Siskiyou County, CA Fence Regulations: Fence Requirements (2026)

Siskiyou County does not maintain a standalone fence ordinance within its zoning code (Title 10, Chapter 6). Article 15, which covers general provisions, conditions, and exceptions, addresses building height and yard exceptions but does not set fence-specific design, location, or material standards. As a result, the main requirements for a fence in unincorporated Siskiyou County are procedural and code-based: all proposed fencing is subject to Planning Division approval and to the applicable standards set forth in the county ordinance, a building permit is required for fences above the permit-exempt height (the County Building Division uses six feet; the California Building Code exempts up to seven feet), and fences must not conflict with required yards, easements, or vision clearance at driveways and intersections. Fences that serve as swimming pool barriers must meet separate state pool-safety standards. On agricultural and rural parcels, fencing is common for livestock and boundary purposes and is generally treated as a permit-exempt accessory improvement when within the height threshold. Because the code does not prescribe specific fence materials or setbacks, owners should verify their parcel's zoning district, any setback applicable to structures, and corner or driveway sight-line needs with the Planning Division before installation. When the county code is silent, statewide building and safety codes provide the controlling minimums.
