ADA requires more. Notice that I said "slope verses length" - because I already saw those missing numbers were not provided. Each rise also has a limit on length and other considerations. Also not mentioned is a foundation requirement.
Height of the switch is not 54 inches. That is above current switch height which is not ADA compliant. Top of a switch typically cannot be more than 44 inches due to considerations not listed.
Those west coast sites (back then) made it even easier - with diagrams instead of text for things like hot water pipe clearance beneath a sink.
Many ADA standards should be standard construction. And that is a point being obfuscated. Why should a switch at below 44 inches cost more? Standards that should be so routine as to even be available in libraries. I could repeatedly find references to how to sue - but not the numbers. I have not checked libraries in the past two years. No reason to do so. MaggieL says a book is easily obtained. She has provided book titles. Is it in any of your libraries?
Meanwhile, access-board.gov citation from orthodoc did not exist then (see its date) - or at least was not available via Google then. After reviewing a long list of sites that told me who to sue, I eventually found some numbers from some west coast government web sites. Obviously these sites would be well down the list (due to how Google prioritizes).
Having been through this ADA stuff when requirements were long established, I discovered numbers nearly impossible to find. That remains fact.
Go to an appliance store. Ask them about ADA compliant white appliances. I still do this from time to time. Same response every time. No one (yet) knew whether any appliances are ADA compliant nor how to find information defining ADA compliance. A common response was, "Nobody ever asked." Recently found appliances from Korea (LC?) that met ADA requirements. Where have the American manufacturers been this last decade when ADA compliance was long defined in America?
Want to see why some ADA requirements cost so much? Well imagine if these same people designed computers. We would still be using Windows 95. Some industries absolutely fear change. Terrain that is ripe for lawyers.
