The types of FSI (Floor Space Index) can vary based on the specific land use and zoning regulations in different regions. Generally, the concept of FSI applies across various types of developments including residential, industrial, commercial, and mixed-use areas. However, the specific terms and regulations might differ based on local planning practices and regulations. Here are some common variations that you might find in different types of developments
This is the most common type and refers to the ratio of the total floor area of residential buildings to the size of the land on which they are built. It is used to regulate the density of housing in residential areas.
This type of FSI is applicable to commercial properties, such as retail stores, offices, and other commercial establishments. It governs the amount of floor area that can be constructed for commercial purposes relative to the land area.
Industrial FSI is specific to industrial developments and sets the limit on the floor area that can be used for industrial activities on a given piece of land.
In areas where there’s a mix of different land uses, such as a combination of residential and commercial properties in the same development, mixed-use FSI might be applied. It takes into account the different types of spaces within the development.
In some cases, regulations might include a provision for recreational or open spaces within a development. This type of FSI governs the amount of space that must be reserved for parks, green areas, and other recreational purposes
In areas where old or dilapidated buildings are being redeveloped, there might be special provisions for redevelopment FSI that encourage the replacement of old structures with new ones, potentially allowing for higher densities.
In regions focusing on transit-oriented development, there could be specific FSI guidelines that encourage higher density developments around transit hubs like train stations or bus terminals.
Some regions offer incentives for preserving heritage buildings. Heritage conservation FSI might allow for additional floor area in exchange for the restoration and preservation of historic structures.
In areas with housing affordability challenges, there might be FSI incentives for developers to include a certain percentage of affordable housing units in their projects.
HOW THE ALL TYPES OF FSI CALCULATED FOR DEVELOPMENT IN MAHARASHTRA
In Maharashtra, the calculation of FSI can vary depending on the type of development, the location, and the specific rules set by the government. As of my last knowledge update in September 2021, the calculation of FSI for development in Maharashtra typically involves the following factors
The size of the plot of land plays a significant role in determining the FSI. Generally, smaller plots might have a higher FSI to encourage optimal land use.
The land is divided into different zones (residential, commercial, industrial, etc.), each with its own FSI regulations. The zoning regulations define what kind of development is allowed in a particular area and what the associated FSI limits are.
Industrial aThe location of the plot within a city or municipality can affect the FSI calculation. Areas with better infrastructure and transportation facilities might have higher FSI allowances.SI is specific to industrial developments and sets the limit on the floor area that can be used for industrial activities on a given piece of land.
The width of the adjacent road or street can impact the FSI calculation. Wider roads might lead to higher FSI allowances to accommodate larger buildings.
The type of building (residential, commercial, industrial) and its purpose can influence FSI calculations. For instance, residential buildings might have different FSI calculations than commercial complexes.
In areas where old or dilapidated buildings are being redeveloped, there might be special provisions for redevelopment FSI that encourage the replacement of old structures with new ones, potentially allowing for higher densities.
In some cases, environmental regulations and considerations might influence FSI. For example, areas near sensitive ecological zones might have lower FSI to limit environmental impact.
Some regions offer incentives for preserving heritage buildings. Heritage conservation FSI might allow for additional floor area in exchange for the restoration and preservation of historic structures.
WHAT MEANING OF FUNGIBLE FSI & CALCULATIONS TO USE IN DEVELOPEMENT
“Fungible FSI” refers to the concept of interchangeable or transferable additional Floor Space Index (FSI) within a development project. It allows developers to use the extra FSI allocated for specific purposes, such as amenities, balconies, or open spaces, in a flexible manner. This means that the developer can distribute the additional FSI across various parts of the project based on their requirements, as long as they adhere to the overall development regulations and guidelines.
The idea behind fungible FSI is to provide developers with the freedom to optimize the utilization of the additional floor area while still maintaining the prescribed limits on overall density and construction. This approach can be beneficial in cases where rigid allocation of additional FSI might not align with the project’s design or practical considerations.
Here’s a general outline of how the calculation and use of fungible FSI might work in a development:
Â
1. Calculation of Fungible FSI
The calculation of fungible FSI varies based on local regulations and can be related to factors such as the total built-up area, the percentage of the plot area, and the type of development. Fungible FSI is often calculated as a percentage of the total plot area or built-up area. For instance, if the base FSI is 2.0 and the fungible FSI is 20%, then for every 100 square meters of plot area, the developer can use an additional 20 square meters of FSI for flexible purposes.

2. Allocation of Additional FSI
Once the developer knows the amount of fungible FSI available, they can allocate it to various components of the project that fall within the scope of fungible utilization. This could include balconies, terraces, amenity spaces, and other features that enhance the quality of the development.
3. Submission to Authorities
Depending on local regulations, the developer might need to submit plans or documents to the local planning or building authorities detailing how the fungible FSI will be utilized. These documents typically outline the areas and purposes for which the additional FSI will be used.
4. Monitoring and Compliance
The development process needs to adhere to the approved plans and allocations of fungible FSI. Building inspectors or relevant authorities might monitor the construction to ensure that the utilization of additional FSI aligns with the approved plans.
5. Documentation and Records
It’s important for developers to maintain accurate records and documentation of how the fungible FSI was utilized. This can help during inspections, approvals, and other regulatory processes.
6. Public and Community Benefits
Some jurisdictions might require developers to provide public or community benefits in exchange for using fungible FSI. These benefits could include open spaces, affordable housing units, or contributions to local infrastructure.
It’s important to note that the specific rules and regulations surrounding fungible FSI can vary significantly from one jurisdiction to another. Local building codes, zoning regulations, and planning policies will dictate how fungible FSI is calculated and utilized in a particular development. If you’re a developer looking to use fungible FSI in a project, it’s recommended to consult with local planning authorities or professionals who are familiar with the specific regulations in your area.
