The legal issue for websites is whether website operators are operating “a place of public accommodation.” The statute lists 12 different types of public accommodations including somewhat of a catchall that includes “other sales or rental establishment.” The list, created when the law was passed in 1988, conceivably covers most commercial establishments, but does not expressly include websites.
While legal considerations might be your biggest worry, making your site more accessible is simply good customer service. More than 39 million Americans are blind and another 246 million have "low vision," Another one million are deaf in the U.S. Add to that people with mobility issues that prevent them from using their hands and that's a huge portion of the country's buying power.
According to the DOJ, “Being unable to access websites puts individuals with disabilities at a great disadvantage in today’s society.” With these words in mind, the DOJ has rapidly adopted the role of web accessibility enforcer. A failure to make digital content, including websites, accessible to all individuals regardless of their emotional, physical, or mental disabilities, can result in hefty fines and class action lawsuits. In short, the DOJ is dedicated to making sure that individuals with disabilities have the same equal access to the benefits that are available online. Creating equal access is only possible if organizations a) understand the requirements of web accessibility, b) know that web accessibility is an obligation under the ADA, and c) make web accessibility a priority. The value that awaits when organizations adhere to digital accessibility laws can be measured in more than dollars and cents.

In an August 2016 case involving the University of California Berkeley, the DOJ ruled that the public university was in violation of ADA Title II (similar to Title III but it instead applies to government organizations) because their YouTube channel’s videos didn’t include captions for hearing impaired visitors. The DOJ found this to violate the ADA as deaf users did not have equal access to the online content.
The ADA is the Americans with Disabilities Act, passed almost 30 years ago in 1990. This act was originally put in motion pertaining solely to physical location. It requires establishments to provide people with disabilities easy access to various levels throughout the business. This act was set to achieve an equal experience to all people, handicapped or not.
