Do I need a permit for solar panel installation in Forest Hills?
Yes. In Tennessee, solar panel installation generally requires a permit, and Forest Hills 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. Forest Hills treats roof alteration as permit work and issues the building permit itself, but the electrical portion of a solar install is a trade item; the City states that all trade inspections including electrical are conducted by Metro Nashville, so plan for both a City building permit and a Metro Nashville electrical permit. The City Building Inspector completes the building inspections and does not accept third party verifications, and the system must meet the City adopted 2018 International Residential Code and the electrical code. Tennessee requires a state contractor license for larger residential work, so confirm your installer holds the correct Tennessee classification and monetary limit before signing.
