Most of the island is park

Mackinac Island State Park covers about 1,800 acres, roughly 80% of the island. It began in 1875 as the country's second national park and became Michigan's first state park in 1895. In the 1880s choice park parcels were leased to resorters to build summer cottages, and the revenue paid for trails and roads. Hubbard's Annex is different: Gurdon Hubbard platted his own land there in 1882.

About 80% of the island is state park. Cars have been off city streets since 1898.

Above the FHA line, below the conforming line

The $733,300 ACS median for 2020 to 2024 is well over Mackinac County's 2026 FHA one unit limit of $541,287 and under the 2026 conforming limit of $832,750, per Homebuyer.com. The ACS counts 827 housing units but only 176 households living in them, a sign of how many homes are summer places. Named areas run from the cottages of the East Bluff and West Bluff to Harrisonville, Trillium Heights and Mission Point, where the Mission House went up in 1825.

Common questions

Are all Mackinac Island cottages on owned land?

No. Starting in the 1880s, parcels inside the park were leased to resorters who built summer cottages on them. Other areas are private land. Hubbard's Annex, for one, began in 1882 when Gurdon Hubbard divided his land for a summer cottage community. Title work should confirm whether a cottage sits on owned land or a park lease.

How do year round residents get on and off the island in winter?

About 500 people live on the island all year, per the Mackinac Island Tourism Bureau. Ferries usually run until about mid January, when the water freezes, and residents fly after that. Mackinac Island Airport has a 3,500 foot paved runway. The public school has about 70 students from kindergarten through high school.
