OMR - Rajiv Gandhi Salai

Two issues quietly decide whether a plot on this corridor will hold value or turn into a frozen asset. One is proximity to Pallikaranai. The other is a thin land-records trail no one bothered to verify.

The Pallikaranai Marsh, designated India's Ramsar site on 8 April 2022, covers 1,247 hectares and sits right alongside the IT corridor. The Chennai Second Master Plan 2026 already classifies the contiguous swamp area as conservation land where development is prohibited. The recent escalation matters more. On 24 September 2025, the National Green Tribunal Southern Bench ordered CMDA to stop issuing all new approvals inside the Ramsar boundary and its zone of influence, and signalled that even plots outside the marsh, but within a one-kilometre buffer, may be restricted until the Tamil Nadu State Wetland Authority completes a scientific delineation.

The table below shows the OMR localities where this Pallikaranai marsh NGT order directly bites, so you know which postcodes carry an active approval freeze.

Patta chitta verification Tamil Nadu is the second non-negotiable. Pull the patta and chitta directly from the Tamil Nadu eServices portal at eservices.tn.gov.in. For Chennai Corporation pockets, ask for the TSLR Extract; for periurban villages on the lower OMR, ask for the A-Register and the 1-B Register. Cross-check the survey number against the Field Measurement Book sketch and the encumbrance certificate. If the seller balks at any of these, treat it as a decision. The eServices portal also lets you verify whether the parcel is poramboke, which along OMR often means tank-bed or drainage land that was never legally saleable in the first place.

The OMR splits cleanly into three bands. The upper stretch from Madhya Kailash to Tidel Park is a built-out office-led market with limited fresh land. The middle band from Perungudi to Sholinganallur carries the densest job catchment and the highest end-user demand. The lower stretch from Navalur to Kelambakkam is the supply belt, where new layouts and group housing are still being sanctioned.

The table below summarises how the master plan treats the corridor's principal localities and where the genuine investment depth sits.

Rajiv Gandhi Salai IT Corridor regulations allow a notably higher FSI than the general residential zones in the metropolitan area. Annexure XIII of the Second Master Plan permits IT development across the 500 m belt regardless of the underlying land use, subject to the corridor's own conditions. That single clause is what turned Sholinganallur and Navalur from peripheral villages into a 38% chunk of South Chennai's residential absorption in Q1 2026.

Siruseri SIPCOT IT Park is the most misread node on the corridor. Brokers sell every adjacent village layout as "Siruseri-rate" land, but the 868-acre government-developed IT Park sits inside a defined SIPCOT boundary. Anything outside that boundary is village land governed by the surrounding panchayat layout rules, not the IT Park's premium pricing. The same scrutiny applies at Kelambakkam. Cross-check the SIPCOT plot map and the CMDA sanctioned layout before treating any "near IT Park" listing at face value.
