TNRERA (Tamil Nadu Real Estate Regulatory Authority), formed under the RERA Act 2016, has registered over 4,200 projects statewide as of 2026. Any project with more than 8 units or 500 sqm of land must register. 2026 updates include a 70% escrow mandate, 10.5% per annum delay penalties, mandatory broker registration, and mandatory carpet-area disclosure from April 2026.
Quick answer: TNRERA remains the primary safeguard for Tamil Nadu homebuyers, with 2026 bringing tighter enforcement rather than new rights. Projects above 8 units or 500 sqm must register, keep 70% of buyer funds in an escrow account released only against certified construction milestones, and upload quarterly geo-tagged progress reports. Delay penalties now run at 10.5% per annum (SBI MCLR + 2%) on amounts paid, brokers must hold valid TNRERA registration or face fines up to ₹10,000/day, and from April 2026 builders must advertise carpet area rather than super built-up area. Buyers can verify any project's registration number at tnrera.in and file a complaint within 3 years of possession, with adjudication due within 60 days. Tamil Nadu's stamp duty and registration charges (7% + 4% for most sale deeds) apply on top of the purchase price.
What Is TNRERA?

As of 2026, TNRERA has registered over 4,200 projects across the state.

How to Verify a Project on TNRERA
Visit tnrera.in → Search Projects → Enter the project name or TNRERA registration number (format: TN/01/Building/XXXX/XXXX). Always verify before paying any booking amount. A registered project gives you legal recourse under RERA for delays, quality defects, and title issues.
TNRERA Complaint Process
If a builder delays possession or fails to deliver promised amenities, you can file a complaint on tnrera.in within 3 years of possession. The adjudicating officer must pass an order within 60 days. You can also appeal to the TNRERA Appellate Tribunal if unsatisfied with the ruling.
