HVAC Installation · Bonner County, Idaho

Permit required

In Idaho, a HVAC Installation requires a mechanical permit.

Installing or replacing HVAC equipment requires a mechanical permit and inspection; even a same-size, same-location swap generally needs one. Routine maintenance and minor repairs are exempt, and a gas-to-heat-pump conversion also requires an electrical permit. Plans are reviewed under the Statewide code (IRC 2024); apply through Bonner County Planning Department before work begins.
