To verify a DTCP approved layout in Tamil Nadu, get the layout approval number (often called the LP number) and year from the seller, check it against the official planning records on the state’s single window planning portal or at the approving office, and then confirm that your exact plot, the roads and the open space in that approval match what is on the ground and in the title documents. A brochure line saying “DTCP approved” proves nothing until you have done this match yourself. This guide walks through the checks that buyers around Coimbatore should complete before paying any advance.
Key takeaways
- Ask for the layout approval number, year and the approving office in writing before you pay an advance.
- Match the survey numbers, plot number, plot size and road widths in the approved plan with the patta, FMB sketch and the site itself.
- A panchayat resolution or “approval” is not DTCP or LPA layout approval.
- Layouts above the RERA thresholds should also appear on the TNRERA website with a registration number.
- Old unapproved plots may be regularised, but that is a different status from an approved layout.
Who approves layouts around Coimbatore
In Tamil Nadu, residential layouts are approved under the Tamil Nadu Town and Country Planning Act, 1971. Outside the Chennai Metropolitan Area, the Directorate of Town and Country Planning (DTCP) and the Local Planning Authorities (LPAs) that work under it are the approving bodies. Around the city, land inside the Coimbatore Local Planning Area is handled by the Coimbatore LPA, while areas outside it fall under the DTCP district and regional offices. Either way, the approval comes with a plan showing plot numbers, dimensions, roads and the Open Space Reservation (OSR). Applications for layout and building approvals are now filed through the Tamil Nadu Single Window Portal for Planning Permission (onlineppa.tn.gov.in).
If you are still comparing approval types, our explainer on DTCP vs RERA approval for plot buyers covers the difference in detail.
Step by step: verifying the approval
1. Collect the approval details
Ask the seller or promoter for a copy of the approved layout plan and the approval letter. Note the approval number, the year, the approving office and the survey numbers covered. Genuine promoters share these readily. Be wary if you only get a number printed on a hoarding.
2. Check the record with the authority
Look up the layout on the official planning portal or the DTCP website where approved layout details are published, or visit the approving office (the Coimbatore LPA or the DTCP district office) with the number. Portal menus change from time to time, so if you cannot find the search option, a written query to the office is the reliable route. What you want to confirm is simple: the approval exists, it covers the survey numbers the seller claims, and your plot number is part of the approved plan.
3. Match the plan with the ground
Take the approved plan to the site. Check that your plot’s dimensions and position match, that the road in front is at least as wide as the approved width, and that the OSR area actually exists and is not being sold as plots. A layout where the park has quietly become “premium plots” is a red flag.
4. Match the plan with the title
The survey numbers in the approval should match the patta, chitta and FMB sketch, and the seller’s chain of title. Our guide to patta, chitta and EC explains how to read these records, and an encumbrance certificate will show whether the OSR and road areas were handed over to the local body by gift deed, which is a normal condition of layout approval.
5. Check TNRERA where it applies
Under the Real Estate (Regulation and Development) Act, 2016, a project generally needs registration when the land exceeds 500 square metres or it has more than eight units, and Tamil Nadu registers plotted layouts too. TNRERA publishes separate lists of registered normal layouts and regularisation layouts. If a sizeable layout is being marketed without a TNRERA number, ask why.
Approval types you will hear about
| What the seller says | What it usually means | What to check |
|---|---|---|
| DTCP approved | Layout approved by DTCP or an LPA under it | Approval number, year, plan, your plot in the plan |
| LPA approved | Approved by the local planning authority (for example Coimbatore LPA) | Same checks as DTCP |
| Regularised plot | Old unapproved plot regularised under the 2017 rules | Regularisation order for that individual plot |
| Panchayat approved | Usually only a local resolution, not layout approval | Treat as unapproved until proven otherwise |
| RERA registered | Project registered with TNRERA | Registration number on the TNRERA site; still verify planning approval |
Red flags that should stop you
- The approval number cannot be traced, or it belongs to a different village or survey number.
- Your plot number does not appear in the approved plan, or the plan has been “revised” without a new approval.
- Roads on site are narrower than approved, or the OSR is missing.
- The land sits on or next to a water body, poramboke land or under high tension lines.
- The seller says approval is “in process” and pushes for a large advance now.
What if the plot is not approved?
Tamil Nadu has a scheme to regularise unapproved plots and layouts, but it is limited to plots sold and registered on or before 20 October 2016. Plots carved out after that date without approval cannot use it, and without approval you may struggle to get a building permit, service connections or a home loan. See our guide to regularisation of unapproved plots in Tamil Nadu for how that scheme works.

Frequently asked questions
Is a DTCP approval number printed on a brochure enough?
No. Treat it as a claim to verify. Check the number with the approving office or the official portal, and confirm your own plot number appears in the approved plan.
What is the difference between DTCP and LPA approval in Coimbatore?
Both are planning approvals under the Tamil Nadu Town and Country Planning Act. The Coimbatore Local Planning Authority approves layouts inside its planning area, while DTCP offices handle areas outside it. Banks and local bodies treat both as valid layout approvals.
Does a TNRERA registration mean the layout is DTCP approved?
Registration with TNRERA requires planning approvals, so a registered layout should have them, but you should still check the approval and plan yourself. RERA registration and planning approval are separate records.
Can I get a building permit on an unapproved plot?
Generally not, unless the plot has been regularised. Plots sold and registered on or before 20 October 2016 may be regularised under the 2017 rules; others usually cannot.
