I should mention one caveat to all of this. Businesses that are required to comply but don't have the ability to bring their websites into compliance can provide an accessible alternative to provide the same information, goods, and services that they provide online, like a staffed phone line. The trick, however, is that this option has to provide at least equal access, including in terms of hours of operation. And, as we know, the internet is around 24/7, so good luck with that. 
Hey OB – Disclaimer – none of this is legal advice and you’d want to check with a lawyer to know if you’re at risk for any action if you’re not ADA compliant. Based on what we’ve seen if you don’t have a physical retail or service location, and you don’t receive any funding from the government you likely aren’t required to have a website that would be considered compliant. Some people expect that to change in the next few years, but that’s what we know for now. Let us know if you have more questions or would like to test your site.
These statistics are especially important when you consider the potential spending power of people with disabilities. Unfortunately, if the website isn’t accessible, then it is excluding more than 60 million Americans14. Additionally, 71 percent of customers14 with disabilities will instantly leave the site if it does not meet their accessibility needs. Another 80 percent of customers14 with disabilities have stated that they will spend more on a website that has improved accessibility features. Fortunately, if you follow Web Content Accessibility Guidelines (WCAG)7, then you can appeal to millions of individuals who want to enjoy the same online experiences as their friends, family, and neighbors. Giving them the chance is not only right, but it is also in accordance with ADA regulations.
The Department of Justice published revised final regulations implementing the Americans with Disabilities Act (ADA) for title II (State and local government services) and title III (public accommodations and commercial facilities) on September 15, 2010, in the Federal Register. These requirements, or rules, clarify and refine issues that have arisen over the past 20 years and contain new, and updated, requirements, including the 2010 Standards for Accessible Design (2010 Standards).

The DOJ is currently working to release new technical standards for digital accessibility. The latter updates to the ADA guidelines will be in conjunction with the latest version of WCAG 2.1, which includes the most widely accepted digital accessibility requirements across the globe. If organizations want to overcome the current limitations of ADA guidelines, then they should follow the WCAG 2.1 checklist,11 as well as the suggestions provided by the ADA. The latter two steps, combined with the help of a trusted digital accessibility compliance platform,12 can help organizations achieve digital accessibility best in class standards throughout all of their digital formats and across all media.
Penn in particular nearly made the cut because I really like their keyboard accessibility. It amazes me how few sites provide visible indication of keyboard focus, when it's incredibly simple to achieve (just add a style for a:focus in your style sheet). Penn did this, and consequently it's very easy for sighted keyboard users to keep track of their position as they tab through the page. They also included a keyboard-accessible dropdown menu. However, there are some dynamic features on the Penn home page that really need ARIA markup for full accessibility. They also have a few contrast problems, most notably their slideshow navigation, which is red-on-red:

Hey Casey, this is one of the areas where things get a little weird because the W3 doesn’t actually have any say over the ADA guidelines, it is more than the ADA guidelines adopted the WCAG 2.0 guidelines as just that, a guideline to help. As far as I know, the tool you’ve linked to hasn’t been used in any judgements I’m aware of. Usually when it comes down to making a decision on if something is/isn’t compliant they have people use the actual PAWS tools and show what elements do/don’t work as intended or are otherwise inaccessible. Hope this helps!
