Building plan approval check refers to verifying whether a property's construction has been sanctioned by the local municipal authority and complies with zoning, setback, and floor-area rules. According to the Karnataka Municipal Corporations Act, 1976, any building construction must have prior approval from the Bruhat Bengaluru Mahanagara Palike (BBMP) or the relevant planning authority. In 20 years of practice, I've seen dozens of buyers who skipped this simple step and ended up losing their entire investment.
What is a building plan approval and why does it matter before you buy?
A building plan approval is an official document from the local municipal body, like BBMP, that says the construction plan for a property follows the city's building bylaws and zoning regulations. It includes details like the number of floors, the size of each room, setbacks from the road and neighbors, and the total built-up area. Think of it as the government's green light that the building is legal.
Why does it matter for you as a buyer? In short, if you buy a property without a valid approval, you risk demolition, fines, and trouble getting a home loan or selling it later. A client came to me last year ready to register a flat in Whitefield. The seller showed a nice-looking building, but when I checked with BBMP, the approval was only for ground plus two floors — the building had four floors. The top two floors were illegal. My client backed out and saved crores in potential loss.
How do you verify building plan approval in Bangalore?
Verification is straightforward but you need to know where to look. Start by asking the seller for a copy of the sanctioned plan — it's usually a large-format paper with BBMP stamps and signatures. Then, physically visit the local BBMP office or check the online portal if available. In Bangalore, you can use the BBMP e-Swathu portal to check property details, but not all approvals are digitized.
Here's a step-by-step checklist I give my clients:
- Step 1: Get a copy of the sanctioned building plan from the seller. It should have the BBMP or planning authority's seal, date, and signature.
- Step 2: Cross-check the plan with the actual construction. Count the floors, measure setbacks, and see if the built-up area matches. If the building is bigger than the plan, that's a red flag.
- Step 3: Visit the local BBMP office (ward office) and ask for a certified copy of the approved plan. They charge a small fee — around Rs. 500 to Rs. 1,000 depending on the property size.
- Step 4: Check if the plan is still valid. Approvals are typically valid for 3-5 years, and if construction wasn't completed in time, the approval might have lapsed.
- Step 5: Look for any deviation orders or show-cause notices on the property. You can do this by filing an RTI application or checking with the BBMP town planning department.
Doing this yourself is possible but time-consuming. At Legal Brigade, we usually do this as part of our title verification and turn it around in two to three days. It's a small step that can save you from a big headache.
What documents do you need for a building plan approval check?
To verify building plan approval, you'll need these documents from the seller:
- Sanctioned building plan: The actual plan approved by BBMP or the planning authority. It should show the floor plans, elevations, sections, and site plan.
- Completion certificate (CC): Issued after construction is finished, confirming the building was built as per the approved plan. Without a CC, the building is considered incomplete and may have legal issues.
- Occupancy certificate (OC): This is issued after the completion certificate and confirms the building is fit for occupation. Many banks require an OC to sanction a home loan.
- Khata certificate and extract: Shows the property is recorded in BBMP's books. A Khata without a building plan approval is often a B Khata, which means the building is not fully legal.
- Latest tax paid receipts: These show the property is in the tax net, but be careful — even illegal buildings can pay tax these days.
I always tell my clients: don't rely on the seller's word. Get certified copies from the BBMP office. In one case, a seller showed me a photocopy of the plan that looked fine, but the original at BBMP had different dimensions — the building was encroaching on a stormwater drain. We caught it before the buyer paid the advance.
How long does a building plan approval check take?
If you do it yourself, expect at least a week. You'll need to make multiple trips to the BBMP ward office, wait in queues, and follow up. If you hire a professional like Legal Brigade, we can usually complete the check in two to three days, sometimes the same day if it's urgent. The timeline depends on whether the records are digitized and how cooperative the BBMP staff is.
Here's a rough breakdown:
- DIY check: 5-10 days (including travel and waiting time)
- Professional check (like ours): 2-3 days for a standard check; same-day for urgent cases
- RTI application: 30 days as per law, but often takes longer
If you have a token advance deadline ticking, don't try to do it yourself — you might run out of time. I've seen buyers lose their advance because they couldn't complete the check before the agreement deadline.
