American Disabilities Act. It is higher than a standard toilet
Any apartment which has been modified to accommodate a disabled person would be considered an ADA modified apartment. The Americans with Disability Act, or ADA is a law which mandates that apartments must be modified to accommodate a disabled tenant. Any apartment that is subsidized by the federal government in any way, such as an LIHTC, requires that its owner pays for this. Conventional apartments, on the other hand, have the option of paying for it or allowing the tenant to pay for it, depending on the cost. Most ADA modified apartments are modified for wheelchair access, though many can be just as simple as having a raised toilet and grab bars.
