Ravensdale Fence Regulations: Material Restrictions Rules (2026)

King County Code Title 21A does not generally limit the material used for residential fences. Wood, cedar, vinyl, composite, aluminum, wrought iron, and chain link are all permitted at code-compliant heights. Barbed wire is prohibited in residential zones (RA, R, UR) except as the top strand on fences surrounding agricultural operations, public utilities, or industrial sites. Razor wire and concertina wire are generally prohibited in residential zones. Electric livestock fencing is permitted in agricultural zones (A) under KCC 21A and is subject to signage requirements per RCW 16.60.030. Where a fence abuts a public right-of-way or trail, materials must not create hazards such as protruding sharp ends or exposed fasteners. Corrugated metal, pallet wood, and similar improvised or salvaged materials are generally allowed on private property but may trigger property maintenance or junk vehicle code enforcement if they create a public nuisance. HOAs frequently impose stricter material palettes (wood-only, specific stain colors, or prohibitions on chain link visible from the street).
