1. Check the 'commencement certificate" for the "file no." and take the commencement certificate, to the building proposal dept., of the Municipal Corporation.
2. IF the registered architect has submitted compliances THEN "completation certificate" copy would be on record. Just simply move plain applicaiton for a certified copy of the "commencement certificate". As also suggested by above experts, you can also use the RTI application route for obtaining the same. IT is very simple.
