Michigan's Aeronautics Code universally restricts structure heights near public-use airports through the Tall Structure Act, applying statewide regardless of local zoning decisions.
The Michigan Aeronautics Code (MCL 259.1 et seq.) and the Tall Structure Act (MCL 259.481 et seq.) require permits from the Michigan Department of Transportation Office of Aeronautics for structures exceeding 200 feet above ground or any structure within an airport approach surface. These airspace protection requirements apply uniformly statewide and override local zoning that would permit greater heights. Local airport zoning ordinances under MCL 259.133 must conform to state and federal airspace standards, and approval requires MDOT and FAA review before construction.
Building without a Tall Structure permit may result in MDOT enforcement orders, mandatory removal at owner expense, and civil penalties under MCL 259.491.
