Do I need a permit for addition or structural alteration in Nashville (Metro)?
Yes. In Tennessee, addition or structural alteration generally requires a permit, and Nashville (Metro) is no exception.
Additions and structural alterations require a permit and plan review; expect separate trade permits for electrical, plumbing, and mechanical work tied into the project. Owner-builders may perform work on their own residence under TCA 62-6-103, but the permit, inspections, and code compliance are still required. Additions and structural alterations to a Nashville home require a Metro Codes building permit, and Codes notes you can include interior renovation of the existing home within a single addition permit. In a Metro Historic overlay district, the Metro Historic Zoning Commission must issue a preservation permit before Codes will issue the building permit. Tennessee state law generally requires a licensed contractor for work valued at $25,000 or more, and Davidson County is one of the counties where a Home Improvement license can apply to smaller residential jobs, so confirm licensing before hiring.
