When you are buying an under-construction property, checking the project location, price, floor plan and amenities is not enough. You should also know whether the developer has received the required permission to start construction. One of the most important documents to check is the Commencement Certificate, commonly known as a CC.
Under Section 2(m) of the Real Estate (Regulation and Development) Act, 2016, a Commencement Certificate means a certificate, building permit, or construction permit issued by the competent authority that authorizes the developer to begin development work in accordance with the sanctioned plan. In simple words, a CC confirms that the concerned municipal corporation, development authority, or planning authority has permitted construction to begin.
For a homebuyer, this document is important because it helps confirm whether the developer’s construction has the required approvals.
What Does a Commencement Certificate Actually Verify?
A valid CC demonstrates that the competent planning or municipal authority has permitted construction to begin on the basis of approvals applicable to the project. It should not, however, be treated as a substitute for every other due-diligence document.
1. Permission to Begin Construction
The primary purpose of a Commencement Certificate is to confirm that the developer may commence development in accordance with the sanctioned permissions and subject to conditions imposed by the competent authority. Construction beyond the scope mentioned in the certificate may require additional or revised approvals.
2. Sanctioned Building Plans
Before development begins, projects generally require sanctioned plans dealing with matters such as the building layout, permissible development, planning requirements and other specifications governed by applicable local laws.
RERA separately requires the promoter to submit the sanctioned plan, layout plan and project specifications when seeking registration.
3. Statutory Approvals and Conditions
Depending on the project’s location, size and nature, approvals or NOCs concerning fire safety, environmental requirements, aviation restrictions, utilities or other civic matters may also apply.
Buyers should therefore examine the complete set of approvals disclosed for the project rather than assuming that possession of a CC automatically confirms every possible NOC.
4. Land Title Must Be Checked Separately
A common misconception is that a Commencement Certificate proves that the project’s land title is completely free from disputes.
RERA treats these matters separately. Under Section 4, the promoter must declare its legal title to the project land and disclose encumbrances, if any. Buyers should consequently review the project’s title-related disclosures and legal documentation in addition to checking the CC.
Partial and Stage-Wise Commencement Certificates
Another detail homebuyers frequently overlook is that a CC may not necessarily authorise construction of the entire proposed building at once. Authorities may issue permissions in stages. This is particularly important in Maharashtra, where MahaRERA has specifically recognised that commencement approvals can be granted only up to the plinth, zero-FSI stage or a particular floor level.
MahaRERA consequently requires promoters to disclose the exact extent of the commencement permission through its prescribed declaration and update the information when further approvals are obtained. For buyers, this means that merely seeing the words “Commencement Certificate” is not enough.
If you are considering an apartment on the 15th floor, for example, examine whether the current approval covers construction to that level. The sanctioned extent of construction should correspond with the unit and building being marketed.

How to Verify a Commencement Certificate Before Buying
A photocopy or PDF provided by a salesperson should be treated as a starting point, not the end of your due diligence.
Follow these checks before proceeding:
Step 1: Obtain the RERA registration number.
For a project required to be registered under RERA, identify its official registration number and ensure it corresponds to the exact project or phase you are considering.
Step 2: Visit the official State RERA portal.
Search through the regulatory authority’s official website, for example, MahaRERA in Maharashtra or the corresponding RERA authority in another state.
Step 3: Search for the registered project.
Use the project name, promoter details, or registration number to open the regulator’s project record.
Step 4: Review the approvals and uploaded documents.
Look for the Commencement Certificate, sanctioned plans, approval disclosures and, where applicable, declarations showing how much construction has actually been authorised.
In Maharashtra, verification has received particular regulatory attention. Following cases involving allegedly fraudulent certificates, MahaRERA introduced a system for comparing commencement certificates submitted by promoters with certificates received from competent authorities before processing registration applications.
Step 5: Compare the certificate with what you are being offered.
Check the project name, survey or plot details, building or wing, approved construction stage, floors covered, issuing authority, conditions and validity information appearing on the document.
Any unexplained mismatch deserves further investigation before money changes hands.

Why the CC Matters to a Homebuyer
A Commencement Certificate is not a procedural formality buried in a developer’s paperwork. It tells a buyer whether the competent authority has permitted construction to proceed, and, crucially, how far that permission extends.
At Openplot, we believe property decisions should begin with verifiable information. Before purchasing an under-construction home, check the project’s RERA registration, Commencement Certificate, sanctioned plans, title and encumbrance disclosures, and subsequent approvals independently.
A few minutes spent verifying official records can reveal details that a brochure, site visit, or sales presentation may never show.
