Fungible FSI - Meaning, Calculation, Importance & More
By Investoxpert | 19 Dec 2023 | Real Estate

Fungible FSI (Floor Space Index) has become a key idea in the Indian real estate sector, enabling developers to construct more stories over the government-mandated maximum allowable limit. The maximum floor area that can be built on a specific land parcel is known as the FSI limit, and it varies based on the region. The FSI limit establishes a building's built-up area, which in turn determines how many stories can be constructed on a piece of land.
What Is Fungible FSI?
With fungible FSI, builders can add more stories to their building beyond the FSI cap in exchange for a premium that is determined by the local ready-to-assemble rates. However, using the Fungible Floor Space Index is subject to government rules, and using this mechanism requires paying the required premiums.
Developers have embraced the idea of Fungible FSI since it allows them to add more stories without going over the government's FSI cap. It also enables them to increase earnings and utilize the entire property parcel.

What Is Fungible FSI In Real Estate?
The extra floor area built by a developer above the maximum allowable FSI limit established by the local governing bodies is known as fungible FSI. The built-up area of the structure increases as a result of this growth that goes over the limit; this is referred to as Fungible FSI or Premium FSI. In order to implement this kind of development, builders must pay charges and adhere to laws in order to acquire additional space from the local authorities.

What Is the Fungible FSI Limit ?
The standard states that the Fungible FSI in residential properties cannot be more than 35 percent of the floor area; in commercial and industrial developments, it can be up to 20 percent of the floor area. Any building that exceeds the Fungible floor space index limit that was purchased is considered illegal, and the builders risk severe repercussions such as large fines, project demolition, or jail time.
It is significant to remember that the local government regulates the use of Fungible FSI, and builders are required to adhere to the established standards and guidelines. Developers are now able to build more efficient structures and make the most use of available land while still adhering to laws thanks to the Fungible Floor Space Index.

What Is Fungible FSI For Redevelopment?
The fungible FSI shouldn't be more than 35% of the floor area in residential buildings and 20% of the floor area in developments for businesses and industry. Any additional space that is purchased is illegal, and the builder may be subject to harsh penalties, project demolition, or even jail time.
How Is the Fungible FSI Calculation Done?
For the road adjacent to the property to qualify for the fungible FSI, it must be at least thirty feet wide. Based on the widths of surrounding roadways, the fungible floor space index is broken down as follows.
In the event that the builder were to obtain 2,000 square feet of property with an FSI of two, along with a 35-foot-wide neighboring road, they would be qualified to obtain 20% additional floor space as fungible FSI.
Therefore, in this instance, the additional built-up area would be 20% larger than the floor space that the builder might get by using the fungible floor space index.
Built-up Area x Fungible FSI
(2,000 sq ft x 2) x 20/100 = 800 sq ft
Total floor space allowed = 4,000 + 800 = 4,800 sq ft
The builder has the permission to build a maximum of 4,800 sq ft of floor space.
The construction plan and building type are two examples of the variables that affect the fungible FSI laws. Visit the State government's official website to learn more about the most recent FSI and fungible floor space index rules in the selected location.
