The Village of Grass Lake is located in Eastern Jackson County between Ann Arbor and Jackson. The Village lies 2.6 miles south of I-94, which leads to points east and west and provides access to routes running north and south. The Village's main street, Michigan Avenue, which was formerly Old US 12, became simply an east/west route through Jackson County and the Village when I-94 was opened. it remains a main thoroughfare through the area leading to the City of Chelsea to the east and the City of Jackson to the west. The area maintains its rural character and holds a rich heritage in the late 1800's and early 1900's era structures in the core of downtown, the focal point of which remains the old Michigan Central Railroad Depot at 210 E. Michigan Avenue.
