Updated 21 October 2026. We re-read the GBA launch reports, Deccan Herald's 28 September editorial and its 2024 reports on the first Nambike Nakshe. Pages ranking for this search mostly repeat the 30-minute headline. This one also says what has not been published (the pilot areas and the fees), separates the 2024 scheme's rules from the 2026 version, and explains how the new joint-owner sub-division service on eAasthi 2.0 feeds into it.

Who qualifies for 30-minute approval

  • Use: residential buildings. Commercial buildings and larger developments are to be looked at in later phases (Deccan Herald, 19 September 2026).
  • Site size: up to 50x80 ft, that is 4,000 sq ft or about 372 sq m (our conversion).
  • Units: up to four dwelling units (The Bengaluru Live, 19 September 2026).
  • Plan: must comply with the applicable town-planning regulations. A plan with violations is not auto-approved.
  • Submission: through a qualified architect. Owners do not file it themselves.
  • Area: pilot areas only for now. The GBA said it would review the pilot before extending it across its jurisdiction (Deccan Herald, 19 September 2026). We found no public list of pilot areas on 21 October 2026, so ask your architect or the zonal town-planning office whether your ward is covered.

How Nambike Nakshe 2.0 works: step by step

  • 1. Your architect or engineer uploads the building plan online.
  • 2. They enter the property's e-Khata number. The system fetches the basic ownership details itself, so the khata and several property documents need not be uploaded separately (Deccan Herald, 19 September 2026).
  • 3. The software checks the plan for zonal violations.
  • 4. If none are found, the approval is issued in about 30 minutes.
  • 5. You download the approval.
  • The GBA calls the model 'Trust, but Verify': owners and architects are responsible for a compliant plan, and the minister warned of stringent penalties for deliberate violations or misuse (The Bengaluru Live, 19 September 2026).

Documents to keep ready

The GBA has said only that the e-Khata number pulls ownership data automatically. We did not find a published 2.0 document list. Under the 2024 scheme, owners supplied plot ownership documents, revenue records, the plot's guidance value, approach-road width and present site conditions (Deccan Herald, 3 September 2024). Keep these to hand:

  • Your A-eKhata number, with names and area matching the sale deed.
  • The registered sale or partition deed.
  • Encumbrance certificates for the full period.
  • The latest property-tax receipt.
  • Measured site details: dimensions, road width in front, and any drain, lake or railway line nearby.
  • The architect's drawings, prepared to the zoning rules for your plot.

What does building plan approval cost in Bangalore?

The GBA has not published a fee schedule or calculator for Nambike Nakshe 2.0 that we could find on 21 October 2026, and we will not guess one. Under the 2024 version, the software generated a fee challan after the automated check, and applicants had up to 45 days to pay online before the provisional licence was issued (Deccan Herald, 12 March 2024). Whether that sequence carries into 2.0 has not been stated. Ask your architect for the fee shown by the system before you commit, and budget separately for the architect's own fee.

What changed and when

  • 11 March 2024: BBMP launches the first Nambike Nakshe in RR Nagar and Dasarahalli zones, for houses up to four floors on plots under 50x80 ft, filed through an empanelled engineer or architect (Deccan Herald, 12 March 2024).
  • 2024 mechanics (version 1 only): documents were shared with the Karnataka State Remote Sensing Applications Centre to check buffers from drains, lakes, heritage buildings and railway lines; a provisional plan not acted on within 15 days was treated as deemed approved (Deccan Herald, 12 March 2024).
  • 2 September 2024: extended to all eight BBMP zones; BBMP was clearing about 10,000 plan approvals a year (Deccan Herald, 3 September 2024).
  • 19 September 2026: GBA launches Nambike Nakshe 2.0 as a pilot, with e-Khata auto-fetch and approval in about 30 minutes (Deccan Herald, 19 September 2026).
  • 17 October 2026: joint owners can now split an A-eKhata plot online; each new owner can then seek a building plan for their part (Deccan Herald, 17 October 2026).
  • Do not assume the 2024 buffer checks, 45-day window or deemed approval apply to 2.0; the GBA has not said so.

After approval: inspections and the Occupancy Certificate

A fast sanction is the start, not the end. Deccan Herald's editorial (28 September 2026) argued that every auto-approved plan should be linked to stage inspections and that compliance should be a condition for the Occupancy Certificate, with a QR code at each site showing the sanctioned plan. These are proposals, not rules. In 2024 officials said engineers would visit sites to check deviations during construction (Deccan Herald, 3 September 2024).

For an owner, the practical point is simple: build exactly to the approved plan. Deviations can surface at OC stage, at resale and at the bank.

Sub-divided plots, B-khata and buying a plot to build

Mistakes to avoid

  • Drawing a plan to your wishes and hoping the software passes it. Design to the zoning rules from the start.
  • Assuming your ward is in the pilot.
  • Using an e-Khata with errors in name or area. Correct it before the architect files.
  • Building beyond the sanction. The trust model comes with penalties for deliberate violations.
