Handicapped accessibility effects all buildings serving the public including commercial & residential. Though existing buildings may be exempted, any change in the use may trigger compliance. In addition, if a percentage of the assessed value of a building is reached, then the entire building may be required to comply. There are several different state, federal and local regulations that may require compliance. Some of the regulations may differ from one agency to another. The goal is to have all buildings serving the public be accessible to all persons handicapped or impaired.
