ICC A117.1: Accessible and Usable Buildings and Facilities

The technical accessibility standard the IBC and most state and local commercial codes reference by name rather than writing their own accessibility requirements from scratch. Distinct from TAS and UFAS, which are their own standalone standards issued by other authorities. 12 lessons and a 60-question practice exam, self-paced.

Status

All 12 lessons and the practice exam are live

Every lesson is written and published with a diagram, a glossary, 14 practice questions (20 in Lesson 12) and neural narration. A117.1 is copyrighted by ICC and is not freely reproducible: ICC offers only a free read-only online viewer, with the actual purchasable standard paywalled. Every fact in these lessons was checked against that free viewer for the 2017 edition with Supplement 1, not reproduced from the standard's own text, and this course is GCHS's own independent material rather than official ICC content. Confirm the A117.1 edition your local building code actually adopts before relying on these numbers on a specific project.
