Bengaluru BDA Tightens Rules for Modified Building Plans After Occupancy Certificate

The Bengaluru Development Authority (BDA) has introduced a comprehensive set of guidelines governing the approval of modified building plans after the issuance of an Occupancy Certificate (OC), marking a significant shift in the way post-construction approvals will be handled in Karnataka.

The move follows an interim order issued by the Karnataka High Court in the HM Tambourine Apartment Owners Association case, where the court directed the authority to establish clear criteria for approving revised building plans after an OC had already been granted. The judgment highlighted the need to protect apartment owners from unauthorized alterations while ensuring transparency in urban development.

Under the revised framework, developers will no longer be permitted to obtain modified plan approvals if the entire permissible Floor Area Ratio (FAR) has already been utilised and a full Occupancy Certificate has been issued. In projects where only a partial OC has been granted, builders may utilise the remaining permissible FAR only under specific conditions.

The BDA has clarified that the original site layout cannot be altered while using the balance FAR. Parks, open spaces and civic amenities approved in the original sanctioned plan must remain unchanged. In addition, where apartments have already been sold, builders must secure consent from at least two-thirds of the purchasers before seeking approval for additional construction. Sale agreements and registered documents must also clearly disclose the possibility of future utilisation of permissible FAR, Transferable Development Rights (TDR) or Premium FAR.

Another key provision ensures that any additional construction undertaken using the balance FAR, TDR or Premium FAR must not affect the undivided share of existing apartment owners. Once a final Occupancy Certificate has been issued for the entire project, developers will permanently lose the right to seek modifications.

To improve governance, the BDA has also announced plans to integrate its town planning and engineering approval systems through dedicated software, followed by an Enterprise Resource Planning (ERP) platform from April 1, 2027. Authorities have been directed to dispose of applications within 90 days.

The new guidelines are expected to strengthen regulatory oversight, reduce legal disputes between developers and residents, and improve confidence in Bengaluru’s real estate sector by ensuring greater accountability in post-approval construction activities.
