Remodeling of existing 22,000 sq ft (650 person max. capacity) metal building with wood framed partitions, sheet rock, and suspended ceilings, being used for a religous assembly. My building inspector is telling me that I cannot use romex for the interior wood stud walls. I understand that after I leave the wood framing I am required to use MC Cable, conduit, etc. but why can't I use romex up to that point? Any help with this would be appreciated.
