Fence Installation Permits in Renton

Local Rule

Renton Community and Economic Development Department,

Renton Municipal Code 4-4-040 caps residential fence, hedge, or retaining wall height at 8 feet overall; within any part of the required front yard setback the limit drops to 48 inches (4 feet), and within the clear vision area at intersections it drops further to 42 inches. A Special Administrative Fence Permit lets a property owner request a modified height limit on corner lots or lots with multiple street frontages. The specific height under which the city waives a standard building permit for an ordinary fence could not be independently confirmed from a machine-readable city source; a commonly cited placeholder for the area is 6 feet. Confirm the exact no-permit threshold with Community and Economic Development at (425) 430-7200 before relying on it.

How This Compares to King County

Renton's own rule is shown above (No permit under 6 sqft). Here is the separate rule that applies at the county level, for context:

City of Seattle / King County

In King County (Seattle) you can build a fence up to 8 feet without a permit as long as no masonry or concrete section exceeds 6 feet; taller fences, or any in a flood-prone or critical area, need a construction permit. Zoning limits front-yard fences to 4 feet and solid side/rear fences to 6 feet (open designs allowed up to 8). Unincorporated King County caps no-permit fences at 6 feet. Washington's Good Neighbor Fence Act covers shared costs.
