Michigan Structure Height Limits (2026)

Key Facts

Permit Trigger Height: Over 200 feet AGL
Airport Approach: Permit required
Permitting Agency: MDOT Office of Aeronautics
Governing Statute: MCL 259.481 et seq.

Full Breakdown

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.

Violations & Penalties

Building without a Tall Structure permit may result in MDOT enforcement orders, mandatory removal at owner expense, and civil penalties under MCL 259.491.

Frequently Asked Questions

Does Michigan preempt all local height limits?

No. Local zoning generally controls building heights, but the Tall Structure Act imposes a statewide ceiling near airports and for very tall structures that municipalities cannot waive.

Are wind turbines and cell towers covered by Michigan's Tall Structure Act?

Yes. Wind turbines, communication towers, and any structure exceeding 200 feet above ground or penetrating airport approach surfaces require a Tall Structure permit from MDOT Aeronautics.

Does FAA approval replace Michigan's permit requirement?

No. Federal FAA review and the Michigan Tall Structure permit are independent requirements. Owners must obtain both before construction begins.
