Quick answer
In unincorporated Snohomish County a fence 8 feet or less in height does not require a building permit, as long as it has no masonry or concrete elements above 6 feet (wire strands on top of an 8-foot fence are not counted toward the height). Fences taller than 8 feet, or with masonry/concrete construction above 6 feet, require a building permit applied for through the PDS Permit Portal. Fences must still meet property-line setback rules.
Typical threshold: fences 8 feet or less in height exempt, provided they have no masonry or concrete elements above 6 feet (wire strands atop an 8-foot fence are excluded from the height measurement); taller fences, or fences with masonry/concrete above 6 feet, require a permit.

How to apply in Snohomish County
In Snohomish County, most residential fences fall under the model code's 7-foot building-permit exemption, so the real approval step is a lightweight zoning or land-use permit built around a simple site plan showing the fence's location, height, and material, checked against setbacks and any corner-lot sight-triangle rule. A fence that will serve as a required swimming-pool barrier is the exception, since barrier fences carry life-safety requirements of their own.
What most fence permit applications include:
- For Snohomish County, a fence 7 feet or under is exempt from the model code's building permit, the same threshold the IRC uses for other small projects (IRC 2021 R105.2).
- That exemption only removes the building-code permit. It does not authorize skipping a jurisdiction's own zoning approval, which is why an exempt fence can still need its own land-use or zoning permit rather than a building permit (IRC 2021 R105.2).
- Whatever your jurisdiction calls that approval, the application centers on a basic site plan: a drawing of the property showing the fence's location, height, and material, and how it relates to the property lines (common local zoning practice).
- For Snohomish County, the same plan is checked against required setbacks and, on corner lots or near intersections, a sight-triangle rule that caps fence height so it does not block sightlines for drivers (common local zoning practice).
- For Snohomish County, a fence that will serve as a required swimming-pool barrier is handled as life-safety work rather than the light zoning process, and at least one state's adopted residential code requires a building permit for barrier fences regardless of the general fence exemption (Oregon Residential Specialty Code 2021, R101.2.2).

Inspections and closing out your permit
In Snohomish County, inspection follows the permit: a fence that never needed one gets no inspection at all under the model code, and a permitted fence typically gets a single final check rather than the staged inspections used for a house. The exception is a fence serving as a swimming-pool barrier, which gets its own dedicated barrier inspection covering height, gaps, and gate hardware.
- In Snohomish County: inspection duty attaches only to work for which a permit is required, so a fence that qualified for the permit exemption carries no inspection obligation under the model code (IRC 2021 R109.1).
- In Snohomish County: where a fence permit was issued, the process skips the staged foundation, frame, and rough-in inspections used for buildings and goes straight to one final inspection once the fence is finished (IRC 2021 R109.1.6).
- In Snohomish County: that single check is typically a zoning compliance inspection rather than a structural review, confirming the fence matches the approved height and site plan (common local practice).
- A fence built as a swimming-pool barrier breaks that light-touch pattern in Snohomish County: it is separately inspected for barrier compliance, commonly required before the pool itself can be signed off (ISPSC 305; local pool-barrier inspection programs).
- In Snohomish County: that barrier inspection checks dimensional rules from the swimming pool and spa code rather than ordinary fence rules, including the minimum 48 inch barrier height and limits on openings and gaps a young child could pass through (ISPSC 305).
- Gate hardware is inspected too in Snohomish County: a self-closing, self-latching gate is part of the barrier requirement, since an unlatched gate defeats the fence's purpose as a barrier (ISPSC 305).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Snohomish County permit portal or by phone at 425-388-3311.

- Where do you apply for a fence permit in Snohomish County?
- You can apply through the Snohomish County permit portal or contact the Snohomish County Planning and Development Services directly. The links are listed on this page.
- Can a homeowner pull a fence permit themselves in Snohomish County?
- Under Washington law (RCW 18.27.090(11), (12); RCW 19.28.261(1); RCW 18.106.150(1)): Washington lets homeowners do their own construction work, including the licensed trades, on property they own. RCW 18.27.090(12) exempts any person working on his or her own property from contractor registration, but the exemption does not apply if you do contractor type work for the purpose of selling, demolishing, or leasing the property, and the separate owner exemption in RCW 18.27.090(11) is lost if you sell or lease improved property owned less than 12 months. For electrical work, RCW 19.28.261 lets you wire your own residence, farm, or place of business without an electrician license, unless the work is on construction of a new building intended for rent, sale, or lease, or on property offered for sale within 12 months after you obtained it. RCW 18.106.150(1) gives the same kind of exemption for plumbing work at your own residence, farm, or place of business. These exemptions waive the license, not the permit: an owner doing electrical work still buys an L&I electrical work permit and passes inspection (WAC 296-46B-901), and building and plumbing permits still come from your local building department. Confirm how Snohomish County applies this before you apply.
