Pre-Construction Checklist in Bangalore

The Ultimate Checklist Before Starting House Construction in Bangalore

Starting a residential project in Bangalore is an exciting milestone, but proper preparation determines long-term success. With the 2026 transition to the Greater Bengaluru Authority (GBA), building plan approvals and compliance processes have become more digital and structured. Whether you are constructing an independent duplex in Malleshwaram or a villa in the suburbs, clearing legal, financial, and technical requirements is essential before excavation begins.

A complete pre-construction checklist prevents costly rework and ensures eligibility for permanent BESCOM and BWSSB utility connections. From verifying the Mother Deed to conducting a professional geotechnical soil test, following each step carefully guarantees a smooth and legally compliant construction journey.

Legal & Document Verification (The Paperwork Trail)

Before construction, your land must be legally ready for development in Bangalore.

  • E-Khata & Mother Deed: Ensure you possess a valid digital E-Khata and verify the Mother Deed history for at least 30 years.
  • Encumbrance Certificate (EC): Obtain 15–30 years EC to confirm the property has no financial liabilities.
  • Updated Tax Receipts: Clear property taxes up to the 2025-26 financial year.
  • DC Conversion: Verify residential conversion for previously agricultural land.

Technical Surveys and Soil Investigation

Never begin construction without completing essential technical checks.

  • Professional Land Survey: Mark accurate boundaries to avoid encroachment issues in areas like Malleshwaram.
  • Geotechnical Soil Testing (SPT): Determine soil load-bearing capacity to optimize foundation and RCC structure design.
  • Topography & Leveling: Assess plot slope for effective drainage and rainwater harvesting planning.

2026 Building Plan Sanctions & Approvals

Understanding the latest GBA and BBMP building approval rules is critical.

  • Nambike Nakshe: For plots up to 50x80 ft in Malleshwaram, use this trust-based approval system.
  • Setback Compliance: Ensure adherence to updated GBA setback norms.
  • Utility NOCs: Obtain No Objection Certificates from BESCOM and BWSSB.
  • Borewell Permission: Secure Ground Water Authority approval before drilling.

Financial Planning and Builder Contracts

Finalizing your budget and legal agreements is the last step before excavation.

  • Itemized BOQ: Demand a detailed Bill of Quantities specifying material brands and grades.
  • Contingency Fund: Reserve at least 10% of your total budget for unforeseen expenses.
  • Construction Agreement: Include milestone-based payments, delay penalties, and a 5–10 year structural warranty.

Frequently Asked Questions (FAQs)

Can I start construction with a B-Khata in Bangalore in 2026?

No. BBMP does not issue building plan sanctions for B-Khata properties. Conversion to A-Khata or applicable regularization schemes is required before starting house construction.

Is a soil test mandatory for a G+2 house in Malleshwaram?

While not always legally mandatory, soil testing is highly recommended. Malleshwaram has varied soil conditions, and a proper test ensures safe and cost-efficient foundation design.

How much does a building plan sanction cost in Bangalore?

For a standard 30x40 residential plot, official sanction fees typically range between ₹30,000 to ₹80,000 depending on total built-up area and approval type.
