Before the law considered a wheelhouse type house was "portable" thus didnt need a license if it wasnt left unoccupied on the ice. Wheelhouses are now not considered portable and needs a shelter license. If you have a flip type, suitcase, hub etc that is folded you still dont need a shelter license as before.
But you can not be more than 200 feet away from it
