The Access Board provides technical guidance on its accessibility guidelines and standards and accessible design through its toll-free helpline at 1-800-872-2253 and by email at ta@access-board.gov from 10:00 a.m. to 5:00 p.m. (ET) weekdays. Accessibility specialists are available to answer questions on accessibility as it relates to the built environment, outdoor sites, streets and sidewalks, transportation vehicles and vessels, information and communication technology, and medical diagnostic equipment.
The Access Board develops and maintains design criteria for the built environment, transit vehicles, information and communication technology, and medical diagnostic equipment under the Americans with Disabilities Act (ADA), the Architectural Barriers Act (ABA), and other laws.
The Board also provides ADA and ABA guides that explain requirements in the current editions of the ADA Guidelines and ABA Standards. The guides offer clearly labeled recommendations for best practices that exceed the minimum requirements. In addition, the Board provides animations to help design professionals understand the reason and method of application of the requirements in the standards.
