Bengaluru real estate developers welcome Karnataka's new setback norms but warn of project delays, higher costs
Bengaluru real estate developers say reworking designs and approvals for ongoing projects could cause delays, raise costs with new setback amendments in place
Bengaluru real estate developers say the Karnataka government’s amendment to setback norms under the Revised Master Plan (RMP) 2015 will bring much-needed clarity and design flexibility, particularly for mid-rise buildings. They caution, however, that ongoing projects may face short-term redesign costs and delays in adapting to the updated requirements.
The amendment, effective August 1, updates setback standards for buildings across the city, with a particular focus on structures taller than 12 metres. Setback refers to the minimum open space between a building and the property boundary.
Under the revised rules, buildings on plots up to 4,000 sq. m must maintain at least 1.5 metres at the front and 1 metre each on the sides and rear. For larger plots, the minimum is 5 metres on all sides. Buildings with 12–15 floors but no stilt floor must have a 5-metre setback, with higher requirements for taller structures.

Clarity and livability gains
Industry experts say the codified norms will improve light, ventilation, and safety in new developments while resolving inconsistencies in earlier guidelines.
“The amended setback rules are a welcome move, particularly for buyers,” said Priyanka Kapoor, senior vice president at Research and Advisory, ANAROCK Group. “They eliminate ambiguity, especially for buildings using stilt floors for parking, and address safety concerns. But their real impact will depend on proper implementation alongside infrastructure upgrades.”
Lakshmi Prasad G V, Head of Liaison at Assetz, said the changes also enhance buildable potential for certain projects. “Buildings up to 15 metres in height now benefit from the exclusion of stilt floors (up to 3 metres) from total height calculations, allowing one additional floor without design penalties. This improves design flexibility and enables more efficient parking layouts.”
Short-term challenges: Increased costs, likely to delay ongoing projects
While the new rules are expected to smooth approvals and improve urban design, developers admit the transition won’t be seamless.
“This amendment was required and brings standardisation, especially for taller structures,” said Anil RG, managing director, Concorde. “However, reworking designs and approvals for ongoing projects could cause delays and raise costs, and in some cases, we may need to re-evaluate project feasibility.”
Prasad of Assetz noted that the amendment applies to all existing buildings with proposed modifications and all ongoing projects, meaning some developers will have to redesign plans, incur additional approval costs, and extend timelines for projects.

Developers will likely adapt new design innovations
To adapt, developers are looking to design innovations. “Balancing FAR optimisation with setbacks requires context-specific solutions,” Prasad said. “We can use stilt floors smartly, adopt vertical stacking, and work closely with planning authorities to remain compliant without compromising viability.”
Developers say that design innovations such as vertical stacking, efficient floor plate layouts, and integrated service cores help maintain project viability even with larger setback requirements. "Additionally, engaging early with planning consultants and development authorities is crucial to optimising layouts while ensuring compliance," Prasad said.
Anil RG noted that setbacks, when designed well, can improve livability. “We should focus on optimising space without sacrificing light, air, and comfort. Setbacks, when used well, can actually enhance the livability of a project,” he said.
Overall, developers say that amended regulation fosters a more streamlined and enforceable planning regime, even though they may face short-term friction in adjusting to these standards.
