Buying a home is probably the biggest financial decision you will make in your lifetime. In a city like Chennai, where new projects are coming up across OMR, Avadi, Tambaram, and beyond, the options can feel overwhelming.
Every builder you meet will have a polished pitch. A beautiful model flat. Promises of timely handover, world-class amenities, and a great location. It all sounds convincing in the room.
But how do you actually verify any of it?
That is where RERA comes in. It is not complicated, and you do not need a lawyer to understand it. What you do need is to know how to use it before you sign anything or pay a single rupee. If you are buying for the first time, here is everything else you should know before getting started.
RERA stands for Real Estate Regulation and Development Act. Introduced in 2017, it made it mandatory for builders to register every project publicly, declare timelines upfront, and be held accountable if they don't deliver.
In Tamil Nadu, this is handled by TNRERA. Think of it as a public scoreboard, every registered builder, agent, and project is listed and open for anyone to verify.
Head over to the official TNRERA portal at rera.tn.gov.in. You can search by the project name, builder name, or the RERA number printed on the brochure. No login or registration required.
A simple step-by-step guide showing how to check project registration on the Tamil Nadu RERA website.
Once you find the project, confirm:
Do not just read the number off the brochure and assume it is correct. Always search it yourself on the portal.
Builders are legally required to show you this document. Most buyers glance at it and move on. Here is what to actually look for.
Registration number: Verify this yourself on the portal. Do not rely on a PDF or screenshot from the builder. Takes 30 seconds.
Completion date: This is a legal commitment, not an estimate. If a builder registers March 2026 as the handover date and gives you possession in June 2027, you are entitled to compensation or a full refund with interest. This is why on-time delivery is one of the most critical factors to evaluate before choosing a builder.
Sanctioned plan: The number of floors, units, and amenities as officially approved. If what is being sold to you does not match what is on the certificate, that is a conversation you need to have before paying anything.
Registration validity: An expired registration is not a paperwork technicality. It means the project has lost its legal standing under RERA entirely.
Delays: If the builder misses the registered handover date, you can legally claim compensation or walk away with a full refund plus interest. This alone has saved buyers lakhs in projects that dragged on for years beyond the promised date.
Plan changes: That open-air amphitheatre in the brochure cannot be quietly converted into another block of flats without your written consent. Whatever is in the approved plan is what must be delivered.
Financial misuse: 70% of your payments must go into a dedicated escrow account that can only be used for that specific project. This prevents builders from using your money to fund a different site while your home sits half-built.
Resale flats: Older completed projects and resale transactions are largely outside RERA's scope.
Verbal promises: If it is not written in the agreement, it does not exist legally. Simple as that. This is exactly why what you check before signing a sale agreement matters just as much as RERA itself.
Land title issues: RERA does not verify whether the land is legally clear. Always get an independent lawyer to check the title deed.
One red flag is worth investigating. More than one, reconsider seriously.
Brokers are also required to be individually RERA registered. Verify them on the same portal under the Agents section. If they are not listed, they are operating outside the law and you have no formal recourse if things go wrong.
RERA will not make every builder perfect. But it gives you a real, accessible way to verify who you are dealing with before you commit your money.
If you are actively exploring properties in Chennai for sale, make sure RERA verification is the first thing on your checklist, not an afterthought.
Five minutes on the TNRERA portal is five minutes very well spent.
