Delhi Development Authority
The Delhi Development Authority (DDA) is a planning authority created in 1957 under the provisions of the Delhi Development Act "to promote and secure the development of Delhi". The DDA is responsible for planning, development and construction of Housing Projects, Commercial Lands, Land Management as well as providing public facilities like roads, bridges, drains, Underground water reservoir, Community Centers, Sports Centers, Green Belts etc. within the area of National Capital Territory of Delhi, India.
The DDA master plan was formed in 1962 to ensure an organized and structured development of haphazard growth of Delhi. This included identification of new land that can be developed into residential properties and make self-contained colonies by providing ample commercial office and retail complexes as well. The DDA master plan was revised in 1982 to formulate the Master Plan 2001 and then re-revised in 2007 to form the Delhi Master Plan 2021. It lays down the basic infrastructure requirements for a city estimated to have a population of 128 lakhs (12.8 million).
The development of housing projects by DDA commenced in 1967 with the construction of houses and providing the basic amenities like electricity, water supply, sewage disposal, and other infrastructure facilities. The new projects undertaken instigate with recognition of project sites, public announcement about the new DDA housing schemes in various categories through newspapers and other media advertisements, formal acceptance of the applications, a transparent draw system for short-listing of the applicants and finally allotment of the property.
Some popular DDA Housing Schemes of the past include New Pattern Registration Scheme that offers home registration along with the property purchase, Janta Housing Registration Scheme that offers house registrations for the economically weaker section category and Ambedkar Awas Yojana that allotted Janta, LIG & MIG (Lower and Middle Income group)category flats to the SC/ ST registrants. The residential land is allotted to individual applicants, the farmers whose land is acquired for development and group housing societies through public auction.
The 1985 housing scheme was a scheme for people with low annual income. The scheme stated that each person can participate by paying 3000 Rs draft on DDA account. The total cost of each house was 35000 Rs; recipients had to pay the balance of the amount within a few months. The scheme was subject to criticism due to delays and perceived unequal treatment of applicants. After years of dispute, a new policy was instituted in 2019 requiring submission of a 50,000 Rs draft to the Delhi Urban Shelter Improvement Board or alternatively an appreciated reimbursement of 9000 Rs was offered. 
In March 2019, DDA launched a new housing scheme, for around 18,000 flats situated in Vasant Kunj and Narela, which got a lukewarm response from the general public in terms of applications received. Most of the flats of this scheme situated at Narela were the surrendered flats of the earlier DDA Housing Scheme 2017. The results of the DDA Housing Scheme 2019 were announced in July 2019.
