This rulemaking would amend the Americans with Disabilities Act (ADA) and Architectural Barriers Act (ABA) Accessibility Guidelines to specifically address emergency transportable housing units provided by the Federal Emergency Management Agency (FEMA) or other entities on a temporary site in response to an emergency need for temporary housing. The rulemaking seeks to ensure that newly constructed and altered emergency transportable housing units covered by the ADA or ABA are readily accessible to and usable by individuals with disabilities. The U.S. Department of Justice (DOJ) issued enforceable accessibility standards for residential facilities covered by the ADA, and the U.S. Department of Housing and Urban Development (HUD) has issued enforceable accessibility standards for residential facilities covered by the ABA. DOJ and HUD are expected to update their standards in separate rulemakings to be consistent with the amended guidelines.
