NA Conversion in Tamil Nadu: The Approvals Question

Start from where the land sits. Inside planning areas the master plan already zones the ground, and a use the plan permits is a different project from a use needing reclassification through the planning machinery. The first document to read is not a conversion form; it is the plan's designation for the survey number.

Layouts are where TN's discipline bites hardest. A field cut into plots becomes sellable house sites only through DTCP or CMDA approval, roads, open space and all, and the state has spent years squeezing the unapproved-layout market precisely because buyers kept paying house-site prices for paper subdivisions. An approval number you can check is the difference between a plot and a promise.

The revenue side follows rather than leads. The classification on the record, the patta after any subdivision, the assessment after the change of use, all of it should catch up with what the approvals authorised, and a file where the planning stack and the revenue record tell the same story is a file a bank reads quickly. Processes and fee bases here have shifted over the years; verify the current requirements for your district before money moves on an assumption.

Plan first, approvals second, record last.

The approvals path

Each layer authorises something specific. None substitutes for another.

TN conversion projects derail at four points.

The spread between approved and unapproved plot pricing is the entire cost and risk of this stack, and Tamil Nadu's market prices it brutally: approved sites carry premiums precisely because the approvals are hard to retrofit.
