The Access Board of the Architectural and Transportation Barriers Compliance Board has issued this guide to assist in the use of its American with Disabilities Act Accessibility Guidelines (ADAAG) for buildings and facilities. It explains some of the basic considerations for accessible design and clarifies specific ADAAG provisions. Advisory information is provided in the form of recommendations that are optional and go beyond the minimum required by ADAAG. Information is categorized under the main areas of scoping and technical requirements for specific building areas such as toilet facilities, curb ramps, entrances, and elevators; and special occupancies covering dining facilities, medical facilities, libraries, and accessible transient lodging. Diagrams, layouts, and other illustrations are contained throughout the guide. (GR)
