Nothing even close to that around here. Romex is allowed just about everywhere. Attached garages must be sheetrocked on attached walls and ceilings of course, but outside walls can be open framing with regular NEC considerations for wiring practices. Detached garages are fair game for anything as they are treated like sheds. I'm guessing that must be a local AHJ thing.
I do have some old BX! Actually, it is 14/2 MC. I have no idea how I ended up with that stuff. I sure do remember wiring plenty of new houses with BX in Northern NJ as recently as the early 1980's.
