The Americans with Disabilities Act (ADA) expects workplaces and public areas to be accessible for people with disabilities. Since 1990, businesses and communities strive to meet these requirements. For example, public areas must take steps to remove barriers and add domed-tile curb ramps to improve accessibility and safety for people with impairments. Buildings constructed before 1990 must make adjustments, but buildings built after 1990 must be ADA compliant.
