RERA in Tamil Nadu — Registration Lookup, Complaints & 2026

RERA Tamil Nadu: TNRERA is the Tamil Nadu Real Estate Regulatory Authority in Chennai. It charges ₹1,000 per complaint and uniquely classifies projects as "Building" or "Layout". Verify Tamil Nadu projects on rera.tn.gov.in and separately confirm CMDA or DTCP layout approval.

What is Tamil Nadu RERA

TNRERA — the Tamil Nadu Real Estate Regulatory Authority — was constituted on 22 June 2017 and is headquartered in Chennai. TNRERA covers the entire state including Chennai, Coimbatore, Madurai, and the rapidly growing OMR / GST Road / Avadi residential belts.

Tamil Nadu runs an unusual dual classification: TNRERA distinguishes between "Building" registrations (apartments, flats) and "Layout" registrations (plotted developments). Each has slightly different documentation requirements. CMDA / DTCP layout approvals must be verified independently.

Tamil Nadu RERA portal & verification steps

The official portal is rera.tn.gov.in ↗. Six-step verification:

Visit the portal and click "Registered Projects".
Search by project name (partial match works) or paste the full registration number.
Verify registration date, validity (proposed completion), promoter PAN, sanctioned plan PDF, Form-3 CA certificate.
Click "Quarterly Updates" — confirm the most recent QPR is within the last 90 days. Older = red flag.
Check "Complaints" tab for any pending or disposed complaints against the project.
Cross-verify the promoter on the relevant sub-registrar portal for title-deed chain.

Always verify on the official .gov.in domain — never trust a builder microsite, broker WhatsApp forward, or any third-party "RERA-approved" claim.

How to file a RERA complaint in Tamil Nadu

Filing fee: ₹1,000 per complaint.

Register on the TNRERA portal as a complainant. KYC with Aadhaar + PAN.
Pay the filing fee through the portal payment gateway.
Upload the complaint with allotment letter, sale agreement, all payment receipts, and the builder's possession commitment letter.
The Authority issues notice to the promoter — typically within 30–60 days.
Hearings scheduled at the TNRERA office or via video conference.
Order issued — statutory target 60 days, in practice longer.

Notable Tamil Nadu RERA cases & enforcement

TNRERA has issued multiple Section-18 refund orders on stalled OMR (Old Mahabalipuram Road) and GST Road projects (2021–2024).
A wave of cease-and-desist notices was issued in 2022–2023 against promoters advertising plotted layouts in suburban Chennai without TNRERA layout registration.
TNRERA flagged several Coimbatore developers in 2024 for QPR non-filing — names published on TNRERA defaulter bulletin.

Tamil Nadu RERA registration number format

The TNRERA registration number follows the pattern TN/{district}/Building or Layout/{serial}/{year}. Example: TN/01/Building/0123/2022.

Always paste the FULL alphanumeric string into the portal search box — partial matches frequently fail. Treat any project listed only with a "RERA approved" tag and no actual number as unregistered until proven otherwise.

Tamil Nadu-specific quirks every buyer must know

TNRERA splits registrations into "Building" and "Layout" — verify the correct registration type for your project.
TNRERA does NOT substitute for CMDA (Chennai) or DTCP (Tamil Nadu) layout approval — buyers MUST verify both.
Tamil Nadu has a vibrant plotted-layout market — TNRERA actively registers and enforces on layouts above 500 sqm.
Patta and chitta records (state revenue documents) are critical title evidence in Tamil Nadu.
TNRERA disposal is slower than MahaRERA — budget 6–14 months for complaint resolution.
