Columbia County, FL Fence Regulations: Height Limits (2026)

Section 4.2.12 of the Land Development Regulations tells property owners that fences, walls, and hedges are governed by two cross-referenced provisions: the curb-visibility standards in Section 4.2.26 and the floodway fencing rule in Section 8.16.2. Section 4.2.26.1 applies on every corner lot in every zoning district: nothing, fence, wall, hedge, landscaping, or structure, may block sightlines between two and one-half feet and six feet above the street centerline grade, measured within the triangle formed by the two street lines and a line connecting points 25 feet from the corner on each street.

Section 4.2.26.2 applies the identical two-and-one-half-to-six-foot obstruction band wherever a driveway curb break crosses a public right-of-way, using a tighter ten-foot triangle measured along the curb break and the right-of-way line. Outside those sight triangles, the county's definitions section treats solid, wire, and chainlink fences as exempt from the structural height limitations that apply to buildings, so a fence in a side or rear yard away from a corner or curb break is not capped by a numeric height table the way a building is.

Retaining walls are expressly carved out of the visibility rule under Section 4.2.26.3, and Section 4.2.26.4 allows trees in the clear space as long as foliage is trimmed within the prescribed heights. A fence built into the triangle in violation of Section 4.2.26 is treated the same as any other land development regulations violation and can be referred to the special magistrate under Chapter 2 of the county code.
