Delhi Building Bye Laws

1. Ground Coverage in Delhi

The portion of the building within the outer surface of the structural wall/ column/ slab measured at ground level excluding the projection/ balcony/ canopy/ porch/ void/ shaft permitted free from FAR and cladding/curtain wall upto 150mm shall be considered as ground coverage. In common words, the area of ground you can cover on your plot is called ground coverage.

2. FAR in Delhi

For a common man FAR is the floor area ratio between the floor area and the plot area. How much you could build on your plot in terms of area considering your plot area and size. To make the FAR calculations easy for you, we have created a FAR Calculator for Delhi. Enter your plot details and get the results in a matter of seconds.

FAR : Te quotient obtained by dividing the total covered area (plinth area) on all floors multiplied by 100 by the area of the plot.

FAR = Total covered area of all floors x 100 / Plot area

For eg:  On a 251 sqm plot your FAR would be 300 hence what you can build will be a total of (251 x 300 )/100 = 753 sqm as total on all floors. You have a choice to divide it to 4 floors as permitted in Delhi or as you like.

EXCLUSIONS:

The following shall not be included in covered area for FAR and Ground Coverage calculations:-

      1. Machine room for lift on top floor as required for the lift machine installation.
      2. Rockery, lift/ lift well, escalator/travelator well and well structures, plant nursery, water pool, swimming pool at any level (if uncovered), platform around a tree, tank, fountain, bench, chabutra with open top and / or unenclosed sides by walls, open ramps, compound wall, gate, slide swing door, fire staircase, fire towers, refuse area, fire control room,  overhead water tank on top of building/open shafts, cooling towers as per fire norms. Fire tender movement shall be unhindered.
      3. Mumty over staircase on top floor maximum 3m height.
      4. Culvert on Municipal drains.
      5. Watch and ward cabins of total area not more than 4.5 sqm and 6sqm with W.C each at entry and exit only, within the property line. Porta cabins for guard room are permitted within the plot line in residential plots of size minimum 200 sqm and above.
      6. Entrance porch, canopies and balconies.
      7. All pergolas at any floor level not exceeding 20% of Ground Coverage.
      8. For Residential Plotted development: Balcony to be provided within the plot line to the max width of 1.5 m free from FAR. Wrap around continuous balconies will be allowed as long as their area does not exceed 40% of the total open area.
      9. Basement is not to be counted in FAR if used for parking, household storage and services.
      10. Passageway/ corridor constructed more than the prescribed /permissible limit should not be counted towards FAR calculations.
      11. One toilet on terrace having a maximum of 2.2 m height shall be permitted subject to condition that the area of toilet is maximum 4 sq. m and not to be counted in FAR and towards height of buildings.
      12. The total coverage and FAR permissible in any plot in a category, shall not be less than that permissible and available to the largest plot in the next lower category.
      13. FAR shall be allowed with maximum size of servant quarter as 25 sq.m and if larger in size would be counted as a full dwelling unit.
      14. Maximum ground coverage, FAR, number of dwelling units for different size of residential plots shall be as per the following table:

      2. FAR shall be allowed with maximum size of servant quarter as 25 sq.m and if larger in size would be counted as a full dwelling unit.

3. SETBACK IN DELHI

The area in your plot on the front rear or sides depending on your plot size, that you leave for  light ,ventilation and services like connectivity to municipal drains etc is called your plot setback. It is defined as   

      1.  An area between the plot boundary and the setback line, size of which is defined as per the provisions of MPD. 
      2. Strip of land permanently left open for drainage purposes not to be used as an access way and is not a street or be included as a part of setbacks.

Set Back Line:  A line usually parallel to the plot boundaries or center line of a road and laid down in each case by the Authority or as per recommendations of Master/Zonal Plan, beyond which nothing can be constructed towards the plot boundaries, excepting with the permission of the Authority.

The minimum setbacks in Delhi shall be as given in the following table:

S.NO. Plot Size (Sq.m.) Front Rear Side(1) Side(2)
1. Below 100 0 0 0 0
2. Above 100 and upto 250 3 0 0 0
3. Above 250 and upto 500 3 3 3 0
4. Above 500 and upto 2000 6 3 3 3
5. Above 2000 and upto 10000 9 6 6 6
6. Above 10000 15 9 9 9

In case the permissible coverage is not achieved with the above mentioned setbacks in a plot, the setbacks of the preceding category may be allowed. Example On a 300 sq yard /251 sqm plot you could choose the setbacks of your preceding category i.e. only leave a front setback of 3 meters if your ground coverage is not being met while taking full FAR for that category.

In case of a corner plot the road width on which the plot abuts will be considered as the side where the setbacks will be. The higher road width will fetch the setback. In case the road width on both sides is the same the setback will come on the side which has a larger depth.

