The Inclusive Design Guidelines, New York City, Second Edition confirms that it is a living document and that Inclusive Design is dynamic. The premise of the book holds true: “The IDG is voluntary technical guidance helping designers produce multisensory enhanced environments that accommodate a wide range of physical and mental abilities for people of all ages.” Adoption of the ICC A117.1 standard has proven to be correct because of its relevant content, structure, numbering system and harmonization with the New York City Building Code, the 2010 ADA Standards, and other legal requirements. Expansion and refinements of this edition comprise 25% new content; 15% updates, and two hundred forty (240) additional figures.
