Occupancy Certificate (OC)
The municipal certificate declaring a completed building safe and legal to occupy — never take possession of a new flat without it.
Definition
An Occupancy Certificate (OC) is issued by the local municipal corporation or development authority after construction is complete, certifying that the building is fit for habitation: it conforms to the sanctioned plan and building byelaws, and essential services — water supply, sewerage, electricity, fire-safety systems, lifts and access — are in place. It is the legal green light to occupy the building.
For a homebuyer the OC is one of the most important documents in a new project. Under RERA, the promoter must obtain the occupancy/completion certificate before offering possession to buyers. Without an OC the occupation is technically unauthorized: many cities refuse permanent water and electricity connections to buildings lacking an OC, authorities can levy penalties or, in extreme cases, act against the building, banks are reluctant to lend against such flats, and resale becomes harder.
The builder (not the buyer) applies for the OC from the sanctioning authority — for example the municipal corporation or development authority of the city — after construction and inspections; buyers should demand a copy of the OC before taking possession and paying the final instalment. Many authorities now publish or verify OCs online, and a project's OC status is also visible on state RERA portal records.
Pitfalls: do not confuse the OC with the Completion Certificate (CC) — the CC certifies that construction matches the approved plan, while the OC certifies the building is fit and lawful to occupy; the CC comes first and the OC follows. Also beware of taking possession on the strength of 'applied for OC' promises: the practical risks (utility connections, penalties, financing and resale problems) fall on the occupant, not the builder.
Example
Meera refused to take possession of her new flat until the builder shared the Occupancy Certificate issued by the municipal authority, since without it the tower could not get permanent water and power connections.
