Floor Area Ratio (FAR) calculation for plot in Delhi As per local Building Bye Laws

Step 1: Check the Floor area ratio (FAR) for your plot in Delhi from the table below. If you have the plot size in sq. yards then make sure to convert it to sq. m by multiplying it by 0.83. The table shown below is only applicable for plots in Delhi.

Area of Delhi Plot
(sq. meter)
Max. Ground
Coverage %
FAR
No. of Dwelling
Units
Below 3290*3503
Above 32 to 5090*3503
Above 50 to 10090*3504
Above 100 to 25075**300**4
Above 250 to 750752256
Above 750 to 1000502509
Above 1000 to 1500502009
Above 1500 to 22505020012
Above 2250 to 30005020015
Above 3000 to 37505020018
Above 37505020021

Step 2: To take an example, say, your plot size is 300 sq. yards. Convert 300 sq. yards to sq. meters by multiplying it by 0.83. After conversion 300 sq. yards comes out to be 250 sq. meters.

For a 250 sq. meters plot in Delhi the FAR = 300 (as checked from the table).

FAR = (Total area of all floors * 100)/ Plot Area

Therefore, Total area of all floors = (FAR*Plot Area)/100

Total area of all floors for 300 sq. yards = (300*300*9)/100 = 8100 sq. ft.

(Factor of 9 has been used to convert plot size from sq. yards to sq. ft.)

Step 3: If you are planning to consume the full FAR of your plot in Delhi then according to the Delhi Bye Laws you can only build 4 floors. Therefore the per floor coverage area comes out to be 8100/4 = 2025 sq. ft.

Note: Balconies, Stilt Parking, Basement, Lift Shaft & Mumty are excluded from Floor area ratio (FAR) calculations. This list is not exhaustive and certain areas may get added during finalisation of drawings

Practical application of FAR

The most practical way of defining the concept of Floor Area Ratio (FAR) is through an example. FAR of 100 means that as a homeowner you can build a one story building on your plot or a two story building on half your plot. FAR of 200 means that you can build a two story building on your plot or a four story building over half of your plot, and so on.

To continue from our previous example, if you have a 300 sq. yard (250 sq. m) plot in Delhi then the FAR (as checked from the table) comes out to be 300. That means that you can build 3 floors with 100% of the area, i.e. 2691 sq. ft (250 sq. m) or 4 floors with ¾ (75%) of the area, i.e. approx 2025 sq. ft. (187.5 sq. m).

How does defining the FAR of a city benefit its citizens?

Every city is just like a structure and therefore is constrained by the capacity it can withstand. If you go beyond this capacity then it can lead to various issues. FAR defines this load bearing capacity for a city to maintain general well being of the citizens based on a lot of factors such as ability to cope with natural disasters, etc.
