Mumbai Setback Rules
Municipal Corporation of Greater Mumbai (BMC) (MCGM)
The DCPR 2034 is the operative bye-law governing setbacks, building height, and FSI for plots in Mumbai under MCGM jurisdiction (Category Greater Mumbai (Island City + Suburbs + Extended Suburbs)). 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 |
|---|---|
| Less than 12 m (Island City) | 3 m |
| Less than 12 m (Suburbs) | 4.5 m |
| 12 - 21 m | 4.5 m |
| ≥ 21 m | 6 m |
- For high-rise buildings >70 m, total front open space (including road) shall be at least 9.0 m on at least one accessible side; for buildings >120 m, on two sides.
- For corner plots abutting two or more roads, road-side margin applies on every abutting side.
- Road-widening setback is in addition to the front open space; FSI/TDR for surrendered land is computed per Reg. 30 & 32.
Side & Rear Setback — Apartments & Other Buildings
| Building height | Rear margin | Side margin | Notes |
|---|---|---|---|
| Up to 15 m (low-rise) | 1.5 m | 1.5 m | Minimum marginal open space for fire and ventilation |
| > 15 & ≤ 24 m | 3 m | 3 m | — |
| > 24 & ≤ 70 m (high-rise) | 6 m | 6 m | At least one side accessible from road shall have 9.0 m clear at ground level for fire-fighting |
| > 70 & ≤ 120 m | 6 m | 6 m | At least two sides accessible from road shall have 9.0 m clear at ground level for fire-fighting |
| > 120 m | 6 m | 6 m | Subject to High-Rise Technical Committee approval (constituted under Reg. 19(2A)). Minimum road width 18 m. |
- Marginal open spaces are measured from the building line, not the plot line — building line excludes any chajja, weather-shade, or balcony projections up to 1.2 m.
- DCPR 2034 allows fungible compensatory area up to 35% (residential) and 20% (commercial) for built-up encroachment, subject to premium payment under Reg. 31(3) — does not relax the minimum marginal open space requirement.
- For redevelopment under Reg. 33(7) / 33(7)(A) / 33(10), reduced front open space may be permitted subject to CFO NOC.
Maximum Building Height
| Road width | Max height | Notes |
|---|---|---|
| ≥ 9.0 m | 70 m | High-rise — Above 32 m up to 70 m |
| ≥ 12.0 m | 120 m | High-rise — Above 70 m up to 120 m |
| ≥ 18.0 m | 999 m | High-rise — Above 120 m (no upper limit per DCPR; subject to AAI clearance + High-Rise Committee approval) |
| ≥ 12.0 m (Special / Assembly up to 32 m) | 32 m | Special buildings or Assembly buildings with height up to 32 m |
| ≥ 18.0 m (Special / Assembly above 32 m) | 999 m | Special buildings or Assembly buildings above 32 m height |
- Building height is regulated primarily by FSI (which varies by zone) and slenderness ratio rather than a hard cap by road width.
- Buildings near civil airports must comply with AAI height clearance: within 2,438 m of an international airport or 1,829 m of any other civil airport.
- DCPR 2034 height categories: Low-rise (≤15 m), Medium (15-24 m), High-rise (>24 m, with specific technical requirements above 32 m, 70 m, and 120 m).

What governs setbacks in Mumbai?
Building setbacks in Mumbai are regulated by the Development Control and Promotion Regulations 2034 (Greater Mumbai) (DCPR 2034), notified by the Municipal Corporation of Greater Mumbai · Govt. of Maharashtra on 2018-05-08. The regulation applies across all Category Greater Mumbai (Island City + Suburbs + Extended Suburbs) areas — meaning both the Municipal Corporation of Greater Mumbai (BMC) (MCGM) city limits and the broader 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 DCPR 2034 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 Mumbai 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 DCPR 2034 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 Greater Mumbai (Island City + Suburbs + Extended Suburbs) rules. Mumbai 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 DCPR 2034. If your plot is in any of these zones, consult the full DCPR 2034 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 Mumbai?
Per DCPR 2034 Table 6.24, the minimum road-side margin (front setback) for Category D1 plots in Mumbai 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 Mumbai?
For a single-family dwelling on a plot between 150 and 300 sq.m, DCPR 2034 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 Mumbai?
Maximum building height under DCPR 2034 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 Mumbai?
Yes. Single-family dwellings (Dwelling 1 and Dwelling 2 in DCPR 2034) 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 Mumbai?
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 DCPR 2034. 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 DCPR 2034 document?
The official Development Control and Promotion Regulations 2034 (Greater Mumbai) PDF is published by the Municipal Corporation of Greater Mumbai · Govt. of Maharashtra and hosted on portal.mcgm.gov.in (Sanctioned DP-2034 official). 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 — DCPR 2034 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 DCPR 2034 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.
Mumbai is split into Island City and Suburbs; setback (front open space) rules differ slightly. Side and rear marginal open spaces are primarily driven by building height under DCPR 2034. Special rules apply for redevelopment under Reg 33(7), 33(7)(A), 33(10), and for high-rise buildings >32m / >70m / >120m.
