Amendment to the Tamil Nadu Combined Development and Building Rules, 2019 (11 May 2020)
The Municipal Administration and Water Supply Department issued Government Order Ms. No. 51, Municipal Administration and Water Supply (MA1), dated 11 May 2020, to amend the Tamil Nadu Combined Development and Building Rules, 2019. The amendment expands the list of municipal corporation laws referred to in the rules and replaces requirements concerning maximum building height and side and rear setbacks, including specific requirements for schools and primary schools.
What the amendment covers
The Amendment to the Tamil Nadu Combined Development and Building Rules, 2019 was notified by the Municipal Administration and Water Supply Department through Government Order Ms. No. 51, Municipal Administration and Water Supply (MA1), dated 11 May 2020. It changes three parts of the Tamil Nadu Combined Development and Building Rules, 2019.
The changes were made under powers drawn from the Tamil Nadu Town and Country Planning Act, 1971 and the legislation governing municipalities, panchayats and the listed city municipal corporations.
Changes to corporation references
The amendment to rule 2 adds references to three more city corporation laws after the Dindigul City Municipal Corporation Act, 2013:
- Hosur City Municipal Corporation Act, 2019.
- Nagercoil City Municipal Corporation Act, 2019.
- Avadi City Municipal Corporation Act, 2019.
This change is relevant where the application of the building rules depends on the municipal corporation legislation listed in rule 2.
Maximum building height
The amendment to rule 35 replaces item B in the relevant table. The substituted entries provide the following height and floor combinations:
- Ground floor plus two floors, or stilt plus three floors, subject to a maximum height of 12 metres.
- Ground floor plus one floor, or stilt plus two floors, subject to a maximum height of 9 metres.
- Ground floor plus two floors, or stilt plus three floors, subject to a maximum height of 12 metres.
The supplied table does not identify the category heading attached to each of these columns. A buyer, owner or professional should therefore check which column applies to the particular site and proposal before relying on a height limit.
Setbacks for schools
The amendment to rule 37 replaces the side setback and rear setback entries under serial number D. For both side and rear setbacks:
- One table column specifies nil generally, but 2 metres for schools.
- Another table column specifies 6 metres generally, but 3 metres for primary schools.
These requirements directly affect school and primary school building proposals falling within the relevant table categories. They may influence the buildable area of a plot, so the applicable setback column should be confirmed when reviewing plans or approvals.