What happens if you skip the building plan approval check?
Let me tell you three real stories from my practice:
Case 1: A couple bought a flat in a so-called 'luxury' apartment in Sarjapur Road. They didn't check the building plan because the builder had a good reputation. Two years later, BBMP issued a demolition notice — the building was built on a lake bed and had no approval. The couple lost their entire investment and were stuck in a legal battle for five years.
Case 2: Another buyer registered a house in Banashankari. The building had an approval for ground plus one floor, but the seller had added a second floor without permission. When the buyer tried to get a home loan, the bank refused because the property had a B Khata (which means the extra floor was illegal). The buyer had to pay a huge penalty to regularize the floor, and even then, the property value dropped by 20%.
Case 3: A client wanted to buy a commercial property in Koramangala. The building plan approval was for a residential use, but the seller was using it as a restaurant. The buyer planned to run a office there. If they had bought it, they would have faced a violation notice and possible closure. We caught it during the check and saved them from a bad deal.
In 20 years, I've seen this go wrong dozens of times. The consequences include:
- Demolition order: BBMP can demolish illegal portions at your cost.
- Fines and penalties: Up to 200% of the property value in some cases.
- Loan rejection: Banks won't lend on properties without proper approvals.
- Resale difficulty: Buyers will run away when they see no approval.
- Legal liability: You could be dragged into litigation with the municipality or neighbors.
How much does a building plan approval check cost in Bangalore in 2026?
The cost varies depending on how you do it:
| Method | Estimated Cost (Rs.) | Time | Risk of Missing Issues |
|---|---|---|---|
| DIY (self-check at BBMP) | 500 - 2,000 (certified copy fees + travel) | 5-10 days | High (you may miss subtle violations) |
| RTI application | 10 (application fee) + photocopy costs | 30 days + | Moderate (depends on quality of records) |
| Private architect / engineer | 5,000 - 15,000 | 3-5 days | Low (professional eye) |
| Property lawyer / due diligence firm (like Legal Brigade) | 7,500 - 20,000 (flat fee, includes title check + plan verification) | 2-3 days (same-day if urgent) | Very low (we cross-check with EC, Khata, and site visit) |
Takeaway: Spending a few thousand rupees on a professional check is cheap insurance compared to losing crores on a property that gets demolished. At Legal Brigade, our fees are transparent and usually a fraction of what large firms quote, because we've been doing this for 20 years and know exactly where to look.
What is the difference between A Khata and B Khata with respect to building plan approval?
In Bangalore, Khata is the property's identity card with BBMP. An A Khata means the property has a valid building plan approval and is fully legal. A B Khata means the property has some irregularity — typically no approval, deviation from approved plan, or construction on unauthorized land.
Here's a quick comparison:
| Feature | A Khata | B Khata |
|---|---|---|
| Building plan approval status | Valid and compliant | Missing or violated |
| Bank loan eligibility | Easier (most banks accept) | Difficult (only select lenders) |
| Resale value | Higher | Lower (20-30% discount) |
| Risk of demolition | Low | High |
| Property tax | Standard (lower for residential) | Higher commercial rate even for houses |
Takeaway: Always insist on an A Khata property. If the seller says they can get it converted later, be very skeptical — it's often a long and expensive process with no guarantee.
Can I get a building plan approval after construction?
Yes, but it's not straightforward. In Karnataka, the Regularization of Unauthorized Constructions Act, 2020 (Act 4 of 2020) allows certain illegal constructions to be regularized on payment of a penalty. But there are conditions:
- The building must not be on government land, lake bed, or stormwater drain.
- The violation must not be 'serious' (e.g., exceeding floor area by more than 25% or building more than allowed floors).
- You must apply within the prescribed window (which may be closed now for some cases).
In practice, regularization is not automatic. I've seen applications stuck for years. It's better to buy a property that already has approval. If you're considering an unapproved property, talk to a lawyer first — don't assume regularization will be easy.
