CMDA (Chennai Metropolitan Development Authority) is responsible for statutory planning and zoning in the Chennai Metropolitan Area. It ensures a building is constructed according to civic rules (FSI, setbacks, etc.). TNRERA (Tamil Nadu Real Estate Regulatory Authority) is a consumer protection body that ensures builders deliver projects on time and as promised. A project must have CMDA approval before it can apply for RERA registration. At Amudha Civil Construction, 100% of our projects secure both approvals before public launch, ensuring zero legal risk for our buyers.
