Take an identical 200 sq m residential plot fronting a 9m road and run it against four Indian planning authorities’ own gazetted bylaw tables. The permitted buildable area ranges from 290 sq m (Gurugram) to 600 sq m (Delhi — DDA) — a 2.07× spread, for authorities two of which sit within 30 km of each other in the same metro region. Every figure below is a deterministic lookup against a cited statute clause, computed live by the same function that powers White Warp’s free FSI calculator — not hand-typed, not a survey, not a model estimate.

Buildable area = permitted FAR × 200 sq m plot area, per authority’s own cited table. Bar length is proportional to buildable area; not to scale of an actual floor plan.
The core comparison
These four authorities are the only ones White Warp’s engine currently holds a page/clause-cited bylaw table for AND that support residential-plotted lookups by plot size — the same bar every number in the free FSI calculator has to clear before it ships.
| Authority | FAR | Coverage | Buildable area | Ground footprint | Max height | Source |
|---|---|---|---|---|---|---|
| Delhi — DDA (planned colonies) | 3.00 | 75% | 600 sq m | 150 sq m | 15m | DDA Handbook on Development Controls 2021, p.3-4 (Master Plan for Delhi 2021, Cl. 4.4.3) verified May 2026 |
| Gurugram (DTCP / HSVP, Non-Core) | 1.45 | 75% | 290 sq m | 150 sq m | 16.5m | Haryana Building Code 2017, amended 06.11.2024, Cl. 6.3(3)(i)(a) verified May 2026 |
| Noida (NOIDA Authority) | 1.80 | 75% | 360 sq m | 150 sq m | 15m | NOIDA Building Regulations 2010, Reg. 24.1 / Table 1 (p.63) verified May 2026 |

White Warp’s engine also carries tables for Delhi MCD and Greater Noida (GNIDA) — both are excluded from this study because the engine itself marks them verified: false:
Extended panel
Hyderabad, Bengaluru, Pune and Gujarat are not yet wired into White Warp’s live FSI calculator, so they cannot be run through the same 200 sq m / 9m standardized input as the core four above without extrapolating beyond what the source table actually states. Each row below instead uses that authority’s own already-published worked example — plot sizes and road widths differ by row; read the FAR/coverage columns, not a cross-row buildable-area comparison.
| Authority | Worked plot | FAR | Coverage | Buildable area | Source |
|---|---|---|---|---|---|
| Hyderabad — GHMC / HMDA | 150 sq m (≈ 179 sq yd), 12m road | 2.00 | 50% | 300 sq m | GHMC Building Bye-laws 2012 (GO Ms. No. 168 MA&UD, as amended for Telangana), Regulations 6–8 |
| Bengaluru — BBMP / BDA | 500 sq m (≈ 598 sq yd), 15m road | 2.25 | 65% | 1,125 sq m | BDA Revised Master Plan 2015, Volume III (Zoning of Landuse and Regulations), Table 10 |
| Pune — PMC (UDCPR 2020) | 250 sq m (≈ 299 sq yd), 15m road | 1.10 | 50% | 275 sq m | Unified Development Control & Promotion Regulations 2020 (UDCPR), Maharashtra, Reg. 6 |
| Gujarat — CGDCR 2017 (AUDA / SUDA / VUDA / RUDA / JADA) | 500 sq m (≈ 598 sq yd), 12m road | 1.80 | 41% | 900 sq m | Comprehensive General Development Control Regulations (CGDCR) 2017, Notification No. GH/V/269 of 2017/EDB-102016-3629-L, dated 12-10-2017 |
Methodology
Source. Every figure traces to one named, dated statute: the Master Plan for Delhi 2021 / DDA Handbook 2021 (Delhi DDA), the Haryana Building Code 2017 as amended 06.11.2024 (Gurugram), NOIDA Building Regulations 2010 (Noida), and the Tamil Nadu Combined Development and Building Rules 2019 (Chennai/CMDA) — plus, in the extended panel, GHMC Building Bye-laws 2012 (Hyderabad), BDA Revised Master Plan 2015 (Bengaluru), UDCPR 2020 (Pune) and CGDCR 2017 (Gujarat). Each row above links directly to the source document.
How the core four were derived. The core comparison is not hand-typed. It is computed at page-render time by calling computeFsi() in lib/fsi-data.ts— the identical function White Warp’s free public FSI calculator uses — with a fixed input (200 sq m plot, 9m abutting road, residential-plotted use) across all four authorities. That function is a deterministic band lookup against the cited statute table, not a statistical or machine-learning estimate; the same inputs will always produce the same outputs, and the source code is inspectable.
Sample size.This is not a survey — it is a census of the Indian planning authorities White Warp’s own engine currently holds a citation-backed bylaw table for. That is 4 authorities in the standardized core comparison and 4 more in the extended panel (8 total), out of many more authorities in India whose bylaws White Warp has not yet digitised to this standard. A larger n is a roadmap item, not a claim made here.
Why 200 sq m / 9m road.200 sq m (≈239 sq yd) is a common urban plotted-residential size and sits inside every core authority’s lowest FAR/coverage band, so the comparison isn’t distorted by one city’s small-plot bonus tier against another’s large-plot tier. 9m is a standard secondary/collector road width; it was chosen (over the more common 12m) purely because it falls inside a single unambiguous premium-FSI band for Chennai and avoids an edge-of-band rounding artifact — it is not cherry-picked for the highest spread (running the same four authorities at 12m instead still gives a 2.07× spread, since Delhi DDA and Gurugram’s FAR tables don’t vary by road width and Noida’s doesn’t either).
