Completion Certificate vs Occupancy Certificate
| Factor | Completion Certificate (CC) | Occupancy Certificate (OC) |
|---|---|---|
| What it certifies | Building constructed as per approved plan — structural compliance verified | Building safe for occupation — all services (water, electricity, drainage) connected |
| When issued | After structural completion — before services may be connected | After all services connected and safety checks complete |
| Who can apply | Builder/developer | Builder/developer (after obtaining CC in many states) |
| Required for GST exemption | Not sufficient alone in most states | Yes — OC makes property "ready-to-move" exempt from 5% GST |
| Required for home loan | Partial — some banks accept CC for disbursement | Required for full loan disbursement and resale loans |
| Combined document | Some states (Karnataka, Telangana) issue a single Combined CC+OC | |
What Buyers Should Verify
CC and OC Verification Checklist
- Ask the builder: "Do you have OC for the building?" — builder must provide under RERA
- Check RERA portal: OC/CC must be uploaded on project page once obtained
- Verify issuing authority: OC must be from the local planning authority — not just a letter from the builder
- Match to building: OC must cover your specific tower/phase if multi-phase project
- Date matters: OC must be obtained before your possession date
- Resale check: For resale, ask seller for OC — verify it covers the building
"Possession without OC" is risky: Some builders hand over possession before getting OC. Legally, this means you occupy an under-construction building — GST at 5% still applies, home loan disbursement may be incomplete, and you have no legal protection for occupation. Always insist on OC before taking possession or paying the final instalment.

Frequently Asked Questions
A Completion Certificate (CC) is issued by the local planning authority certifying that a building has been constructed as per the approved plan. It confirms structural compliance. An Occupancy Certificate (OC) goes further — it certifies all services are connected and the building is safe for occupation. Both are important; OC is more critical for buyers.
CC (Completion Certificate) certifies the building is structurally complete as per the approved plan. OC (Occupancy Certificate) certifies all essential services (water, electricity, drainage) are connected and the building is safe to occupy. Some states combine them into a single certificate. For GST exemption and home loan purposes, OC is the relevant document.
Yes — OC is crucial. Without OC: GST at 5% still applies on the property (not exempt), banks may not complete full loan disbursement, and legally the building is considered under-construction. Under RERA, a builder must obtain OC before handing over possession. Always demand OC before taking possession or releasing final payment.
Ask the builder for a copy of the OC — they must provide it under RERA. Check the project page on your state's RERA portal — OC should be uploaded once obtained. For resale properties, ask the seller for the OC and verify it was issued by the local planning authority (not just a builder's self-declaration). Match the building number and address on the OC with your flat.
Legally, without OC the building is not certified as safe for occupation. Moving in before OC means: no water/electricity connections through the proper municipal channels, building not legally recognised as residential, GST still applicable, and home loan may not be fully disbursed. In practice many builders hand over possession before OC — but this carries legal and financial risk. Insist on OC before final payment.
