What is land conversion in Tamil Nadu?
Definition
Land Conversion in Tamil Nadu, formally Change of Land Use (CLU), is the order issued by the local authority with the prior concurrence of the Director of Town and Country Planning, converting agricultural land to non-agricultural use. It is governed by the Tamil Nadu Change of Land Use (From Agriculture to Non-Agriculture Purposes in Non-Planning Areas) Rules, 2017 in non-planning areas, and by Section 32 of the Tamil Nadu Town and Country Planning Act, 1971 (Master Plan reclassification) in planning areas.
A Patta classifies land as Nanjai (wetland), Punjai (dryland), or Manavari (rainfed). The CLU order converts that classification to non-agricultural before any construction is legal. Sellers offering "agricultural land suitable for housing" without a CLU order are selling the obligation to convert. Buyers either pay the conversion charge themselves or face demolition. The Madras HC and the local body enforce the T\&CP Act on unconverted construction.
The 2017 Rules cover non-planning areas under DTCP. Planning areas (CMDA, LPA, NTDA) use the Master Plan reclassification process. Both routes need a 3% market value conversion charge under the Indian Stamp Act 1899, plus a ₹1,000 scrutiny fee. Wetlands need Collector concurrence after a personal site visit under Section 47A. Drylands need a report from the Joint Director of Agriculture. The agricultural to non-agricultural conversion file must reach the Director through the local body, not direct.
State-specific note: Without conversion, construction on agricultural land is illegal under the T\&CP Act 1971. The local body will refuse building permission. The Sub-Registrar may refuse to register sub-divisions of unconverted Nanjai land.

How to Get a Land Conversion Order in Tamil Nadu: Step-by-Step on onlineppa.tn.gov.in
Two routes get you a CLU Tamil Nadu order. The Tamil Nadu Single Window Portal at onlineppa.tn.gov.in handles online filing for non-planning and planning areas. Offline filing goes to the local body and DTCP regional office. Have the Form-I land conversion form, Patta Chitta, FMB sketch, EC, sale deed, and the latest market valuation ready before starting.
Online method (recommended)
1
Open the Single Window Portal Visit [onlineppa
tn.gov.in](http://onlineppa.tn.gov.in). Register as a citizen with name, mobile, email, and Aadhaar. The portal serves both DTCP non-planning area conversions and planning area reclassifications under one workflow.
2
File the CLU application Choose Change of Land Use under Citizen Services
Fill Form-I with district, taluk, village, survey number, sub-division, current classification (Nanjai, Punjai, Manavari), proposed use (residential, commercial, industrial), and extent. Upload Patta, Chitta, FMB, EC, and the latest sale deed.
3
Pay the scrutiny fee Pay the ₹1,000 non-refundable scrutiny fee online
The local body acknowledges the application within 7 working days under the 2017 Rules. The Director Town Country Planning then takes the file forward.
4
Site verification and final order For wetlands, the Collector visits the site personally under Section 47A
For drylands, the Joint Director of Agriculture submits a report. After concurrence, pay the 3% market value conversion charge. The conversion order issues within roughly a month, and the Patta Chitta classification is updated. * ###
* Keep the market valuation document from a recent registered sale deed nearby. The 3% conversion charge is computed on the value under the Indian Stamp Act 1899, so any dispute on valuation slows the order.
Offline method (Sub-Registrar Office)
1
Visit the local authority Submit Form-I to the Municipality, Town Panchayat, or Village Panchayat covering the parcel
Carry the original Patta Chitta, FMB sketch, EC, sale deed, ID proof, and the proposed development brief.
2
Local authority forwards to Director The local authority acknowledges within 7 days
It forwards the file to the Director of Town and Country Planning with its site inspection report. The Director cannot grant permission without this prior concurrence chain.
3
Wetland Collector visit or dryland Agriculture report For Nanjai land, the Collector visits the site personally and assesses cultivation history, irrigation source, and impact on canals
For Punjai land, the Joint Director of Agriculture submits a report. Exempted lands (water bodies, Poromboke, temple, Wakf) cannot be converted.
4
Pay charges and collect order On approval, pay 3% of the market value as conversion charge plus the ₹1,000 scrutiny fee
The Revenue Officer makes the necessary entries to update the Patta Chitta classification. The conversion order is issued by the local authority on Director concurrence. *
* Demand the conversion order copy in writing along with the updated Patta Chitta. A verbal "approval" from the local authority without a stamped order has no legal effect.

