This guide notes some provisions in the International Building Code (IBC) and the ICC A117.1 Standard for Accessible and Usable Buildings and Facilities that are not found in the ADA Standards. For example, the A117.1 standard, which provides technical provisions and is referenced by the IBC, requires a vertical grab bar at showers and bathtubs. It also requires a folding seat in all roll-in showers. Not all differences between the ADA Standards and editions of the IBC and A117.1 standard are noted in this guide.
