FSI In Thane 2025: Regulations, Calculation And Everything You Need To Know

What Is FSI in Thane? How Does It Affect The Value of Property?

FSI stands for Floor Space Index, which is a measure of the total area of a building that can be constructed on a given plot of land.

In Thane, FSI is regulated by the local government and is used to determine the maximum permissible construction on a plot of land.

FSI in Thane ranges from 2-4 for the residential sector. 

FSI affects the value of property in Thane in several ways. 

• Firstly, a higher FSI allows for greater construction in the city and can increase the usable area of a building, thereby increasing its value. 
• Secondly, a higher FSI often leads to the development of better infrastructure, such as improved roads, water supply, and public transport, which can increase the value of property in the area. 
• Additionally, a lower FSI may limit the potential for development and can lead to higher demand for existing properties, driving up their value.

It is important to note that FSI regulations can be complex and vary from location to location. 

Importance of FSI in Thane

FSI is an important factor in the development of real estate in Thane. 

FSI regulates the maximum permissible construction on a plot of land and is determined by the local government. 

Here are some of the key reasons why FSI is important in Thane:

Optimal utilization of land: FSI ensures that the available land is utilized to its fullest potential. By setting limits on the amount of construction that can be done on a plot of land, FSI helps to ensure that land is not wasted or underutilized.

Control over urbanization: FSI is used by the government to control the rate and scale of urbanization in Thane. By regulating the amount of construction that can be done, FSI helps to maintain a balance between development and environmental concerns.

Promotes affordable housing: FSI can be used to promote affordable housing by allowing for the construction of smaller units in the same amount of space. This can help to meet the housing needs of low-income families and individuals.

Improved infrastructure: FSI regulations often require developers to provide infrastructure such as roads, water supply, and public transport. This can lead to the development of better infrastructure in Thane, which can benefit the local community.

What are the New FSI Rules in Thane 2025?

Last December, the state passed the Uniform DCPR for the entirety of the State, excluding Mumbai. Eknath Shinde, the urban development minister, published the revisions to this Uniform DCPR in Thane on Friday.

Before last year, the permitted Floor Space Index (FSI) for old structures was 50% but is now 10%. Since the amendment, the initial 50% FSI has been reintroduced. 

High-rises can now be built in old Thane because the restriction on building height has been raised from 24 to 70 metres.

Due to the need for more FSI or TDR for crowded neighbourhoods, the majority of redevelopment projects in this section of the city have stopped. This FSI is not allowed due to the roads being only 6 to 8 metres wide. The proposed amendment eliminates the limit of 2 FSI and allows for FSI up to 4.16.

How To Calculate FSI In Thane?

In Thane, the calculation of FSI is governed by the Development Control Regulations (DCR) set by the Thane Municipal Corporation (TMC).

To calculate FSI in Thane, you will need to consider the following factors:

The total area of the plot of land

The permissible FSI as per the DCR set by the TMC

The built-up area of each floor

The formula to calculate FSI in Thane is:

FSI = Total built-up area of all floors / Total area of the plot of land

For example, let’s say the total area of the plot of land is 1000 square meters, the permissible FSI is 2, and the built-up area of each floor is 500 square meters.

Then the FSI will be calculated as follows:

Total built-up area of all floors = (500 sq.m x 2) = 1000 sq.m

FSI = 1000 sq.m / 1000 sq.m = 1

Therefore, the FSI for this example is 1.

What Is FSI For Residential Buildings In Thane?

The Floor Space Index (FSI) for residential buildings in Thane depends on various factors such as the type of property, location, and the Development Control Regulations (DCR) set by the Thane Municipal Corporation (TMC).

As per the current DCR in Thane, the permissible FSI for residential buildings is up to 2. However, this can go up to 3-4 depending on the location and type of residential property.

FSI in Thane for the redevelopment project is 2.5 this can vary up to 4 as per a recent amendment. 

Premium FSI charges in Thane

The government will levy a premium fee known as the FSI Premium if you want to enhance the permitted FSI (Floor Space Index).

If the roadway next to the building is 30 to 40 feet wide then premium FSI is 20%. In a similar vein, if your property is close to a 40–60 ft wide road, you have to pay a 30% of premium FSI and the Premium FSI is 40% for lands that are adjoined by a roadway that is longer than 60 feet.

What is Permissible FSI in Thane

Permissible FSI (Floor Space Index) in Thane is the maximum ratio of the built-up area of a building to the area of the plot of land on which the building is constructed.

As per the current DCR in Thane, the permissible FSI for different types of properties are as follows:

Residential buildings: up to 2-5 FSI

Commercial buildings: up to 3 FSI

Industrial buildings: up to 1 FSI

IT/ITES buildings: up to 3 FSI

Impact of FSI on Thane’s Real Estate Landscape

FSI (Floor Space Index) is an important factor that affects the real estate landscape of Thane, as it determines the maximum built-up area that can be constructed on a given plot of land.

Here are some of the ways in which FSI impacts Thane’s real estate:

Increase in building height: With a higher FSI, developers can construct taller buildings, which can help increase the supply of housing and commercial space in areas where land is scarce or expensive.

Increase in property values: Higher FSI allows for greater construction, which can increase the overall value of a property. As a result, properties with higher FSI are generally more expensive than those with lower FSI.

More development opportunities: Developers may be more interested in acquiring land with higher FSI, as it allows for more construction and higher returns on investment. This can lead to more development opportunities in areas with higher FSI.

Impact on infrastructure: With more construction and development, there may be a strain on infrastructure such as roads, water supply, and sewage systems. It is important for the government to ensure that infrastructure keeps pace with development.

Impact on the environment: With increased construction and development, there may be a greater impact on the environment. This can include loss of green spaces, increase in traffic congestion and pollution, and strain on natural resources.
