Frat House Classification

Bubbles

Question:

10,000 sq ft Frat House classified as commercial (1 meter)
Adding New Service 24 person occupancy

adding 40 circuits Refer/Micro and GFI's

All walls have been left. Not easy to run new circuits.

Leaving 60 other circuits in existing sub panels using conduit as ground..

I have field inspection tues but would love a heads up as what will he say on all bedroom (20) circuits which are currently NOT on arc faults which we were not going to touch or alter. They are on old slim GE breakers which I've never seen in an arc fault version. Can they overrule and force us to put in Arc Fault in EXISTING circuits which in turn would make us have to change 6 subpanels as well. I would prefer to change everything but owner is cheap and wants only to do basic code compliance.

Place of Assembly Rules??

Not sure yet if building dept. will make us interconnect smoke detectors as well. Anyone have any luck with wireless interconnected smoke detector systems.

Thanks
