No occupancy certificate means that the building has not been given a 'Pass Certificate' by the concerned authority. As such, it does not have all the mandatory infrastructure or clearances that make the building inhabitable.
Occupancy Certificate is mandatory for any builder before he allows people to take possession of the property. This certificate was made compulsory by the BBMP to ensure proper construction in the city.The occupancy certificate is obtained at the end of the construction. Once the builder applies for the certificate an inspection is done to check if the construction has happened according to the sanctioned plan.
