An occupancy certificate (OC) is the city’s confirmation that a building has been completed in line with its sanctioned plan and is fit to be lived in. In Bangalore, many disputes between flat buyers and builders come down to a missing or partial OC. This guide explains what an OC is, how it differs from the commencement certificate, why buying a flat without one is risky, and what you can do if your builder has not obtained it.
Sanctioned Plan, Commencement Certificate and OC
Building approval in Bangalore happens in stages:
- Sanctioned building plan: the city or planning authority approves the plan, including floors, setbacks and use.
- Commencement certificate (CC): issued once construction is allowed to start, typically after the foundation stage is inspected.
- Occupancy certificate (OC): issued after construction is complete and the building has been inspected against the sanctioned plan and safety requirements.
Inside city limits, these approvals are now issued by the city corporations under the Greater Bengaluru Authority, which replaced the BBMP in 2025. Outside city limits, the relevant planning authority or local body issues them.
Why a Missing OC Is a Problem
Without an OC, the building is not treated as fully legal for occupation. In practice that can mean:
- Difficulty getting a khata or e-Khata for your flat.
- Problems with permanent electricity and water connections. Utilities have generally asked for an OC, although the state has relaxed this for some smaller residential buildings, so check the current rule.
- Banks hesitating to lend to future buyers, which makes resale harder.
- Penalties or action if floors or areas were built beyond the sanctioned plan.
Partial OC and Deviations
Large projects are often built in phases, and the authority may issue a partial OC for completed towers or floors. If you are buying in a phase that is not covered by an OC, treat it as an under-construction purchase, with the same checks and protections.
Many buildings in Bangalore also have deviations from the sanctioned plan, such as an extra floor, reduced setbacks or a change of use. Minor deviations may be condoned on payment of a penalty. Major ones can block the OC entirely or lead to demolition notices. Ask your lawyer to compare the building on the ground with the sanctioned plan before you buy.
Checks to Make Before You Buy
- Ask for copies of the sanctioned plan, the CC and the OC, and check that the OC covers your tower and floor.
- Compare the number of floors and units in the OC with what has actually been built.
- For new projects, check the RERA registration and the completion date the builder has declared.
- For resale flats, check that the khata, tax receipts and utility connections are in the seller’s name.
These checks form part of a full title verification. See our document verification checklist.
If Your Builder Has Not Obtained the OC
If you bought in a RERA-registered project and the builder has handed over possession without an OC, or is delaying it, you may be able to file a complaint with the Karnataka RERA authority. Consumer commissions have also treated failure to obtain an OC as a deficiency in service. Before you complain, collect the agreement, payment receipts, possession letter and all correspondence with the builder. Our guide to RERA complaints in Karnataka explains the process.
Frequently Asked Questions
Can I register a flat that has no occupancy certificate?
Registration may still go through in some cases, but you take on the risk. Khata, utilities, loans and resale can all become harder. Take legal advice before buying.
Who issues the OC in Bangalore?
Inside city limits, the city corporation under the Greater Bengaluru Authority. Outside the city, the relevant planning authority or local body.
What is a partial OC?
An OC issued for part of a project, such as completed towers or floors, while the rest is still being built. Check that it covers your unit.
Can I complain if my builder has not obtained the OC?
Yes. If the project is registered with RERA, you can complain to the Karnataka RERA authority. A consumer complaint may also be possible.
