What is Building Plan Approval in Tamil Nadu?

Building plan approval is the permission granted by the Tamil Nadu Town and Country Planning Department (TNTCP) and the local body (Corporation, Municipality, or Panchayat) to construct or modify a building. It ensures that your construction follows the Development Regulations (DR), CMDA/DTCP norms, safety standards, and zoning rules.

Without plan approval, your building will be considered unauthorized, leading to penalties, demolition notices, or denial of electricity and water connections.
