In unincorporated Williamson County, the county Zoning Ordinance fixes minimum front, side, and rear yard setbacks by district under Tenn. Code Ann. §13-7-101. Franklin and Brentwood set their own inside city limits.
Williamson County zones the land outside its cities through the Zoning Ordinance adopted May 14, 2012, using the county power granted by Tenn. Code Ann. §13-7-101. Article 10 sets dimensional standards district by district, and the county leans heavily rural: the Rural Preservation District west of I-65 requires 5-acre lots with a 35-foot front yard, while the Voluntary Agricultural district demands 15-acre lots with 100-foot front and rear yards. Side yards range from about 5 feet on conservation lots to 50 feet on farm parcels. Inside Franklin, Brentwood, Spring Hill, and Nolensville, each city's own zoning controls, not the county.
The county planning department and building codes office enforce setbacks. Building into a required yard triggers a stop-work order and correction; relief comes only through a variance from the Board of Zoning Appeals.
