What is FSI/FSR?

FSI (Floor Space Index) or FSR (Floor Space Ratio) is a key real estate development regulation that defines how much construction is allowed on a given plot of land. It represents the ratio between the total built-up area and the size of the plot. In simple terms, it controls how densely a property can be developed.

Understanding FSI/FSR in Real Estate

FSI or FSR determines the maximum permissible built-up area on a land parcel. Municipal authorities and urban development bodies set these limits based on city planning rules.

Basic Formula:

FSI = Total Built-up Area ÷ Plot Area

Example:

If FSI is 2, a 1,000 sq. ft. plot can have up to 2,000 sq. ft. of built-up space.

Key Components of FSI

  1. Plot Area

    • The total land available for construction
    • Measured in square feet or square meters
  2. Built-up Area

    • Includes residential or commercial floors
    • Includes internal walls and usable space
    • Includes covered balconies (as per local rules)
  3. Permissible FSI

    • Defined by local municipal authorities
    • Varies based on location, zone, and infrastructure capacity

FSI/FSR is a crucial regulation in real estate that defines how much construction is allowed on a land parcel. It directly impacts building size, property value, and urban development patterns.
