The Housing and Urban Development Department, through G.O. Ms No. 201, Housing and Urban Development (UD4(1)), dated 19 December 2025, notified amendments made by the Governor of Tamil Nadu to the Tamil Nadu Combined Development and Building Rules, 2019. The amendments revise the definition of "Act" and change the requirements for land reserved for community recreational purposes, known as OSR, in institutional and industrial developments.
What the notification changes
The Housing and Urban Development Department notification, G.O. Ms No. 201, Housing and Urban Development (UD4(1)), dated 19 December 2025, makes two changes to the Tamil Nadu Combined Development and Building Rules, 2019. It was published in the Tamil Nadu Government Gazette as No. SRO A-1/2026.
The Governor of Tamil Nadu made the amendments using powers under the Tamil Nadu Town and Country Planning Act, 1971, the Tamil Nadu Panchayats Act, 1994, and the Tamil Nadu Urban Local Bodies Act, 1998.
Revised definition of Act
The amendment substitutes the definition of "Act" in rule 2. Under the revised definition, "Act" means all three of the following laws:
- The Tamil Nadu Town and Country Planning Act, 1971.
- The Tamil Nadu Panchayats Act, 1994.
- The Tamil Nadu Urban Local Bodies Act, 1998.
OSR land in institutional and industrial developments
The amendment substitutes the explanation relating to community recreational space in rule 41. For institutional developments and industrial developments:
- The local body cannot insist that land earmarked for community recreational purposes, described as OSR, be gifted to it.
- The land owner must maintain the OSR space.
- Maintenance by the land owner is subject to supervision and monitoring by the concerned local body.
- The OSR land does not have to directly abut a public road.
- If the OSR land does not abut a public road, adequate and safe access must be ensured through proper spatial planning.
- Access may be provided through internal roads, pathways, or other means.
Who may be affected
The revised OSR requirements directly concern land owners and developers of institutional developments and industrial developments. They also affect the local bodies responsible for supervising and monitoring the privately maintained OSR space.
A buyer, owner, developer, planner, or professional dealing with an institutional or industrial property may need to check how the project identifies OSR land, who is responsible for its maintenance, and whether the approved layout provides adequate and safe access to it.
