Building in Smyrna
Smyrna is a town by charter, though with 63,321 residents by the Census Bureau’s 2025 estimate it’s bigger than most Tennessee cities, and at the 2020 Census it was the largest town in the state. Permits come from the town’s Building Safety department on South Lowry Street, which adopted the 2024 International Codes on April 15, 2026.
Fences stay out of the front setback
Smyrna’s zoning ordinance keeps fences out of the front-yard setback, apart from short decorative runs of wood, wrought iron, vinyl or brick no taller than 3 feet and no more than 10 feet long in all. Barbed, razor and chicken wire are banned in residential districts, and easements stay clear unless the town approves. A fence over 7 feet needs a building permit; a shorter one still goes through the Public Works fence application with a site plan. On a corner, nothing between 3½ and 10 feet tall can stand within 75 feet of the intersection, measured along the street centerlines.
Decks and outbuildings
Starting a deck takes a site plan sent to the town’s permit office. Every accessory structure, a pavilion included, needs a building permit and has to meet the setbacks. Its size scales with the lot: 600 square feet on a lot under 10,000 square feet, up to 3,500 on a lot over 5 acres. Beside a one-story house, the roof peak is held to 18 feet.
Driveways and Front Street
No curb can be cut for a driveway without written approval from the Smyrna Street Superintendent, plus a TDOT permit on a state highway. In the Front Street Historic District, the old downtown, work needs a certificate of appropriateness from the Historic Zoning Commission before the building permit. Front-yard fences aren’t allowed there, and chain link, vinyl and concrete block are ruled out wherever the street can see them.
