Bengaluru Amends RMP 2015, Relaxed Setback Norms for Plots Up to 250 Sq Metres

Home builders and plot owners in Bengaluru are set to benefit from revised setback regulations, with the urban development department easing long-standing norms for small residential plots. The amended rules reduce mandatory open space requirements for plots up to 250 square metres, allowing more efficient use of land in a city where compact properties are increasingly common.

The changes have been introduced through an amendment to the Revised Master Plan (RMP) 2015, which had faced criticism for applying uniform setback norms regardless of plot size. Urban planners and civil engineers say the revised framework finally links setback requirements to actual plot dimensions and building height, offering greater design flexibility while retaining safety safeguards.

Revised Setback Norms for Smaller Plots

Under the updated Bengaluru setback rules, smaller plot categories now have clearly defined and relaxed open space requirements. For plots measuring 60 square metres (20x30 ft), builders are required to maintain a 0.7-metre front setback and 0.6 metres on each side, with no mandatory rear setback. This is expected to significantly benefit owners in dense layouts and older neighbourhoods with undersized plots.

For plots up to 150 square metres (30x40 ft), the revised norms mandate a 0.9-metre front setback, along with 0.7 metres at the rear and 0.7 metres on one side boundary. These changes allow better internal planning while still preserving minimum open space around the structure.

Height Limits and Planning Controls

For all residential plots measuring up to 250 square metres, the maximum permissible building height has been capped at 12 metres, excluding stilt floors used for parking. Officials say this height restriction balances the additional built-up space gained from relaxed setbacks while preventing excessive vertical development in residential neighbourhoods.

The amendment also brings clarity on the treatment of basements, stilt floors and parking layouts. Mechanical parking systems are now permitted on tight inner-city sites, offering a solution for space constraints in older parts of Bengaluru.

Focus on Drainage, Parking and Safety

Despite the relaxation, the rules retain a strong emphasis on environmental and safety considerations. The notification specifies that setback areas must remain free from hard paving to allow rainwater to percolate into the ground, supporting groundwater recharge.

All constructions under the revised setback norms must comply with the National Building Code (NBC) 2016, particularly provisions related to fire safety, structural stability and parking design. Authorities say this ensures that while more floor area becomes available, safety standards are not compromised.

Urban development experts believe the revised Bengaluru setback rules reflect a more practical approach to residential planning, especially in a city where land parcels are shrinking and redevelopment is on the rise. The changes are expected to make small-plot construction more viable while aligning regulations with the realities of urban growth.
