This is a list of condominiums and housing cooperatives in the United States. A condominium or "condo" is a form of housing tenure and other real property where a specified part of a piece of real estate (usually of an apartment house) is individually owned. Use of land access to common facilities in the piece such as hallways, heating system, elevators, and exterior areas are executed under legal rights associated with the individual ownership. These rights are controlled by the association of owners that jointly represent ownership of the whole piece.
