Seattle Fence Permit Guide

Seattle fence permits depend heavily on height, masonry/concrete elements, and flood-prone locations.

Permit takeaway

Seattle says a fence generally does not need a permit if it is eight feet high or lower and does not include masonry or concrete pieces over six feet, unless it is in a flood-prone area.

Zoning and placement

Height, materials, and flood-prone location should be checked before assuming the fence is exempt.

Building and trade review

Taller fences need a construction permit, and Seattle notes that most fences use a construction subject-to-field-inspection permit.

Call before applying when

Call before applying if the fence is taller than eight feet, includes masonry/concrete, is in a flood-prone area, or is tied to a retaining wall.
