Also, often there is a step up to the laundry equipment (often there isn't). Often it has been moved there long after a CO is issued. I have always been surprised that the laundry is even allowed in the garage.

My dryer installation manual says: "THE DRYER AREA IS TO BE KEPT FREE AND CLEAR FROM COMBUSTIBLE MATERIALS, GASOLINE AND OTHER FLAMMABLE VAPORS AND LIQUIDS."
Kind or rules out a garage.
