While far and away most, (not all) homes in the US have 220V to service HVAC, dryers, ovens and whatnot, very few have extra 220V circuits and very few over twenty years old have 220V in the garage or carport, unless the dryer or HVAC in an attached garage.
Unless upgraded by the homeowner, virtually all detached garages in tract homes have no panel and only two 15-amp circuits, one for lights and one for an outlet.
