The occupancy certificate is the document that says a building is safe and legal to live in. Here is what it means, who issues it and why every buyer should ask for it.

THE SHORT ANSWER
An occupancy certificate (OC) is issued by the local municipal authority after a building is completed as per the approved plans, confirming it is fit for occupation. In Chembur and Kurla that authority is the BMC, and in Thane it is the Thane Municipal Corporation. Without an OC, a buyer can face difficulty in getting the final loan instalment, permanent utility connections and a clean resale.
KEY TAKEAWAYS
01. The OC confirms completion as per approved plans and safety compliance. It is separate from the commencement certificate.
02. The municipal body issues it, after inspection and supporting approvals such as fire.
03. Banks often hold back the final loan disbursement until the OC is in place.
04. A ready flat with an OC attracts no GST, while an under-construction flat attracts 5% in the non-affordable segment.
05. A part OC covers only some floors or wings. Ask exactly what it covers.
What is an occupancy certificate?
An occupancy certificate is an official document issued by the local planning or municipal authority. It states that the building has been constructed according to the approved plans and applicable rules, and is fit to be occupied. The occupancy certificate meaning is simple: it is the permission to move in.
It matters because a building can be physically ready but still not legally ready. The OC is the proof that the authority has inspected and accepted the work.
Who issues an OC in Mumbai?
The municipal corporation of the area issues it. For Chembur and Kurla, that is the Brihanmumbai Municipal Corporation, and you can start at the BMC portal. For Thane projects it is the Thane Municipal Corporation. The developer applies after completion, along with the supporting documents and approvals.
Buyers do not apply for it. What buyers should do is ask for a copy, check the date and confirm it covers their wing and floor.
Which documents are required for occupancy certificate approval?
Requirements are set by the local authority and can change, so treat this as a typical list that the developer’s team handles.
- Application with the commencement certificate and sanctioned plans.
- Completion certificate or architect’s certificate stating the work follows the approved plans.
- Fire department no objection, where applicable.
- Structural engineer’s certificate.
- Water, drainage and other relevant no objections.
- Photographs of the completed building and a built-up area statement.
- Proof that statutory charges and premiums have been paid.
The practical lesson for you is that the OC depends on many approvals. If the OC is delayed, ask which of those is pending.
We tell every buyer that the OC is the finish line of the paperwork, not a formality. Ask when it is expected and what approvals it depends on, and ask for it again when you take possession.
Occupancy certificate vs completion certificate: how do they differ from the commencement certificate?
Certificate | When it is issued | What it allows |
Commencement certificate | Before construction begins | Permission to start building up to the approved stage |
Completion certificate | After construction is finished, certified by the architect and engineer | Confirms the work follows the approved plans |
Occupancy certificate | After inspection and approvals by the municipal body | Permission to occupy the building |
We spell all three out here because abbreviations lead to confusion. Our checklist of documents to check before buying a flat in Mumbai shows where each fits.
What is the importance of OC for a flat buyer?
- Home loan. Lenders often release the last instalment only after the OC. Without it you may need to fund the gap yourself.
- Under GST rules, a ready flat with an occupancy or completion certificate carries no GST, while a non-affordable under-construction flat carries 5% without input credit. See the GST portal.
- Permanent electricity and water connections usually require it.
- Legal safety. Occupying a building without an OC can invite penalties and trouble at resale or redevelopment.
- Resale value. Buyers and banks ask for the OC on any later sale.

What is a part occupancy certificate?
A part OC is issued for only a portion of a project, for instance one wing or a set of floors. It lets those residents move in while work continues elsewhere. Before relying on one, ask three things: which floors and wings it covers, whether the common areas and lifts are included, and what remains pending for the full OC.
For multi-tower projects such as One Uttam, which has four 18-storey towers, a staged approach is common, so the question of what the OC covers is a fair one to ask the sales team at the time of booking.
What should your Agreement for Sale say about the OC?
- That possession will be offered only after the occupancy certificate is received, or that a copy will be given at possession.
- The expected date of the OC, linked to the possession date registered on MahaRERA.
- What happens if the OC is delayed, including interest or compensation under RERA.
- A commitment to share the OC and related approvals with the society once it is formed.
These clauses cost nothing to ask for, and a transparent developer will not object.
How to check OC in Mumbai before you buy?
- Ask the developer or society for a copy and read the date, building name and floors covered.
- Check that the details match the sanctioned plan and the MahaRERA record on the MahaRERA portal.
- For a resale flat, ask the society for its OC and conveyance papers.
- Have your advocate check the record with the municipal office if anything looks incomplete.
If you are buying under construction, the OC will come later. Make sure the Agreement for Sale states the developer’s obligation to deliver possession with the OC, and read about the wider trade-offs in our guide to under-construction flats in Chembur.
Common mistakes to avoid
- Treating the completion of construction as the same thing as having an OC.
- Accepting possession without receiving a copy of the OC.
- Assuming a part OC covers every floor of the project.
- Forgetting that the final loan instalment may depend on the OC.
