There's also a new app that I read about that rates accessibility:

I have no personal experience with the app, just passing on some information.
Thanks for posting! The article reminded me of a wider population base:
“The app also helps people who are temporarily disabled with an injury or people who are pushing strollers and can’t go up stairs easily.”
And also I feel that people who walk their dog, where the dog can not manage stairs, can benefit too.
