Franklin County, KY Building Setbacks & Zoning: Setback Rules (2026)

Setbacks in unincorporated Franklin County, Kentucky are set district by district in the zoning chapter adopted by the Fiscal Court (Ord. 8, passed 10-23-1987). Section 155.135(E) covers the AG Agricultural District under the heading Bulk density and height. The table prints Minimum front yard 50 ft., Minimum rear yard 25 ft., Minimum side yard 25 ft. and Minimum street side yard 30 ft. It adds Minimum lot frontage 200 ft., Minimum lot size 5 acres and Minimum spacing between any 2 dwellings on same tract 30 ft.

The residential districts print smaller yards. In the RR Rural Residential District (§ 155.136) the table shows a 35 ft. front yard, 40 ft. rear yard, 10 ft. side yard and 22 ft. street side yard, with a note that the front yard is measured from the property line at the right-of-way. The RA district (§ 155.137) prints a 30 ft. front yard, 40 ft. rear, 10 ft. side and 20 ft. street side. The RB district (§ 155.138) prints 25 ft. front, 25 ft. rear, 8 ft. side and 15 ft. street side, and the RC district (§ 155.139) prints 15 ft. front, 25 ft. rear, 6 ft. side and 10 ft. street side.

Two other provisions affect where a structure sits. Section 155.135(G) exempts land used solely for agricultural purposes from yard and location requirements for agricultural buildings, but says setback can still be required for the protection of existing and proposed roads, streets and highways. Section 155.334 sets parking back from public right-of-way lines by at least one-half of the setback requirements of the applicable zone, except for single-dwelling residences, and requires parking to the side or rear of a structure to sit back from lot lines at least one-half of the side or rear yard requirement. The Board of Zoning Adjustments hears variance requests.
