Leelanau County ( ) is a
county located in the
U.S. state of
Michigan. As of the
2010 census, the population was 21,708. The
county seat was until recently the unincorporated community of
Leland. On August 3, 2004, county voters approved a proposal to move the county seat to
Suttons Bay Township, closer to the county's geographic center. In 2008, the county offices completed their move to a new government center built on 45 acres (180,000 m²) of county-owned land, one mile east of the unincorporated village of
Lake Leelanau, where a new county law enforcement center was completed.
