How do you do an inspection and verify the circuits are working properly (which is required by code) without there being a fixture of some sort installed? If just the bulb is burned out, how do you know? I don't think the code requires the lights to be there, all at the same time I don't think you can say the system works properly and pass the inspection without the fixtures being installed.
Is an outlet just the box, or the box with the wires installed? If it's just a box, then the contractor doesn't need to have any wires pulled. (We use pipe in Chicago)
If you want to get real picky, could someone show me an outlet controlled by a switch? The switch controls, ultimately, the device or fixture or utilization equipment attached to the circuit, not the outlet itself.
How about 110-3(8), (99 NEC Sorry I don't have my 2002 book with me) to require them to install some kind of fixture.
