Fence Installation Permits in Portland
Local Rule
City of Portland Bureau of Development Services
Portland does not require a building permit for a fence of wood or similar materials up to 7 feet high, or masonry/concrete fences up to 4 feet, or typical field fencing up to 8 feet, per the city's own Brochure 3 and BDS fence permit page; a fence enclosing a swimming pool always needs a permit regardless of height. Fence height is measured from the ground where posts enter the ground to the top of the fence, including lattice or any added material. Even a permit-exempt fence may still need a zoning permit, particularly for front-yard fences (front-yard fences are limited to 3.5 feet, and applicants should contact Transportation/Engineering to confirm the fence isn't within the public right-of-way). Fences taller than 8 feet must meet additional structural requirements and typically need design by an Oregon-licensed engineer. Properties in an overlay zone or plan district may have alternative standards requiring a zoning permit.

How This Compares to Multnomah County
Portland's own rule is shown above (No permit under 7 sqft). Here is the separate rule that applies at the county level, for context:
Municipal — administered individually, with Portland coverin
Oregon is unusual in that the state itself, not individual cities, sets the fence-exemption floor: the ORSC explicitly exempts wood, wire mesh, and chain-link fences under 7 feet, and municipalities legally cannot require a building permit below that height (masonry and concrete fences are the exception, cities may regulate those independently). Portland, the largest city in Multnomah County, administers building permits directly for specified unincorporated Multnomah County areas under a county service arrangement, and requires an Oregon-licensed engineer's design for any fence over 8 feet.