What Does a Land Conversion Order Contain in Tamil Nadu?
Each CLU order is a formal proceedings document. Mismatch on any field against the Patta or the proposed development is a transfer-blocking defect.
| Field | What it means | What to check |
|---|---|---|
| Conversion Order Number | Unique reference issued by the local authority | Verify with the local authority and on Patta Chitta update |
| Survey Number and Sub-division | Land parcel identifier | Match against Patta, FMB, and sale deed |
| Original Classification | Nanjai, Punjai, or Manavari | Confirms the source classification before conversion |
| Converted Use | Residential, commercial, industrial, or institutional | Determines what construction is legally permitted |
| Extent Converted | Area in hectares or square metres | Match against the parcel being purchased |
| Conversion Charge Paid | 3% of market value plus ₹1,000 scrutiny fee | Receipt copies must be on file |
| Director Concurrence Reference | Director of Town and Country Planning approval reference | Confirms statutory route was followed |
| Collector Concurrence (wetland) | Personal site visit and concurrence under Section 47A | Mandatory only for Nanjai conversions |
Good sign: A clean conversion order shows a numbered local authority proceedings, Director concurrence reference, paid 3% conversion charge receipt, updated Patta Chitta classification, and Collector concurrence for any wetland conversion.

Common Issues With Land Conversion in Tamil Nadu
Each CLU order is a formal proceedings document. Mismatch on any field against the Patta or the proposed development is a transfer-blocking defect.
Construction without conversion order
The Buyer Warning is direct: without conversion, construction on agricultural land is illegal under the T\&CP Act 1971. Buyers building on Nanjai or Punjai parcels without CLU face stop-work orders, demolition notices, refused electricity and water connections, and refused building permission. *
Fix: * Verify the converted classification on the Patta Chitta on eservices.tn.gov.in before any advance. Demand the CLU order copy and the 3% conversion charge receipt. No order, no construction.
Wetland sold as "convertible" without Collector concurrence
Sellers market Nanjai wetland as convertible to residential. Section 47A and the 2017 Rules require a personal Collector site visit before any wetland conversion. Without it, no conversion order issues. Buyers who pay on the seller's promise carry the conversion cost and the rejection risk. *
Fix: * Ask for the Collector's site visit report and concurrence reference. If the seller cannot produce both, walk away. Wetland conversion is the slowest and most uncertain route.
Layout sold on partially converted land
A layout developer converts 5 acres but markets plots from an unconverted adjacent 2 acres. The buyer's plot may sit in the unconverted strip even though the layout brochure shows full conversion. *
Fix: * Match the survey number and sub-division of the specific plot against the conversion order's Field Table extent. Plots outside the converted survey numbers are unconverted.
Conversion order on exempted land
Water bodies, Government Poromboke, temple lands, and Wakf properties are exempted under the 2017 Rules. Conversion orders on these parcels are void. Sellers occasionally produce backdated orders for exempted parcels. *
Fix: * Run Verify Poramboke Land on eservices.tn.gov.in before relying on any conversion order. Cross-check the A-Register classification.
3% conversion charge unpaid by seller
A sanction for conversion is granted but the seller never pays the 3% market value conversion charge. The order remains conditional and the Patta Chitta classification stays agricultural until the charge is paid. *
Fix: * Demand the conversion charge payment receipt. The order without payment receipt is incomplete. Pay the charge before sale registration if the seller has not.
Master Plan area conversion done under non-planning rules
The 2017 Rules cover non-planning areas only. Inside CMDA, LPA, or NTDA jurisdictions, Master Plan reclassification under Section 32 of the T\&CP Act 1971 applies. Sellers occasionally show 2017 Rules orders for planning area parcels. Such orders are non-applicable. *
Fix: * Confirm whether the parcel is in a planning area or non-planning area. Match the conversion order route to the jurisdiction. A 2017 Rules order inside CMDA limits is non-actionable.

