Approved building plan verification Bangalore refers to checking that the BBMP, BDA or concerned planning authority has sanctioned the construction on a property, and that the building standing on site matches that sanctioned plan in floors, setbacks, coverage and parking. According to the Karnataka Town and Country Planning Act 1961 and BBMP Building Bye-laws 2003, any construction without sanction or in deviation from the sanctioned plan is an unauthorised development, which the civic body can regularise, penalise or demolish even years after purchase.
I have been reading Bangalore property records for more than 20 years. In that time, I have seen more deals fall apart over building plan problems than over title problems. Sellers rarely volunteer this information. You have to ask for it, and you have to know what you are reading.
Here is the uncomfortable truth. A clean sale deed tells you the seller owns the land. It does not tell you the building on that land is legal. These are two completely separate checks, and most buyers only do the first one.
What is an approved building plan and why does it matter before you buy?
A building plan is the drawing submitted to the local planning authority showing what the owner intends to construct. It shows the number of floors, the built-up area on each floor, setbacks from the boundary, parking provision and the height of the structure.
When BBMP or BDA sanctions that drawing, it becomes the approved plan. It is the legal permission to build exactly what is drawn, nothing more.
Why does this matter to you as a buyer? Because the approval belongs to the building, not to the seller. If the seller built four floors when the plan allowed three, the fourth floor is unauthorised. You inherit that problem the day you register the sale deed.
I once had a client who bought a commercial building on a main road in Jayanagar. Beautiful property, clean title, seller seemed honest. Six months later, BBMP issued a notice for the entire third floor, which had been built without any sanction. My client spent the next two years in litigation. The seller had moved abroad.
How do you verify an approved building plan in Bangalore?
The process is more straightforward than most people think, but it needs patience. Here is how I usually run it for my clients.
- Get the sanctioned plan copy from the seller. Ask for the full set: the drawing, the sanction letter and the commencement certificate.
- Check the sanction number and date against BBMP records. You can do this through the BBMP e-Aasthi or Sahaaya portal, or by visiting the local ward office.
- Compare the sanctioned plan with what is actually built on site. Count the floors, measure the setbacks roughly, check the parking area.
- Check the latest property tax receipt and khata. If the tax is being paid on a smaller built-up area than what exists, that is a red flag.
- Look for occupation certificate or completion certificate, if applicable. For older buildings this may not exist, but for anything built after 2007 it usually should.
If you want this done properly without running from pillar to post, this is the kind of work we handle at property document verification in Bangalore. We usually return a building plan opinion along with the title check in two to three days.
What documents do you need for building plan verification?
Keep these ready before you start. Missing documents slow everything down.
- Sanctioned building plan drawing (the stamped copy, not a photocopy of a photocopy)
- BBMP or BDA sanction letter with the plan number
- Commencement certificate
- Latest property tax paid receipt
- Khata certificate and khata extract
- Sale deed or mother deed of the property
- Occupancy certificate or completion certificate, if issued
- Encumbrance certificate (EC) - the record that shows whether the property carries any loan, mortgage or legal due against it
What is the difference between A Khata and B Khata, and does it affect the plan?
This is the question I get asked most often, and the answer is not as simple as people hope.
A Khata means the property is on BBMP records and all dues are paid. B Khata means the property is on a separate register for buildings that were not fully compliant, often because of plan violations or unpaid betterment charges.
| Parameter | A Khata | B Khata |
|---|---|---|
| BBMP status | Fully recorded, dues paid | On a separate register, compliance pending |
| Building plan | Usually matches sanctioned plan | Often has deviations or missing sanction |
| Bank loan | Most banks will lend | Many banks refuse or charge higher interest |
| Resale | Easier, better price | Harder, price usually lower |
| Regularisation | Not needed | Possible under Akrama-Sakrama type schemes, when notified |
Takeaway: B Khata is not automatically illegal, but it almost always signals a building plan problem. Do not buy on the assumption that it will be regularised later.
Sale Deed vs Mother Deed vs Title Deed: what does each prove?
