How to Verify DTCP and CMDA Approval Before Buying a Plot in Chennai

Buying a plot is a big decision, and your first question should not be about price. It should be whether the layout is legally approved. In Chennai, approval can affect whether you can get a building plan sanctioned, a bank loan and a smooth resale later. Here is how to check it, step by step, before you pay any advance.
Why layout approval matters

An approved layout has planned roads, reserved open space and plot boundaries that match the sanctioned plan. An unapproved plot may look cheaper, but you can face problems getting a building permit, electricity and water connections, or a home loan.

DTCP or CMDA: which one applies?

Layouts inside the Chennai Metropolitan Area are approved by CMDA, while layouts in other planning areas of Tamil Nadu are approved by DTCP. Ask the seller which authority approved the layout, and note down the approval number and date. This number is what you will verify.

Step-by-step verification
  • Ask for the approved layout plan and match your plot number, dimensions and road width with it.
  • Check the approval number with the official CMDA or DTCP website, or at the local office.
  • Confirm RERA registration on the TNRERA portal where it applies, and note the RERA number.
  • Verify the patta, chitta and Field Measurement Book (FMB) sketch for the survey number.
  • Get an Encumbrance Certificate (EC), ideally covering the last 30 years, to confirm there are no pending dues or disputes.
  • Study the parent documents to trace ownership back to the original owner.
Red flags to watch for
  • The seller avoids sharing the approval number or layout plan.
  • Plot numbers in the brochure do not match the approved plan.
  • Roads or park areas are being sold as plots.
  • You are pressured to pay a large advance before seeing documents.
Get a lawyer to review the title

Even when everything looks fine, have an independent property lawyer review the title documents. The fee is small compared with the value of the plot, and it gives you peace of mind.
