Common Path of egress in space with single exit

[RayP]

please follow link below for a floor plan of the space in question. Is there any reason why the red arrow couldn't be used as the common path of egress for a space with a single exit? Based on my review of the "Building codes illustrated" by ching and the definition of "common path of egress", "exit access doorway" and CBC table 1006.2.1, the red arrow illustrated should match the definitions. This is a B-occupancy fully sprinklered where the occupants are less than 49.

Otherwise, does anyone have any suggestions on how to maintain this as a single exit? the plan checker is pushing 2 exits.

If there is only one path out of an area, then that is the common path. Since the suite has only one door that leads to an exit, then the common path is all the way to the main exit door from the lobby. If that distance is greater than 100 feet (which it is per your measurement of 155 feet), then you will need a second exit from the suite.

^^^^^That is what I was thinking but didn't zoom in to see the measurements yet....

Why in the world would you have a toilet room access through the break room? That would be against the plumbing code in a commercial food prep area and is definitely not a good design in this example.

Where considering the provisions of a CPET, you have to think of where the occupants are provided with two separate paths to exits. Where you only have one exit, there may be multiple routes to get there, but it still ends up converging back into a single pathway. For that reason, it would remain a CPET.

The simple answer is provide one more exit doorway. That way, if two people left the breakroom, they could end up going out two separate exits; thus, the CPET would end where those two persons could take a separate route.

not related to CPET, I would take a second look at the number & location of the toilets in your design. This appears to be some sort of medical office which in my experience is subject to FGI Guidelines (Facility Guidelines Institute) which typically calls for more toilet facilities than required by the plumbing code.
