Summary
Sumner County caps residential fences at 8 feet in side, rear, and even transparent front yards, while commercial and industrial fences can rise to 15 feet, dropping to 6 feet between a building and the street. Tennis court fencing tops out at 12 feet and baseball backstops at 16 feet, all measured from finished grade, not from atop a berm.
1. In any residential district, no fence or wall shall exceed eight (8) feet in height in side and rear yards. Fences in front yards may be eight (8) feet in height provided that fences within the required front yard (i.e. front setback) be of transparent construction (i.e. split rail, picket, chain link, etc.). Tennis court fencing shall not exceed twelve (12) feet, and baseball backstops shall not exceed sixteen (16) feet. In commercial or industrial districts, no fence or wall shall exceed fifteen (15) feet in height. Between the principal building and the street right-of-way, no fence or wall shall exceed six (6) feet in height. The height of such fences and walls shall be measured from the finished grade to top of the individual sections. The finished grade shall not include measurements from the top of a berm.
Full Breakdown
Section 1101, Subsection B(1) of the Zoning Resolution sets the county's fence and wall height ceiling: in any residential district, side and rear yard fences may not exceed 8 feet, and a fence within the required front setback may also reach 8 feet, but only if it is of transparent construction such as split rail, picket, or chain link, so solid privacy fencing is barred from front yards. Recreational exceptions run higher: tennis court fencing may reach 12 feet and baseball backstops 16 feet. Commercial and industrial fences and walls may rise to 15 feet, except between the principal building and the street right-of-way, where the limit drops to 6 feet so sightlines to the business are preserved.
Height is always measured from finished grade to the top of the fence section, and Subsection B(1) specifically bars using a berm's top as the measuring point, closing off a common workaround for exceeding the cap. Subsection B(9) layers a second restriction on top of the height rule: fences, walls, or vegetation may not interfere with the Vision Triangle, defined in Appendix A, at any public or private street, alley, or driveway, so a corner-lot fence that otherwise meets the 8-foot cap can still be cited if it blocks sightlines into the intersection. Posts must be set at least 2 feet deep, per Subsection B(2).
Violations & Fines
An oversized, misplaced, or vision-triangle-blocking fence violates Section 1101 of the Zoning Resolution and is enforced through the Director of Building Codes, who can order repair, replacement, or removal under Subsection B(8) for a fence that is deteriorated or out of compliance. Beyond that order, Section 1413, Subsection D makes the violation a misdemeanor with a fine plus costs, and each day of noncompliance counts separately.
