The Delhi Development Authority (DDA) has revised its policy governing additions and alterations in DDA flats, with the new rules taking effect on July 1, 2026. According to reports from Zee News and Real Estate News, the revised policy has been rationalised in consultation with the Ministry of Housing and Urban Affairs to provide clearer guidelines for homeowners seeking to modify their properties. The new framework categorises alterations into three categories based on the level of permission required, with minor changes now permitted without prior approval.
Under the revised framework, residents can now carry out several minor alterations without taking prior permission or even informing the authorities, provided these changes do not affect the structural stability of the building. As reported by Zee News and Real Estate News, permitted works include grills and glazing in the verandah, raising the height of the front and rear courtyard wall up to seven feet, providing doors in the front and rear courtyard, raising the wall of the balcony or terrace parapet with grill or glazing up to 5 feet height, installing EV charging points, and putting an additional PVC water tank in the ground floor area. These changes represent a significant expansion of what homeowners can do without official approval.
Prior permission or intimation will be required for additions or alterations that are of a major nature which may require structural modification, changes in the service lines and additional coverage. According to the revised policy reported by Zee News and Real Estate News, these include removal of the original structure and reconstruction with approval and sanctioning from the concerned sanctioning authority, interchanging the position of kitchen, bathroom and toilet after obtaining the necessary plumbing approvals, extension of the existing common staircase to the terrace level allowed along with provision of mumty, subject to ensuring structural safety, installation of solar panel for domestic use is allowed, subject to provisions in UBBL-2016, covering of courtyard up to the floor level of the first floor as permanent structure is allowed, and construction of bathroom and WC in the rear courtyard subject to proper provision of plumbing system with direct connection to the existing internal and external drainage, sewage and water supply system without disturbing the existing services. For works requiring approval, the owners must obtain the approved architectural plan of the flat from the DDA or MCD and have the proposed alterations prepared and certified by a registered architect.

As reported by Zee News and Real Estate News, the DDA has introduced online submission requirements where persons making additions or alterations must submit proposals along with supporting documents and prescribed fees. The authority will examine proposals and communicate its decision within 30 days of submission. After completing construction, owners must inform the authority with intimation of completion given within 3 years of submission of plans to the concerned sanctioning authority.
The revised policy applies only to DDA housing up to G+4 storeys. According to the DDA guidelines reported by Zee News and Real Estate News, after completing construction, owners must inform the authority with intimation of completion given within 3 years of submission of plans to the concerned sanctioning authority. If no intimation regarding completion of construction is received within 3 years, the permission granted will automatically get revoked and withdrawn. All provisions under the policy shall be governed by regulations ensuring no encroachment on public land, structural stability and safety of the building, and no infringement of others' rights.
