A condominium project is one of the four types of CIDs that are considered common interest developments in Civil Code section 4100. A planned development is defined in Civil Code section 4175 as a common interest development other than a community apartment project, condominium project, or stock cooperative. It also must have either or both of the following characteristics: (1) common area that is owned either by an association or in common by the owners of the separate interests who possess appurtenant rights to the beneficial use and enjoyment of the common area, and/or (2) common area and an association that maintains the common area with the power to levy assessments that may become a lien upon the separate interests. The owners’ separate interests are typically platted lots.
