# Live: Tamil Nadu real estate trackers > Daily-updated status of the regulations, projects and disputes that change what you can buy or build in Tamil Nadu. Published by Verified.RealEstate. Each tracker has an HTML page, a JSON twin (append .json) and an RSS feed (append /feed.xml). ## Trackers - [CRZ notifications and coastal zone plans](https://verified.realestate/live/crz-notifications-tamil-nadu): As of 19 September 2026, Tamil Nadu’s CRZ controls and coastal zone plans are in force, with recent enforcement affecting Chennai and the ECR. A buyer or owner must verify the plot’s CRZ category and applicable plan before buying, building or altering a boundary, because unauthorised work can face demolition or eviction. - [HR&CE temple land recovery and lease notices](https://verified.realestate/live/hrce-temple-land-notices): As of 19 September 2026, HR&CE temple-land recovery and lease controls remain in force. On 7 September 2026, the Supreme Court upheld eviction from temple land. A buyer or owner must verify whether the exact plot is recorded or claimed as temple property, and whether any lease, fair-rent demand or eviction action affects it. - [Ennore and north Chennai industrial zoning](https://verified.realestate/live/ennore-north-chennai-industrial-zoning): As of 19 September 2026, the tracker remains unclear because no zoning notification, final land-use order or court resolution is reported. A buyer or owner must not treat the latest immersion, dredging or fish-kill actions as proof of permitted use for a specific plot. - [Flood-prone area notifications and lake restoration](https://verified.realestate/live/chennai-flood-zone-notifications): As of 13 September 2026, flood-prone area controls and development around Pallikaranai marsh remain challenged, with no court resolution reported after the wetland authority’s 21 August position. A buyer or owner must check the specific parcel’s flood, wetland and water-body status. Preparedness works do not establish that construction is permitted. - [Pallikaranai marsh and the Ramsar buffer](https://verified.realestate/live/pallikaranai-marsh-ramsar): As of 14 September 2026, construction controls around Pallikaranai marsh remain challenged in pending High Court litigation. TNSWA has proposed an interim, scientifically prepared Zone of Influence instead of a complete prohibition. A buyer or owner must verify the parcel against the marsh, reserve forest and proposed zone before relying on development potential. - [Wetland notifications and sanctuary buffers](https://verified.realestate/live/wetland-sanctuary-buffers): As of 11 September 2026, wetland and sanctuary buffer rules remain challenged, with Pallikaranai before the Madras High Court and a related state Bill still only proposed. A buyer or owner must confirm the rule applying to the exact site, because the record supports neither a blanket construction ban nor blanket permission. - [TNHB estate redevelopment](https://verified.realestate/live/tnhb-12-acre-flat-redevelopment): As of 8 September 2026, Tamil Nadu has proposed a ₹2,883 crore plan to rebuild flats, but the estates, timetable and affected residents have not yet been reported. A buyer or owner must not assume a particular TNHB colony or parcel is included without parcel-specific confirmation. - [Bengaluru Chennai Expressway in Tamil Nadu](https://verified.realestate/live/bengaluru-chennai-expressway): As of 9 September 2026, the Bengaluru Chennai Expressway remains challenged because the contractor’s Madras High Court case over a stalled package has not been reported resolved. NHAI terminated the contract and invited replacement bids. Buyers should not price a parcel on the expected 2028 opening until its actual access is verified. - [Chennai airport expansion and NOC zones](https://verified.realestate/live/chennai-airport-expansion): As of 17 September 2026, Chennai airport’s broader expansion, including Terminal 5, remains proposed, while T3 work continues. No specific change to height NOC zones or new airport land need has been reported. A buyer or owner should verify the current height restrictions for the exact plot before relying on expansion plans. - [Chennai second airport site selection](https://verified.realestate/live/chennai-second-airport-site-selection): As of 18 September 2026, Chennai’s replacement second-airport site remains proposed. Cheyyur is reported as the likely choice, after Cheyyur and Gummidipoondi were identified for a pre-feasibility study, but no location has been formally selected or notified. Buyers and owners should not assume that any village is confirmed for acquisition. - [Chennai water and sewer network expansion](https://verified.realestate/live/chennai-water-supply-expansion): As of 19 September 2026, this tracker remains challenged because the NGT sought an updated report on sewer connections near Puzhal Lake on 31 August and no later event resolves that proceeding. Buyers and owners must confirm that their specific plot can receive both connections, since merged-area eligibility is not yet reported. - [Parandur greenfield airport land acquisition](https://verified.realestate/live/parandur-airport-acquisition): As of 14 September 2026, Tamil Nadu has withdrawn the Parandur airport and its related acquisition plan. However, the state has not decided how land already acquired will be reused. A buyer or owner must verify whether the exact survey parcel was acquired or remains subject to any recorded acquisition action. - [SIPCOT industrial parks and land acquisition](https://verified.realestate/live/sipcot-industrial-parks): As of 19 September 2026, SIPCOT's wider wave of industrial parks remains proposed. SIPCOT allocated ₹43 crore for Manapparai on 18 September, but its use was not reported. A buyer or owner must verify whether a specific plot is covered by an acquisition notification, because village and parcel details are not yet reported. - [Hosur master plan and new town development](https://verified.realestate/live/hosur-master-plan): As of 8 September 2026, the Hosur master plan and new town development remain proposed. The government still supports the related airport proposal despite opposition over farmland. Buyers and owners must check the current zoning and any parcel-specific acquisition notice before relying on proposed land-use changes. - [SPEED single window for building approvals](https://verified.realestate/live/ai-speed-building-plan-approvals): As of 21 August 2026, SPEED remains proposed. It was announced on 6 August as an AI-enabled system for Chennai building plan scrutiny and approvals. A launch date, operational workflow and wider Tamil Nadu rollout are not yet reported, so buyers and owners should not assume current approval steps have changed. - [E-registration and Tnreginet process changes](https://verified.realestate/live/tnreginet-e-registration): As of 15 September 2026, Tamil Nadu’s latest reported registration change is a proposal for 25 Model Registration Hubs, while Anywhere Registration and online first-sale registration were reported in force on 19 August. A buyer of a new plot or flat must confirm the online process and appointment position before fixing completion. - [Forged deed cancellation and registration fraud](https://verified.realestate/live/deed-fraud-cancellation): As of 8 September 2026, the proposal remains at the bill-passed stage. A registration bill permitting document cancellation passed on 2 September, but its provisions, commencement date and final notification are not yet reported. Buyers and owners must therefore verify whether any cancellation claim or forgery allegation affects the specific land. - [TNRERA rules, fees and registration](https://verified.realestate/live/tnrera-rules-fees): As of 17 September 2026, TNRERA registration and compliance requirements remain in force. On 16 September, the Madras High Court said TNRERA cannot decide contested ownership and directed those claims to civil courts. A buyer or owner must separate RERA compliance and possession issues from any dispute over who holds title. - [Chennai property tax reassessment](https://verified.realestate/live/chennai-property-tax-revision): As of 18 September 2026, Chennai's property tax reassessment stands withdrawn after the civic body revoked the increase on 15 August 2026. A buyer or owner should still verify the property's existing assessment, paid receipts and any revised demand, because earlier notices and possible arrears can affect holding costs. ## Feeds - [All changes (RSS)](https://verified.realestate/live/feed.xml)
