Williamson County, TN Fire Regulations: Fireworks (2026)

05(D)(4) of the Williamson County Zoning Ordinance regulates fireworks sales as a temporary use, separate from the general fireworks-safety provisions of state law. A sales structure must be set back at least 250 feet from any residential property line and at least 500 feet from any other structure being used for fireworks sales, spacing meant to keep competing stands and nearby homes clear of the activity. The Temporary Use Permit authorizing the sale is valid for only 15 days within any single six-month period, and the ordinance ties that window to specific seasons: sales are limited to times around New Year's Day and the Fourth of July, so a stand cannot operate outside those two holiday clusters.

Beyond the site standards, the ordinance layers on paperwork: the operator must hold a business license before selling fireworks, and must submit a notarized statement from the property owner identifying the sales location, the exact duration the sale is authorized, and confirming the owner's consent to host it. Because the standard sits in Article 11's temporary-use provisions, each fireworks stand is also subject to Minor Site Plan review under Article 6 every time a permit is requested, meaning a seller cannot simply renew a prior approval without a fresh site plan for that selling period.

An application for the use has to reach the Planning Department no later than 30 days before the first day the operator intends to open. Taken together, the setback, licensing, seasonal window and site plan requirements make Williamson County's fireworks sales standard considerably more restrictive than simply following the underlying state fire-safety statute; a seller who is legal to sell fireworks under state law can still be denied a stand location in the county if the site plan or setbacks fail.
