Tomselectric:
Here in NJ, IF the switches are on the prints submitted for plan review, and issuing of an electrical permit...they shall be installed. The only acceptable way NOT to install them would be a letter (signed and sealed) from the Architect/Engineer of Record stating that it is an approved change.
As Iwire stated...the NEC does not require comm switches, but an energy code, or local (state) regulations may make it mandatory.
I suggest you check with the area AHJ before you get in to deep.