Why Land Conversion Matters for Land Buyers in Tamil Nadu
The CLU order is the single document that decides whether agricultural land can legally host residential, commercial, or industrial construction.
Legalises non-agricultural use of agricultural land Without the conversion order, the land remains agricultural in revenue records and under the T\&CP Act 1971
Construction is unauthorised. The local body refuses building permission. Banks refuse to fund construction.
Mandatory before any construction is legal The Buyer Warning is direct: without conversion, construction on agri land is illegal
The 2017 Rules and Section 32 of the T\&CP Act 1971 set the framework. Buyers who skip CLU face demolition, fines, and refused utility connections.
Required for DTCP / CMDA layout approval and bank loans Layout approvals from DTCP or CMDA require the underlying parcel to be converted to residential or the relevant non-agricultural use
Banks pull the converted Patta Chitta before sanctioning home loans on plots from former agricultural land.
Tamil Nadu-specific: Wetland conversion needs Collector site visit Section 47A of the T\&CP Act 1971 requires the Collector to personally visit the site before any Nanjai wetland conversion
The 2017 Rules made the procedure detailed and stricter, including impact on irrigation channels, groundwater, and storm water drains.
Red flag: If a seller in Tamil Nadu offers "convertible agricultural land" without showing the CLU order copy and the 3% conversion charge receipt, walk away. Verbal promises of conversion are not orders.

Browse Verified Tamil Nadu LandsFrequently Asked Questions
What is Land Conversion Tamil Nadu?
Land Conversion Tamil Nadu is the formal Change of Land Use order converting agricultural land to non-agricultural use. It is issued by the local authority with concurrence of the Director of Town and Country Planning under the Tamil Nadu Change of Land Use Rules, 2017.
What are the charges for converting agricultural land in Tamil Nadu?
A non-refundable scrutiny fee of ₹1,000 is paid to the local authority. The conversion charge is 3% of the market value of the land under the Indian Stamp Act, 1899. Both must be paid before the order is issued and the Patta Chitta classification is updated.
Can wetland be converted to residential in Tamil Nadu?
Yes, but the District Collector must personally visit the site under Section 47A of the T\&CP Act, 1971. The Collector verifies cultivation history, irrigation impact, and groundwater effects. Wetland Collector concurrence is the slowest and most uncertain conversion route in Tamil Nadu.
How long does the land conversion process take in Tamil Nadu?
The local authority acknowledges the application within 7 days. After Director and Collector or Agriculture Department concurrence, the conversion order issues within roughly a month for clean dryland cases. Wetland conversions or contested cases take significantly longer.
What lands cannot be converted in Tamil Nadu?
Public water bodies (channel, tank, canal, lake, river), Government Poromboke land, temple lands, Wakf properties, religious or charitable institution lands, lands with public road encroachments, and lands below high-tension power lines are exempted from conversion under the 2017 Rules.
Is land conversion required before building permission?
Yes. The local body refuses building permission on agricultural classification land. The CLU order must be issued and the Patta Chitta classification updated to non-agricultural before any plan approval, DTCP or CMDA layout sanction, or construction loan can move forward.
What is the difference between non-planning area conversion and Master Plan reclassification?
Non-planning areas use the Tamil Nadu Change of Land Use Rules, 2017 through the local authority and DTCP. Planning areas (CMDA, LPA, NTDA) use Master Plan reclassification under Section 32 of the T\&CP Act 1971. The two routes are not interchangeable.
What happens if I build on agricultural land without conversion?
Construction on unconverted agricultural land violates the T\&CP Act 1971. The local body issues stop-work orders and demolition notices. Building permission is refused. Bank loans are denied. Resale value collapses. Regularisation under Section 113-C is paid and uncertain.
