The four numbers that matter
- Setback: the open margin you must leave between the building and each plot boundary (front, rear and sides).
- Ground coverage: the share of the plot the ground floor may cover, often 50–75% for small plots.
- FAR / FSI: total built-up area on all floors divided by plot area. With an FAR of 1.75 on a 1,200 sq ft plot you can build 2,100 sq ft in total.
- Height limit: often linked to road width, for example G+2 or 11.5 m on narrow roads.
Typical setbacks by plot size
These are typical ranges seen across Indian municipal bylaws, shown to help you plan. They are not the rule for your city.
| Plot area | Example sizes | Front | Rear | Each side | Ground coverage |
|---|---|---|---|---|---|
| Up to 600 sq ft | 15×30, 15×40, 20×30 | 3–5 ft | 0–3 ft | 0 | 70–80% |
| 600–1,200 sq ft | 20×40, 25×40, 30×40 | 5–7 ft | 3–5 ft | 0–3 ft | 60–75% |
| 1,200–2,400 sq ft | 30×50, 30×60, 40×60 | 7–10 ft | 5 ft | 3–5 ft | 55–65% |
| Above 2,400 sq ft | 50×80 and up | 10–15 ft | 5–10 ft | 5 ft | 50–60% |
Using the plans with setbacks
The plans here cover the full plot so they can be compared easily. To use one on your plot:
- Subtract the setbacks from your plot. A 30 × 40 plot with a 6 ft front, 3 ft rear and 3 ft sides leaves a 24 × 31 ft buildable area.
- Pick a plan from the next smaller plot size (here, 25 × 30), or ask your architect to shrink the plan's rooms.
- The front setback can usually hold your car parking, gate and garden, so a plan with front parking can lose that row.
- Check whether a balcony may project into the setback. Many cities allow 3–4 ft projections on upper floors.
Approvals you will need
- Building plan sanction from the municipal corporation, development authority or panchayat.
- Structural stability certificate from a licensed structural engineer (often required for G+1 and above).
- Water, sewer and electricity connections, applied for separately.
- Completion or occupancy certificate after construction, needed for the final power connection and resale.
Always confirm the current rules with your local authority or a licensed architect before buying land or starting work. Building beyond the approved plan can lead to fines or demolition.
