Nashville, TN Permit Requirements: Shed & Outbuilding Permits (2026)

Nashville's Department of Codes and Building Safety requires building permits for sheds and carports that are 10 feet by 10 feet (100 square feet) or larger. Smaller sheds may be exempt from building permits but must still comply with zoning setback requirements. All sheds and accessory structures must be placed within the required setbacks for the property. Utility sheds and similar accessory structures cannot be converted to or used as living space. If a shed includes electrical wiring, it requires an electrical permit regardless of size. Plumbing and mechanical work also require separate trade permits. Sheds must comply with the adopted building code for structural requirements. Pre-fabricated and kit sheds still must meet all zoning and setback requirements. Nashville's Building Permits Central provides guidance on residential accessory structures. Permit applications can be filed at the Metro Office Building at 800 President Ronald Reagan Way, Nashville TN 37210. The Codes department recommends contacting them before starting any project to confirm requirements.
