Do I need a permit for solar panel installation in Nashville (Metro)?
Yes. In Tennessee, solar panel installation generally requires a permit, and Nashville (Metro) 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. Metro Codes lists new solar systems as requiring an electrical permit, so a residential solar install in Nashville needs a permit regardless of project size. Registered contractors apply and self-issue through the Metro ePermits portal, while an owner-occupant of a single-family home must apply through Codes using a notarized self-permit affidavit rather than the online system. Tennessee state law 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.
