San Bernardino County, CA Fence Regulations: Material Restrictions (2026)

San Bernardino County's Development Code Section 83.06.070 (Prohibited Fence Materials) restricts fence materials by region and zoning district in the unincorporated area. Permanent chain link fencing (and similar materials like chicken wire or hog fencing) is prohibited in residential districts in the Valley Region, except where it is not visible from the public right-of-way, or does not extend in front of the primary structure and is camouflaged with plantings; chain link is allowed for temporary uses, allowed in the Mountain Region when combined with other materials (such as split-rail) and camouflaged, and is not prohibited at all in the Desert Region. Barbed wire and razor wire are prohibited in residential districts and adjacent to public rights-of-way in commercial and industrial districts; barbed, razor, or other sharp-pointed material may only be used if it is at least 6 ft above ground level. Tarp fencing is prohibited in all land use zoning districts. Electrified fencing or wires - in conjunction with any fence, wall, roof, or hedge, or by itself along property lines - is prohibited in any district unless required by law or as a condition of approval, though it may be allowed within a parcel's interior if buffered from other properties by a separate barrier. These prohibitions apply alongside the height limits in Section 83.06.030.
