Jessamine County, KY Fence Regulations: Height Limits (2026)

Section 153.062(J) of the Jessamine County Code, part of the subdivision regulations the Planning Commission administers, protects drivers' sight lines at street corners. Inside the sight distance triangle formed at corners by the street curbs or edge of pavement, nothing in the way of fences, walls, hedges or other landscaping is permitted to obstruct visibility for a height of 10 feet above the ground or finish grade. The section prints no separate front, side or rear fence height figure; the 10-foot figure is a visibility clearance measured from the ground.

The size of the triangle comes from the speed limit. It is measured from a point 15 feet back from the intersecting corner, diagonally to a point determined by the speed limit, then along the road edge of pavement back to the corner. The table prints 484 feet for 55 mph, 396 feet for 45 mph, 308 feet for 35 mph, 220 feet for 25 mph and 132 feet for 15 mph. Each distance is the feet traveled in 6 seconds at the speed limit, and the distances apply to all legs of the intersection.

The rule carries two exceptions. It does not apply in a city central business district, and where extraordinary physical conditions necessitate a retaining wall, the Planning Commission must approve that wall. Where visibility has to be created, the code calls for excavating if necessary.

The same subsection reaches signs and grades near the corner. A ground-mounted identification sign cannot be placed within the sight distance triangle, and a pole sign proposed there needs at least 10 feet from the ground to the bottom of the sign, or more if the topography warrants. Grades at street intersections are limited to 2% for a distance of 75 feet from the intersection of the centerlines, and all street intersection corners are rounded by curves of radii of at least 25 feet.
