Kent, WA Fence Regulations: Material Restrictions (2026)

Kent City Code 15.08 does not rigidly dictate approved fence materials in residential zones but restricts hazardous materials based on zone. In R-1 through R-8 residential zones, common materials including cedar wood, vinyl, aluminum, wrought iron, composite, and chain-link are all permitted subject to the 4-foot front and 6-foot side-rear height limits. Barbed wire is not allowed below 6 feet in residential zones; in industrial zones it may top a 6-foot fence with strand wires extending above. Electric fencing for pet containment is not permitted in residential zones except for invisible (underground) dog-containment systems, which are allowed as long as visible warning signage is posted. Razor ribbon and concertina wire are restricted to industrial zones serving critical infrastructure with a conditional use permit. Temporary orange construction or silt-fencing on active permit sites is exempt. HOAs may further restrict to specific materials or colors (commonly cedar board-on-board or tan vinyl) under private covenants.
