Allen County sets fence placement by setback and corner-visibility rules rather than a shared-cost mandate. On a corner lot without a platted build line, a fence must meet a 5-foot side-yard setback, and no fence may block corner sight lines.
Allen County's Zoning Ordinance governs where a fence sits relative to lot lines. On a corner lot with no platted building line, a fence (other than an ornamental fence or retaining wall up to 3 feet) must meet a 5-foot setback; an ornamental fence or 3-foot retaining wall has no setback. On a corner lot, no fence, hedge, retaining wall, or structure may impede vision between 3 and 8 feet in height within the corner visibility area (40 feet from the intersection). The county does not mandate cost-sharing between neighbors; boundary and shared-fence cost disputes are a private civil matter under Indiana law.
Objects impeding corner sight lines or fences in required setbacks are zoning violations enforced by the DPS Zoning Administrator (correction or removal).