FAR Increase in Gurgaon, Haryana 2019 | New FAR by HUDA

Much to the delight of plot owners in Gurgaon, Haryana, HUDA increased the FAR in Gurgaon in 2019. The FAR was increased in Gurgaon, Haryana in September 2019 by the Haryana Shahari Vikas Pradhikaran (HSVP), formerly Haryana Urban Development Authority (HUDA). On receiving many suggestions by the citizens of Haryana, changes were made by the Department of Town & Country Planning (DTP). These changes are applicable in Private Colonies & Haryana Urban Development Authority (HUDA) Sectors. This is now a part of the Haryana Building By Laws as well.

huda increase far in gurgaon 2019

After the revised 2016 Haryana Building By Laws, additional FAR was allowed on plots upon payment of charges as approved by the government. This Purchasable FAR was again increased in September, 2019. Before we explain the FAR Increase in Gurgaon, let us first understand what is FAR. If you would like to save your time and calculate FAR in Gurgaon in a matter of seconds, please click the link.

What is FAR?

FAR is the floor area ratio between the floor area and the plot area, meaning how much you can build on your plot in terms of area considering your plot area and size. The quotient is obtained by total covered area (plinth area) on all floors multiplied by 100, divided by the area of the plot.

FAR = Total covered area of all floors x 100/ Plot area

New Increased FAR in Gurgaon, Haryana

To understand the calculations as per new FAR, let us take an example of a 200 sq. yards plot. The total FAR is a sum of Max Free FAR+Max Purchasable FAR.

Convert 200 sq. yd. to sq. m. by multiplying it by 0.836 and the result is 167 sq. m.

For a 167 sq. m. plot in Gurgaon, the Free/Real FAR is 145 and the Purchasable FAR is 119. Hence the New Total FAR is 264.

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 200 sq.yd. (167sq. m.) in Gurgaon = (264*167)/100 = 441.46 sq.m.

Total area of all floors in sq. ft. = 4751.84 sq. ft.

If you are planning to consume the full FAR of your plot in Gurgaon then according to the Gurgaon By Laws, you can build a maximum of 4 floors. Therefore the per floor coverage area comes out to be 4751.84/4 = 1188 sq. ft.

If you would like to save your time and calculate FAR in Gurgaon in a matter of seconds, please click the link.

Below table has been created in accordance with the new changes of FAR in Haryana.

 

Plot Size in Sqm Ground Coverage% Normal FAR Purchasable FAR Total
1-75 66 165 99 264
76-100 66 165 99 264
101-150 66 145 119 264
151-200 66 145 119 264
201-250 66 145 119 264
251-350 60 125 115 240
351-500 60 120 120 240
501 and above 60 100 140 240

To make things easier for you, we have created an FAR Calculator which will help the people of Gurgaon and Faridabad (Haryana) in calculating the FAR in just 2 steps.

HSVP/HUDA Clarifies Some More Points

1. Increase in FAR will have no change in the number of dwelling units allowed on residential plots.

2. For all the constructed/under construction plots, the owner will have the option to purchase additional FAR. In such cases, HSVP/HUDA will not insist on purchase of maximum allowed purchasable FAR.

The option of partial purchasable FAR will not be available in case of fresh sanction of plans & in cases where construction is being done after demolishing the existing structure.

3. The zoning plans/architectural controls in licenced colonies will be suitably revised.

4. No further composition of zoning violation beyond the maximum permissible covered area and FAR shall be allowed in case the allottee purchases additional FAR. However, in cases where additional FAR is not being purchased, the existing composition policy shall continue. In case of an existing building on a plot where extra area has already been compounded as per policy, the same will be counted in the maximum permissible ground coverage & FAR being allowed as purchasable FAR. Though, no cost will be charged for the already compounded area.

The above details and points have been taken from “Town & Country Planning Department, Haryana

However, there is a catch 22 situation here as one may never be able to achieve complete FAR unless he/she changes the ground coverage on plots. Hence, we have requested the department to look into avenues which could help people achieve complete FAR.

Calculate New FAR in Gurgaon and Faridabad, Haryana.

In addition, if you want to avoid all these complications, you can use our FAR Calculator which will help you to find the FAR in Gurgaon and FAR in Faridabad (Haryana).

Violation of Building Bye Laws for Short Term Gains

With land being at such a premium, it has become common practice for builder floor home constructions around Delhi and Gurgaon to violate some building bye-laws to allow for more coverage to increase the selling price. Most clients are either unaware of this or turn a blind eye to it seeing only what they perceive as the immediate monetary and space benefit. However, one must realise, that bye-laws are developed first and foremost for the safety of the inhabitant and the city.

Some areas where builders and contractors typically violate bye-laws:

– Ignoring setbacks to increase plot coverage or basement size.
– Shaft dimensions lesser than that stipulated in bye-laws.
– Using of basement or stilt level for unauthorised office spaces, servant’s quarters and other habitable spaces.

