What is the procedure for getting CMDA approval in Chennai ?

The Chennai Metropolitan Development Authority is the body responsible for taking care of the approval process before the construction of any landform or structure.

  • The first step would be categorising: Form “A” is for laying out landforms, Form “B (Special buildings, etc.) & C (industries, etc.)" are for construction.
  • To obtain CMDA approval, a series of drawings must be submitted, which must be made in accordance with the standard rules and regulations established by CMDA, failing which approval may not be granted. The list of drawings includes - Detailed site plan, Key plan, Floor plans, Elevations and Sections, which have to be attested by a surveyor or architects in Chennai. Documents such as the Sale or lease deed and clearance from the competent authority should be submitted.
  • Approximately 45 days would be adequate to obtain approval from the date of filing. Once approval is obtained, construction should take place within 3 years, failing which the approval will expire and the same procedure has to be repeated.
  • If any construction is carried out by the Building Contractors in Chennai without proper approval, it would be considered unauthorised and can be demolished anytime as per bylaws.
  • In case any revisions are made to the original approved plan, the same has to be submitted again for the approval process.
  • Once your application is approved, a demand will be sent to you by the local authority / CMDA for payment, and this rate will depend on the land use purpose and the area. These construction sites would be Inspected by Government officials.
  • Special and multi-story buildings with more than 4 floors (G+3) can be directly applied to the CMDA, whereas the Chennai City Municipal Corporation / Municipality / Town Panchayat / Panchayat Union also have the power to issue approval for buildings in the case of ordinary buildings.
