The village council may designate an official landmark or historic district. Upon adoption of an ordinance approving the designation of a landmark or historic district, the village council shall direct that notice be sent to the building commissioner and to the owners of record advising them of such designation and informing them that any structure, building, site or area designated as a landmark or located within the boundaries of a historic district shall thereafter be subject to the requirements of this title. The village council shall also direct that the ordinance approving such designation be recorded in the offices of the Cook County recorder of deeds. Said designation shall not be approved without the consent of the owner of record for landmark designation, or without the consent of more than fifty percent (50%) of the owners of the lots in a historic district, as set forth in this title.
