Williamson County, TN Food Trucks & Mobile Vendors: Food Truck Permits (2026)

05(D)(13)(b) of the Zoning Ordinance sets the operational requirements for a food truck on private property in Williamson County. Each Temporary Use Permit is valid for six months per calendar year, and the ordinance requires the truck to go through Minor Site Plan review under Article 6 every time an operator requests a permit period, so approval does not roll over automatically from one term to the next. Before a permit issues, the operator needs written permission from the property owner acknowledging familiarity with the food truck regulations and accepting joint responsibility, along with the operator, for any violations, and a written contract between the owner and operator has to be filed with the county and must require compliance with the regulations.

, the truck must leave the property every day outside those hours, and it may never be stored overnight on a public street or sidewalk. The Temporary Use Permit itself must be displayed to the public at all times the truck is operating, and the vehicle's required signage must be permanently affixed to or painted on the truck rather than posted separately. State and local licensing still applies on top of the zoning permit: the ordinance requires the truck to be licensed, equipped and operated under all local, state and federal rules that apply, including Health Department food-safety regulations.

Two further operating limits round out the permit conditions: no amplified sound is allowed at the site, and no outdoor seating for dining may be set up in connection with the truck. Only one food truck is allowed per property under a single permit, and adding a second truck requires Special Event approval instead.
