All districts
In all districts, fences may contain no barbed wire and no electrical current or charge of electricity (§ 4.10 FN-01). Playground fences may reach 7 feet and may be at most 25 percent sight-obscuring. Fences must be maintained.
In R1 through R8 and TZ1 (§ 4.11 FN-02):
- Up to 6 feet in required side or rear open space.
- Up to 3 feet in the front open space, with two exceptions: behind the front of the principal building, and immediately adjacent to the rear lot line of a corner lot, where 6 feet is allowed.
At corners, nothing may be maintained at a height that obscures drivers' vision (§ 4.89 VC-01). The ordinance states this qualitatively; it sets no numeric sight triangle.
