Mich. Admin. Code R. 259.293 - Nonconforming structures and trees
Rule 293. These rules do not require removal, lowering, change, or alteration of a structure, vegetation, or other object not conforming to these rules as of their effective date. However, the owner of a nonconforming object shall without expense provide or permit installation, operation, and maintenance of markers and lights deemed necessary by the commission to indicate the presence of airport hazards. Where an airport hazard area exists in connection with a public use airport, the commission shall define and determine the airport hazard area and certify such determination to the political subdivision where the airport is located, and to the airport owner or operator.
