Revised Setback Rules in Bengaluru 2025: What Plot Owners Must Know

Planning to build a house in Bengaluru or purchase a residential plot?
Understanding the latest setback rules in Bengaluru (2025) is essential before you finalize your design or apply for plan approval.

In November 2025, the Government of Karnataka proposed amendments to the Revised Master Plan–2015, bringing important changes to setback calculations, building height limits, basement permissions, and parking norms.

This guide explains those updates clearly—without legal jargon—so homeowners and plot owners can make confident decisions.

Bengaluru Building Rules 2025 - Official Setback Regulations Guide

What Are Setback Rules and Why Are They Important?

Setbacks are the minimum open spaces required between a building and the plot boundary. These open spaces ensure:

  • Natural light and cross ventilation
  • Fire safety access
  • Rainwater percolation
  • Privacy between neighbouring buildings

Incorrect setback planning is one of the most common reasons for plan rejection and construction delays in Bengaluru.

Major Update: Height-Based Setback Calculation

Buildings up to 12.0 metres height

For all buildings with a total height up to 12.0 m (excluding stilt floor), setbacks must be calculated only as per Table 8.

This applies to:

  • Independent houses
  • Duplex homes
  • Most low-rise residential buildings

This clarification removes earlier confusion where multiple tables were interpreted differently.

New Setback Rules for Residential Plots (Table 8)

Residential Plot Setback Calculation Blueprint for Bengaluru Plots

Plots up to 60 sq.m

  • Front setback: 0.75 m
  • Side setback: 0.60 m on any one side
  • Rear setback: Not required

Ideal for compact plots in older residential layouts.

Plots above 60 sq.m up to 150 sq.m

  • Front: 0.90 m
  • Rear: 0.70 m
  • Side: 0.70 m on one side

This category includes most 30×40 sites in Bengaluru.

Plots above 150 sq.m up to 4000 sq.m

Setbacks are calculated as a percentage of plot dimensions:

  • Front: 12% of site depth
  • Rear: 8% of site depth
  • Left & right sides: 8% of site width each

Percentage Based Setback Calculation Guide for Larger Residential Plots

Plots above 4000 sq.m

A minimum setback of 5.0 m on all sides is mandatory.

Minimum 5m Setback Requirements for Plots Over 4000 sq.m in Bengaluru

Maximum Building Height for Small Plots

For plots up to 150 sq.m:

  • Maximum permissible height: 12.0 m
  • Stilt floor is excluded from height calculation

This allows practical G+2 or G+3 residential buildings when designed correctly.

Basement Rules in Bengaluru (2025)

Minimum setback for basements

For plots up to 4000 sq.m, basement setback shall be:

  • The required building setback (Table 8 or 9), or
  • 2.0 m,
    whichever is less

Owner responsibility

The property owner is fully responsible for:

  • Safety of neighbouring structures
  • Repairing any damage caused during basement construction

Parking & Ramp Rules: Mechanized Systems Allowed

The revised rules permit:

  • Mechanized parking
  • Hydraulic parking
  • Car lifts

Parking may be provided in:

  • Basements
  • Upper floors
  • Terrace levels

Mandatory conditions

  • Exclusive staircase access to basement
  • Natural ventilation and drainage
  • Compliance with National Building Code
  • Structural design as per IS Codes, certified by a registered engineer

Ramp Width Requirements

Ramp widths depend on the number of parking spaces:

  • Up to 25 cars: 3.5 m wide, single ramp
  • Up to 200 cars: Two ramps or one 6.0 m ramp
  • Larger developments require additional access

If mechanized parking is used, conventional ramps may not be mandatory.

Basement Restrictions in Flood-Prone Areas

Basements are not permitted in:

  • Flood-prone areas
  • Low-lying zones notified by authorities

This rule is strictly enforced for safety reasons.

What This Means for Home Buyers

Before finalizing a plot or house design:

  • Confirm setback eligibility early
  • Check basement feasibility
  • Plan parking strategically

Most approval delays occur due to misunderstanding—not violation—of regulations.
