Amendments to the Tamil Nadu Combined Development and Building Rules, 2019 (2025)
The Housing and Urban Development Department issued G.O. Ms. No. 161, Housing and Urban Development [UD4(1)], dated 15 October 2025, to amend the Tamil Nadu Combined Development and Building Rules, 2019. The amendments replace reclassification and conversion terminology with “Change of Use of Land” and introduce a separate Form-IA application for owners, developers or power agents seeking such a change.
What the notification changes
The Housing and Urban Development Department issued G.O. Ms. No. 161, Housing and Urban Development [UD4(1)], dated 15 October 2025. It was published in the Tamil Nadu Government Gazette Extraordinary on 16 October 2025 as No. SRO A-26(a)/2025.
The amendments standardise the expression used in the Tamil Nadu Combined Development and Building Rules, 2019. References to “Conversion of Land Use”, “Re-classifications”, “Re-classification” and “reclassification” are replaced with “Change of Use of Land”.
Separate application for land use changes
The amended Tamil Nadu Combined Development and Building Rules, 2019 require an application for Change of Use of Land to be submitted to the competent authority in Form-IA in Annexure-IA. The application must be accompanied by proof of ownership, a site cum topography plan and other relevant material.
Form-A is also revised:
- The words referring to change of use of land are removed from its heading.
- Items 6, 7 and 9 are omitted.
- The remaining specified items are renumbered.
These changes separate a Change of Use of Land application from the matters covered by Form-A.

Form-IA requires a stamp size photograph of the applicant and asks for:
- Postal address and mobile number.
- Extent of the site.
- Present land use and details of any existing building.
- Proposed land use and proposed construction or development.
- Whether the site forms part of, or lies in, an approved layout.
- The approval date and reference number, where applicable.
- Width and status of the adjoining road, including whether it is private or public.
The form provides for signatures from the applicant, identified as the owner, developer or power agent, and from a registered professional.
