Tamil Nadu RERA Complaint Procedure — TNRERA Guide for Chennai and Tamil Nadu Allottees

Last updated 2026-05-30

Tamil Nadu RERA (TNRERA) has historically been a low-volume but increasingly active authority. Project disputes in Tamil Nadu cluster around three centres — Chennai (apartments, OMR / GST road, Adyar), Coimbatore (mid-segment apartments) and Madurai (mostly plots and small commercial). TNRERA's procedural framework follows the central template with a few state-specific differences — the lowest registration threshold among major states, a streamlined complaint form, and an interest rate aligned with most other states. This guide walks through the legal framework, portal usage, fee structure, and the issues that recur in Chennai apartment-development orders.

The legal framework — Act + Tamil Nadu Rules + Regulations

TNRERA's operating documents:

  1. Real Estate (Regulation and Development) Act, 2016 — central.
  2. Tamil Nadu Real Estate (Regulation and Development) Rules, 2017 — interest rate at SBI's highest MCLR + 2% (Rule 16); registration fees; complaint procedure scaffolding.
  3. TNRERA Regulations — complaint form and fees.

Tamil Nadu-specific differences:

  • Stamp duty interaction — Tamil Nadu has a 7% sale-deed stamp duty (no women's concession), the highest among major states, which influences how disputes over consideration value play out.
  • Court fee on TNRERA complaints (in addition to the registration's complaint fee) — Tamil Nadu uniquely requires a Court Fee Act ad-valorem stamp on certain complaints. Most complaints in 2024-25 have been filed with the registration fee only; the court-fee question is unsettled but practitioners are advised to keep an additional ₹50-100 ad-valorem stamp.
  • The TNRERA online portal is integrated with the Tamil Nadu e-Sevai single-window system in some flows.

TNRERA portal walkthrough and Form 'M'

Portal: rera.tn.gov.in.

  1. User registration — Aadhaar OTP login.
  2. 'File New Complaint'.
  3. Project selection — search by Project ID (format: TN/01/Building/Apt/2018-2024/00xx) or by promoter name.
  4. Form M fields:
  • Complainant particulars including Aadhaar.
  • Project and unit details.
  • Brief facts (1,500 characters).
  • Reliefs.
  1. Documents — agreement for sale, payment proofs, allotment letter, builder correspondence.
  2. Fee — ₹1,000 per complaint.
  3. Complaint number generated.

Hearing volume — TNRERA averages fewer hearings per month than MahaRERA or UP RERA. First hearings typically come within 60-90 days, slightly slower than MahaRERA. Order timelines run 9-12 months on average.

Chennai-specific recurring issues:

  • OMR / Old Mahabalipuram Road — multiple projects affected by Sholinganallur-Navalur corridor approval issues; recurring force-majeure pleas around CMDA (Chennai Metropolitan Development Authority) approval delays.
  • Adyar / Mylapore high-end apartments — disputes typically about quality of finish and post-OC defects rather than possession delays.
  • Coastal Regulation Zone (CRZ) — relevant for projects in ECR (East Coast Road) and along coastal Tamil Nadu. CRZ violations trigger Section 14 defaults; TNRERA orders have referenced the Wetlands Rules and CRZ Notification 2019 where projects exceeded their approved coastal setback.

Frequently asked questions

What is TNRERA's interest rate under Section 18?+

TNRERA applies SBI highest MCLR + 2% per annum (Rule 16 of the Tamil Nadu RERA Rules 2017). For orders in 2026, approximately 10.85–11.10% p.a.

Is the TNRERA portal in Tamil?+

Yes — TNRERA's portal supports both English and Tamil interface. Form M can be filled in either language. Order copies are issued in English by default; Tamil translations on request, with a processing time of 7-14 days.

Where do TNRERA appeals go?+

To the Tamil Nadu Real Estate Appellate Tribunal (TN REAT) at Chennai under Section 44 within 60 days. Appeal fee ₹1,000; promoter-appellants against money awards must pre-deposit 30% under Section 43(5).

Are CRZ-violation projects under TNRERA jurisdiction?+

Yes — TNRERA exercises jurisdiction over registered projects even where the project subsequently faces CRZ enforcement issues. The Authority has ordered refund-with-interest under Section 18 in several cases where the project was later found to be in CRZ violation and could not deliver possession lawfully. The fact that the CRZ violation predated RERA registration is relevant to apportionment of liability but not to the allottee's right to refund.
