Gentlemen:
Here in NJ we use a UNiform Construction Code (State). It adopts National Codes (NEC, BOCA, NFPA, Etc.) with amendments. Licensed inspectors all should have a copy, and updates are issued monthly, as it is in looseleaf form. It covers everything, including a remodel/renovation section.
As to the placement of devices, the corresponding codes have to be satisfied. The various AHJ's (Elec., Building, Plumbing, Fire, Elevator, Mechanical, etc) are responsible for each discipline, as all have to do mandatory plan review. The ultimate goal is to have everyone "on the same page.
The electrical AHJ checks device/equipment connections, wiring, etc., to the NEC. The "other" AHJ's are "supposed" to take care of the placement of devices/equipment that are not within the scope of the NEC.
