Full Breakdown
St. Louis's Building Code, adopted at Revised Code § 25.01.010 and amended at § 25.01.020, adds Section 430 governing fences citywide. Section 430.1(4) bars any barbed wire fence or fence topped with barbed wire, razor ribbon, or like material for any use group in residential zones, and requires that any barbed wire allowed elsewhere stay at least seven feet above the ground. Section 430.1(8) goes further, banning electrically charged fences outright everywhere in the city, with no zoning exception. The Building Division enforces these rules alongside the same section's fence height limits (48 inches at the front building line, 8 feet on side/rear lines in residential zones).

Violating the fence rules is a Building Code violation enforced by the Building Division, punishable by a fine under § 25.33.040; each day the violation continues is a separate, distinct offense.
