The sheet carries the fixture clearances as drawn geometry on their
own layer, with the dimension strings and room notes outside the
walls.

IBC 2021 Chapter 10 stairways (unverified)
— The commercial stair is a different animal: IBC stairways are 44 in wide with a 7 in maximum riser and an 11 in minimum tread, so the same storey takes more risers and a longer run. A stair drawn to residential numbers cannot be reused in a commercial fit-out.

read as a pointer to look the section up rather than as a
quotation of it.

A single room on its own sheet is not a whole building, so the
checks that grade a floor plate — exit counts, circulation
share, fixture counts against an occupant load — have no
subject here. They are listed rather than counted as passes.
