What the document changes
G.O.(Ms).No.69 dated 11 March 2024, issued by the Housing and Urban Development [UD4(1)] Department, amends the Tamil Nadu Combined Development and Building Rules, 2019. It directs publication of the appended notification in the Tamil Nadu Government Gazette, Extraordinary dated 11 March 2024.
The central change is that many provisions which previously applied to non high rise buildings up to 12 metres now apply up to 14 metres. Provisions for buildings above the threshold are correspondingly changed from above 12 metres to above 14 metres, up to 18.30 metres where specified.
Who may be affected
The amendments to the Tamil Nadu Combined Development and Building Rules, 2019 may affect owners, buyers, developers, registered architects and registered engineers dealing with non high rise buildings. They are particularly relevant where a proposed or existing building is more than 12 metres but not more than 14 metres in height, because several classifications and requirements now use the higher threshold.
