The occupancy certificate — what it is and why a buyer should refuse possession without it

An occupancy certificate, or OC, is issued by the local municipal authority once a building has been inspected and confirmed to be constructed in accordance with the sanctioned plan. Without it, a building is — in the eyes of the local body — not legally fit to be occupied. And yet thousands of Indian buyers each year take possession of flats with no OC in hand, on the strength of a builder's verbal assurance that it is 'coming next month'.

What the OC actually certifies

The OC confirms three things. First, that the construction matches the approved plan in setbacks, height, floor area and number of units. Second, that statutory clearances — fire, environmental, lift, water, sewage — are in place. Third, that the building complies with the local building byelaws. Until the OC issues, the building is technically an unauthorised construction.

How to check whether a building has a valid OC

Do not accept 'the OC is done' as a statement. Ask for the certificate itself and verify it before you take possession or pay the final instalment. The checks below separate a genuine OC from a part-completion letter or a promise.

1. Get a copy of the OC and read what it covers. It should name the specific building or block, reference the sanctioned plan number, be issued by the local municipal authority (in Bangalore that is now the GBA, formerly BBMP; elsewhere the municipal corporation or development authority), and be dated after construction was completed.
2. Confirm it is a full OC, not a partial or provisional one. A part-occupancy certificate covers only some towers or floors; an OC for Block A does not cover your flat in Block C.
3. Cross-check the OC against the project's RERA registration. The promoter files OC status with the state RERA authority, so the regulator's project page is a second, independent source for whether the OC has actually been obtained.
4. Verify with the issuing authority. The municipal body that issued the OC can confirm it was genuinely granted — a buyer or lawyer can check the OC's authenticity with the corporation rather than relying on the builder's copy alone.
5. Pull a fresh encumbrance certificate and the khata or municipal tax record. A building assessed at penal rates or flagged as unauthorised in the municipal record is a sign the OC has not issued.

Consequences of taking possession without an OC

• Property tax and electricity tariffs are charged at penal (commercial) rates in most states until the OC issues
• Resale becomes legally difficult — banks may refuse home loans, and prudent buyers will refuse to purchase
• The local body can demolish or seal unauthorised portions, including penthouses, balconies and additional floors that deviate from the sanctioned plan
• Society formation and conveyance from the builder cannot be completed in many states without OC
• Insurance claims for the property can be contested if the building is unauthorised at the time of loss

What to do if the builder cannot produce an OC at possession

Do not sign the possession letter. Section 17 of the RERA Act requires the promoter to obtain the OC before handing over possession. Taking possession without it does not extinguish the right to claim — but it shifts the practical leverage to the builder and creates documentary ambiguity. Insist on the OC in writing, and if it is genuinely delayed for reasons beyond the builder's control, document that in correspondence before agreeing to a conditional handover.
