Why is BDA Approval Important?
BDA approval is not just a piece of paper – it is proof that your property follows the official rules of Bengaluru’s city planning. Without it, the property may face legal challenges or even demolition.
Here’s why BDA approval matters:
- Legal Safety – Confirms the property is officially recognised and free from disputes.
- Strong Resale Value – Easy to sell or rent out in future.
- Bank Loans – Financial institutions give loans only on approved properties.
- Better Infrastructure – Approved layouts follow proper planning with roads, drainage, and parks.
If a property doesn’t have BDA approval, it’s a red flag. But how do you check it? Let’s look at the simple steps.
Steps to Verify BDA Approval
1. Check the Property Documents
Ask the builder or property owner for:
- BDA Layout Approval Letter – Confirms the land is in a legal development area.
- Building Sanction Plan – Ensures construction follows BDA rules.
- Land Conversion Certificate (if applicable) – For agricultural land converted to residential use.
If any of these are missing, you need to be cautious.
2. Visit the BDA Office in Bengaluru
- Head to the nearest BDA office.
- Provide the survey number and property details.
- Officials will confirm if the property has valid BDA approval.
This is the most reliable way to verify approval.
3. Verify Online on the BDA Website
- Visit the official BDA website.
- Use the property’s survey number or layout number to check approval status.
- This option is quick and accessible from anywhere.
4. Consult a Property Lawyer
If you’re unsure about documents or approval, consult a property lawyer. A lawyer can:
- Verify all BDA-related documents.
- Explain the legal impact of buying a non-approved property.
- Save you from future disputes.
5. Double-Check Layout and Sanction Plan
- Ensure the layout itself is BDA-approved, not just the building.
- Verify the building sanction plan, which mentions the number of floors, design, and built-up area allowed.
Without these, you may face problems in future registrations or resale.

What If the Property Doesn’t Have BDA Approval?
If the property is not approved by BDA, think twice before buying. Here’s why:
- Legal Issues – Risk of demolition or government notices.
- Registration Problems – Difficulty in registering property ownership.
- No Bank Loans – Most banks reject loans for non-approved properties.
Sometimes, regularisation is possible through a government scheme, but it’s not guaranteed. To protect your money, it’s best to avoid such properties.
