Tamil Nadu's TNRERA oversees a market heavily concentrated in Chennai — including OMR, ECR, and the Porur-Poonamallee corridor — with meaningful activity in Coimbatore, Madurai, and Tiruchirappalli. Chennai's project mix skews toward mid- and premium apartments, where delivery delays have historically been a concern during monsoon-affected construction cycles. TNRERA publishes project data online, but enforcement action and complaint resolution run slower than MahaRERA or GujRERA, which shows up in the Legal Risk dimension of trust scores. Buyers in Tamil Nadu should pay particular attention to flood-zone land titles in coastal Chennai and to phase-based registrations where only earlier phases were delivered.

Chennai (including suburban Kanchipuram and Chengalpattu) dominates, followed by Coimbatore, Madurai, and Tiruchirappalli.
Look for the project's registration expiry date and renewal history on its RERAScore page — lapsed or expired registrations are called out directly in the project status and registration score.
