Without a valid OC, your occupancy is illegal as it can be classified as an unauthorised structure by the authorities. OC is crucial while applying for a home loan or loan to purchase a resale flat. You cannot even sell your property without a valid OC in hand. No Occupancy Certificate means that the building has not been given a “Pass Certificate”. This means that it does not have all the mandatory infrastructure/ clearances that make the building inhabitable. It is like you saying you have completed your degree but you do not have a Degree Certificate to show for it. Without OC, the building is technically... See more unfit for occupation and hence in the event that any accident takes place, the occupants / users of the building can hold no one liable and would not be eligible for any insurance or compensation claims. Water, sanitary and electricity connections, if already obtained, are liable to get disconnected. Presently, OC is not mandatory for registering the sale of flats in Bangalore. However, the khata for the flat will not be issued unless the building has the OC. The flat also cannot be sold without the OC. Good luck with your new search. Hope you find the flat with all legalized and safe registrations.
