24 CFR Part 100—Supplement to Notice of Fair Housing Accessibility Guidelines: Questions and Answers about the Guidelines

2.1 Q. If a building includes three residential dwelling units and one or more commercial spaces, is the building a covered multifamily dwelling under the Fair Housing Act?

A. No. Covered multifamily dwellings are buildings consisting of four or more dwelling units, if such buildings have one or more elevators; and ground floor dwelling units in other buildings consisting of four or more dwelling units. Commercial space does not meet the definition of dwelling unit. Note, however, that title III of the ADA applies to public accommodations and commercial facilities, therefore an independent determination should be made regarding applicability of the ADA to the commercial space in such a building (see the introduction to these questions and answers, which provides some background on the ADA).
