Pasco, WA Fence Regulations: Neighbor Fence Rules (2026)

Pasco's municipal code regulates fence height, materials and placement through PMC 25.180.050, but it does not impose a general requirement that adjoining residential neighbors split the cost of a shared boundary fence. Washington's statewide partition-fence law, Chapter 16.60 RCW, does address cost reimbursement: under RCW 16.60.020, when one owner has built a fence on the boundary line and an adjoining owner later encloses their own land using that fence, the adjoining owner pays half the value of the portion serving as a partition fence. However, Chapter 16.60 sits within Title 16 RCW, 'Animals and Livestock,' and its 'lawful fence' definition describes barbed-wire livestock fencing. As a practical matter, these provisions are generally applied to farm and livestock enclosures rather than ordinary residential yards. For typical residential neighbors in Pasco, fence placement, ownership and cost are largely private matters: the fence must sit on the correct side of the surveyed property line (or be jointly agreed), respect setbacks and easements, and meet PMC 25.180.050. A licensed survey is the reliable way to avoid encroachment disputes. For boundary, cost or removal disagreements, consult an attorney; the city does not adjudicate private fence-line disputes.
