Inside the Chennai Metropolitan Area, layouts and buildings are approved by CMDA (the Chennai Metropolitan Development Authority), not DTCP. The area covers Chennai district and parts of Thiruvallur, Kanchipuram and Chengalpattu.

Why the CMDA approval matters

Whether you're looking along GST Road, OMR or the western side towards Avadi and Poonamallee, the approval tells you the layout fits the Chennai master plan. That protects you from nasty surprises later, like a road-widening line or a zoning change running through your plot.

How much you can build

How many floors you can put up depends on the road width and the plot size under the building rules. Ask for the permitted floor area before you buy if you're planning to build for rent.

What we check

We look up the planning permission number on the CMDA portal, go through a 30-year Encumbrance Certificate, and make sure the Patta is up to date on the e-Services site.

It depends on the road width and plot size under the Tamil Nadu Combined Development and Building Rules. Check the permitted floor area for that specific plot before you buy.

Generally yes — banks prefer approved layouts with a clean title. They'll still run their own legal and technical checks before sanctioning.
