The Urban Development Department (UDD) in Bengaluru has proposed amendments to setback rules for smaller residential plots, aiming to simplify regulations and introduce uniformity. A draft notification to amend the Zoning Regulations under the Revised Master Plan 2015 was issued on 11 November, with the public invited to submit objections or suggestions within 30 days. What Is a Building Setback? A building setback refers to the minimum open space required around a structure. It determines how far a building must be positioned from plot boundaries. What the New Draft Proposes Under the new draft, setback requirements for residential plots up to 150 square metres (around 1,600 sq ft) have been reduced and fixed. Previously, setbacks had to be calculated as percentages of plot depth and width — 12 per cent at the front, 8 per cent at the rear and 8 per cent on each side — often creating confusion. The new fixed norms are: Plots up to 60 sqm (20x30 ft): 0.7 metres front setback; 0.6 metres on all other sides Plots between 60–150 sqm (30x40 ft, 30x50 ft): 0.9 metres front setback; 0.7 metres at the rear and sides Plots larger than 150 sqm: No change to existing rules Officials said the fixed distances will ensure consistency and clarity for small-plot developments. The maximum building height permitted for plots up to 150 sqm will be 12 metres, excluding a stilt floor. Open staircases will be allowed within setback areas for plots up to 750 sqm, but the setback space must remain unpaved to allow rainwater to percolate into the ground. The revised notification also permits mechanical or hydraulic parking systems — including lifts and automated platforms — in basements or on upper floors. However, basements will not be allowed in flood-prone zones. The proposed amendments aim to streamline approval processes, reduce ambiguity and support more efficient residential development across Bengaluru.
