Some discussion with the building department revealed that this was a single occupancy so I could not use 230.40 ex 1. I asked what it would take to legally make this two occupancies and they said there were specific fire separation requirements and zoning would likely come into play also.

I think you will find that in most places. Usually a 2 hr separation between occupancies.


I have seen many times where a second service was added to a facility when additions were put on. A 2 hr separation effectively makes them separate buildings per building codes. They may be permitted to have doors between each "building" but they must have 2 hour rating and automatically close during fire alarm conditions. Wiring from one building can not feed into the other either.
