Thanks Jim, I saw that but it pertains to Exit Access Stairways.  And the definition of an EAS per Chapter 2 is; An interior stairway that is NOT a required interior exit stairway.  The stair I am dealing with is a needed exit from a 2nd floor restaurant to a lobby below

 

 

Stu_SLO: It's not saying it cannot be a part of the means of egress system, it's saying that if the stairway is required to be an interior "exit" stairway, then it cannot be an exit access stairway.

 

The 2015 IBC changes this definition to read much clearer: "A stairway within the exit access portion of the means of egress system."

Stu_SLO:  It can be a part of the means of egress--it is part of the exist access (hence the name, "exit access" stairway).  The travel distance must include travel down the stairs measured parallel to the nosing of the stairs to a point where an "exit" is reached.

See Exception 1 to CBC Section 1009.3.  The exit access stairway is not required to be enclosed if connecting only two stories.  It is not required to be an interior exit stairway per Section 1022 if the travel distance works out.

 

If the travel distance from the upper floor to an exit on the first floor exceeds the allowable, then the stair may have to be enclosed to per Section 1022 for interior exit stairways to shortened the travel distance.  There may be other options.
