All Tenant lights powered by the house panel

[Johnny B.]

I have a project where it was bid for lighting and power to be separated out. There are 3 tenant spaces and then the house space such as the stairwells and the elevator, corridors etc. The lighting designer did not separate out the lighting circuits per tenant space so I believe the intent is to have it all powered by the house. Does this violate NEC 240.24 with accessibility for the tenant to shut off their own lighting? Or does it work if all the lighting has override switches to their controls I am thinking it would count as supplementary protection from NEC 240.10. Bad design in my opinion to make the owner of the building pay for all the tenants lighting but I want to check also does this violate any code? I am also checking this because I have to show what circuits power the lights.

I would make sure it's not an error first. I am trying to figure why anyone would want that done.

Is the intent to have lights despite the tenants, or to not have lights despite the tenants?

I am not sure what the intent is. But the lighting designer just told me it has been confirmed with the architect its what they want.

My guess is it would make changing tenant space size easier. Power cost is built into the square foot lease rate.
