by When buying a completed apartment in Coimbatore, buyers often check the sale deed, encumbrance certificate, undivided share and property tax history. One important document is frequently overlooked: the occupancy certificate or the applicable completion certificate issued by the competent authority. For more information, see properties in Coimbatore.
An occupancy certificate is not the same as a building plan approval. Plan approval permits construction according to sanctioned drawings. An occupancy certificate, or an equivalent certificate recognised under local rules, relates to whether the completed building can be occupied. Under the Real Estate (Regulation and Development) Act, 2016, an occupancy certificate is issued by the competent authority and permits occupation of a building with civic infrastructure such as water, sanitation and electricity.

This guide explains how to check an occupancy certificate for flat in Coimbatore before signing an agreement, paying a substantial advance or proceeding with registration.
Why the occupancy certificate matters
An apartment may have an approved layout and building plan but still have unresolved completion or compliance issues. The occupancy certificate process is intended to connect the approved plan with the building that was actually constructed.
For a buyer, the document can help establish that:
- the relevant authority has considered the completed building for occupation;
- the building is linked to a sanctioned plan and completion documentation;
- essential services and common facilities have been addressed as required by the applicable rules; and
- the promoter has completed an important part of the handover process.
Tamil Nadu’s Combined Development and Building Rules state that a building should not be used, or possession given for occupation, before obtaining the completion certificate or occupancy certificate, as applicable. The rules also require the promoter to make relevant title documents, approved plans and certificates issued by the competent authority available to prospective purchasers. ([tnurbantree.tn.gov.in](https://www.tnurbantree.tn.gov.in/wp-content/uploads/sites/54/2019/08/Tamil-Nadu-Combined-Development-and-Building-Rules-2019_Gazette_43_Ex_III_1a_04.02.2019.pdf?utm_source=openai))
Occupancy certificate versus building plan approval
| Document | What it generally addresses | Why a buyer should check it |
|---|---|---|
| Building plan approval | Permission to construct according to approved drawings and conditions | Helps compare the sanctioned proposal with the completed structure |
| Completion certificate or completion report | Confirmation that construction has been completed, usually with professional and owner declarations | May form part of the authority’s process before occupancy approval |
| Occupancy certificate | Permission or certification relating to occupation of the completed building | Important for possession, use and final compliance due diligence |
| RERA project records | Project-level disclosures, approvals, progress and promoter information where RERA applies | Provides another source for comparing the promoter’s claims and documents |
The names and document sequence can vary depending on the local authority, building type, project stage and applicable rules. Do not assume that a document called “completion certificate”, “building completion certificate” or “occupation approval” has the same legal effect in every case. Ask the issuing authority or a property lawyer to confirm what the document means for the specific property. For more information, see sell property with Kanish Realty.
Step-by-step: how to check an occupancy certificate for a flat in Coimbatore
1. Identify the competent authority
First, identify which authority approved the building. A flat within Coimbatore City Municipal Corporation limits may involve the Corporation’s town-planning and building-permission systems. A property outside the Corporation may fall under a municipality, town panchayat, village panchayat or another planning authority. For more information, see Kanish Realty listings.
Do not rely only on the project brochure or the seller’s verbal explanation. Match the property address, survey details, ward or local-body details and approval reference shown in the documents.
Coimbatore Corporation publishes information on its online plan-approval process, while Tamil Nadu’s urban local-body citizen portal provides building-planning services and certificate-related search functions for participating local bodies. These portals and procedures may change, so use them as an initial reference and confirm the final document with the relevant authority. ([ccmc.gov.in](https://ccmc.gov.in/index.php/createpage/online-plan-approval?utm_source=openai))
2. Ask for the complete document, not a screenshot
Request a readable copy of the occupancy certificate or applicable completion certificate. A WhatsApp image showing only the first page is not enough.
Check whether the copy identifies:
- the name and address of the project;
- survey number, door number, plot number or other identifying particulars;
- the promoter, owner or applicant;
- the approval or application reference number;
- the date of issue;
- the issuing authority and authorised signatory;
- the number of floors, blocks or units covered; and
- any conditions, exclusions or remarks.
If the certificate covers only one block or phase, do not assume that it covers the entire development. Compare the certificate with the exact block and flat being offered to you.
3. Compare it with the sanctioned plan
Review the approved plan and the completed building together. Look for material differences such as:
- an additional floor or wing;
- conversion of parking or open space into a dwelling or commercial unit;
- changes to the number or size of flats;
- enclosure of balconies or common areas;
- relocation of staircases, lifts or fire-safety features; and
- changes in access roads, setbacks or utility areas.
A certificate does not automatically resolve every title, construction-quality or maintenance issue. Conversely, a building that appears occupied does not prove that all approvals are complete. If you find a mismatch, ask for the revised approval, regularisation record or written clarification from the competent authority before proceeding.
4. Check the project’s RERA disclosures where applicable
For a project covered by RERA, compare the promoter’s project records with the documents supplied to you. RERA requires the promoter to obtain the completion certificate or occupancy certificate, as applicable, from the relevant competent authority and make it available to allottees or the association of allottees. ([indiacode.nic.in](https://www.indiacode.nic.in/bitstream/123456789/18136/1/the_real_estate_%28regulation_and_development_%29_act%2C_2016_compressed.pdf?utm_source=openai))
Check whether the project name, phase, blocks, sanctioned plans and possession information are consistent. A RERA registration entry is useful due diligence, but it is not a substitute for examining the actual certificate and obtaining independent legal advice.
5. Verify the certificate with the issuing authority
Where the document is important to your decision, seek confirmation from the relevant local authority. Verification may involve an online search, an application-status record, inspection of an original document or a written response from the department.
Take the following information when making an enquiry:
- project and promoter name;
- full property address;
- survey and subdivision details;
- building-plan approval number;
- occupancy or completion certificate number and date; and
- the exact block, floor and flat number.
Do not treat a property-tax assessment, electricity connection, water connection or association maintenance receipt as proof of an occupancy certificate. These may show that services or occupation exist, but they do not replace confirmation from the competent authority.
Documents to check alongside the occupancy certificate
Occupancy due diligence should be part of a wider apartment document review. Also request and compare:
- parent title deeds and the current seller’s registered sale deed;
- encumbrance certificate for the relevant period;
- approved layout and building plans;
- RERA registration and project disclosures, where applicable;
- completion documents and structural or fire-related certificates, where applicable;
- property-tax receipts and current dues;
- association formation and handover records;
- maintenance and utility payment records;
- parking allocation documents; and
- the draft sale agreement and proposed sale deed.

Red flags that need clarification
Pause the transaction and obtain professional advice if:
- the seller says the certificate will be obtained after registration;
- the certificate covers a different block, phase or survey number;
- the document has no reference number, date or issuing authority;
- the completed building visibly differs from the approved plan;
- the promoter provides only a brochure, possession letter or association letter;
- the project has multiple phases but the documents do not identify yours; or
- you are pressured to pay a non-refundable advance before document verification.
A missing document is not always proof that a property is unlawful. Older buildings, independent developments and properties under different local authorities may follow different documentation practices. However, uncertainty should be resolved before you commit money, not after registration.
What should be written into the sale agreement?
If the seller or promoter says that an approval is pending, the agreement should clearly record the document involved, the responsible party, the expected action, the buyer’s rights if it is not produced and how any outstanding compliance issue affects possession or registration.
Do not rely on a general clause stating that the property is sold “as is where is” without understanding its effect. A property lawyer should review the agreement, especially where the certificate is missing, conditional or inconsistent with the sanctioned plan.
