Code states egress from a room or space shall not pass through adjoining or intervening rooms or areas, except where such adjoining rooms or areas and the area served are accessory to one or the other, are not a Group H occupancy and provide a discernible path of egress travel to an exit.
But, what if the exit door connected to the fire-rated stairway is not a necessary means of public egress and only for roof access? The space is a mezzanine with mixed occupancies, but under 49 occupancy load. So, correct me if I'm wrong I only need one means of egress from the space. The client wants a door accessing the fire-rated stairway for roof access, but not as a means of egress. Do we have to have a corridor to that door through the spaces or can we access without?
