Bangalore, known for its rapid urbanization, has strict building regulations to control infrastructure growth. Whether you are planning to construct a residential house, commercial building, or apartment, understanding the BBMP building bylaws is crucial. In this guide, we will explore the maximum floors allowed in Bangalore based on plot size, zoning, and regulations.
Understanding BBMP Building Bylaws for Floor Limits
The Bruhat Bengaluru Mahanagara Palike (BBMP) sets guidelines for construction in Bangalore. The number of floors you can build depends on various factors, including Floor Area Ratio (FAR), road width, and zoning regulations.
What is Floor Area Ratio (FAR)?
FAR determines how much built-up area you can have on your plot.
FAR Calculation Formula:
FAR = Total Built-up Area / Plot Area
Higher FAR values mean you can build more floors. It varies based on location and land usage.
