The company I work for owns several apartment complexes in addition to other investment properties.

I was just asked to oversee a renovation project at one of the complexes that just had a State DCA inspection.

I'm going through the pages and pages of paperwork and one of the violations that shows up in every single apartment is "insulate bathroom/toilet room electrical switch, wall plate and screws"

The property manager tells me that the inspector said that all switch plates in a bath or kitchen had to be plastic. I remember being hit with the same violation many years ago when I was chief engineer for a couple of hotels.

Is there an NEC reference for this? And I'm not sure how to provide insulated screws. I vaguely remember seeing plastic cover plate screws before, possibly packed with a GFCI but my memory on this is hazy. Any information appreciated.
