Tamil Nadu Expands Building Plan Approval Powers for Local Bodies

The Tamil Nadu government has expanded the planning approval powers of urban and rural local bodies, allowing them to approve residential and commercial building plans with higher floor space limits and increased building heights. The revised rules aim to simplify the approval process, reduce administrative delays and decentralise decision-making by enabling local authorities to grant permissions for a wider range of projects.

According to an order issued by the state’s Housing and Urban Development Department, corporations and municipalities can now approve residential buildings with a floor space index (FSI) area of up to 1,500 square metres, equivalent to around 16,140 square feet, and a maximum of 16 dwelling units. The earlier limit was 10,000 square feet.

The revised provisions are expected to make the approval process more accessible for homeowners, developers and builders undertaking residential construction. By increasing the limits within which local bodies can grant permissions, the government aims to reduce the need for additional administrative procedures for eligible projects.

Higher Approval Limits for Rural and Urban Local Bodies

Town panchayats and local bodies under the Rural Development and Panchayat Raj Department have also received expanded powers to approve residential building plans. These authorities can now grant permission for buildings with an FSI area of up to 1,200 square metres, or approximately 12,912 square feet, with a maximum of 12 dwelling units. Previously, the limit was eight dwelling units.

The government has also increased the permissible height for residential and commercial buildings that fall within the delegated approval powers of local bodies. Urban and rural authorities can now approve buildings up to 14 metres in height, subject to a maximum of stilt-plus-three floors or ground-plus-two floors, as applicable under the revised provisions. The earlier height limit for residential buildings was 12 metres.

The changes provide local authorities with greater flexibility in processing building proposals while retaining specified limits on floor space, dwelling units and building height.

Commercial Building Approvals Also Expanded

The revised rules extend to commercial construction, with corporations, municipalities, town panchayats and rural local bodies authorised to approve commercial buildings with an FSI area of up to 500 square metres, equivalent to around 5,380 square feet.

The increase is expected to simplify planning permissions for smaller commercial establishments and other eligible developments. Earlier, the Greater Chennai Corporation could approve buildings of up to 3,280 square feet, while other local bodies were restricted to 2,000 square feet.

S Ramaprabhu of the Builders Association of India-Southern Centre welcomed the decision, stating that the revised limits could help address violations arising from the misuse of buildings. The expanded approval powers are expected to give local authorities a clearer role in granting permissions for projects within their jurisdiction.

Background to the Revised Planning Rules

The latest decision follows a recommendation from the Commissioner of Town and Country Planning to expand the delegation of planning approval powers to local bodies.

In 2020, the previous AIADMK government delegated planning permission powers to local bodies, excluding Chennai. Under that arrangement, eligible authorities could approve buildings with a built-up area of up to 10,000 square feet and a maximum of eight dwelling units. The limit for commercial buildings was 2,000 square feet.

Subsequently, following representations from the Builders Association of India and CREDAI, the DMK government revised the criteria for residential building approvals by replacing the built-up area measure with FSI area. This changed the basis on which eligible residential proposals were assessed.

FSI is calculated by multiplying the plot area by the permissible FSI value. It determines the total floor area that can be developed on a particular plot, subject to applicable planning regulations.

Implications for Tamil Nadu’s Construction Sector

The expanded delegation of powers marks a further change in Tamil Nadu’s building approval framework. By allowing local bodies to approve larger residential developments and taller buildings within specified limits, the state government aims to make planning permissions more accessible and reduce procedural delays.

For developers, builders and property owners, the revised limits could simplify approvals for eligible projects. The changes may also help local authorities manage a wider range of building proposals directly, while maintaining compliance with applicable development regulations.
