hi,
first, i would speak to the inspector. then quote the code.

i think building construction dictates wiring methods..

take for instance a three story dormitory..this may be considered a place of assembly..it is built out of wood and wired with romex...i would be shocked if your inspector would require this building to be wired with a/c cable? even motels get romex..

i would use romex if the ahj will go along with it..if not a/c cable is not too bad but it is more expensive, time consuming and whole lot dirtier..

good luck

-regards
