Do I need a permit for hvac replacement or installation in Goodlettsville?
Yes. In Tennessee, hvac replacement or installation generally requires a permit, and Goodlettsville is no exception.
Replacing a furnace, air handler, or condenser (a change-out) generally requires a mechanical permit; new gas or electrical connections may require additional trade permits and inspections. Confirm submittal and inspection details with your local codes department or the state issuing agent, as thresholds and forms differ by jurisdiction. For the Davidson County portion of Goodlettsville, gas/mechanical permits are obtained from the Metro Nashville Codes Department, so an HVAC change-out is permitted through Metro Nashville rather than the city Building Department. The City of Goodlettsville will not issue final approval or a certificate of occupancy until all Metro Nashville permits have passed their final inspection, so confirm both offices where a broader project is involved. Confirm with the Goodlettsville Codes office at 615-851-3741 and Metro Nashville Codes at 615-862-6500 whether your specific unit replacement needs a permit before starting.
