I know of only one commercial building here that was done in Romex.. Only thing is its a metal clad, wood framed building... because its "combustable" they allowed romex, and the only point at which it is visable is where it emerges from the wall and enters the panel... anything that is exposed or would be such as if there was going to be a drop ceiling in the original plans somewhere, the drops to the lights would have been in BX cable...
