Most townships in Michigan require some kind of setback from property lines for accessory structures. Common setbacks range from 3 to 10 feet, but your specific township may be different. Some areas also have different setbacks for side yards versus rear yards, or different rules if you're on a corner lot.
Before you pick your spot, call your local zoning office and ask about accessory structure setbacks. While you're at it, ask about any easements on your property. Utility easements can restrict placement even if your property line setback is clear.
