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 Oregon, condominiums are regulated under the Oregon Condominium Act (ORS Chapter 100). This law outlines the creation, sale, and operation of condominiums within the state. 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 governance of a condominium is typically handled by a homeowners' association (HOA), which operates through a board of directors elected by the unit owners. The HOA is responsible for the enforcement of the rules set forth in the declaration and bylaws of the condominium. Unit owners are required to pay monthly dues to the HOA for the upkeep, maintenance, and insurance of the common areas. These regulations ensure that the rights and responsibilities of all parties involved in condominium living are clearly defined and maintained.
