How to Verify TNRERA Registration Before Buying an Apartment in Chennai

Tamil Nadu Real Estate Regulatory Authority (TNRERA) registration is one of the few property checks you can genuinely complete yourself, for free, in a few minutes — the registered-project database is public.

What TNRERA actually regulates

TNRERA operates under the Real Estate (Regulation and Development) Act, 2016, covering Tamil Nadu and the Andaman & Nicobar Islands. Its stated registration requirement applies to real estate projects and real estate agents — a project must register if it has more than 8 proposed apartments or the land area exceeds 500 square metres.

That threshold matters: a very small building genuinely can fall outside mandatory registration. Registration status alone isn't the whole verification — but for anything above that threshold, a missing registration number is a real gap you should ask about directly, not something to explain away.

How to actually search the registry

The official portal (rera.tn.gov.in) lets you search registered projects by:

• Project name
• Promoter (developer) name
• Registration number
• District
• Pincode

No login is required for this basic search. The same portal also maintains a separate registry of real estate agents — both currently registered and those whose registration has lapsed — so you can check whether the agent you're dealing with is actually authorised, not just the project itself.

What the registry actually tells you

Beyond confirming a project is registered at all, the portal's project record typically shows the promoter's other registered projects (past and ongoing) and any orders or penalties TNRERA has issued against that promoter. A promoter with an unusual pattern of withdrawn, rejected, or penalised projects is worth researching further before you commit — that information sits in the same public record, not hidden behind a paywall.

What to actually do before you buy

• Search the project by name and registration number — confirm they match what's on the promoter's own marketing material and sale agreement draft.
• Search the promoter's name separately to see their full project history, not just the one you're being shown.
• If you're dealing with an agent, verify their registration in the separate agent registry.
• If the project is below TNRERA's registration threshold, ask the promoter directly why — and get that answer in writing, not just verbally.

A registration number that checks out on the official portal is a real, verifiable fact. A registration number a broker reads out to you over a phone call is not — always confirm it yourself on the portal before you rely on it.
