Full Breakdown
Village Code § 6-11-3 caps residential fence height at six feet between buildings or in the rear yard, measured from established grade to the fence's topmost point. Fences may not extend past the front yard building line set by the zoning ordinance, nor past the side street yard line on a corner lot, and none may be erected in a public right of way. Commercial, office and manufacturing districts share the same six-foot cap but add a 90 percent unobstructed-view requirement between the building line and property line. A permit ($30 fee) is required before any fence over 2 feet is erected, per § 6-11-2.
Violations & Fines
Fines run $10 to $750 per violation under § 6-11-7, with each day a noncompliant fence stays up counting as a separate offense. Fences built without the required permit or past the allowed line are also subject to correction orders from the office of quality control.
