Bangalore Setback Rules
Bruhat Bengaluru Mahanagara Palike (BBMP) · Bangalore Development Authority (BDA)
The BBMP Bye-laws 2003 is the operative bye-law governing setbacks, building height, and FSI for plots in Bangalore under BBMP / BDA jurisdiction (Category BBMP limit (Bangalore Mahanagara Palike Building Bye-laws 2003)). Front-side margin is driven by abutting road width; side and rear margins for single-family dwellings depend on plot size; for apartments and other uses the side and rear margins scale with building height. Use the calculator below for a quick lookup, or scroll to the full tables.
Front Setback (Road-side Margin)
| Road width | Front setback |
|---|---|
| 1.5 m | |
| 1.5 m | |
| 1.5 m | |
| 3 m | |
| 4.5 m | |
| 6 m |
- Setbacks for very small plots (<50 sq.m) and irregular plots may be relaxed under Bye-law 4.7. Verify with BBMP Town Planning Department.
- For sites in BDA-allotted layouts, the BDA-allotment-specific setback may apply (often more relaxed for sites pre-2003).
Side & Rear Setback — Apartments & Other Buildings
| Building height | Rear margin | Side margin | Notes |
|---|---|---|---|
| Up to 11.5 m (G+3) | 3 m | 3 m | Standard low-rise apartment margin |
| > 11.5 & ≤ 15 m (G+4) | 4 m | 4 m | — |
| > 15 & ≤ 21 m (G+6) | 5 m | 5 m | — |
| > 21 & ≤ 30 m (G+9) | 6 m | 6 m | — |
| > 30 & ≤ 40 m (G+12) | 7 m | 7 m | — |
| > 40 & ≤ 55 m | 9 m | 9 m | — |
| > 55 m (high-rise) | 12 m | 12 m | 12-16 m depending on height; subject to BBMP Special Buildings Committee + CFO NOC |
- Front setback for apartments follows the road-width-based table (Table 4) but capped at minimum 6 m for high-rise.
- Distance between two buildings on the same plot shall equal the side margin required for the taller building.
- Special Buildings (height >18 m or G+4 in BBMP definition) require CFO NOC and structural design review per Bye-law 12.
Maximum Building Height
| Road width | Max height | Notes |
|---|---|---|
| < 9.0 m (< 30 ft) | 11.5 m | G+3 typical residential |
| 9 - 12 m (30-40 ft) | 15 m | G+4 |
| 12 - 15 m (40-50 ft) | 18 m | G+5 |
| 15 - 18 m (50-60 ft) | 21 m | G+6 |
| 18 - 24 m (60-80 ft) | 30 m | G+9 |
| ≥ 24 m | 999 m | No upper cap, subject to AAI clearance, FAR limits per zone, CFO NOC |
- Building height is also bounded by FAR (zone-based per RMP-2031) — typically 1.75 to 4.0 depending on zone.
- Bangalore (Bengaluru) is within Kempegowda International Airport approach zones — AAI height clearance required for plots within prescribed approach corridors.

What governs setbacks in Bangalore?
Building setbacks in Bangalore are regulated by the Bangalore Mahanagara Palike Building Bye-laws 2003 (with amendments) (BBMP Bye-laws 2003), notified by the Bruhat Bengaluru Mahanagara Palike · Govt. of Karnataka on 2003-09-13. The regulation applies across all Category BBMP limit (Bangalore Mahanagara Palike Building Bye-laws 2003) areas — meaning both the Bruhat Bengaluru Mahanagara Palike (BBMP) city limits and the broader Bangalore Development Authority (BDA) jurisdiction. Three structural factors determine your minimum setbacks: abutting road width (controls front margin and max height), plot size (controls side/rear for single-family), and building height (controls side/rear for apartments).
Front setback — driven by road width
The front (road-side) margin under BBMP Bye-laws 2003 starts at 2.5 m for roads up to 9 m wide and scales up to 9.0 m for roads 45 m and wider. For most residential plots in Bangalore on a typical 30-40 ft (9-12 m) road, the front setback is 2.5 to 3.0 m. Corner plots must observe the road-side margin on every abutting road, which can significantly reduce buildable area on tight plots. Special buildings — high-rises above 25 m, hospitals, hotels, malls, educational institutions — must keep a uniform 12.0 m road-side margin regardless of road width.
Side and rear margins — driven by plot size for residences
For single-family and two-family dwellings (DW1 and DW2 in BBMP Bye-laws 2003 terminology), side and rear margins are determined by plot area. Tiny plots up to 25 sq.m are exempt (with G+1 cap). Plots between 25 and 150 sq.m need only 1.0-1.5 m on any one side. Once plot size crosses 150 sq.m, a mandatory 2.0 m rear margin kicks in. Plots above 500 sq.m must keep 3.0 m on both sides plus 3.0 m rear. This graduated structure gives smaller, dense urban plots more buildable area while ensuring breathing room in larger plots.
Apartments and commercial — driven by building height
Multi-family, mixed-use, and commercial buildings (anything other than DW1-DW2 and industrial) follow a different logic: the taller the building, the larger the side and rear margins. A low-rise apartment up to 16.5 m needs 3.0 m on every side. Buildings between 16.5 and 25 m need 4.0 m. Buildings between 25 and 45 m need 6.0 m. Anything above 45 m needs 8.0 m. This scaling protects fire access and inter-building daylight as buildings get taller.
