From Point of Law:
Hans Bader , senior attorney and counsel for special projects with the Competitive Enterprise Institute, comments  on a recent New York Times story  that sheds light on a phenomenon Walter Olson  of the Cato Institute tags as the creation of "ADA filing mills." 
Bader writes :
Thanks to generous attorney-fee provisions contained in federal civil-rights law, trial lawyers are feasting on Americans with Disabilities Act claims at the expense of small businesses, consumers, and indirectly the public. As I noted earlier , a trial lawyer can collect thousands of dollars in attorney fees for "winning" a discrimination or ADA lawsuit, even if his client collects only $1.
...When it comes to ADA compliance, small businesses are subjected to legal harassment no matter what they do. Many small businesses don't have the freedom to unilaterally modify their entrances or facilities to make them handicapped-accessible, due to municipal code compliance regulations. Instead, they have to submit costly, detailed applications to code enforcers first, and sometimes have to wait months or years for approval, during which time they are sitting ducks for greedy trial lawyers bringing ADA claims. If they make their facilities ADA compliant without receiving the required municipal permits, they get fined by municipal officials.
As the owner of the Cha Cha Chicken restaurant on Pico Boulevard in Santa Monica noted, "We wanted to renovate our bathroom areas to make it more handicap-accessible and it took us almost three years to get all the permits. . .We kept giving all the paperwork they need, but it took forever. We needed the Pico Improvement Organization to plead our case."
