Building Plan Approval in Bengaluru: Full Process Explained

What is Building Plan Approval?

Building Plan Approval is the official permission granted by the local development authority (BBMP, BDA, BMRDA, or Panchayat) allowing you to begin construction. Your proposed construction must comply with zoning laws, setbacks, height restrictions, Floor Area Ratio (FAR), building codes, and safety regulations.

Without this approval, any construction activity is considered unauthorized and could result in penalties, demolition notices, or denial of occupancy certificates.

Who Needs Building Plan Approval?

  • Homeowners constructing independent houses
  • Developers building apartments or commercial complexes
  • Layout owners converting agricultural land for plotted developments
  • Individuals modifying or expanding existing structures

In Bengaluru, the approving authority depends on the property’s location:

  • BBMP for core city areas
  • BDA/BMRDA for extended zones
  • Gram Panchayat/Town Planning for outskirts

Key Documents Required

  • Khata certificate or mutation extract
  • RTC or land record
  • Survey sketch / village map

All drawings must follow National Building Code standards and local bye-laws.
