A condominium is a single unit of real estate—usually a home or residence—in a multi-unit residential development in which each owner of a unit has both a separate ownership interest (often everything inside the front door)—and a common ownership interest (with other unit owners) in the common areas of the property outside the front door—such as roofs, hallways, driveways, walkways, stairways, stucco, brick, paint, stone, and landscaping.

A condominium development is usually governed by a homeowners’ association (HOA) through its board of directors, elected by the homeowners as provided by the HOA’s declaration and bylaws. Unit owners or homeowners in the association are required to pay monthly HOA dues for the maintenance and repair of the common areas of the property and its insurance.

In Delaware, condominiums are regulated under the Delaware Unit Property Act and the Delaware Uniform Common Interest Ownership Act (DUCIOA). These laws provide the framework for the creation, management, and governance of condominiums. Each condominium unit owner has an individual ownership interest in their unit and a shared interest in the common elements of the property, such as lobbies, roofs, and other amenities. The homeowners' association (HOA), typically managed by a board of directors elected by the unit owners, is responsible for the upkeep of these common areas. The HOA's declaration and bylaws, which are binding documents, outline the rules for the community, the responsibilities of the HOA, and the obligations of the unit owners, including the payment of monthly dues for maintenance, repair, and insurance of common areas. Unit owners in Delaware are required to comply with these regulations and pay the associated fees to ensure the proper management and maintenance of the condominium development.
