I am working on a multilevel office building project with several stairwells. Can I put all of my stairwell lighting as unswitched? The first floor of all stairwells where I work has a switch on the first floor.
 
I believe most Energy Codes require lights that have bi-level occupancy settings so that they are at 50% when there are no people in the stairwell.
 
I think this answers it

210.70(A)2) Additional Locations. Additional lighting outlets shall
be installed in accordance with (A)(2)(a), (A)(2)(b), and
(A)(2)(c).
(a) At least one wall switch?controlled lighting outlet
shall be installed in hallways, stairways, attached garages,
and detached garages with electric power.

All just my opinion....
It'd be in your Building Codes!
I'm almost going to say no, really the only safe thing is to have infra-red motion
instead of switch's, and you'd probably have to have a lot of eyeballs. Lights needs to be on for public emergency egress purposes, yet it'd be an AHJ call if you want to switch them. A private entrance stairwell is different than a public use one.

That's why I love this place...:ashamed1:
