Setback Rules in India — HMDA, BBMP, MCGM, DDA Comparison (2026)
Every Indian Urban Local Body publishes its own setback table, FSI/FAR cap, and height limits. The numbers vary so much that a plot legal in Hyderabad would be illegal in Mumbai and over-conservative in Delhi. This is the only side-by-side comparison of the major ULB bye-laws — HMDA, BBMP, MCGM, DDA, GHMC, GMDA, and CMDA — current as of 2026.
Use this as a starting point. Final setbacks for your plot depend on plot size, road width, abutting use, and zone classification. Always cross-check the current ULB notification before construction; we maintain links per city in our DCR Hub.
What Setbacks Are and Why They Exist
A setback is the minimum unbuilt distance between your building's outer wall and the plot boundary. India recognises four:
- Front setback — distance from the road-side boundary to the front wall of the building. Largest of the four; governs streetscape and access for emergency vehicles.
- Rear setback — distance from the back boundary. Provides ventilation and prevents overshadowing the plot behind.
- Side setbacks (left + right) — distance from the side boundaries. Used for natural light and fire-spread prevention.
The basis for these is NBC 2016 Part 3 (Development Control Rules), but each state and ULB modifies it. Our NBC Part 3 explainer covers the national-level framework.

FSI / FAR Limits Across Major Cities
FSI (Floor Space Index) and FAR (Floor Area Ratio) are the same concept under different names. They cap how much built-up area you're allowed for a given plot. FSI 1.5 on a 1,000 m² plot = 1,500 m² built-up.
| ULB | Base FSI/FAR (residential) | With premium FSI | Notes |
|---|---|---|---|
| HMDA / GHMC (Hyderabad) | 1.5 – 2.0 | up to 3.5 with TDR | Recently revised — current GO 168 (2022) |
| BBMP (Bangalore) | 1.75 (≤ 7.5 m road) to 3.25 (> 30 m road) | +0.4 with TDR | Revised Master Plan 2031 framework |
| MCGM (Mumbai) | 1.33 (Island City) / 1.0 (Suburbs) | up to 5.0 (cluster redev. + TDR) | Highest premium FSI in India; complex zone-wise rules per DCPR 2034 |
| DDA (Delhi) | 1.2 – 2.0 (zone-dependent) | +10–20% mixed-use plots | Master Plan Delhi 2041 framework |
| CMDA (Chennai) | 1.5 – 2.0 | up to 3.25 (special projects) | 2nd Master Plan revision in progress |
| PMC (Pune) | 1.1 (residential) up to 4.0 (TOD zones) | +TDR available | Unified DCR 2017 |
| AMC (Ahmedabad) | 1.8 – 2.7 | up to 5.4 (CG-zone) | GDCR 2017 framework |
Building Height Limits
Height in Indian DCR is governed by 1.5× the front road width as the basic rule, then modified by FSI and zone. NBC 2016 also imposes fire-safety thresholds at 15 m, 24 m, and 60 m.
| Threshold | What changes |
|---|---|
| ≤ 15 m (G+4 typical) | Standard residential. Single staircase OK if < 12 m. |
| 15 – 24 m | Two stairs mandatory. Wet riser per NBC 2016 Part 4. Lift mandatory. |
| 24 – 45 m (high-rise) | Sprinkler system, refuge area at every 3rd floor or every 24 m. Fire NOC mandatory. |
| 45 – 60 m | Fire pump + secondary water tank. Smoke management. Pressurised staircase. |
| > 60 m (skyscraper) | Special CCS approval. Helipad if > 90 m in many ULBs. IS 16700 tall-building structural code applies. |

City-Specific Notes
HMDA / GHMC (Hyderabad)
One of India's most builder-friendly DCRs. Plots ≤ 100 m² need only 1.5 m front setback and zero on other sides. Above 200 m² it tightens. Recent GO 168 (2022) increased premium FSI to 3.5 with TDR — making Hyderabad attractive for redevelopment. Setback shortfalls can be condoned with compounding fees; this is unique to Telangana.
BBMP (Bangalore)
BBMP setbacks scale with plot size and road width simultaneously. Below 50 m² plots are common in core areas — these get heavy concessions. Bangalore enforces strict tree-cutting clearance (BTNL) before plan sanction; budget 30–60 days. The Revised Master Plan 2031 introduces TOD-zone FSI bonuses for plots within 500 m of metro stations.
