Orange County, FL Fence Regulations: Material Restrictions (2026)

Section 38-1408 sets the material standard for every fence and wall built in Orange County's unincorporated area. Subsection (a) requires a fence to be uniform in construction, design, material, color and pattern, using a standard material conventionally used by the fence industry, so mismatched scrap materials fail before height is even considered. Subsection (d) then bans barbed wire, razor wire and electrically charged fencing outright on any residential or office-district building site. The sole exception is security fencing for public utilities, and even that is capped: no more than three strands of wire, no taller than eighteen inches of wire height, mounted at least six feet above grade.

Subsection (e) loosens the rule only in commercial and industrial districts, where barbed or razor wire can extend the top of a permitted wall or fence under the same three-strand, eighteen-inch limit, so long as the combined wall-and-wire height does not exceed ten feet. A residential or office lot that borders a commercial or industrial district can add barbed wire on that shared line only through a board of zoning adjustment special exception, and only with substantial competent evidence that the added security is warranted.

Agricultural districts get a separate carve-out: barbed wire and similar field fencing is allowed there, but only when used for actual agricultural purposes such as groves, grazing or boarding animals, not as general perimeter security. Subsection (f) adds a placement rule that applies everywhere: barbed or razor wire can never project outward over a sidewalk, street or other public way, or out over a neighbor's property line, no matter which district allows the wire. Walls and fences in office and residential districts are separately barred from incorporating broken glass, spikes, nails, barbs or similar injury-designed materials, a standard that operates independently of the wire ban.
