What is the Difference Between FSI and FAR

What is the Difference Between FSI and FAR?

If you have bought a piece of open plot, and done with the documentation process, and planning to construct on the land then you might be aware of FSI/FAR. Whether you are a builder, a developer, or a land owner who is planning to construct on the open plot FSI/FAR is one of the important documents to be submitted to get permission for further development and construction. It is also vital to get loans and to be submitted along with DTCP, RERA & HDMA documents and certificates.


FSI stands for Floor Space Index. Whereas FAR stands for Floor Area Ratio. Both are one and the same but are used interchangeably. It is a measurement of the size of a building by the ratio of the floor area to its total area. The ratio is mainly used in real estate and construction. It is also a standard for comparing buildings and is used to determine the suitability of a property.

Open plots are less expensive in property costs than apartment buildings and villas

FSI stands for Floor Space Index and is one of the most important parameters to ensure a proper and feasible construction. This is also known as the floor area ratio, which is commonly referred to as FAR. This is the ratio of the total area of ​​a building to the total area of ​​the land on which the building will be erected. The value of FSI is determined by a city’s local authority or the city’s development agency.


FSI / FAR value varies from city to city. DTCP is the body responsible for determining a city’s FSI score. Most Indian cities tend to have lower FSI scores compared to other major cities in the world.

If the FSI in Hyderabad is 2 and the total area of ​​a property is 2,000 square feet, then the total area of ​​coverage or built-up area for the structure is 2 by 2,000 square feet. This clearly means that a developer could very well build a building with a total area of ​​4,000 square feet. FSI serves as a development monitoring tool to monitor the diverse dynamic growth patterns of metropolises


Floor area ratio (FAR)


FAR is important to real estate development because it is a measure of density. This means that a higher value indicates a higher density construction. FAR is also an indicator of the total number of floors of a building. A higher value is not always a good thing, as it can lead to higher costs for firefighting and environment clearance.


The floor area ratio (FAR) is also known as the floor space index (FSI). The formula used to calculate the floor area ratio is usually based on the National Building Code of India. FSI is usually set at the municipal corporation level, depending on the locality.

FAR is an important determinant of development in India. Developers usually request for higher FAR. This allows them to build more units and more floor space. A higher FAR leads to a higher property price. FAR is also important because it helps in determining the height of a building. A higher value of FAR indicates that a building is taller than a similar building.


The floor space index is important because it helps control urban density. The average FSI value maintains the ratio of open space to build space. This helps in keeping city resources in good condition.


FAR (Floor Area Ratio) is a parameter that defines the maximum permissible floor area in a plot. It is calculated based on several factors, including the size of the plot, the width of the road, the plot’s function, and the availability of amenities in the area.  FAR is a value that is used by city planners to establish the maximum permissible floor area. It is used to control the size of urban space, as well as the density of the city. FAR is used in many cities to limit growth patterns. It is also used to promote development in areas with good infrastructure.


The new regulations will also allow property owners to construct structures with a higher FAR ratio, as well as taller buildings. These structures may also be built along Metro corridors. The government hopes this new policy will help with infrastructure development and vertical growth.


The government compensates builders for the redevelopment of slums and for making common recreational areas. This compensation will be an immediate benefit to developers who have signed development agreements. They will be able to focus on residential projects. FSI (floor area ratio) is an important parameter in construction. It is a ratio of the total floor area of a building to the total area of a plot. FSI value varies from city to city.



The floor area ratio is used by the construction industry to divide the land. The building may be a single-storey or a multi-storey building. The FSI value of a multi-storey building depends on the location, size of the building, and the type of building.


The Floor Area Ratio value is determined by the Development Control Regulations of the city. It ensures that there is sufficient space available for open space and built-up space. It also helps in maintaining a balance between sustained growth and development.


The FSI value for industrial buildings is 1.5, while it is 3.5 for residential buildings. For commercial buildings, the FAR is 4.5. The Floor Area Ratio value for group housing projects is 2.75. It is also allowed to go up to 5.25. The construction of commercial and residential buildings has been increased to allow for greater vertical growth.

Final word

The Floor Area Ratio value for residential and commercial buildings will be based on the proximity to metro stations. It will also depend on the development strategy of the city. The increase in FAR will benefit new projects and existing ones. Moreover, it will also reduce property prices in the city.
