Under the Americans with Disabilities Act of 1990 (ADA), businesses and certain government buildings are required to take steps to make their buildings accessible to those who are handicapped. Provisions may include elevators, wider doorways that can accommodate wheelchairs and, in certain cases, wheelchair ramps. Certain exemptions are afforded to buildings on the basis of design or historic integrity. The U.S. Department of Justice has established an easy process for reporting problems.
Older buildings before 1990 have no handicap requirements, however, each state or city can make
up their own laws or requirements and enforce them.
