Full Breakdown
Two layers of Chicago law govern fence height. The Municipal Code (Building Code) Section 13-96-140 sets construction-based maximums: a combustible screen fence may not exceed 8 feet; a combustible solid fence may not exceed 6 feet (and may reach 8 feet only where the distance to a public way exceeds the fence height, or where the fence is laterally braced or supported by noncombustible posts in masonry/concrete foundations); a noncombustible screen fence may not exceed 10 feet (15 feet enclosing an open-air assembly or institutional/business/industrial/storage yard); and a noncombustible solid fence may not exceed 8 feet (12 feet for those same enclosed yards).
A 'screen fence' is at least 50% open apertures; a 'solid fence' is less than 50% open (Sec. 13-96-130). 5 feet in the front setback (the commonly cited '54-inch' rule) but up to 6 feet in side and rear setbacks. Fence heights of 6 feet or more that are solid are therefore confined to side and rear yards.
Violations & Fines
Erecting a fence above the applicable Building Code or Zoning height is a Municipal Code violation enforceable by the Department of Buildings. Section 13-32-200 makes it unlawful to erect a fence more than five feet high without a permit; unpermitted or over-height fences can draw a stop-work order, administrative hearing citations, and an order to lower or remove the fence at the owner's expense.
