In unincorporated urban residential Clackamas County, fences and sight-obscuring plantings may reach 6 feet at or behind the front building line, but only 4 feet forward of it (toward the street). Inside cities, the city's code applies.
Fence height in the unincorporated county is a Zoning & Development Ordinance (ZDO) standard, not a countywide flat number. In the village-lot urban residential districts the ZDO caps fences/sight-obscuring plantings at 6 feet behind the dwelling's building line and 4 feet in the area forward of it. Corner-vision rules further limit anything sight-obscuring within 20 feet of an intersection to 30 inches. Rural (RA-2, EFU) districts rely on setback and corner-vision limits rather than a stated height cap. Oregon cities (Oregon City, Lake Oswego, Milwaukie, Happy Valley) set their own fence heights.
A fence exceeding the standard is a ZDO violation enforced by Code Enforcement (503-742-4452); the county issues a notice to correct and may pursue civil penalties until the fence is brought into compliance.
