Feeder from another tenant space

[hhsting]

I have two tenant spaces A and B. Tenant space A has electric room in which all the tenant A panelboards lights and power reside.
If I use one of the panelboards in tenant A space and I place 100A feeder breaker which would feed panelboard C with main breaker in tenant space B then would that make it non code compliant against any NEC 2014 sections? The electrical room in Tenant A space would be accessible to management, tenant A but not tenant B.

Done all the time in commercial buildings. Labeling would be critical. Put sub-metering in if necessary.

Who is paying the electric bill, the landlord or tenant? I don't think that there is a problem with accessibility but tenant a surly does not want to pay tenant b's electric bill.
