A plot in an unapproved layout cannot get a building permit, an electricity or water connection, or in most cases even be registered again, under Tamil Nadu’s Regularisation of Unapproved Layouts and Plots Rules, 2017. That single rule is why the approval number on a layout plan matters more than the brochure, the arch at the entrance or the promise of a nearby metro station.
Around Chennai, who approves a layout depends on where it is. Inside the Chennai Metropolitan Area, which now stretches well beyond the city into parts of Tiruvallur, Kancheepuram and Chengalpattu districts, it is the Chennai Metropolitan Development Authority (CMDA). Outside it, the Directorate of Town and Country Planning (DTCP) and its local offices approve layouts. Here is how to check a plot and what regularisation can and cannot fix.
What an approved layout looks like
An approved layout plan carries an approval number and date from CMDA or DTCP, and is drawn to show plot numbers and sizes, road widths, and land set aside as open space reserve (OSR) for parks and public use. In an approved layout, the roads and OSR are handed over to the local body by gift deed, so the panchayat or municipality takes over their upkeep.
Warning signs that a layout is not what it claims:
- The seller shows only a “panchayat approval” or a local body resolution. Panchayats do not approve layouts on their own.
- The approval number on the brochure does not match the one on the sale deed draft, or no number is given.
- The plot you are offered sits on land marked as a park or OSR in the approved plan.
- The layout is on land classified as a water body, poramboke or a road alignment.
How to check a layout yourself
- Get the approval copy. Ask the seller for the approved layout plan and the approval letter with its number and date, and photograph both.
- Verify with the planning authority. CMDA’s website lets applicants track planning permission applications, and the state’s single window planning permission portal handles approvals for CMDA, DTCP, town panchayats and municipalities. For older approvals, a written request at the CMDA office in Koyambedu or the local DTCP office is the reliable route.
- Match the land records. Check the survey number on the layout against patta, chitta and the A-register on the Revenue Department’s e-services site, and confirm the land is not classified as government or water body land.
- Visit the local body. Ask the panchayat or municipality whether the layout’s roads and OSR were gifted to it. If they were, that is a strong sign the approval is genuine.
- Read the encumbrance certificate for the plot to see the chain of sales.
Regularising an unapproved plot
If you already own a plot in an unapproved layout, the 2017 rules offer a way to regularise it, with strict limits. Only plots and layouts with a registered sale or title deed on or before 20 October 2016 are eligible. An agreement of sale or power of attorney does not count as proof.
The rules exclude land in water bodies, government poramboke, OSR or park areas, road and rail alignments, and high-tension line corridors, and plots that encroach on public roads. The access road must be at least 4.8 metres wide in corporations and municipalities, and 3.6 metres in town and village panchayats.
The charges, per square metre of plot area, as set in the rules:
| Area | Regularisation charge | Development charge |
|---|---|---|
| City municipal corporation | ₹100 | ₹600 |
| Municipality | ₹60 | ₹250 to ₹350 by grade |
| Town panchayat | ₹30 | ₹150 |
| Village panchayat | ₹30 | ₹100 |
There is also a scrutiny fee of ₹500 per plot, and an OSR charge. For a whole layout, the OSR charge is worked out on 10 per cent of the layout area at guideline value, less any open space already provided. Payment is due within 30 days of the demand notice, with interest at 6 per cent if late, and the application is rejected if the money is not paid within 90 days. These rates are from the original 2017 rules; amendments have followed, including one in 2019 listed on the DTCP’s orders page, so check the current rates and the application window with CMDA or DTCP before you apply.
What regularisation does not do
Regularisation makes a plot legal for residential use. It does not fix a bad title, settle a boundary dispute with a neighbour or move a plot off a water body. Layouts where more than two-thirds of plots were sold before the cut-off may be regularised as they are. Where fewer were sold, the rules require the layout to conform more closely to development regulations, and unsold plots can be reorganised to provide open space. A buyer in such a layout may find the final plan differs from the brochure.
