The CMDA on Wednesday locked and sealed a building in Madipakkam along Bazaar Road in Ramnagar area for violating sections 56 and 57 of the Town and Country Planning Act, 1971.

The owner had obtained planning permission from the Chennai Corporation on April 18 for construction of stilt floor (parking) plus two floors residential building with four dwelling units. However, he completed ground floor plus three floor commercial building deemed to be used for commercial purpose, CMDA said.

A Stop Work Notice was issued on June 26 but the work continued. As the owner failed to comply with the notice, lock and seal and demolition notices were issued on July 19 and September 18. These failed to evoke response. Hence the action.
