Assuming you don't have excessive, unprotected SE in the building I think it is OK.

230.40 Number of Service-Entrance Conductor Sets.
Exception No. 1: A building with one or more than one occupancy shall be permitted to have one set of service-entrance conductors for each service of different characteristics, as defined in 230.2(D), run to each occupancy or group of occupancies.

There is only one service but it can still "be run to each occupancy".
