Ahmedabad Setback Rules
Ahmedabad Municipal Corporation (AMC) · Ahmedabad Urban Development Authority (AUDA)
The CGDCR 2017 is the operative bye-law governing setbacks, building height, and FSI for plots in Ahmedabad under AMC / AUDA jurisdiction (Category D1 (excluding GMC)). 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.

What governs setbacks in Ahmedabad?
Building setbacks in Ahmedabad are regulated by the Comprehensive General Development Control Regulations 2017 (CGDCR 2017), notified by the Govt. of Gujarat, Urban Development & Urban Housing Department on 2017-10-12. The regulation applies across all Category D1 (excluding GMC) areas — meaning both the Ahmedabad Municipal Corporation (AMC) city limits and the broader Ahmedabad Urban Development Authority (AUDA) 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 CGDCR 2017 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 Ahmedabad 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 CGDCR 2017 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 D1 (excluding GMC) rules. Ahmedabad 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 CGDCR 2017. If your plot is in any of these zones, consult the full CGDCR 2017 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 Ahmedabad?
Per CGDCR 2017 Table 6.24, the minimum road-side margin (front setback) for Category D1 plots in Ahmedabad 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 Ahmedabad?
For a single-family dwelling on a plot between 150 and 300 sq.m, CGDCR 2017 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 Ahmedabad?
Maximum building height under CGDCR 2017 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 Ahmedabad?
Yes. Single-family dwellings (Dwelling 1 and Dwelling 2 in CGDCR 2017) 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 Ahmedabad?
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 CGDCR 2017. 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 CGDCR 2017 document?
The official Comprehensive General Development Control Regulations 2017 PDF is published by the Govt. of Gujarat, Urban Development & Urban Housing Department and hosted on ahmedabadcity.gov.in (Official AMC notification). 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 — CGDCR 2017 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 CGDCR 2017 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.
Ahmedabad falls under CGDCR 2017 Category D1, applicable to AMC + AUDA jurisdiction. Gandhinagar Municipal Corporation (GMC) and D9 categories follow separate tables.
