What Is a Commencement Certificate? Why Buyers Must Check It
Before a builder can start construction on a project, the law requires one key approval: the commencement certificate. If a builder starts work without it, the project is illegal and your money is at risk. This guide explains what a commencement certificate is, why it matters to a buyer, and how to check it before you book a home.
What a commencement certificate means
A commencement certificate, often called a CC, is a document issued by the local authority or municipal body that permits a developer to begin construction on a project. It is granted after the authority approves the building plan and confirms that the project meets the local building rules, land use and safety norms. Only after receiving the commencement certificate can the builder legally start work above the foundation.
Why it matters to a buyer
The commencement certificate is proof that the project has the basic legal green light to be built. If you book a flat in a project that lacks a commencement certificate, you are buying into an illegal or stalled construction. The authority can halt the work, and you may face delays or loss. A valid commencement certificate lowers this risk. It is one of the first documents to ask for before you pay any booking amount.

Commencement certificate versus other approvals
Buyers often confuse the different certificates in a project's life. The commencement certificate comes at the start, before construction. The occupancy certificate and completion certificate come at the end, when the building is ready and fit to live in. Each marks a different stage. Read our guide on the occupancy and completion certificates for the end-stage approvals.
| Certificate | Stage | What it confirms |
|---|---|---|
| Commencement certificate | Before construction | Builder can legally start work |
| Occupancy certificate | After construction | Building is fit to occupy |
| Completion certificate | After construction | Built as per approved plan |
How to check the commencement certificate
- Ask the builder. Request a copy of the commencement certificate for the specific project and tower.
- Check the RERA page. Registered projects list their approvals on the state RERA site. Verify it there. See our guide on how to check RERA registration.
- Match the details. Confirm the project name, land details and the sanctioned floors match the certificate.
- Check validity. A commencement certificate can lapse if work does not start in time. Make sure it is current.
What if a project lacks it
If a builder is selling flats in a project without a commencement certificate, treat it as a red flag. Construction without this approval can be stopped or penalised by the authority. Do not pay a large amount until the certificate is in place. A trustworthy builder will show it readily. Verify the builder's track record with our guide on how to verify a builder.
Frequently asked questions
What is a commencement certificate?
It is a document from the local authority that permits a developer to begin construction on a project after the building plan and land use are approved.
Why is a commencement certificate important?
It proves the project has legal permission to be built. Without it, construction is illegal and can be halted, putting your money at risk.
Who issues the commencement certificate?
The local municipal body or development authority issues it after approving the building plan and confirming compliance with building rules.
What is the difference between a commencement and an occupancy certificate?
The commencement certificate is issued before construction to allow work to start. The occupancy certificate is issued after construction to confirm the building is fit to occupy.
Can a builder start construction without a commencement certificate?
No. Starting construction without it is illegal, and the authority can stop the work or impose penalties.
How do I check if a project has a commencement certificate?
Ask the builder for a copy and verify it on the state RERA website, where registered projects list their approvals.
Does a commencement certificate expire?
It can lapse if construction does not begin within the time set by the authority. Confirm the certificate is current before you book.
Is a commencement certificate the same as a building plan approval?
They are linked but different. The building plan approval sanctions the design, and the commencement certificate then permits actual construction to begin.
Should I pay a booking amount before the commencement certificate?
It is safer not to pay a large amount until the certificate is in place. Treat its absence as a warning sign.
Is a commencement certificate needed for a plot?
For building on a plot, you need the relevant construction approvals from the local authority, which include permission to start work. Rules vary by area.
Does a partial commencement certificate exist?
Yes. Large projects may get a commencement certificate for certain towers or up to a certain height first, and then further approvals for more floors.
What happens if I already bought in a project without one?
Push the builder to obtain it and check the RERA status. Take legal advice, since construction without approval carries real risk of delay or demolition.
Is the commencement certificate part of RERA documents?
Yes. For a RERA-registered project, the approvals, including the commencement certificate, are listed on the project's RERA page.
Can construction be stopped after the certificate is issued?
Yes, if the builder breaks the approved plan or other rules. The certificate permits a start, but the builder must keep following the sanctioned plan.
The commencement certificate is the first legal check on any new project. Ask for it, verify it on RERA, and never pay big before it is in place. Explore new launches with verified approvals on our site.
