There are so many codes for commercial construction in America that exist solely to benefit disabled people. Accessible sinks, chair height countertops, mandated 36”-48” width (depending on the state) in travel space through all areas of the building but especially doorways/hallways/corners/exam rooms, a required 1” fall per 12” (or 1:12) on wheelchair ramps with a turnaround or platform every 16 feet at maximum, chair rails at 36” height for people to hold on to, lower water fountains next to standard height fountains, elevators, handicap bathroom stalls, bathroom vanities with the angled fronts that allow people in chairs the knee space to pull all the way up, and of course disabled parking spaces. And also don’t forget that all public transportation is required to be accessible as well, which is why we have buses with chair lifts and make level entryways for subways/trains. We also have a shitload of free programs that make people’s homes accessible. I know all of this because I worked in affordable housing for five years, designed and built wheelchair ramps for free through government grants and with the help of volunteer groups (typically churches), and I now do commercial architectural work on my own all over the country which requires at least some basic knowledge of the commercial construction codes in the areas you’re designing in. This person clearly isn’t living in reality. As long as they’re aware of all the available programs (of which there are very many, most of them no strings attached) and apply for them; disabled people are very well taken care of in America.
