El Dorado County, CA Fence Regulations: Material Restrictions (2026)

070 flatly prohibits "concertina wire, serpentine wire, barbed wire, razor wire, and other similar fencing materials capable of inflicting significant physical injury" anywhere the general fence rules apply. The ban is not absolute: a property owner can apply for a Minor Use Permit under Article 5 of Title 130 to install one of these materials, but only by showing the fencing is reasonably necessary to protect persons or property and will not create a safety hazard for anyone lawfully present nearby. Even with an approved permit, the material can never protrude into or over a public right-of-way.

The Section carves out two categorical exceptions that need no permit at all: fencing installed under a court order, and fencing used for animal husbandry or grazing operations, recognizing that ranchers and farmers in the county's agricultural and resource zones rely on barbed wire for livestock containment. Outside those two carve-outs and a granted Minor Use Permit, installing any of the prohibited materials, including on top of an otherwise compliant fence or wall, is treated as a straight code violation rather than a setback or height problem, because the prohibition applies regardless of where on the property the fence sits.
