Commercial Property Due Diligence Checklist: Bangalore Guide

A complete commercial real estate due diligence checklist for Bengaluru Karnataka legal title, EC, RERA, OC, zoning, financial, environmental, and operational checks before buying.

Quick Summary: (TL; DR)

Commercial real estate due diligence is the systematic verification of a commercial property's legal, financial, physical, and regulatory status before completing a purchase. For Bengaluru commercial properties (offices, retail spaces, industrial sheds, warehouses), due diligence must cover: title verification (EC + 30-year title chain from kaveri2.karnataka.gov.in), regulatory checks (RERA, BBMP building plan, OC, fire NOC, BBMP/GBA Khata), financial review (existing tenancy agreements, rent arrears, property tax dues at bbmptax.karnataka.gov.in), physical inspection (structural report, utilities, compliance with sanctioned plan), and GST compliance (18% GST on under-construction commercial property). Missing any element can result in post-purchase disputes, demolished structures, regulatory penalties, or bank loan rejection.

Complexity of Due Diligence Process for Commercial Versus Residential Property Purchase

The purchase of a commercial property in Bengaluru, regardless of whether it is an office space of 2,000 sq ft at Whitefield or a warehouse of 20,000 sq ft around Hoskote, is inherently more complicated than a residential flat purchase process.

A 2025 CREDAI Karnataka report found that over 45% of commercial property disputes in Bengaluru trace back to inadequate due diligence at the time of purchase.

PART A: LEGAL AND TITLE DUE DILIGENCE

1. Title Chain Verification (30 Years Minimum)

2. Encumbrance Certificate (EC): Minimum 30 Years

Get EC from kaveri2.karnataka.gov.in for the full search period. Check for:

• Active mortgages: must have registered discharge deed before purchase

• Court attachments: verify with District Court that orders are vacated

• Lease entries: verify all tenancies and their terms

• Litigation entries: any lis pendens (suit pending) is a red flag

3. Land Use and Zoning Verification

For commercial properties in Bengaluru:

• Verify zoning classification on BBMP/GBA BPAS portal

• Confirm the property is in a commercial zone (C1, C2, or C3) or mixed-use zone

• Check the Revised Master Plan 2015 (under GBA review) for your property's classification

• Properties in residential zones cannot legally be used for most commercial purposes

4. RERA Verification

• All commercial projects above the threshold size must be RERA-registered: rera.karnataka.gov.in

• Verify project completion status, builder's track record, and any consumer complaints

• For under-construction commercial units verify the project registration is active

PART B: REGULATORY AND BUILDING COMPLIANCE

5. Building Plan Sanction

6. Occupancy Certificate (OC)

The most commonly missing document in Bengaluru commercial properties. Without OC:

• Occupation is technically illegal

• Utility connections (BESCOM/BWSSB) cannot be permanent

• Banks refuse loans

• Property cannot be re-leased to new tenants easily

Verify OC at the BDA portal (bdakarnataka.in) for BDA-jurisdiction properties or through GBA/BBMP records.

7. Fire Safety and Other NOCs

For commercial buildings above 15m height or large floor plates:

PART C: MUNICIPAL AND KHATA CHECKS

8. BBMP/GBA e-Khata Verification

9. Property Tax Status

• Verify all property tax paid up-to-date at bbmptax.karnataka.gov.in

• Check for any arrears new buyer inherits unpaid dues

• From FY 2025–26: verify SWM user fee compliance

• Confirm PID number and tax record matches the property description

PART D:  FINANCIAL DUE DILIGENCE

10. Existing Tenancies

11. GST Compliance

For under-construction commercial property:

• 18% GST applies on under-construction commercial property (not on completed properties with OC)

• Verify seller's GST registration

• Confirm ITC (Input Tax Credit) position  if the seller is a builder, proper ITC pass-through affects your tax position

• For completed commercial property with OC: no GST on the transaction itself

12. Income Tax / TDS Compliance

• If purchase price exceeds ₹50 lakh: 1% TDS under Section 194-IA (Form 26QB)

• If seller is NRI: Section 195 applies  higher TDS rates

• Verify seller has no pending income tax dues that could attach to the property

PART E: PHYSICAL AND ENVIRONMENTAL DUE DILIGENCE

13. Structural Inspection

14. Environmental Compliance

For industrial properties near Bengaluru:

• KSPCB (Karnataka State Pollution Control Board) clearance: kspcb.kar.nic.in

• No hazardous waste stored on premises

• No petroleum underground storage tanks (fuel stations)

• Soil contamination assessment if the premises had prior industrial use

15. Survey and Boundary Verification

• Verify survey number and boundaries match the RTC at bhoomi.karnataka.gov.in

• FMB (Field Measurement Book) sketch from the Survey Department

• Physical measurement by licensed surveyor confirm no encroachments

Conclusion

The commercial real estate due diligence process in Bengaluru is multi-portal and multi-disciplinary, and there's always a reason for each portal. The Kaveri 2.0 portal ensures that there are no hidden encumbrances. The BBMP e-Aasthi guarantees that the Khata is clear. Building plan sanction & OC ensures that the construction is legal. The RERA registration process verifies the accountability of the developer. Tenancy agreements show the date by which you can take possession or sublet the premises. Missing out on any one of these portals will ensure that you face the issue only after you have made the payment. Take this list into consideration before making the advance payment, hire a lawyer for the legal due diligence, and an engineer for the physical due diligence.
