Thanks Steve. Yeah, not talking about storage closet under the stairs but
under the angled stair risers that would be open and part of the room. 13R
does a fair job of addressing this. 13D does not. My first thought would be
to address this as an obstruction but 13R acknowledges in the appendix
If it’s a closet, I would protect it. If it’s an open stairwell in a
sprinklered compartment, I would not. In a 13D design, I would not concern
myself with whether the stair is surfaced with non-combustible sheathing or
not, but that’s MY opinion only.
