A Certificate of Occupancy (CO) is an official document issued by a local government or building department. It certifies that a building or property complies with all applicable building codes, zoning laws, and safety regulations. The CO is essential for ensuring that a structure is safe for occupancy and can be used for its intended purpose. Before a property can be occupied, the owner must apply for a CO after construction or significant renovations are completed. This process often involves inspections by local authorities to verify that the building meets all necessary standards. Without a valid CO, occupants may face legal issues or fines.
