With the passing of Article III of the Americans with Disabilities Act, which became law in 1992, building signage identifying permanent rooms and spaces is required to include Grade 2 Braille and letters that are raised at least 1/32″.
Despite all of the complex, ever-changing requirements, ADA compliance does not have to be complicated or expensive for you. In an effort to make compliance easy and affordable, Timely Signs creates a comprehensive line of ADA compliant signage with the most current ADA regulations.
