Arkansas Residential Code: Stairs & Guards

Arkansas builds to the Arkansas Residential Code, based on the 2021 IRC, adopted statewide as part of the Arkansas Fire Prevention Code Vol. III, effective 1 January 2023.

No Arkansas-specific stair or guard amendment has surfaced, so for a house stair the figures follow the IRC baseline — 7¾ in max riser, 10 in min tread, 6 ft 8 in headroom, 36 in min width, 34–38 in handrails, 36 in guards, the 30 in guard trigger and the 4 in sphere. See the US stair & guard rules for the shared figures. No source URL was on file for this code at time of writing, so confirm the current edition in force where you build.
