DDA has 23 Industrial Estates. The allotment of industrial plots was made under different schemes mainly shifting of industries from non-conforming to conforming areas up to 1976 and also by way of auction.
No auction of industrial plots was held during the last 10 years and this was mainly due to the Supreme Court Judgment in the case of V/s Union of India in which the available industrial plots are being asked by the Delhi Govt. for relocation of industries from non-conforming area. Scheme for conversion of leasehold to freehold has been extended to industrial plot. .
