Upon discovering issues faced by disabled government employees and the public, revisions to section 508 were made. The issues that were uncovered involved websites, documents, and software programs. As of January 2018, the updated 508 standards require all federal agencies and contractors to create web content accessible to all. The updated standards also include Website 508 compliance.
The ADA provides explicit coverage for service animals.[22][23] Guidelines have been developed not only to protect persons with disabilities but also to indemnify businesses from damages related to granting access to service animals on their premises. Businesses are allowed to ask if the animal is a service animal and ask what tasks it is trained to perform, but they are not allowed to ask the service animal to perform the task nor ask for a special ID of the animal. They cannot ask what the person's disabilities are. A person with a disability cannot be removed from the premises unless either of two things happen: the animal is out of control and its owner cannot get it under control (e.g. a dog barking uncontrollably in a restaurant), or the animal is a direct threat to people's health and safety. Allergies and fear of animals would not be considered a threat to people's health and safety, so it would not be a valid reason to deny access to people with service animals. Businesses that prepare or serve food must allow service animals and their owners on the premises even if state or local health laws otherwise prohibit animals on the premises. In this case, businesses that prepare or serve food are not required to provide care or food for service animals, nor do they have to provide a designated area for the service animal to relieve itself. Lastly, people that require service dogs cannot be charged an extra fee for their service dog or be treated unfairly, for example, being isolated from people at a restaurant. People with disabilities cannot be treated as "less than" other customers. However, if a business normally charges for damages caused by the person to property, the customer with a disability will be charged for his/her service animal's damages to the property.

This title outlines the administrative processes to be followed, including requirements for self-evaluation and planning; requirements for making reasonable modifications to policies, practices, and procedures where necessary to avoid discrimination; architectural barriers to be identified; and the need for effective communication with people with hearing, vision and speech disabilities. This title is regulated and enforced by the U.S. Department of Justice.
Case law has been the most helpful in illuminating the implications of the ADA for websites.There have been lawsuits involving companies like Expedia, Hotels.com, Southwest Airlines, and Target as defendants and primarily featuring accessibility organizations as plaintiffs. These cases had mixed results, but each helped clarify the ADA's jurisdiction on the web. 
Most recently, however, pizza chain Domino's has been brought under suit for their website not being accessible for specialty ordering. The U.S. Supreme Court refused to review the case, instead upholding the decision of the 9th U.S. Circuit Court of Appeals who said the “alleged inaccessibility of Domino’s website and app impedes access to the goods and services of its physical pizza franchises—which are places of public accommodation.”
