A more thorough explanation:

Definition: CIDs, or common interest developments, are types of property developments that have multiple owners and a governing association. Each owner in a CID has their own property with rights to the common area. CIDs are often used for both business and residential purposes, such as malls and condominiums. However, most legal issues involving CIDs arise from restrictions and management by the governing association, such as a HOA. Governing associations often have many requirements that an owner must enter into as part of purchasing their property, and the governing association can enforce these restrictions through fines, penalties, and sometimes even eviction. While generally these restrictions will be considered legally enforceable, federal and state laws limit some restrictions in CIDs even if they were agreed to. For example, federal and state laws may require CIDs to allow an individual with disabilities the ability to keep an animal even if the CID rules forbid animals from being on the property.

Example: A condominium complex is a common example of a CID. Each owner has their own unit, but they share common areas such as hallways, elevators, and parking lots. The governing association, usually a HOA, sets rules and regulations for the complex, such as noise restrictions and maintenance requirements. If an owner violates these rules, the governing association can enforce them through fines or other penalties.

Explanation: The example of a condominium complex illustrates the definition of a CID because it has multiple owners who each have their own property with rights to the common area. The governing association, in this case a HOA, sets rules and regulations for the complex and can enforce them through fines or other penalties. This is a common issue in CIDs, where the governing association has a lot of power over the individual owners.
