Full Breakdown
Under the Olathe Unified Development Ordinance, fences, walls and hedges in residential districts (and the N district) may reach 6 feet, measured above average grade at the property line. In front yards or corner side yards, beyond the front of the house, the cap drops to 4 feet, the fence must be at least 50% open, and chain-link or other metal/wire fencing is barred outright. Commercial and industrial districts allow up to 8 feet. No fence, wall or hedge may obstruct the intersection sight-distance triangle defined in UDO § 18.30.220, and in residential districts fences must sit entirely outside that triangle. Barbed wire, razor wire and above-ground electric fencing are prohibited in residential (except AG) and commercial districts.
Violations & Fines
