Full Breakdown
Portland splits dangerous fence materials into two rules. Barbed wire is allowed on any fence under City Code § 24.60.020, but only if strung at least 6 inches above the top of a fence that is already at least 4 feet tall; anything less makes it unlawful to construct or maintain. Electric fencing is tighter: § 26.03.110 prohibits battery-charged fences on any property zoned or used for residential use, and hardwired electrified fencing is confined to industrial-use locations, requiring a laboratory-listed product, an electrical permit and inspection, and "DANGER - Electrified Fence" warning signs posted at intervals no greater than 50 feet.
Violations & Fines
Building or maintaining a noncompliant barbed-wire or electric fence is unlawful under Titles 24 and 26; the City Administrator can issue a stop-work order and pursue Chapter 3.30 remedies, and unpermitted electrical fence work risks power disconnection.
