On the legal side, ambiguity in the law and the speed at which technology and dependence on the Internet has developed created an opportunity for litigation all over our nation. As these cases have moved through our system, the courts have been nearly split -- with the 1st, 3rd and 7th Circuits ruling that the ADA does apply to websites, while the 6th, 9th and 11th Circuits have ruled that it does not. These latter rulings have all been based on the interpretation that the ADA is focused on physical location and requires a nexus test. Other circuit courts in the United States have yet to rule on the topic.
As I mentioned above, under each WCAG 2.1 principle is a list of guidelines, and under each guideline are compliance standards, with techniques and failure examples at each level. Some guidelines include only Level A items; others include items for multiple levels of conformance, building from A to AAA. At each stage, you can easily see what more you would need to do to reach Level AA or AAA. In this way, many websites include elements at multiple levels of accessibility.
Because they only read text, screen readers and refreshable Braille displays cannot interpret photographs, charts, color-coded information, or other graphic elements on a webpage. For this reason, a photograph of a mayor on a city’s website is inaccessible to people who use these assistive technologies, and a blind person visiting the website would be unable to tell if the image is a photo, a logo, a map, a chart, artwork, a link to another page, or even a blank page.
The Department has assembled an official online version of the 2010 Standards to bring together the information in one easy-to-access location.  It provides the scoping and technical requirements for new construction and alterations resulting from the adoption of revised 2010 Standards in the final rules for Title II (28 CFR part 35) and Title III (28 CFR part 36).
Another important consideration is that the ADA does not allow businesses to simply provide an alternative such as a phone number. Lastly, include accessibility issues as part of your website and mobile strategy. When new technologies are implemented or pages added, part of the process should include the implications for persons with disabilities. 
Consequently, the Department intends to publish a Notice of Proposed Rulemaking (NPRM) to amend its Title II regulations to expressly address the obligations of public entities to make the websites they use to provide programs, activities, or services or information to the public accessible to and usable by individuals with disabilities under the legal framework established by the ADA.
Basically, there are standards which apply to US federal agencies, and State or Local Government websites (not business/personal websites). While some disability discrimination laws do mention websites, they don’t specify the technical standards required to comply with the law. Regardless of ADA’s lack of stating websites must be fully accessible, the Department of Justice seems to rule on the side of “they should be”.

The Americans with Disabilities Act (ADA) was first passed in 1990. Twenty years later, the US Department of Justice released an update called the 2010 ADA Standards for Accessible Design. These standards cover the design of physical spaces and have been interpreted to include web locations as well, so it can be difficult for the would-be accessible website designer to use them.
As a web developer, Ryan's work is what makes the magic happen. He spends most of his time creating custom websites, which involves turning the designers' visual mockups into code. It's lucky that he's such a good problem solver, because many of Ryan's projects involve working with clients to create complex custom functions. He's also one of the few developers in the country with extensive experience developing for the HubSpot CMS.
Up-to-date standards are offered for checking compliance, and it provides a cost-effective way to scan a site for compliance. There's services out there where it'd cost more than $150 (the current cost of a 1 site 1 year license) for the size of the sites I'm working with. I'm very happy to see this offering in the first place, and it's even nicer to see how thorough it looks to be. Of course, it's not perfect so I'd love to see more of the WP.org listing fleshed out (the developer author/contributor mention is missing, etc.), I'd love to see the free version on GitHub (or similar for community development assistance [I have a few things I'd help with] which is very nice to see in a WP.org listing to show there's support / ongoing development for the plugin), and of course I'd love to see the server-side checker come to feature-parity with WAVE (currently WAVE is showing a few things the server-side checker doesn't have [color contrast, etc.]) Keep up the great work!
The Trump administration’s DOJ had previously promised to begin using WCAG 2.0 as its formal standard for web accessibility. However, the DOJ recently included this action as part of the department’s “inactive list,” which means that it’s not likely to be adopted in the near future. As a result, a clear standard to judge an organizations’ web accessibility will continue to be interpreted, and the number of ADA website lawsuits is not expected to slow down any time soon.
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. 

The Americans with Disabilities Act (ADA) and, if the government entities receive federal funding, the Rehabilitation Act of 1973 generally require that state and local governments provide qualified individuals with disabilities equal access to their programs, services, or activities unless doing so would fundamentally alter the nature of their programs, services, or activities or would impose an undue burden.2 One way to help meet these requirements is to ensure that government websites have accessible features for people with disabilities, using the simple steps described in this document. An agency with an inaccessible website may also meet its legal obligations by providing an alternative accessible way for citizens to use the programs or services, such as a staffed telephone information line. These alternatives, however, are unlikely to provide an equal degree of access in terms of hours of operation and the range of options and programs available.

Error prevention on important forms (3.3.4): For pages that create legal commitments or financial transactions or any other important data submissions, one of the following is true: 1) submissions are reversible, 2) the user has an opportunity to correct errors, and 3) confirmation is available that allows an opportunity to review and correct before submission.

Poorly designed websites can create unnecessary barriers for people with disabilities, just as poorly designed buildings prevent some people with disabilities from entering. Access problems often occur because website designers mistakenly assume that everyone sees and accesses a webpage in the same way. This mistaken assumption can frustrate assistive technologies and their users. Accessible website design recognizes these differences and does not require people to see, hear, or use a standard mouse in order to access the information and services provided.


For example, you may have thousands of images on your website that need to be checked for the presence of “alt text,” which is a requirement under WCAG 2.0. This is a task for automated testing software, which can perform the job much faster than any human. While automated tools can detect if the images on your website have alt text, however, they aren’t able to determine whether the text is correct and meaningful—which is a job for human testers.
The ADA guidelines are often updated so that businesses can better understand how various disabilities can affect the way that people will interact with websites and digital content. The guidelines also explain why certain barriers can prevent disabled individuals from using or even accessing a website. With these goals in mind, it is important to note that organizations need to review the guidelines on a yearly basis. New technologies, such as Artificial Intelligence10, are being used to help people with disabilities get the most out of the digital world. If organizations fail to read the latest ADA guidelines, then they will soon discover that their approach to web accessibility is outdated, and they might be in violation of digital accessibility laws.
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.
For most businesses, the need for ADA web compliance means they will need to make at least some adjustments to all of their online marketing strategies. For instance, if your company provides tax preparation services, all of the tax forms you provide for customers to download would need to meet accessibility standards. Any online tax preparation services that you offer would also need to be configured so they meet ADA standards, as would your mobile app.
All of that was well and good in 1990, when the then-nascent Internet was not the ubiquitous presence in the lives of Americans that it is today. For example, retail shopping in-person at a mall in 1990 was booming, unlike today where online shopping has completely changed the game for retailers. As time and technologies evolved however, the Department of Justice (DOJ), the entity charged with enforcing the ADA, hinted but never definitively stated that Title III may indeed be applicable to websites.
