Building a fence can transform your property by adding privacy, security, and aesthetic value. However, in Seattle and most of the King County region, constructing or replacing a fence often requires navigating a complex permitting process. Understanding the city’s fence permit rules is crucial to avoid unnecessary delays, fines, or even having to tear down your newly constructed fence. Terreworks, with our extensive experience in landscape design and permitting, is here to guide you every step of the way.
When Do You Need a Fence Permit in Seattle?

In Seattle, not all fences require permits, but it depends on the height, location, and purpose of the fence. Here are some key points to keep in mind:
- Residential Fences Under 6 Feet: Generally, fences that are 6 feet or shorter do not require a permit unless they are located in specific zoning areas or near environmentally critical areas (ECAs).
- Fences Over 6 Feet: Any fence taller than 6 feet will require a building permit.
- Fences in ECAs: If your property is near wetlands, steep slopes, or other ECAs, you may need additional reviews and approvals, even for fences under 6 feet.
- Property Lines and Public Right-of-Way: Fences cannot encroach on public sidewalks or streets. Ensuring accurate property lines is essential to avoid disputes or city violations.
Steps to Obtain a Fence Permit
- Check Zoning and Codes: Determine whether your property is in a zoning district or near ECAs that could impact your permit requirements.
- Prepare Detailed Plans: Submit site plans, fence design, and other required documentation to the Seattle Department of Construction and Inspections (SDCI).
- Submit the Application: Complete the online permit application through SDCI’s portal, paying attention to required fees.
- Wait for Review and Approval: The review process can take several weeks, especially if additional environmental or zoning reviews are needed.
- Inspection: After your fence is built, the city may require an inspection to ensure compliance with approved plans.
