Do I need a permit for solar panel installation in Goodlettsville?
Yes. In Tennessee, solar panel installation generally requires a permit, and Goodlettsville is no exception.
Rooftop solar typically needs both structural (building) and electrical review; utility interconnection approval is a separate process from the local permit. Requirements vary by jurisdiction, so verify submittal details with your local codes department (Nashville, Memphis/Shelby, Knox) or the state issuing agent before installation. For projects on the Davidson County side of Goodlettsville, you first obtain the building permit from the City of Goodlettsville and then obtain the electrical permit from the Metro Nashville Codes Department, so a solar install involves two departments. The City of Goodlettsville will not issue a certificate of occupancy until all Metro Nashville permits have passed their final inspection, so schedule both the city and Metro inspections. Tennessee generally requires a licensed contractor for construction valued at $25,000 or more, and in Davidson County a Home Improvement license can apply to smaller residential jobs, so confirm your installer is properly licensed and bonded.
