Subdivision Regulations Update

Click here to view the updated Subdivision Regulations

Staff has been working on an update to the Williamson County Subdivision Regulations (Regulations), which were adopted in 1994. Although the Regulations have been modified in various ways over the years, a wholesale update is needed at this time in order to:

1.    Ensure that the Regulations are consistent with the Zoning Ordinance;

2.    Ensure that the review procedures are consistent with current and best practices;

3.    Adjust certain standards that have resulted in numerous requests for variances/waivers, including right-of-way width, roadway grade, etc.;

4.    Better address Large Lot Easement Subdivisions by adding standards for private drives and adding a Preliminary Plat stage to the review process;

5.    Eliminate standards and procedures that have become obsolete; and

6.    Improve overall user-friendliness of the Regulations through modern formatting that is consistent with Zoning Ordinance formatting.


A Public Hearing regarding this update will be held by Williamson County Regional Planning Commission on May 13, 2021 at 5:30 PM in the Auditorium of the Williamson County Administrative Complex, 1320 West Main Street, Franklin TN 37064.
