Imperial County, CA Fence Regulations: Material Restrictions (2026)

Imperial County restricts certain fence materials in unincorporated areas under Title 9, Division 4, Chapter 3 of the Land Use Ordinance. Barbed or razor-edge wire is prohibited in all residential zones, or on property abutting residential areas, so a homeowner in or next to a residential area cannot top a fence with barbed or razor wire. Electrified fences are prohibited in all zones except for use in animal containment in the 'A' (agricultural) zones, or as security fencing at Federal, State or County institutions. This recognizes Imperial County's heavy agricultural base, where electric fencing is commonly used to contain livestock on 'A'-zoned land, while keeping such fencing out of residential neighborhoods. The ordinance also prohibits fences built from junk or improvised materials: tires, cans, broken glass, used car components, vehicles or other similar products are not allowed, and fences must be built of approved fencing or construction materials. Standard approved materials include wood, stucco, wrought iron and chain link (under 6 feet in any zone), and properly engineered masonry. These material restrictions operate alongside the height and sight-distance limits, so even an otherwise-approved material must still meet the front-yard and corner-lot height rules. Property owners in agricultural zones who rely on barbed or electric fencing for livestock should confirm their parcel's zoning and any abutting residential use before installing such fencing.
