Do I Need a Permit to Build a Fence in Bellevue, WA?

Bellevue’s fence rules are notably permissive compared to many cities: the permit threshold is 8 feet, meaning a standard 6-foot cedar privacy fence in the side or rear yard requires no building permit at all. The zoning rules on height and front-yard placement still apply, but the permit process is cleaner than most.

Bellevue WA fence rules — the basics

Bellevue's 8-foot no-permit threshold for fences is one of the more permissive in the Pacific Northwest. The building permit exemption covers "light-frame construction fences not over eight feet in height" — meaning a standard residential privacy fence built of wood or similar light materials at or under 8 feet can be constructed without a building permit from Bellevue's Permit Center. Fences over 8 feet require a permit and additionally may not be located within any required front, rear, or side-yard setback.

While fences up to 8 feet don't require a building permit, they must still comply with Bellevue's zoning height and placement regulations. The key rule: fences exceeding 4 feet, 6 inches in height may be located anywhere except within the required front-yard setback. This means a 6-foot side or rear yard fence is perfectly acceptable without a permit, but that same 6-foot fence cannot be placed within the front-yard setback. The front yard is limited to a maximum fence height of 4 feet, 6 inches (4.5 feet). Exceptions to the 4.5-foot front-setback limit exist for fences perpendicular to the right-of-way for screening purposes, fences on one side of a corner lot, and certain chain-link fences in specific zones — the land use planner at Bellevue's Development Services can confirm whether your property qualifies for an exception.

Fences near driveways and street intersections face sight-obstruction restrictions under BCC 14.60.240 and 14.60.241. These restrictions vary by intersection type and are designed to maintain driver visibility. If your planned fence location is near a driveway exit or street intersection, contact the Bellevue Transportation Department for guidance before finalizing fence placement. Building a fence that creates a sight hazard is both a code violation and a genuine safety risk.

Bellevue's specific note on walls: a wall that is not used for retention of soil but solely prevents entry to an area is considered a fence for regulatory purposes and is subject to fence height and placement requirements. A masonry wall used purely for privacy functions as a fence under Bellevue's code; a wall that retains soil is a retaining wall subject to separate permit requirements (building permit required for retaining walls over 4 feet in height measured from bottom of footing to top of wall).

Fence materials in Bellevue's Pacific Northwest climate

Bellevue's wet winters and mild temperatures create a moisture-dominated durability environment for fence materials. Western red cedar is the quintessential Northwest fence material — its natural oils provide excellent rot resistance in the perpetually damp Pacific Northwest climate, and its reddish color weathers to a distinguished silver-gray. Pressure-treated fir or pine provides a more economical structural option for fence posts and rails. Composite and PVC fencing are gaining market share for their virtually maintenance-free performance in the rainy climate. Hardware must be stainless steel or hot-dipped galvanized; coated or zinc-plated hardware rusts through within a few years in Bellevue's moist conditions. Post depth in Bellevue's mild climate is determined by stability and drainage considerations rather than frost depth; 24–30 inches of embedment in concrete provides a stable base for a 6-foot privacy fence.
