Summary
Marion County's zoning code exempts fences from the minimum yard-setback requirements, so a conforming fence needs no land-use permit. Under Oregon's building code a structural building permit is required only for fences over 7 feet tall.
Minimum Setbacks: ... the following setback requirements shall be implemented for all new structures other than farm-exempt buildings, signs and fences.
Full Breakdown
Marion County treats fences as exempt structures: the EFU and Acreage Residential minimum-setback rules (MCC 17.136.100(B), 17.128.060(B)) apply to new structures 'other than farm-exempt buildings, signs and fences,' meaning a fence may sit on the property line without a setback approval. No separate county fence permit is issued for a code-compliant fence. Oregon's Structural Specialty Code requires a building permit only when a fence exceeds 7 feet in height (or for masonry/retaining walls over 4 feet). Inside Salem, most residential fences also need no permit, but must still meet height and vision-clearance rules. Utility easements and sight-distance limits still apply.
Violations & Fines
Building without a required permit for an over-7-foot fence, or violating height/vision rules, can trigger a stop-work order, correction notice, and removal.
