The Online Accessibility Act would extend the Americans with Disabilities Act to require private companies to make their consumer-facing websites and mobile applications accessible to people with disabilities. Companies would need to comply with Web Content Accessibility Guidelines 2.0 Level A and Level AA standards, or provide an alternative means of access that gives disabled users equivalent access to the same content. The legislation establishes a complaint process requiring individuals to first notify a company of accessibility problems and give it 60 days to fix them before filing a complaint with the Department of Justice, which would have 180 days to investigate. If violations are found, the Attorney General can pursue civil enforcement with penalties of up to $20,000 for first violations and $50,000 for subsequent violations, and individuals can also pursue private lawsuits after exhausting administrative remedies. The Architectural and Transportation Barriers Compliance Board must issue final regulations within approximately one year, with special flexibility provisions for small businesses.
