GDCR FSI Norms by Road Width
| Road Width (m) | Base FSI | Max Permissible FSI | Max Permissible Height |
|---|---|---|---|
| 12m Road | 1.8 | 2.2 | 21 Meters |
| 18m Road | 1.8 | 2.7 | 30 Meters |
| 36m Road | 1.8 | 3.6 | 45 Meters |
| 45m–60m Arterial (SG Highway) | 1.8 | 4.0 (TOD/C2) | 70 Meters |
Frequently Asked Questions: GDCR FSI Rules
What is FSI (Floor Space Index) under Gujarat GDCR?
Floor Space Index (FSI), also known as Floor Area Ratio (FAR), is the ratio of the total permissible covered built-up area on all floors of a building to the total area of the plot. Under the Gujarat Comprehensive GDCR, permissible FSI is determined primarily by fronting road width and master plan zoning.
What is the difference between Base FSI and Chargeable FSI?
Base FSI (typically 1.8 in urban Gujarat) is permitted by statutory right upon standard plan sanction fees. Chargeable FSI (Premium FSI) is additional permissible development rights purchasable from the municipal planning authority (AUDA, AMC, or GUDA) at designated Jantri rate percentages.
What is the maximum FSI permitted along SG Highway in Ahmedabad?
Along the 60m SG Highway arterial corridor, plots falling within Commercial (C2) zoning or designated Transit-Oriented Development (TOD) corridors can achieve a maximum combined FSI of up to 4.0, subject to minimum plot size and road setback requirements.
