If there is no OC, the Local Body can also take action against the flat owners, as the law says no person can move into a building without the OC. Such cases have been seen in Mumbai and Delhi real estate markets. The classic example is the Campa Cola case in Mumbai.
Hi, OC certifies that the building has obeyed with the approved plans. The OC from the planning authority is essential for any construction as per the provision of law. A buyer can move into his/her new apartment only once the OC has been received. It is mandatory for a builder to possess this document before beginning construction of a property. These certificates are evidences that the commencement and completion of the building are as per the approved plan and in compliance of locals laws.