MCGM (Mumbai)
India's most complex DCR — over 100 sub-clauses, premium FSI up to 5.0 in cluster redevelopment. Setbacks are larger than other metros (3 m minimum on every side for plots > 100 m²). The DCPR 2034 (Development Control and Promotion Regulations) replaced the older DCR. Treatment of fungible FSI, ancillary FSI, and TDR is unique to Mumbai and routinely requires a specialist consultant.
DDA (Delhi)
Delhi DDA plots use a "ground coverage + setback" combo unique to the capital. Master Plan Delhi 2041 (in finalisation) replaces MPD 2021. For DDA-allocated plots, setbacks are pre-approved at allotment; for private freehold plots, MCD/NDMC norms apply (slightly different).
CMDA (Chennai)
Setback rules per CMDA Development Regulations 2008 (with amendments). Tamil Nadu enforces "open space reservation" (OSR) for plots above 3,000 m² — 10% of plot area must be free open space transferable to ULB. This is in addition to setbacks.
PMC (Pune)
Pune adopted the Maharashtra Unified DCR (UDCPR) in 2020, making setbacks more uniform with MCGM. Pune-specific: TOD zone bonuses near metro stations (FSI up to 4.0), and ancestral village abadi land has separate concessions.
AMC (Ahmedabad)
Gujarat's GDCR 2017 is unusually liberal — base FSI 1.8–2.7 with simple rules. Ahmedabad and Surat permit "vertical growth corridor" zones with FSI up to 5.4 (CG zone). Setbacks scale linearly with plot size. Less premium-FSI complexity than Mumbai.
Common Setback Mistakes
Treating "buildable area" as plot size minus setbacks. Wrong. Built-up = plot × FSI, not plot − setbacks. Setbacks limit footprint per floor; FSI limits total built area across floors. Both apply.
Ignoring road-width in setback calculation. Most ULBs scale front setback with road width. A 6 m road plot in HMDA needs different setback than the same plot on a 12 m road. Verify with the current notification.
Forgetting projection allowances. Balconies, sunshades (chajjas), bay windows — each ULB has a projection allowance into the setback (typically 0.6 – 1.0 m). Don't lose buildable area by being conservative.
Over-relying on neighbour's plan. Bye-laws are revised every 3–5 years. Your neighbour's 2018 sanctioned plan is not a template for your 2026 plan.
Skipping ground coverage. Several ULBs (DDA, GHMC) cap ground coverage % independent of FSI. A plot can satisfy FSI but violate ground coverage.
Compounding Fees — When Setback Violations Are Forgiven
Most ULBs allow you to "compound" minor setback violations — pay a fee, get the violation regularised. Conditions:
- Violation usually capped at ≤ 10% of mandated setback
- Structural safety must be uncompromised
- Fee is typically 50× to 200× the regular sanction fee per sq.m of violation
- Some violations are non-compoundable: blocking fire access, building on storm drains, encroaching public road
HMDA, GHMC, and AMC are most accommodating; MCGM and DDA are stringent. Always plan within setbacks; compounding is a fallback, not a strategy.
FAQ
What's the minimum setback for a 30×40 plot (~111 m²) in Hyderabad?
HMDA: 1.5 m front, 1.0 m rear, 0.6 m on each side for plots 101–200 m². Effectively buildable footprint is ~28 × 36 ft = 1,008 sqft per floor. Hyderabad detail page.
What's the difference between FSI and FAR?
None — they're synonyms. India inconsistently uses both. FSI is preferred in Maharashtra, Gujarat, Telangana. FAR is preferred in Delhi NCR. Calculation is identical: built-up area ÷ plot area.
Are setback rules the same for residential and commercial?
No. Commercial plots typically have larger setbacks (especially front, for service entry) and lower FSI (in some ULBs) but higher ground coverage. Industrial plots have separate norms entirely. Always check the zone classification of your plot.
Can I project a balcony into the setback?
Yes, within limits. Most ULBs allow balconies / chajjas / bay windows to project 0.6 – 1.0 m into the setback at heights above 4.5 m. The projection counts as ancillary FSI in some ULBs (Mumbai), free in others (Hyderabad, Bangalore for residential).
What happens if my building violates setback after construction?
Three outcomes possible: (a) regularisation via compounding fee if violation is minor and structurally safe; (b) demolition order for the violating portion; (c) sealing of the property until rectified. The owner — not the builder — is liable in most ULB acts. Always verify completion certificate before purchase.
Where do I find the current setback notification for my city?
Each ULB publishes the latest DCR/DCPR/Bye-laws on its official website. Navigate via /dcr for direct links — we maintain a list per city, plus the notification PDFs and amendment timeline.
