / no-go, and the official source to verify.

Verify locally. New Hampshire enforces a MANDATORY statewide building code (2021 IRC/IBC and related codes with NH amendments under RSA 155-A, effective July 1, 2024). Permits are issued by local building departments; towns without a local inspector are served by the State Fire Marshal’s Office (NH Division of Fire Safety). Local ordinances may be stricter than the state minimum. Rules below are New Hampshire-level guidance drawn from official sources — always confirm with the issuing building department before starting work. See the county permit authorities to find the right office.
