Are Condos covered by the Fair Housing Act?I'm often asked whether a condo that is privately owned falls under the Fair Housing Act. If the condos are located in a building that houses four or more units, then those condos are "covered" by Fair Housing Act. (Covered by the Act means that those units must comply with the guidelines)Regardless of whether you rent or own, the following is the criteria for what buildings are covered by the Fair Housing Act:1. In buildings without an elevator, only the ground floor units are covered2. In buildings with an elevator, all units are covered3. In building with an elevator, but with some units that have two stories, then only the units that are accessed via an elevator like the figure below, are covered and must comply.
