Looking in my Michigan Firearms Law booklet from this past May CCW renewal, private dwellings are not listed in Michigan's concealed carry
Pistol-Free Zones.
Personally, I think walking into a private home while carrying is a "Don't ask, Don't tell" situation. If I carry while in my own home......I'd hope my friends would consider my carrying as comforting.
But, specifically prohibited in Michigan are:
College dorms and classrooms
Private or public child daycare centers
Six other sites like a sport stadium, school, tavern where primary source of income is alcohol, places of worship, private facilities with seating capacity of more than 2,500 people.
(Nice list of places for bad guys to cause trouble without fear of instant reprisal, eh?)
No, I'm not gonna call the local police department and ask, either.
