TN RERA Check: How to Verify a Flat in Chennai Before You Buy

Key takeaways

Always check the registration number on the official Tamil Nadu RERA portal: rera.tn.gov.in.
Read the promoter, validity, status, layout plans and the declared completion date, not just the number.
Compare the number in the brochure or advert with the one on the portal.
For Brigade Altius, Brigade lists TN/29/Building/0020/2025; verify it yourself.

What RERA registration tells you

RERA is the Real Estate (Regulation and Development) Act. State regulators, including the Tamil Nadu Real Estate Regulatory Authority, keep a public record of registered projects, and the check applies to any of the Brigade projects in Chennai or elsewhere. For a buyer, the record is a free way to confirm that a project exists on paper as the builder describes it. Registration is not a guarantee of quality or of delivery, and it does not replace a lawyer's check of the title and the agreement, but a project that is not registered when it should be is a serious warning sign.

How to check TN RERA, step by step

Get the number first. Ask the builder or sales team for the project's registration number, and note the exact project and promoter names.
Open the official portal. Go to rera.tn.gov.in. Type the address yourself or use a bookmark, never a link from a message.
Find registered projects. Open the registered projects section and search by project name, promoter name or registration number.
Open the project record. Read the registration number, the validity period, the approval status and the promoter details.
Check what was declared. Look for the layout plans, the unit details and the project start and expected completion dates where the record shows them.
Match it to your documents. The number and the names in your booking form and agreement should match the portal exactly.

The portal's layout can change, so follow its on-screen guidance and, if you are unsure, ask the regulator or a lawyer.

A worked example: Brigade Altius

Brigade Group lists the TN RERA number TN/29/Building/0020/2025 for Brigade Altius, its project in Sholinganallur on OMR. We publish it for convenience, but please do not take our word for it: search the number on the portal, confirm the project name and promoter, and read the completion date that was declared. Brigade's project page does not state a possession date, so the RERA record is where you should look for the timeline.

Red flags to take seriously

No registration number in the brochure, the website or the booking form.
A number that does not appear on the portal, or that belongs to a different project or promoter.
A completion date in the sales pitch that differs from the one on the portal.
Pressure to pay a large booking amount before you have seen the registration and the agreement.
Payment requests to an account that does not match the promoter's name.

What to do next

Once the registration checks out, compare the project with your shortlist using our guide to apartments in Sholinganallur, work out what you can afford with our 3 BHK budget guide, test the commute with the OMR checklist, and ask for a written cost sheet. Have a lawyer read the agreement. If you have a question about a Brigade project, TSS Global can help you with the project's published details.

Look at the completion date declared on the project's RERA record and the date written in your agreement, and ask for the current construction stage in writing.
