Portland does NOT require a building permit for fences 7 feet tall or less in residential zones — this is one of the city's most permissive features. PCC 24.10 (adopting the Oregon Residential Specialty Code) and the Bureau of Development Services exempt residential fences up to 7 ft from building-permit review. However, fences must still meet PCC 33.110.255 height limits (3.5 ft front, 8 ft side/rear) and vision-clearance rules under PCC 33.266.220.
Under the Oregon Residential Specialty Code (adopted by reference in PCC Title 24), one-story residential fences 7 feet tall or less are exempt from a building permit. Portland's BDS confirms this exemption applies citywide for residential fence installation, repair, and replacement. Two categories DO require permits: (1) fences over 7 feet in height (which also need a Type II adjustment under PCC 33.805 to exceed the 8-ft zoning cap, plus structural review); (2) any retaining wall over 4 feet in height (measured bottom of footing to top of wall) under ORSC R404. Commercial and industrial fences typically require permits regardless of height. Installing a fence on or near a property line does not require a survey unless there's a boundary dispute, but Oregon law requires you to give neighbors reasonable notice; ORS 96.020 covers shared boundary-fence costs. The permit exemption does not waive zoning compliance — installing a 6-ft fence in the front-yard setback (where the cap is 3.5 ft) is a zoning violation even without a building permit.
Building a fence over 7 ft without a building permit triggers a stop-work order from BDS and double-fee retroactive permitting. Zoning violations (exceeding PCC 33.110.255 height limits) are separate enforcement matters with notice-to-comply and $250-$1,000/day fines. Retaining wall over 4 ft without permit is a building-code violation potentially requiring removal/rebuild.
