Permits are required for new and renovation construction based on the provisions of the current NH State Building Code and applicable amendments.

The following permits are issued through this program:

  • Building Permit
  • Mechanical Permit (fuel gas): For all work subject to state licensing requirements as identified in RSA 153:27
  • Mechanical Permit (non-fuel gas): Work not subject to state licensing requirements including ductwork