Buyers mix these up constantly. Each one does a different job.
| Document | What it proves | Does it cover the building plan? |
|---|---|---|
| Sale Deed | Ownership transfer from seller to buyer | No |
| Mother Deed | The earlier transaction that brought the property into the seller's chain | No |
| Title Deed | Overall legal ownership of the property, built up through the chain of deeds | No |
| Sanctioned Plan | The permitted construction on that land | Yes |
Takeaway: a perfect title chain means nothing if the building on the land was never sanctioned. You need both.
How long does building plan verification take in Bangalore?
If the seller cooperates and hands over the papers on day one, a proper check takes three to seven working days. That includes the BBMP record pull, the site comparison and a written opinion.
Delays usually come from two places. One, the seller does not have the original sanction letter. Two, the property is old enough that records sit in a physical file at the ward office, not on any portal.
At Legal Brigade, most title and document verifications are turned around in 48 to 72 hours. Urgent checks, where a token advance deadline is ticking, we push through the same day. That speed matters because in Bangalore, the seller is usually holding three other offers.
What happens if you skip approved building plan verification?
Skipping this step is where I have seen the worst outcomes. Let me give you the patterns.
- BBMP issues a demolition notice for unauthorised upper floors, sometimes years after purchase.
- The bank refuses to release the loan because the building does not match the sanctioned plan.
- At resale, the next buyer's lawyer catches the violation and the deal collapses.
- Property tax is reassessed on the actual built-up area, with arrears and penalty.
- In one case, a client could not get an occupancy certificate for a commercial unit, which meant no trade licence, which meant no business.
A property that looked like a bargain turns into a liability. I have watched families lose their entire savings this way.
What are the common red flags to watch for?
If you see any of these, stop and get a lawyer involved before you pay anything further.
- Seller cannot produce the original sanctioned plan
- Built-up area on the tax receipt is much smaller than the actual building
- Extra floors or rooms that do not appear in the drawing
- Setbacks encroached, with the building touching the boundary wall
- Parking shown on the plan has been converted into a shop or room
- Basement used for residential or commercial purposes when it was approved as storage
How much does approved building plan verification cost in Bangalore in 2026?
Costs vary widely. A large law firm may quote anywhere from 25,000 to 60,000 rupees for a full due diligence package, and that is before any site visit charges.
Independent advocates often charge lower, but the depth of the check varies. Some only read the papers. They do not visit the site, do not pull BBMP records and do not compare the drawing against what is standing.
At Legal Brigade, we keep flat, transparent fees for this work. No padding, no surprise line items. For most residential properties, the total is a fraction of what the big firms quote for the same scrutiny.
Compare that to the cost of a demolition notice or a stalled resale. The verification fee is the cheapest insurance you will ever buy.
Self-verification vs lawyer-led due diligence: which should you choose?
You can check a few things yourself. Beyond that, you need someone who reads Bangalore records for a living.
| Parameter | Self-Verification | Lawyer-Led Due Diligence |
|---|---|---|
| Cost | Near zero | Flat fee, transparent |
| Time | Days of running around | 48 to 72 hours |
| BBMP record pull | Hard without contacts | Standard process |
| Site comparison | Rough visual only | Measured against drawing |
| Written opinion | None | Signed legal opinion |
| Risk | High, misses hidden violations | Low, problems caught early |
Takeaway: self-verification is fine for a first filter. It is not a substitute for a proper legal check before you sign anything.
What does Karnataka law say about unauthorised construction?
Under the Karnataka Town and Country Planning Act 1961, the planning authority can issue a notice to demolish or seal any unauthorised development. BBMP has been aggressive on this in the last decade, especially for buildings on main roads and in areas marked for widening.
RERA, the Real Estate (Regulation and Development) Act 2016, adds another layer. Builders must disclose the sanctioned plan and any deviations in the project registration. If a promoter sells you a flat that does not match the approved plan, you have grounds to file a complaint with the Karnataka RERA authority. Complaints can be filed online, and the authority aims to dispose of them within 60 days, though in practice it often takes longer.
Karnataka charges 5 percent stamp duty plus 1 percent registration fee on properties above 45 lakh rupees, as per the Karnataka Stamp Act schedule revised in 2025. That is a significant sum. You do not want to pay it on a building that could be sealed next year.
