Can you carry a gun in a bank in Michigan?

Per MCL 750.234d, it is a 90 day misdemeanor to possess a firearm on premises of a bank or depository financial institution unless you have a valid concealed pistol license (CPL) from Michigan or another state or you have permission of the owner (or agent) of the bank.  If you have a CPL, you may legally possess a firearm in a bank provided there are no prohibitions put in place by the bank such as a policy prohibiting firearms on the bank’s property.
