If a builder in Trichy is selling flats and can’t give you a RERA number on request, that alone should slow you down. RERA registration isn’t a formality builders add for marketing. It’s a legal requirement, and skipping the check is one of the most common mistakes first-time buyers make in Tamil Nadu.
This guide walks through how to verify a project’s RERA status on the official Tamil Nadu portal, what the registration actually covers, which documents to check alongside it, and which red flags mean you should ask harder questions before booking.
Manoo Housing Promoters is a TNRERA-registered developer based in Trichy, and this guide reflects the same verification process we expect any buyer to run on our own projects before booking.
The Real Estate (Regulation and Development) Act, 2016 set up state-level authorities to regulate builders and protect buyers. In Tamil Nadu, that authority is TNRERA (Tamil Nadu Real Estate Regulatory Authority), formed in 2017. TNRERA also covers the Andaman and Nicobar Islands, since that territory has no regulator of its own.
Under the Act, any residential or commercial project built on more than 500 square metres of land, or with more than 8 units, must be registered with TNRERA before the builder can advertise, market, or sell a single unit. That applies to apartment complexes, gated communities, and plotted layouts alike. A project this size in Trichy, whether it’s in Thillai Nagar, Srirangam, Karumandapam, or Thuvakudi, cannot legally be booked without a registration number.
Registration forces the builder to disclose the sanctioned plan, the promoter’s track record, the project timeline, and the bank account where your payments are held. It also caps how much money a builder can collect before you sign a registered agreement for sale: no more than 10% of the total cost.
Step 1: Go to the official portal
Visit rera.tn.gov.in directly. Don’t rely on a link a broker or salesperson sends you. Type the URL yourself or search for “TNRERA” and confirm it’s a .gov.in domain.
Step 2: Search by project or promoter name
Use the quick search on the homepage and enter the project name or the promoter’s (builder’s) name. If the builder gave you a specific RERA registration number, search that directly for the fastest match.
Step 3: Confirm the registration is active
Open the project listing and check the registration number, the promoter’s name, the approval details, and the proposed completion date. Match every one of these against what the builder told you. A mismatch in the promoter name or the completion date is worth asking about directly.
Step 4: Cross-check the promoter’s other projects
TNRERA listings show a promoter’s registration history. If you’re buying from a builder with several projects in Trichy, look at whether their earlier projects were completed on the timeline they registered, or whether they’ve filed extensions repeatedly.
Step 5: If nothing comes up, ask why
If a search for the project or the builder returns no result, ask the builder for the exact registration number and search that directly. If they can’t produce one, or the number doesn’t match any TNRERA record, treat that as a serious warning sign, not a paperwork delay.
A valid RERA registration confirms the project is legally allowed to sell. It doesn’t confirm everything else about the deal, so check these alongside it:
None of these replace a lawyer’s review before you sign anything, but checking them yourself first means you walk into that review already knowing what to ask.
RERA awareness tends to be higher in Chennai, where buyers have seen more media coverage of registration checks. In Trichy and other tier 2 markets, fewer buyers actually open the TNRERA portal before booking, which is exactly why a handful of unregistered or misrepresented projects can operate for longer without scrutiny. As the city’s residential market grows across localities like Karumandapam, Srirangam, and Thuvakudi, the number of new launches is rising too, which makes the five-minute check more relevant, not less. The check itself costs nothing. Skipping it can cost years in delayed possession or a legal dispute over a plan that was never approved.
A handful of situations don’t require RERA registration: projects under 500 square metres or 8 units, and homes that received their Occupancy Certificate before RERA came into force in 2017. If a builder claims an exemption, ask for documentation proving which exemption applies rather than taking it on trust.
Outside those cases, an unregistered project being actively marketed is operating outside the law. Booking into one removes the legal protections RERA gives you, including the right to compensation for delayed possession and the ability to file a complaint with TNRERA if the builder defaults.
RERA registration doesn’t guarantee a project will go smoothly, but its absence is a clear signal to walk away or ask harder questions. Before you pay a booking amount on any apartment in Trichy, search the project on rera.tn.gov.in yourself. It costs nothing and takes less time than a single site visit. If you’re looking at projects from Manoo Housing Promoters, our registration details are available on request and on the TNRERA portal under our promoter name, so you can run this exact check before you commit.
Only for projects over 500 square metres or with more than 8 units. Smaller developments and homes with pre-2017 Occupancy Certificates are exempt.
Yes. The search is public and free, with no login required.
Yes, the same search applies. Fully completed homes that received their Occupancy Certificate before RERA came into force may not appear in the database.
Ask for the exact registration number in writing. If none exists or it doesn’t match, treat the project as unregistered and get legal advice before paying anything.
You can file a complaint directly with TNRERA, which has the authority to order compensation or penalties against the promoter.
