Two planning authorities, one question
Chennai's plots are approved by one of two bodies. The Chennai Metropolitan Development Authority (CMDA) approves layouts inside the metropolitan planning area. The Directorate of Town and Country Planning (DTCP) approves layouts in the rest of Tamil Nadu, including much of Chengalpattu district. Both approvals mean the layout's roads, plot sizes and open-space reservation follow planning rules.
Why buyers care
Banks ask for the approval before sanctioning a plot or home loan, and building permission for your house depends on it. An unapproved layout can leave you with a plot you cannot easily finance, build on or sell.
Price and location
CMDA plots, such as our Tambaram and Kovilanchery layouts, usually cost more per sq.ft because they sit closer to the city with corporation services. DTCP plots in Guduvanchery, Chengalpattu and Thaiyur give more land for the money, along corridors where infrastructure is still arriving.
How to check
Ask for the approval letter and the approved layout plan with its number, and match your plot number and dimensions to the plan. For RERA-registered projects, the registration can be looked up on the Tamil Nadu RERA website.