What is the role of a completion certificate and occupancy certificate?
Completion certificate (CC) is issued by the architect or engineer certifying that the building is built as per the sanctioned plan. Occupancy certificate (OC) is issued by BBMP after inspecting the building and confirming it's safe for occupation. Without these, banks won't give loans, and you could face legal issues.
In Bangalore, many buildings have a CC but not an OC. That's a red flag. It means the building might not meet fire safety or structural norms. I advise my clients to ask for both documents before signing the sale agreement.
How does RERA affect building plan approval?
Under the Real Estate (Regulation and Development) Act, 2016, all new real estate projects with more than 500 sqm of land or 8 apartments must be registered with RERA. As part of registration, the builder must submit the sanctioned building plan. If the plan changes later, the builder must get approval from the buyers and RERA. This adds a layer of protection for buyers.
However, RERA doesn't cover individual houses or small projects. Also, many builders in Bangalore still operate without RERA registration. So don't rely solely on RERA — do your own check.
Frequently Asked Questions
How much does property title verification cost in Bangalore?
Title verification fees vary. A basic DIY EC search costs about Rs. 200 to Rs. 500 per year of search. Professional title verification by a lawyer or firm like Legal Brigade typically costs Rs. 7,500 to Rs. 20,000 for a full due-diligence report, including building plan approval check, EC, Khata, and mutation. We charge a flat fee upfront, no hidden costs. For a simple apartment, it's usually on the lower side; for complex properties, it may be higher.
How long does a property due-diligence check take?
At Legal Brigade, we usually return a full title check in two to three days. If you need it urgently, we can do it the same day. DIY can take a week or more because you have to visit multiple offices. The speed of professional checks depends on how quickly the seller provides documents and how accessible the government records are. We've been doing this for 20 years, so we know the shortcuts.
Can I do property verification myself or do I need a lawyer?
You can do a basic check yourself — get the EC from Kaveri online, check Khata on BBMP e-Swathu, and ask for the building plan. But a lawyer or professional can spot issues you might miss, like a pending litigation, an unreleased mortgage, or a subtle deviation in the building plan. I've had clients who thought the property was clean but we found a court injunction or an inheritance dispute. The cost of a professional check is worth the peace of mind.
What is an encumbrance certificate and why do I need it?
An encumbrance certificate (EC) is a record from the sub-registrar's office that lists all transactions and encumbrances (like loans, mortgages, or legal dues) on a property for a specific period. It's crucial because it shows whether the property is free from debts or claims. For example, if the seller has an unpaid bank loan, the bank has a charge on the property. Without checking the EC, you could inherit that debt. We always get an EC for at least 30 years before we give a title opinion.
What is a mother deed and why is it important?
The mother deed is the oldest deed in the chain of title for a property — the deed that started the current ownership history. It's usually a sale deed or a gift deed from many years ago. Checking the mother deed helps establish the root of title and ensures the seller has a clean chain of ownership. In one case, I found that the mother deed was a forged document; we stopped the deal immediately. Always get the mother deed checked by a lawyer.
What is the difference between sale deed and title deed?
A sale deed is the document that transfers ownership from seller to buyer. A title deed is a general term for any document that proves ownership, including sale deeds, gift deeds, inheritance documents, etc. So a sale deed is a type of title deed. In practice, people use these terms interchangeably. When I say 'title deed', I mean the document that shows who owns the property now. When I say 'sale deed', I mean the specific document that transferred it to the current owner.
What is the stamp duty in Karnataka for property purchase in 2026?
As per the Karnataka Stamp Act, 1957, the stamp duty for property purchase is 5% of the market value (guidance value or sale consideration, whichever is higher) for properties above Rs. 45 lakh. For properties between Rs. 20 lakh and Rs. 45 lakh, it's 3%. Plus, registration fee is 1% of the value. On top of that, there is a surcharge of 10% on stamp duty for properties in urban areas. So the total cost is roughly 6.5% to 7% of the property value. Always budget for this when planning your purchase.
