Accessibility Codes & Standards

    Here's a good way of looking at this that I think can help you:

    1) Chapter 11 of IBC covers the Scoping Requirements for accessibility.  Essentially, it tells you WHEN you have to make various elements throughout your building accessible.  Examples would be when you have to provide an accessible route, when you have to make certain rooms accessible, when you have to design restrooms to be accessible, etc.

    2) Once you've determined in Chapter 11 that something in your project needs to be accessible, ANSI and ADA then tell you HOW to go about doing that.  IBC Chapter 11 tells you "you must make this restroom accessible."  You then turn to ANSI and ADA for all the diagrams about floor clearances, grab bars, sink heights, fixture locations, etc.  that you must include to make that restroom accessible. 

    3) I would offer to you that ANSI and ADA are very, very, very close to the same documents.  Me personally, I studied ANSI A117 and it was just fine.  I do not believe that the typical diagrams you encounter for accessibility - door approaches, fixture clearances, minimum required floor spaces, etc. - differ between these two documents AT ALL.  I have not experience this in my work and I have been doing code research for my office for 10 years +.
