The Tamil Nadu government has overhauled the procedure for converting agricultural wetlands to non-agricultural use in non-planning areas, transferring approval authority from District Collectors to the Directorate of Town and Country Planning (DTCP). The Housing and Urban Development Department issued the government order on 4 November 2026, implementing amendments to the Tamil Nadu Town and Country Planning Act, 1971, passed during the recent Assembly session.

What Has Changed

Under the earlier system, developers and landowners seeking to convert agricultural wetlands were required to first obtain clearance from the District Collector before approaching the DTCP for planning permission — a two-stage process that the construction industry had long flagged as a source of delays.

The revised framework allows the Director of Town and Country Planning to grant prior concurrence directly, collapsing the dual-approval requirement into a single window. Amendments to Sections 47-A and 9-F of the Act formally transfer this responsibility. Rule 6 of the 2017 Rules — which mandated inspection and scrutiny by District Collectors — has been deleted.

Safeguards Remain in Place

Department Secretary R. Kirlosh Kumar said the changes were intended to make the approval process more efficient without diluting regulatory oversight. Officials clarified that environmental and land-related safeguards remain unchanged, and that Rule 7 of the 2017 Rules — governing substantive scrutiny requirements — will continue to apply.

A senior DTCP official confirmed that applicants must still obtain all mandatory no-objection certificates from relevant departments. Under the new guidelines, applicants are required to upload nine prescribed documents through the online Single Window Portal. These include ownership or lease documents, patta, Chitta and Adangal records covering the previous three Fasli years, drainage plans, and topographical maps indicating developments within a 500-metre radius of the proposed site. Applicants must also submit an affidavit confirming the proposed conversion does not involve government poramboke land or property belonging to others.

Industry Response

The construction sector has welcomed the move. Representatives of the Builders Association of India said approvals under the old system typically took two to three months, and expressed hope that the revised procedure would bring processing time down to 15–30 days. The reform is expected to benefit landowners, builders and developers by enabling faster processing of land conversion applications.

Broader Policy Shift

This comes weeks after Tamil Nadu removed the requirement for Agriculture Department approval for industrial development on dry agricultural land — signalling a broader pivot by the state government towards faster clearances for construction and industrial projects. Notably, the two reforms together represent the most significant easing of land-use regulations in the state in recent years, and are likely to draw both investment interest and scrutiny from environmental groups concerned about the pace of wetland conversion. How the DTCP manages the increased workload — and whether the single-window system can deliver on the promised timelines — will determine the reform's real-world impact.
