Unified Building Bye-laws for National Capital Territory of Delhi are applicable since 1983. Since then, a number of amendments/modifications, both in the Development Control Regulations (DCRs) and Building Bye-laws have been made and are in operation. The Master Plan for Delhi 2021 was notified on 7th February, 2007 and subsequently, certain Master Plan Regulations are also amended. In the present study on the applicable Bye-laws for Delhi and Development Control Regulations as amended up to 2013 were grouped together and simplified. Certain new provisions have been added to cut down the delay for sanctioning and Issue of Completion Certificate. This study has been conducted by the Delhi Urban Art Commission in consultation with the professionals (Architects and Planners).
