FAR, Ground Coverage and Setbacks: How Much Can You Actually Build?

Current as of August 2026. Confirm against the DDA and your local sanctioning authority before acting.

Three numbers decide what a plot is worth and what can stand on it. Every client should be able to state all three for their own site before an architect is appointed, and most cannot.

The three numbers

Ground coverage is the proportion of the plot that the building's footprint may occupy, expressed as a percentage. It controls the plan.

Floor Area Ratio is the ratio of total permissible built-up area to plot area. It controls the volume. A 300 square yard plot at FAR 2.0 permits roughly 5,400 square feet of built-up area, however it is distributed.

Setbacks are the mandatory clear distances from each boundary. They control where the footprint may sit, and they interact with ground coverage, on a small plot, setbacks often make the permitted ground coverage physically unachievable.

The relationship between them is what people miss. Ground coverage and FAR together determine how many floors the building wants to be. Low coverage with high FAR produces a tower on a garden. High coverage with low FAR produces a squat block. Neither is a design decision; both are given to you before you start.

The Delhi question almost everyone gets wrong

MPD-2041 is not in force.

The draft Master Plan for Delhi 2041 was published in June 2021, attracted around 33,000 public objections and suggestions, was cleared at the Lt Governor's level, and has been awaiting final notification from the Ministry of Housing and Urban Affairs ever since. It has still not been notified.

MPD-2021, gazetted in 2007, remains the operative law. Every land use classification, every FAR figure and every development control in DDA-governed Delhi today derives from it.

This matters commercially. Zone maps and land use classifications drawn from the 2041 draft circulate widely and are presented as current authority. They are not. A plot whose 2041 draft classification differs from its 2021 classification is governed, today, by the 2021 classification. Buying, designing or budgeting against the draft is buying against a document that has no legal force and may change before it acquires any.

The draft itself is explicit on transition: projects under construction at the time of notification continue under MPD-2021 norms, and projects yet to start will revise their plans to whatever plan is then in force. Which is a fair description of the risk, if you are planning a long-cycle project now, you are planning across a regulatory boundary whose date nobody can give you.

The practical instruction: verify your plot's classification against MPD-2021 and the applicable Zonal Development Plan. Note the 2041 draft position separately, as intelligence rather than as authority. And do not let anyone show you a 2041 map as though it settled anything.

Outside Delhi

Gurugram, Faridabad, Noida and Ghaziabad each run their own framework, and the numbers differ meaningfully, by authority, by sector, by land use and by plot size. Haryana's plotted policies carry their own FAR and coverage regimes, and purchasable FAR exists in several of them, meaning the headline figure is not the ceiling.

The rule that holds everywhere: FAR is site-specific and category-specific. There is no general answer, and a figure quoted for a neighbouring plot is not a figure for yours.

What else eats into the number

Even once you have the FAR, the built-up area you can actually use is smaller than it looks.

• What counts and what does not. Basements below ground, stilt parking, mumty, service areas and shafts are treated differently by different authorities. Some are FAR-free, some are not, and this single question can move the usable area by ten per cent.
• Height restrictions, which can bind before FAR does, particularly under an airport funnel zone, and much of Delhi NCR sits under one.
• Setbacks on small plots, which frequently make the permitted ground coverage unreachable.
• Structural and service area. Columns, walls, shafts, staircases and lift cores all consume FAR and produce no saleable or usable space.
• Purchasable FAR, where it exists, which has a cost and a process and is never automatic.

The four checks, in order

1. What is the land use classification of this plot, under the plan currently in force? Not the draft. Under MPD-2021 in Delhi.
2. What are the FAR, ground coverage, setback and height limits for that classification, at this plot size?
3. What is FAR-free here, and what is not? Basement, stilt, services, mumty. Get it in writing.
4. Is the site under an airport height zone, a heritage or ridge regulation, or any other overlay?

Four questions. A day's work. And it is the difference between designing a building and designing a building that has to be redrawn.

We have been shown schemes designed to a FAR the plot never had, by people who had spent real money getting there. It is the most avoidable expensive mistake in Indian practice.
