The ANSI A117.1 is a document that sets standards for accessibility in new construction and remodels. It was first published in 1961 and has gone through several rounds of updates but it is still a voluntary standard. What makes it enforceable is that it is referenced in building codes, including the International Building Code. It has also been adopted as code by many State and local agencies. In addition, ANSI A117.1 has served as the basis for most of the accessibility standards adopted by Federal and State governments.
