If you own or are evaluating a plot in Delhi, the single most important question to answer first is: Is this plot under DDA jurisdiction or MCD jurisdiction?
The answer determines your FSI — and your FSI determines how much you can build. The rules under these two bodies are fundamentally different, and the confusion between them is one of the most expensive mistakes Delhi plot buyers make.
This guide explains exactly how to tell which rules apply to your plot, what the difference means in rupees, and why smaller DDA plots can be worth more per sqm than larger ones.
Why Two Different Bodies?
Delhi has two main building regulators for residential areas:
DDA (Delhi Development Authority) — governs planned residential colonies developed directly by DDA. These include Dwarka sectors (1–23), Rohini sectors (DDA phases), Janakpuri, Paschim Vihar DDA pockets, Vasant Kunj DDA blocks, and other planned residential layouts where DDA originally allotted the plots.
MCD (Municipal Corporation of Delhi) — governs everything else. Older colonies (Civil Lines, Patel Nagar, Karol Bagh), South Delhi regularised colonies (Saket, Malviya Nagar, Green Park), East Delhi colonies, and the vast informal/regularised settlement network.
Both entities have their own building bye-laws. The FSI calculation works completely differently under each.
DDA Rules: FSI by Plot Size (DDA Handbook 2021)
Under DDA Handbook 2021, FSI for residential plots is determined by plot area:
| Plot Size | FSI | Ground Coverage |
|---|---|---|
| Up to 100 sqm | 3.5 | 75% |
| 100–250 sqm | 3.0 | 75% |
| 250–750 sqm | 2.25 | 75% |
| 750–1,000 sqm | 2.0 | 50% |
Road width plays a role under DDA rules — but it governs building height, not FSI.
The height formula: Permissible height = 1.5 × road width (metres) + 3.0 m
So on a 12m road, permissible height = 21m. On a 9m road, 16.5m. The FSI you can use is the same regardless of road width — but the height cap limits how many floors you can spread it across.
MCD Rules: FSI by Road Width
Under MCD Building Bye-laws, FSI for residential zones is determined by road width:
| Road Width | FSI |
|---|---|
| Up to 6m | 1.2 |
| 6–9m | 1.5 |
| 9–12m | 2.0 |
| 12–18m | 2.5 |
| 18–24m | 3.0 |
| Above 24m | 3.5 |
Plot size doesn't affect FSI under MCD rules. A 150 sqm plot and a 400 sqm plot on the same 12m road both get FSI 2.5.
Transit-oriented zones (within 500m of approved Metro stations, under the Delhi TOD Policy) can get up to FSI 4.0 — but this requires specific zone notification and is not automatic.
The Counter-Intuitive Result: Smaller DDA Plots Often Have Better FSI
This is the insight most buyers miss entirely.
Under DDA rules:
- 200 sqm plot → FSI 3.0 → 600 sqm buildable area
- 300 sqm plot → FSI 2.25 → 675 sqm buildable area
The 300 sqm plot gives you 12.5% more absolute buildable area — but it's 50% more land. Per square metre of land, the 200 sqm plot is significantly more efficient.
Here's the financial implication. Assume ₹9,500/sqft selling rate (Dwarka market):
200 sqm DDA plot (FSI 3.0):
- Sellable area: ~5,167 sqft
- Revenue: ~₹4.9 crore
300 sqm DDA plot (FSI 2.25):
- Sellable area: ~6,450 sqft
- Revenue: ~₹6.1 crore
The 200 sqm plot gets you ₹4.9 crore revenue. If it's priced at ₹1 Cr, you're paying ₹50,000/sqm for land. The 300 sqm plot needs to be priced proportionally to stay attractive — if it's at ₹1.7–1.8 Cr, the margin difference closes fast.
Brokers who don't know DDA rules will price 200 sqm and 300 sqm plots as if they have the same FSI. They don't. The pricing difference should be narrower than the area difference because the FSI ratio closes the gap.
