How Tall Can a Fence Be Without a Permit in Washington?
Washington doesn't tie its fence permit to a single height cutoff — the permit follows the scope of work rather than a threshold. Height still matters, just as a zoning cap rather than a permit line: on record, 3.5 feet in front yards and 7 feet in rear and side yards. Build above those caps and you're into variance territory, not just a permit. Confirm your lot's exact limits with the Department of Buildings, especially on corner lots where sight-line triangles cut into what you can build.
Do You Need a Permit to Build a Fence in Washington?
Plan on it — Washington lists fence work as permit-required, with fees typically in the $36.30–$150.00 range through the Department of Buildings. The upside of the process: the review checks your height, setbacks, and corner visibility before you build, which is far cheaper than moving a finished fence. HOA and deed restrictions apply on top of city rules, so clear both before ordering materials.
