Not including the permitted projection for handrails and stringers, what is the minimum clear width of the stair at dimension X?
Comprehensive and Detailed Explanation From Exact Extract:
For stairs serving 100 occupants, building codes such as IBC require a minimum clear width of 44 inches to accommodate occupant egress.
36 inches is typical minimum for stairs serving smaller occupant loads.
Wider widths like 48 or 60 inches are required for higher occupant loads.
Handrails and projections may reduce nominal width but are not included in minimum clear width measurements.
