You may have noticed that the law refers to federal agencies, so you might be thinking, “Well, this a federal issue -- how does this relate to a private business website, or how am I affected by this law?” Websites are now considered public entities since any user can access them via a computer or any other device. Think of this as a building requiring wheelchair-accessible ramps. The same basic principle applies to websites or any other technology.

The Americans with Disabilities Act (ADA) prohibits discrimination against people with disabilities in several areas, including employment, transportation, public accommodations, communications and access to state and local government’ programs and services. As it relates to employment, Title I of the ADA protects the rights of both employees and job seekers. The ADA also establishes requirements for telecommunications relay services. Title IV, which is regulated by the Federal Communications Commission (FCC), also requires closed captioning of federally funded public service announcements.

Video remote interpreting (VRI) is a fee-based service that uses video conferencing technology to access an off-site interpreter to provide real-time sign language or oral interpreting services for conversations between hearing people and people who are deaf or have hearing loss. The new regulations give covered entities the choice of using VRI or on-site interpreters in situations where either would be effective. VRI can be especially useful in rural areas where on-site interpreters may be difficult to obtain. Additionally, there may be some cost advantages in using VRI in certain circumstances. However, VRI will not be effective in all circumstances. For example, it will not be effective if the person who needs the interpreter has difficulty seeing the screen (either because of vision loss or because he or she cannot be properly positioned to see the screen, because of an injury or other condition). In these circumstances, an on-site interpreter may be required.
In 2001, for men of all working ages and women under 40, Current Population Survey data showed a sharp drop in the employment of disabled workers, leading at least two economists to attribute the cause to the Act.[52] By contrast, a study in 2003 found that while the Act may have led to short term reactions by employers, in the long term, there were either positive or neutral consequences for wages and employment.[53] In 2005 the rate of employment among disabled people increased to 45% of the population of disabled people.[54]
Navigable: Content that’s repeated on multiple pages can be easily skipped. All pages have informative titles, headings, and labels that describe the page’s content and hierarchy. Navigating the page must take place sequentially, in a meaningful order that preserves relationships on the page. All link text is descriptive in order to make clear where the link will take users. If users are navigating via a keyboard, the current focus of the keyboard is always highlighted and visible.
Allergies and fear of dogs are not valid reasons for denying access or refusing service to people using service animals. When a person who is allergic to dog dander and a person who uses a service animal must spend time in the same room or facility, for example, in a school classroom or at a homeless shelter, they both should be accommodated by assigning them, if possible, to different locations within the room or different rooms in the facility.
Federal law isn't the only consideration for businesses. Additionally, each state interprets the law differently. Consider the case against Netflix in 2012. Lawsuits were brought in federal court in Massachusetts and California. Netflix was accused of violating the ADA by not offering "closed captioning" options for its Internet streamed movies. Illustrating the complexity of this issue, the courts reached completely opposite decisions. Massachusetts held that Netflix must comply with the ADA, while the California court found that Netflix did not fall under the ADA's definition of "public accommodation."
