Williamson County, TN Garage & Yard Sales: Frequency, Duration & Permits (2026)

04(D)(15) of the Williamson County Zoning Ordinance treats a yard sale as an accessory use tied to a residential property, alongside the 15 other accessory uses the ordinance lists in the same subsection, from accessory dwelling units to home occupations. The rule itself is short and numeric: a yard sale is permitted only if it runs no more than three consecutive days within a 90-day window, and a single property cannot host more than four such sales in a calendar year. Reading the two caps together, a household could run one three-day sale roughly every quarter, but stacking sales back-to-back or holding a fifth event in the same year exceeds the accessory-use allowance and takes the activity outside what the ordinance permits by right.

Because the standard sits in Article 11's accessory-use table rather than in the temporary-use permit article, the ordinance does not spell out a separate permit application for a yard sale the way it does for produce stands or fireworks sales; the frequency and duration caps are the entire substantive standard in this subsection. 01(A) of the ordinance, which states that the Ordinance applies to all areas within the unincorporated area of the County. A yard sale hosted inside Franklin, Brentwood, Spring Hill, Fairview or Nolensville falls under that city's own code, not this county provision.
