I am in Michigan near Saginaw. If you show the building inspector calculations for Habitable and Non Habitable space. Non Habitable space will be bathrooms, halls, closets, laundry rooms, basements, finished basements etc. If you can show the Habitable space is lower than 3500 sq.ft. it will be required to be sealed. Michigan House Bill 5819 will reference this if i am not mistaken. This has been in place for number of years. I have not seen a building official in Michigan not follow this. I hatch in the space on a drawing and do the calc's. Hope this helps you out.
