Buying a home is a milestone, but in Bengaluru’s competitive real estate market, a “sanctioned plan” isn’t always a guarantee of legality. Many buyers realize too late that their building has bypassed critical norms, leading to legal battles or the denial of an Occupancy Certificate (OC).

Here is the essential guide to protecting your investment under the 2026 BBMP/GBA guidelines.

1. The “Road Width” Trap

One of the most frequent violations involves road width. Builders occasionally obtain plan sanctions by misrepresenting the width of the access road.

• The Risk: Even if you have an approval document, if the physical road is narrower than what is required by law for that building height, the project is technically illegal.
• The Consequence: This can lead to future litigation or issues with government officials, even if you were unaware of the error at the time of purchase.

2. Small vs. Large Scale Projects

While premium builders typically adhere to 100% of the norms to protect their brand, smaller projects (specifically those with fewer than 30–50 units) require extra scrutiny.

• In some cases, “small mistakes” or deviations are covered up to secure a quick approval.
• As a buyer, you must verify the genuineness of the documents rather than taking the builder’s word at face value.

3. Why an Advocate’s Review Isn’t Enough

Most buyers hire an advocate to check the title deeds (ownership history). While this is necessary, an advocate usually cannot tell if the building violates technical bylaws.

• The Solution: Before signing the agreement, take the sanctioned plan to a qualified engineer.
• An engineer can verify if the setbacks, floor-area ratio (FAR), and fire safety norms are actually being followed on-site.

Buyer’s Safety Checklist for 2026

• Physical Verification: Does the road width in front of the building match the measurement on the sanctioned plan?
• Technical Audit: Has a professional engineer reviewed the building’s deviations and norms?
• OC & CC Track Record: Check if the builder’s previous projects received Occupancy Certificates without delays.
• Transparency: Be wary of builders who suppress minor “errors” in their approvals.

The Bottom Line: Don’t let the excitement of a new home blind you to technical realities. A small technical deviation today could result in your property being classified as unauthorized tomorrow. Verify before you buy.
