1. Chennai Metropolitan Development Authority (CMDA)

For properties within the Chennai Metropolitan Area (CMA), the CMDA is the primary authority overseeing urban planning and zoning. The CMA encompasses several municipal corporations, including Greater Chennai, Tambaram, Avadi, and Kancheepuram, as well as multiple municipalities and panchayats spread across the districts of Chennai, Thiruvallur, Kancheepuram, Chengalpattu, and Ranipet. The CMA is divided into three zones: North, Central, and South.​ 

To access zoning maps for areas within the CMA, you can visit the CMDA’s official website or contact their office directly. They provide detailed master plans and zoning information that can guide your land use decisions.​

2. Directorate of Town and Country Planning (DTCP) – Tamil Nadu

For regions outside the CMA, the DTCP is responsible for urban planning and zoning regulations. They oversee the preparation and implementation of master plans for various towns and rural areas across Tamil Nadu.​

To obtain zoning maps for areas under the DTCP’s jurisdiction, you can visit the DTCP’s official website or reach out to their regional offices. They provide access to land use maps, planning permissions, and other relevant documents essential for understanding zoning classifications and regulations.​

3. Local Municipalities and Panchayats

For specific localities, especially in smaller towns or rural areas, local municipal offices or panchayats can be valuable resources. They maintain records such as Field Measurement Books (FMB), Patta documents, and other land records that indicate zoning classifications and permissible land uses.​

Visiting the local administrative offices or their official websites can provide access to these documents. Engaging with local officials can also offer insights into any recent changes or developments in zoning regulations that may not yet be reflected in official publications.
