BDA Protects Bengaluru Apartment Owners With New Rules on Building Plan Changes

Apartment owners in Bengaluru have received a major relief after the Bangalore Development Authority introduced stricter guidelines on changes to building plans after the issuance of an Occupancy Certificate. Under the new rules, builders will no longer be able to revise approved plans according to their own requirements without getting approval from apartment owners.

The decision aims to prevent misuse of legal loopholes by developers and safeguard the rights of residents who have already taken possession of their homes. According to the new BDA circular issued on July 15, any modification in projects where ownership rights have already been transferred will require consent from at least 66 percent of apartment owners.

The authority has also clarified that revised building plans will not be approved in cases where the permitted construction capacity has already been fully utilized. This move is expected to stop developers from seeking additional construction approvals on land that has already been handed over to apartment owners.

The new regulation comes after a long legal dispute involving residents of the HM Tambourine apartment complex located in the Canara Bank Layout area of South Bengaluru. The apartment project, consisting of 241 flats, became the center of a dispute after residents alleged that a developer obtained approval for additional construction on the same property years after the original project was completed.

The apartment complex was constructed in 2003 and received its Occupancy Certificate in 2006. Although the undivided land rights were held by apartment owners, residents alleged that the builder later obtained approval for a revised plan in 2016 to construct another building on the same land without obtaining their consent.

Residents challenged the approval, claiming that their rights under the Karnataka Ownership Flats Act, 1972 and the Real Estate Regulation and Development Act, 2016 were affected. They also alleged that the builder had misused the available Floor Area Ratio rights and approached the Karnataka High Court seeking protection.

Following the BDA’s latest order, apartment owners’ associations and resident welfare groups have welcomed the decision, calling it an important step toward preventing unauthorized changes by developers. Residents believe the new rule will provide stronger protection to homeowners and ensure that future modifications in apartment projects are carried out with proper consent.

Abdul Aleem, a resident of HM Tambourine and a member of Change Makers of Kanakapura, said the decision would help address long standing concerns among apartment owners and reduce the possibility of builders taking advantage of regulatory gaps.

With Bengaluru witnessing rapid growth in residential developments, the new BDA guidelines are expected to bring more transparency to apartment projects and give residents a stronger role in decisions affecting their properties.
