Delhi Development Authority (DDA) is the statutory development authority responsible for planning and development functions across Delhi. It was created in 1957 under the Delhi Development Act and works in areas such as housing, land management, land disposal, planning, development of public spaces and other urban-development activities.
Vikas Sadan at INA is DDA’s main office and is also an important point of contact for housing, land and public-interface matters. At the same time, many services are now available online through DDA’s AAWAS, citizen-service and departmental portals. Applicants should use the service connected with their housing scheme or property rather than expecting one universal login for every DDA function.

Delhi Development Authority Online Login
Housing applicants generally use DDA’s New AAWAS Portal for current housing-scheme services. Other property matters may use separate online systems such as IDLI, housing citizen services or land-management services.
A typical housing login process is:
- Open the official DDA website.
- Choose the New AAWAS Portal or the relevant online public service.
- Register or sign in using the credentials requested by that service.
- Select the current housing scheme or property service.
- Complete applicant or allottee details.
- Upload documents where required.
- Complete payment or booking steps, if applicable.
- Save the application, registration and transaction details.
Because DDA operates several systems, users should follow the instructions displayed for the exact service they need.
How to Check DDA Application or Allotment Status
The correct status facility depends on the type of application.
| Requirement | DDA Facility to Check |
| Housing registration/allotment | Registration/Allotment Query |
| Priority status | Priority Status facility |
| Payment details | Housing Registration Query / Payment Details |
| Mutation, address change, cancellation or refund | Relevant request-status facility |
| PM-UDAY application | Applications Status tab in PM-UDAY portal |
| Current housing booking | New AAWAS applicant account |
Applicants should keep the registration number, application details and payment information used during submission. If a status page asks for a particular reference number, use the number issued for that service rather than a general DDA file number.
Delhi Development Authority Housing Schemes
DDA periodically launches housing through first-come, first-served booking, draw of lots and e-auction formats. Scheme status changes frequently, so dates should always be checked on the current housing page.
As of September 2026, DDA’s official website shows recent or active housing activity including:
- DDA Nagrik Awaas Yojana 2026, with an official extension up to 30 September 2026
- DDA Karmajeevi Awaas Yojana 2026
- DDA Towering Heights Karkardooma Housing Scheme 2026 under FCFS format
- DDA Premium Housing Scheme 2026 through e-auction
- Additional flats and booking-related updates under current housing initiatives
A scheme name appearing in the DDA archive does not necessarily mean booking is open. Check the latest circular, brochure and AAWAS portal before paying a registration or booking amount.
