FSI or FAR in Lucknow 2025

FSI, Floor Space Index, FAR or Floor Area Ratio, in Lucknow, is a major factor to consider while constructing a building since it is the maximum area in a plot to be used for construction.

Whether you’re a builder or an individual in Lucknow wanting to construct a house or any building on a plot of land, you must be aware of the FSI laws of your city. Floor Space Index (FSI), also known as Floor Area Ratio (FAR), is the maximum area in a plot you can use for construction. This value varies with each city; the local municipal authority usually sets the value.

How to Calculate FSI in Lucknow?

The Floor Space Index in Lucknow is calculated as below.

Formula: The total buildup area across different floors/The total area of the plot in sq.m

The constructed area includes all the basic structures, including patios, balconies, basements, and stairways.

The Floor Space Index value in Lucknow also depends on other factors, including:

The type of building
The total size of the plot
The size of the roads surrounding the plot
The availability of essential factors like sewer lines, running water, and power

Importance of FSI

FSI is super important in crowded cities like Lucknow to handle congestion and ensure that the city’s resources are distributed evenly. Most cities want to dedicate a certain percentage of the area to public places like parks and roads. Without FSI restrictions, these cities will get overcrowded with buildings. Floor Space Index in Lucknow also helps control vertical building growths and prevents people from having to fight for amenities like water and electricity.

When the FSI value is high, the plot value is also high. Most people buy plots in high FSI areas to construct commercial or residential structures and rent/lease them out.

Floor Space Index in Lucknow

According to the Lucknow Development Authority (LDA), the average Floor Space Index in Lucknow ranges between 1.25 and 1.5.

Before 2016, the LDA had a minimum plot size requirement of 2000 sq.m to build apartments. Since 2016, though, the minimum plot area requirement has been reduced to 300 sq.m. This has given rise to several smaller residential apartments in the city since then.

Purchasable Floor Area Ratio in Lucknow

Lucknow is, without a doubt, getting more congested, and there is a lack of living space for the growing populace. As a result, the Housing & Urban Planning Department, Uttar Pradesh, has come up with an option of Purchasable Floor Area Ratio. According to this, anyone who wants to construct buildings that spread beyond the acceptable FAR values in that area can purchase extra FAR depending on the location.

The charge for purchasing the extra Floor Space Index in Lucknow is calculated as below.

Charge (C) = Le X P X Rc

Le – additional floor area required (in sq.m) X 100/ Actual FAR

P – Purchasable Factor

Here are the purchasable factor limits for different buildings:

Rc – Current Residential rate of the land decided by the local government authorities

Unitary residential buildings and industrial buildings cannot make use of the purchasable Floor Area Ratio.

Why is FSI Important for Real Estate Developers in Lucknow?

Real estate developers in Lucknow typically favour a higher FSI to increase their profit margin. One way to increase the FSI value is to encourage the emergence of apartments. If the FSI were greater, a real estate developer would undoubtedly build a high-rise structure and sell more homes to customers.

Developers would profit more from the overall urbanisation of developing regions and housing for all schemes, which would also assist in closing the current imbalance between supply and demand for real estate.
