What does the Americans with Disabilities Act require for housing?

The Americans with Disabilities Act, or ADA, primarily covers commercial facilities and public accommodations rather than private housing. However, the Fair Housing Amendments Act of 1988 addresses disability in housing by requiring that multifamily buildings with four or more units built after March 1991 include accessible design features such as accessible entrances, doors wide enough for wheelchairs, accessible routes, reinforced bathroom walls for grab bars, and accessible kitchens and bathrooms.