Building Bye Laws are designed to safeguard the occupants from hazards like fire, flooding, earthquakes, poor light, ventilation, indoor air quality and so on. Violations of these bye-laws compromise the building’s safety standards and put its occupants at risk. We must also realise, some rules like minimum balcony width of five feet and minimum ventilation shaft dimensions are for improving the quality of the space for the user. The bye-laws are not unreasonable – recent revisions in the Delhi bye-laws have allowed bathrooms on stilt and terrace levels to meet utility needs. A good design is always the better solution – it will ensure the best utilization of your available space minimizing negative spaces like long corridors and poorly lit rooms.

While ignorance of bye-laws definitely puts the occupants of the building at risk, it also creates other problems. Many of these buildings do not get a completion certificate as the completed building is different from the sanctioned building. This creates problems as potential buyers of builder floor home constructions do not want the litigation problems that could arise out of purchase of such properties. Reselling in the future also becomes a hassle for the same reasons. Sometimes completion certificates are acquired by means of hefty bribes but there too there is no guarantee of peace of mind.

At the end of the day, the risks associated with violation of bye-laws are too great a gamble for some extra benefits that comes hand-in-hand with legal troubles. As a property owner of a collaboration project, clean properties complying with the bye-laws give you both peace of mind and a better premium than a property with possible litigation issues. Any legal issues post-completion will be faced by you and not the builder. So think long-term and always opt for builders like Prithu that will give you the best designs within the framework of the building bye-laws to ensure a safe and hassle-free home for you and your loved ones.

All You Need to Know About Building Bye Laws

building bye laws, building bye laws india

Building a house of your own is everyone’s dream. It is a simple thing to draw up a plan of your dream house, but constructing it is an entirely different game. In order to get the green signal to start construction, you need to ensure that your house plan follows the building-bye-laws of the locality. These laws are a set of rules and regulations drawn up by the government of every country, to assure a systematic and disciplined growth of the town or city.

Without these laws, people will tend to construct buildings any which way, leading to haphazard development and confusion in the future. Following these laws will also ensure the maximum utilisation of available space and safety of the people living in and around the house.

It is to be noted that building by-laws are unique to every region. What may be applicable in a village may not be practical or possible in the city. So, before you draw up a blueprint for your dream home, make a study of the building by-laws applicable in your region. (When you partner with Prithu Homes to make your dream home all of these by-laws are handled by the compliance team and the entire process is made hassle free for you) For your reference, we have compiled a list of the general points covered in the building bye laws.

Floor Area Ratio (FAR) or Floor Space Index (FSI)

Every city has a limited capacity in terms of resources and infrastructure. In order to avoid additional stress beyond the capacity of the city, a Floor Area Ratio (FAR) is calculated. It is also termed as Floor Space Ratio (FSR) or Floor Space Index (FSI). It is simply formulated as the ratio of total covered area (actual area) of all the floors to the total plot area.

FAR = Total area of all floors/ Plot Area

Permissible FAR and Maximum Height as defined by HUDA (Haryana Urban Development Authority)

Area of Site / Category of Plot Maximum Permissible FAR
1 Marla = 25 Sq. Yards

1 Kanal = 20 Marla

6 Marla 2.64
10 Marla 2.64
14 Marla 2.40
1 Kanal 2.40
2 Kanal 2.40

Suppose the builder has got a plot of 1,000 sq m and the permissible FAR, according to development plans is 2.4. He is allowed to construct a building on 2,400 sq m of this plot. It is the ratio of the total floor area of the building compared with the total plot area.

The FAR for every building will differ depending upon its usage, type of construction, the locality and its population, the width and traffic on the street in front, parking facilities, water and drainage facilities, and local fire fighting facilities.

Ground Coverage

The total area covered by the building on the ground floor is known as ground coverage. Keep in mind, if you are constructing a basement, it should not exceed the ground coverage area. Based on restrictions of height and FAR, the ground coverage can be adjusted to get maximum usage of the plot.

The ground coverage area is calculated by dividing the building area with the total plot area. Building area means the floor space of a building when looking down at it from top.

Building Coverage Ratio (BCR) = Building Area / Site Area

Setbacks

A building setback is the open space between the building and the property boundary or lot line. We can construct the house only up to the setback line. This again varies for different types of buildings. For example, a stand-alone building must have more front open space than a row-type building. The setback line is applicable not just in the front, but also around the entire building. The total plot area is another determining factor for the setback line.

Height Restrictions

The height of a building is the vertical distance between the average level of the ground and the topmost point of the building. Remember, if there is a basement to your house, it will not be considered in height measurement. Depending upon the locality and your FAR, there will be a maximum limit to how tall you can construct your house. This is mainly done to ensure your safety; for example, in case there is an airport or high electricity transmission lines in the neighborhood.

As per HUDA (Haryana Urban Development Authority):

Maximum permissible height with a stilt floor is 15 meters from road level.

The basement is the lower storey of a building, constructed below or partly below the ground. Depending upon the locality, there is a restriction to the height of the basement, projected above the average ground level. If the house is built on stilts, the allowed height will again depend upon the locality.