How to Tell Which Rules Apply to Your Plot
Method 1: Check the Plot Allotment Letter
If the plot was originally allotted by DDA, the allotment letter will say "Delhi Development Authority" and reference a DDA scheme (e.g., "DDA Rohini Residential Scheme 1981"). These plots follow DDA Handbook 2021.
Method 2: Check the Area
Most DDA-allotted plots are in:
- Dwarka — Sectors 1 through 23 (planned pocket development)
- Rohini — DDA Phases 1-4 (Sectors 8-28 DDA sections)
- Janakpuri — DDA-developed blocks
- Paschim Vihar — DDA pocket areas
- Vasant Kunj — DDA blocks A through F
- Narela, Dwarka Expressway extension — newer DDA schemes
Older colonies (Civil Lines, Karol Bagh, Patel Nagar, Kalkaji, Green Park, Greater Kailash) are typically MCD. South Delhi regularised colonies (Saket, Hauz Khas, Malviya Nagar) are MCD.
Method 3: Check the Property Tax Records
MCD issues property tax receipts for properties under its jurisdiction. DDA does so for its own areas. The header of the demand notice tells you which body assesses the property.
Method 4: Call DDA's Helpline
DDA maintains a property records system. You can verify any plot's jurisdiction at estates.dda.org.in or by calling DDA's helpline.
The L-Zone Exception
L-Zone (Dwarka Expressway corridor, primarily sectors in South-West Delhi) is a special case. L-Zone is DDA Master Plan land but follows a different zoning policy under MPD-2041 for residential use. Some L-Zone plots may be eligible for group housing FAR up to 2.0–3.0, while others have constraints. L-Zone plots need individual verification — do not assume standard DDA Handbook 2021 rules apply without checking.
What Changes at MCD-DDA Jurisdiction Boundaries
Sometimes a single street has DDA allotments on one side and older MCD-governed plots on the other. This is more common in Rohini and Paschim Vihar, where DDA and older colony development coexist. The result: two adjacent plots of identical area on the same road can have different FSI — one DDA (plot-size-based) and one MCD (road-width-based).
If you're comparing two plots on the same street and the FSI numbers don't match, this is usually why.
Why Getting This Wrong Is Expensive
Scenario A (DDA buyer using MCD rules):
- Buyer has a 200 sqm plot in Dwarka Sector 9, 12m road
- Assumes MCD rules: 12m road → FSI 2.5 → 500 sqm buildable
- Actual DDA rule: plot ≤250 sqm → FSI 3.0 → 600 sqm buildable
- Missing 100 sqm × ~₹9,500/sqft × 10.76 = ₹10.2 lakh in potential revenue the buyer didn't know they could capture
Scenario B (MCD buyer using DDA rules):
- Buyer has a 200 sqm plot in Patel Nagar, 9m road
- Assumes DDA rules: FSI 3.0 → 600 sqm buildable
- Actual MCD rule: 9m road → FSI 1.5 → 300 sqm buildable
- Overestimates sellable area by 2× — entire feasibility projection is wrong, may overpay for land significantly
How White Warp Handles This
When you submit a plot to White Warp, the engine automatically infers jurisdiction from the location — Dwarka, Rohini DDA sectors, Janakpuri → DDA Handbook 2021 rules. Older MCD colonies → MCD building bye-laws.
The engine then:
- Applies the correct FSI for the specific plot size and jurisdiction
- Calculates permissible height (for DDA: road width formula; for MCD: separate height table)
- Computes setbacks, ground coverage, and net sellable area
- Runs the full financial model and Monte Carlo simulation
The jurisdiction call is made automatically and is shown explicitly in your report so you can verify it.

| FSI for 200 sqm plot | 3.0 | Depends on road width (typically 1.5–2.5) |
| FSI for 300 sqm plot | 2.25 | Same as 200 sqm on same road |

| Where to check | DDA allotment letter or estates.dda.org.in | Property tax demand notice from MCD |
