This is not an NEC requirement. Check with your local AHJ.

There is no requirement that a bathroom without a shower or tub even have an exhaust fan. Wire it as you see fit. "Commercial" bath fans are typically almost always switched with the light or on a timer for occupied hours, however. It's normally only in a dwelling that you'd find the bath fan separately switched.

Local codes may apply. Either building or mechanical.

Local codes.. you know... codes that are local. Codes that only apply in that area/town/city/state/ locality. Not everyone adopts the NEC, and even those that do can adopt amendments.
Or are you asking about mechanical and building codes?

I'm curious if there is any code out there that wouldn't let him switch it like he wants to.

I've searched the IRC, IBC, and IMC for about an hour now. The only bath fan exhause requirements I can find are for hotels/motels and private dwellings. Other than that, there doesn't seem to be any exhaust fan reuirements at all. granted, you're dumb if you don't provide exhaust. There just doesn't seem to be any code requirment with regard to how you switch it.
