Real estate is a vast sector brimming with a number of legal compliance that at times may leave first-time homebuyers confused. Among many documents that determine the legality and usability of a property, the Completion Certificate (CC) and the Occupancy Certificate (OC) stand extremely important. These certificates are issued by local municipal or development authorities to buildings that are legally constructed and are safe for living. Let’s take a closer look at these closely.Completion Certificate (CC)A Completion Certificate (CC) is issued after the construction of a building is completed. It must be done lawfully with the approved building plans, rules and regulations. This certificate confirms that the developer has followed the sanctioned layout (such as height, and zoning regulations) mentioned at the time of approval.To obtain a CC, the developer must show:Approved floor plans Approved height Safety normsFire safety Environmental and zoning regulationsParking Common area Occupancy Certificate (OC)An Occupancy Certificate (OC) is issued to a building after its completion. It means that the building is fit for occupancy. The certificate confirms that the property complies with all essential infrastructure requirements including water supply, electricity, sewage and drainage systems, among other safety requirements. The OC is a primary document as it legally permits people to live in the building. A number of states consider it illegal to live without an OC.Difference between CC and OCThe two certificates are different and serve different purposes. The one thing that’s common is that both are issued by local authorities. While the CC is the verification of the completion of the construction as per approved plans, the OC confirms that the building is safe and ready for occupation. The CC is more about the construction compliance and the OC is about the occupancy readiness of the building. Importance of CC and OC in property purchaseLegal terms: A building without a CC may be classified as unauthorised construction, while an OC is deemed illegal for occupancy. Both situations can end up in legal complications.Services: All the major services such as water connections, sewage systems, electricity and gas meters are sanctioned only after the society gets an OC.Home loans: Even to get approval for loans, one needs to show the CC and OC.Resale Value: Buyers are now cautious and avoid properties missing these certifications.So, if you are someone planning to buy a property, do not miss out on checking the Completion Certificate and Occupancy Certificate as these are fundamental documents which secure your legal standing and long-term property value. In case you ignore these certificates, you may get involved in legal issues and financial losses in the future.