Margin between buildings on the same plot
Group housing schemes and multi-block developments must observe an internal margin between buildings as well, separate from plot boundaries. Per Table 6.25, this ranges from 4.5 m for buildings up to 16.5 m, to 12.0 m between buildings of 70 m. Margin from a designated common plot (open recreation area within a layout) is 3.0 m for buildings up to 25 m, and 6.0 m above that. These rules are critical at the master-plan stage; missing them means redesigning blocks late in DA approval.
Coverage of overlays and special zones
The setback tables on this page cover the standard Category BBMP limit (Bangalore Mahanagara Palike Building Bye-laws 2003) rules. Bangalore additionally has overlay zones with their own special regulations: the Sabarmati Riverfront Development zone, GAMTAL (urbanised village) areas, Core Walled City (heritage), Smart City Node (SPD5), Knowledge Precinct, and Closed Textile Mills Zone (CZ). Plots within these overlays follow the standard setback rules plus the overlay-specific provisions in Sections 7.2-7.6 and 8.1-8.4 of BBMP Bye-laws 2003. If your plot is in any of these zones, consult the full BBMP Bye-laws 2003 PDF (download link at the top of this page) before designing.
Frequently asked questions
What is the minimum front setback for a residential plot in Bangalore?
Per BBMP Bye-laws 2003 Table 6.24, the minimum road-side margin (front setback) for Category D1 plots in Bangalore ranges from 2.5 m on roads up to 9 m wide, to 9.0 m on roads of 45 m or more. For a typical 30 ft (≈9 m) wide road, the front setback is 2.5 m; for a 40 ft (≈12 m) road it's 3.0 m; for an 18 m road it jumps to 6.0 m.
What is the side and rear setback for a 200 sq.m plot in Bangalore?
For a single-family dwelling on a plot between 150 and 300 sq.m, BBMP Bye-laws 2003 requires a rear margin of 2.0 m and a side margin of 1.5 m on any one side. The other side may abut the boundary. This is per Table 6.26 of the regulation.
What is the maximum building height allowed in Bangalore?
Maximum building height under BBMP Bye-laws 2003 is governed by the abutting road width (Table 6.23). On roads less than 9 m wide, height is capped at 10 m (12 m for DW1/DW2 type residential). On 9-12 m roads it goes up to 16.5 m, on 12-18 m roads up to 30 m, and on 18 m and wider roads up to 45 m. In High Density Development Areas (where permitted FSI exceeds 3.5) on 18 m+ roads, height up to 70 m is allowed within 200 m of the road.
Are setback rules different for apartments vs single-family homes in Bangalore?
Yes. Single-family dwellings (Dwelling 1 and Dwelling 2 in BBMP Bye-laws 2003) have setbacks driven by plot size (Table 6.26). Apartments and other multi-family or commercial buildings have setbacks driven by building height — 3.0 m for buildings up to 16.5 m, 4.0 m for 16.5-25 m, 6.0 m for 25-45 m, and 8.0 m for buildings above 45 m. Front (road-side) margins follow the same Table 6.24 for both categories.
How do I calculate setbacks for my plot in Bangalore?
Use three inputs: (1) plot size in square metres, (2) abutting road width in metres, and (3) intended use (single-family, apartment, commercial). The lookup tables on this page give exact values per BBMP Bye-laws 2003. For corner plots, road-side margin applies on every abutting side. The setback calculator at the top of this page returns front, side, rear, and max height in one click.
Where can I download the official BBMP Bye-laws 2003 document?
The official Bangalore Mahanagara Palike Building Bye-laws 2003 (with amendments) PDF is published by the Bruhat Bengaluru Mahanagara Palike · Govt. of Karnataka and hosted on site.bbmp.gov.in (BBMP Acts & Bye-laws portal). Use the "Download PDF" button at the top of this page for direct access. The regulation is approximately 600 pages; setbacks are covered in Section 6.7 (Margins) and Tables 6.23 through 6.41.
Do these rules apply to plots in AUDA areas outside the AMC limit?
Yes — BBMP Bye-laws 2003 is a state-level regulation that applies uniformly across Category D1 plots, which covers both AMC (city corporation) and AUDA (urban development authority) jurisdictions. The same Tables 6.24 and 6.26 govern setbacks. Gandhinagar Municipal Corporation (GMC) plots fall under separate tables (6.28 onwards) due to its planned-grid layout. Special zones (Riverfront, Heritage Core, GAMTAL, Smart City Node) have their own overlay rules in addition to base setbacks.
What happens if my plot doesn't meet the minimum setback?
Existing buildings in revenue records before the publication of BBMP Bye-laws 2003 are typically protected by transitional provisions. New construction or major alteration must comply with current setbacks. For sub-25 sq.m plots, only G+1 construction is permitted with no mandatory setback. For plots affected by road widening, owners can claim FSI compensation against the original boundary (Section 6.3.3) provided the surrendered land is formally transferred. Always consult a licensed architect for plot-specific guidance.
Bangalore is governed by the BBMP Building Bye-laws 2003 (with amendments through 2018) for setbacks and FAR. The BDA Revised Master Plan-2031 (RMP-2031) governs zoning and FSI. BBMP setback tables are driven by site dimensions (depth × width) plus road width — historically more granular than the post-1995 metric-only tables of other cities.
