Does egress switching apply to non dwelling units?

[electricblue]

I have a non dwelling unit commercial bathroom. It has 2 entry exit doors the architect had the exterior lighting controlled by time clock and is now changing it to one switch by one door I have a feeling this is not the code am I right. I just want to confirm that I'm right before I tell them I told them it needs to be three way switching one by each door

Barring any local codes, the architect's one switch is not a violation. And, there is nothing in the NEC that requires 3-way switches.

The NEC does not even require a switch at one entrance. You could even put the switch across the building somewhere.
