The Architectural Barriers Act (ABA) was passed in 1968 as the first measure by Congress to ensure access to the built environment for people with disabilities. The law requires that buildings or facilities that were designed, built, or altered with federal dollars or leased by federal agencies after August 12, 1968 be accessible. Facilities that predate the law generally are not covered, but alterations or leases undertaken after the law took effect can trigger coverage.
