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

The Siskiyou County Zoning Ordinance does not contain provisions restricting fence materials such as wood, chain link, wire, vinyl, masonry, or barbed wire for general residential and rural fencing. Article 15 of Chapter 6 deals with height and yard exceptions but does not regulate fence materials or appearance. Because the county code is silent on materials, owners generally have flexibility in their choice of fencing, subject to several practical limits. All proposed fencing is subject to Planning Division approval and applicable ordinance standards, so a project that raises sight-line, easement, or zoning concerns may need adjustment. A fence taller than the permit-exempt height (six feet per the County Building Division, seven feet under the California Building Code) requires a building permit and must meet structural requirements for the chosen material, particularly for masonry or block walls, which are engineered as walls rather than simple fences. Fences that act as swimming pool barriers must comply with state pool-safety standards governing gaps, openings, and gate hardware regardless of material. On agricultural parcels, wire and barbed-wire fencing for livestock is common and is generally permissible. Owners considering masonry walls, electric fencing, or fences near roadways should confirm any structural, drainage, or vision-clearance requirements with the Planning and Building Divisions before installation.
