A bit of a necro on this thread but a similar question.
If I have an existing "partial" building (WI - IEBC 2015 code) with 2 stairs, one "exit stair" to the north and one "exit access stair" to the south. The partial building is connected to a larger building with it's own stair systems/exits, separated by a fire wall. I want to close off the additional openings into the "larger" building on all but the first floor, can I do that for the small portion? (Assume the larger building complies on it's own).
At the first floor, the exit access stair would have travel access to the rest of the "larger building" for egress, so all the floors in the "partial" building have access to (2) exits (complying with IBC 1006.3).
The IEBC would require the exiting stairs to be enclosed (they are) and rated (they are not) as I'm a type III alteration. As far as I can tell, although they must be enclosed, there doesn't seem to be a requirement for both stairs to be "Interior Exit Stairways".
The IBC requires continuous protection for the exit components, but because the south stairway is "exit access" I don't think the protection requirement applies. Is this correct? am I missing something?
