Do you need a permit for Pool Construction in Grafton County?
In New Hampshire, a Pool Construction requires a building permit.
Any pool more than 24 inches deep requires a permit and a compliant safety barrier at least 48 inches high with self-closing, self-latching gates (IRC R326 / ISPSC). Prefabricated pools under 24 inches deep are exempt. Plans are reviewed under the Statewide code (IRC 2021); apply through Grafton Building Inspector before work begins.

Code Compliance & Inspections
