The Zoning Ordinance for Unincorporated Williamson County

The Williamson County Zoning Ordinance was adopted on May 14, 2012 and became effective on January 1, 2013.  The Zoning Ordinance governs all types of development within the unincorporated areas of the County.  Specifically, the Zoning Ordinance:

  • Establishes a variety of Zoning Districts, which are applied to land within the unincorporated County;
  • Outlines the types of land uses (e.g. single-family dwellings, offices, retail, etc.) that are allowed within those Zoning Districts;
  • Contains specific requirements related to such things as residential density, open space, building setbacks, parking, landscaping, and other aspects of new development; and
  • Outlines the specific procedures for the review and approval of development proposals.

Please note that the Zoning Ordinance is an evolving document.  As such, we encourage you to check with the Planning Department for information regarding any changes or amendments to this document.
