    Read exceptions in chapter 10, section 1005 for stairs, doors and corridors.
    0.3 for stairs changes to 0.2 if building is equipped with automatic sprinkler system.
    0.2 for doors/ corridors changes to .15 for the same reason.

    I suggest reading the entire ch 10 of IBC.  Be sure to read the 'vanilla' version, and not a state modified one.

    The various widths depend on factors like sprinklered or not.  Low occupancy (under 50) can be 36" width even.   There are lots of exceptions.  The standard minimum width with sprinklers is 44" CLEAR.

    Hope this helps & keep studying!
