Disability accommodations tend to also strongly benefit everyone else. I know this isn't a code thing, but the most useful one I can think of is curb cuts.
Speaking of curb cuts, recently in my town, they ripped up the sidewalks with already existing curb cuts, and added a new yellow pad with raised bumps in addition to new curbs (with the cuts). I was going to ask what this was for, but a quick search indicates that it is likely for blind users to feel the end of the sidewalk with a cane.
Those also have good traction. On a winter morning before anyone gets around to shoveling, those pads might be the only good surfaces on my entire commute. The street corner where cars are turning is a pretty good spot not to be slipping.
Not sure why this comment is being downvoted. Thinking about accessibility is likely to positively impact your product or service's user experience. Not everyone has low/no vision or uses a switch device, but keeping those users in mind will allow abled folks to benefit from your design choices as well. Have you ever used a UI and complained that elements provide ideal contrast, or that you're able to use your keyboard for interactions?
