How Much Does a Fence Cost in Seattle? (2026 Guide)

The main cost factors for fence installation in Seattle: 1. Material — Cedar is the most popular and most affordable natural option. Vinyl costs more upfront but nothing over 25 years. Composite fencing is the premium maintenance-free option. 2. Height — A 6' fence is standard and typically requires no permit. An 8' fence costs 20–30% more and requires a permit in most Seattle cities. 3. Terrain — Flat lots install faster. Sloped lots require "racking" (angling the fence with the terrain) or "stepping" (stair-step sections). Stepped fencing adds 10–20% to cost. 4. Length — Longer fences have lower per-linear-foot costs due to amortized mobilization. 5. Demolition of existing fence — Removing an old fence adds $3–$8/LF to the project.