If you want to read more about how these checks fit into the overall buying process, there are more property buying guides on our site that walk through each step.
What should you do before paying a token advance in Bangalore?
My advice, after 20 years of practice, is simple. Never pay a token advance until you have seen the sanctioned plan, the khata and the latest tax receipt. Even a small advance creates pressure. Sellers know this.
If the seller resists or says the plan is not available, treat that as a serious warning. Genuine sellers have their papers ready. Sellers with a problem stall.
Get the verification done before the advance. Not after. Not in parallel. Before.
I have seen too many buyers call me after they have paid 5 lakh rupees and then discover the fourth floor was never sanctioned. At that point, the seller has the upper hand and you are negotiating from weakness.
If you are at that stage right now, or about to be, you can book a free property consultation and we will tell you exactly what to check first. Most problems in Bangalore property are caught early or not at all. The difference is whether someone with experience is reading the file.
Frequently Asked Questions
How do I verify an approved building plan in Bangalore before buying?
You start with the plan sanction copy and the khata. Ask the seller for the sanctioned plan, the commencement certificate, and the latest tax paid receipt. Then cross-check the plan number at the BBMP or BDA office where the plan was sanctioned. In 20 years, I have seen buyers skip this step and end up with a flat that has an extra floor no one approved. The whole exercise takes about a week if the documents are clean.
How much does approved building plan verification in Bangalore cost?
For a single residential unit, a proper plan verification with a written opinion runs between Rs 8,000 and Rs 15,000 depending on how many documents are involved. If it is an apartment in a large project with a joint development agreement, expect Rs 20,000 to Rs 35,000. Government fees for certified copies are separate and rarely cross Rs 500 per document. Anyone quoting Rs 2,000 for a full check is not doing the work.
How long does a property due-diligence check take in Bangalore?
A straightforward title and plan check takes 48 to 72 hours if the seller hands over clean copies. If we have to pull old EC records from the sub-registrar or trace a mother deed from the 1980s, it stretches to 10 to 15 working days. BBMP plan files sometimes take longer because the file has to be traced physically. I always tell clients to budget two weeks if the property is more than 20 years old.
Can I do approved building plan verification myself or do I need a lawyer?
You can pull the EC online through the Kaveri portal for Rs 30 or so, and you can check the khata on the BBMP site. What you cannot easily read is whether the sanctioned plan matches what was actually built, or whether the deviation falls under the 5 percent tolerance in the Karnataka Town and Country Planning Act. I have caught violations that looked fine on paper but were flagged in the BBMP file. A lawyer reads the file, not just the certificate.
What is the difference between a sanctioned plan and an occupancy certificate?
The sanctioned plan is what the builder was allowed to build. The occupancy certificate, or OC, is proof that what was built matches the sanction. In Bangalore, many buildings run for years without an OC and buyers do not notice until they apply for a loan or try to sell. Under BBMP rules, a building without OC can face demolition or a penalty. Always ask for both, not just the plan.
Where do I check if a building plan is approved in Bangalore?
The sanctioning authority depends on the area and the year. BBMP handles most plans within city limits, BDA handles layouts and larger developments, and BMRDA or the local planning authority covers the peripheral zones. You check the plan number on the sanctioned drawing against the register maintained by that office. I have seen plans from 2009 that were never entered in the register. That is a red flag you cannot ignore.
What happens if I buy a property with an unapproved building plan?
You inherit the violation. BBMP can issue a notice under Section 308 of the Karnataka Municipal Corporations Act and order demolition or regularization with a penalty. Banks usually refuse a loan on such a property, and resale becomes very hard. In one case I handled, the buyer lost Rs 12 lakh in token advance because the third floor was never sanctioned. Get the plan verified before you pay anything beyond the token.
If you are about to sign a sale agreement and the plan sanction is still sitting in a WhatsApp forward, stop and get it checked properly. At Legal Brigade we do a full approved building plan verification Bangalore buyers can rely on, usually in 48 to 72 hours, at a flat fee we tell you upfront before we start. Send us the sanctioned plan, khata, and EC, and we will tell you exactly where the property stands. You can book a free property consultation and we will take it from there.
