The Michigan Governor's Mansion and summer residence are located in the U.S. state of Michigan.
Both residences are owned by the state of Michigan and are maintained with private donations. The Michigan Constitution specifies that there is to be a Governor's residence at the seat of government, and that the seat of Government shall be at Lansing.
The governor's mansion in Lansing was built in 1957 for Howard and Letha Sober, who donated it to the state in 1969. The furnishings were provided by the State of Michigan. American architect Wallace Frost, who was known for traditional architecture, designed the ranch-style residence with its stone exterior in a contemporary style. The contemporary architecture was a change from his usual style. A garden room was added in the mid-1970s. The gated mansion sits on approximately four acres of secured area in the Moores River Drive estates of Lansing near the scenic Grand River. Governors who have lived in the mansion during their office tenure include William Milliken, James Blanchard, John Engler, and Jennifer Granholm. The mansion in Lansing was renovated during the early 2000s and contains 10,300 sq ft (960 m2), five bedrooms, and four baths. The current governor, Rick Snyder, has elected to remain at his Ann Arbor residence.
The Michigan Governor's Summer Residence on Mackinac Island is a three-story structure located on a bluff overlooking the Straits of Mackinac. It was originally built as a private residence for Chicago attorney Lawrence Andrew Young. In 1944, the Mackinac Island State Park Commission purchased the home for its original cost of $15,000. Since then, Michigan's governors have used this home to host important events with national and state leaders. The house was named to the National Register of Historical Places in 1997.
