Chennai Metropolitan Development Authority (CMDA)
Chennai Metropolitan Development Authority (CMDA) is the planning authority for the Chennai Metropolitan Area — layouts and buildings inside the CMA need CMDA planning permission. Across TNRERA-registered projects whose filed approval document we have machine-read, Chennai Metropolitan Development Authority appears as the approving authority on 419 projects, with a median gap of about 4 months between planning approval and RERA registration, and 93 of them carrying regularisation charges in the approval document.
Note for plot buyers: 22% of the Chennai Metropolitan Development Authority-approved layouts here show regularisation charges in the approval document — the land was regularised rather than approved as a fresh layout. That's legal, but worth understanding before you buy.
