All districts
Front or street side yards: fences and freestanding walls are capped at 3.5 feet; visually transparent, nonopaque fences over 3.5 feet may be allowed through modification by the hearing officer. Interior side or rear yards: 6 feet maximum in residential districts, 8 feet maximum in commercial, mixed use, and industrial districts. Rural districts: up to 8 feet on interior lot lines for screening and livestock fencing. One entry gateway, trellis, or similar entry structure is permitted in the required front or street-facing side yard per lot, up to 10 feet in height and width, with no solid obstruction wider than 2 feet between 3 and 10 feet high. Prohibited/restricted materials: barbed wire, razor wire, embedded glass shards, ultra barrier, electrified, and other hazardous fencing are prohibited in residential and open space districts, and on commercial/mixed-use street frontages and industrial district perimeters. Chain link fencing may be used only when not visible from off site (or, outside residential districts, as temporary construction fencing or with zoning administrator approval); chain link is not permitted in any street-facing yard in commercial or mixed-use districts. Corral fences for livestock may sit in the required front yard in rural districts, must be at least 67 percent open, cannot use chain link or barbed wire, and are capped at 6 feet. A fence height waiver from the hearing officer may allow up to 6 feet in front/street side yards and 10 feet in interior side/rear yards. Fences must respect the visibility triangle at intersections and driveways (MCC 18.80.150), capped at 3 feet within the sight triangle absent a waiver.
