Accessibility is like replacing steps with ramps and making it easier to access a business. This isn’t really a major problem.
The problem is attorneys filing shakedown suits at small businesses that have no real merit. A good law can be abused for nefarious ends.
The specifications are very exact and they change a lot to become more specific.
If businesses remodel they can get sued if they are not strictly following ADA - many businesses don’t remodel because of it.
You’re off by a half an inch - you’re in trouble.
Almost 9 years ago we moved our travel agency from a plaza to a residence that we converted to a business building. There were 3 steps at the main entrance. The county made us put a ramp in. Because of the restrictions on the degree of incline we had to build half of it in one direction and the other half going the other way. Cost for this ramp was $12,000 and in 9 years it has never been used!!!!
