The county Zoning Ordinance caps building height by district, usually measured in stories rather than feet. Most residential districts allow up to 3 stories; rural and agricultural districts set no height limit. Cities set their own caps.
Williamson County regulates height through Article 10 of its Zoning Ordinance under Tenn. Code Ann. §13-7-101. Unlike many codes that use a 35-foot ceiling, the county measures most districts in stories: a common cap is 3.0 stories for residential structures, with a few districts allowing 3.5 and some limited to 2 stories. The Rural Preservation and Voluntary Agricultural districts list height as "Not Applicable," reflecting the county's farm and large-lot character. Franklin, Brentwood, and the other incorporated cities apply their own height limits, and structures near the airport also face FAA notice rules.
The county building codes office and planning department enforce height limits with stop-work orders on over-height work. Legalizing an over-height structure requires a variance from the Williamson County Board of Zoning Appeals.
