Does the ADA permit an individual with a disability to sue a business when that individual believes that discrimination is about to occur, or must the individual wait for the discrimination to occur?

The ADA public accommodations provisions permit an individual to allege discrimination based on a reasonable belief that discrimination is about to occur. This provision, for example, allows a person who uses a wheelchair to challenge the planned construction of a new place of public accommodation, such as a shopping mall, that would not be accessible to individuals who use wheelchairs. The resolution of such challenges prior to the construction of an inaccessible facility would enable any necessary remedial measures to be incorporated in the building at the planning stage, when such changes would be relatively inexpensive.
