Sanctioned plan verification is the process of checking whether a building's construction matches the approved blueprint from the local municipal authority. According to the Karnataka Municipal Corporations Act 1976, every building must have a sanctioned plan before construction begins, and deviations can lead to demolition or fines. In 20 years of practice, I've seen buyers lose crores because they assumed the builder followed the approved plan.
What is a sanctioned plan and why does it matter before you buy?
A sanctioned plan is the set of drawings approved by the Bruhat Bengaluru Mahanagara Palike (BBMP) or the local planning authority before construction starts. It shows the exact dimensions, floor area, set-backs, number of floors, parking spaces, and common areas. When you buy a flat or villa, you're buying a share of the land and the building built as per that plan. If the builder constructs extra floors, shrinks the garden, or blocks a fire exit, the building becomes illegal. The BBMP can issue a stop-work notice, impose a fine, or even order demolition. I've handled cases where buyers moved in only to get a notice from the BBMP six months later — and they had no recourse because the sanctioned plan didn't match what they bought.
How do you verify a sanctioned plan in Bangalore?
The first step is to get a copy of the sanctioned plan from the builder or seller. They're required to give it to you under RERA (Real Estate Regulatory Authority) Act 2016. Next, you need to cross-check it with the actual building. Here's a step-by-step process I recommend to my clients:
- Ask for the sanctioned plan — demand the final approved plan from the local planning authority, not just a brochure or layout.
- Visit the site — measure the room sizes, corridor widths, and ceiling heights yourself or hire a civil engineer.
- Check the set-backs — the plan will show required open spaces on all sides. A deviation of even a foot can be a red flag.
- Verify the number of floors — count the floors and check if the builder added a stilt or terrace extension not shown on the plan.
- Match the common areas — parking slots, clubhouse, garden, and staircases should match the plan dimensions.
- Get a lawyer to review — we at Legal Brigade compare the plan with the Occupancy Certificate (OC) and sale deed to spot mismatches.
What documents do you need for sanctioned plan verification?
You'll need the following documents to complete a thorough verification:
- The sanctioned plan itself (signed and stamped by BBMP or the planning authority).
- The commencement certificate (shows the plan was approved before construction started).
- The occupancy certificate (issued after completion, confirming the building matches the plan).
- The sale deed and mother deed (to check if previous owners made any alterations).
- Encumbrance certificate (EC) from the sub-registrar for the last 13 years (to see if there are any loans or legal issues).
- Khata certificate and tax paid receipts (to confirm the property is recorded with BBMP).
How long does sanctioned plan verification take?
If you have the plan and OC handy, a basic check can be done in a day. But a full due-diligence — including physical site measurement and EC search — usually takes two to three days. At Legal Brigade, we often do urgent checks in 24 hours because buyers face token-advance deadlines. The BBMP doesn't give out plan copies quickly; you may need to wait a week or two if you apply yourself. That's why many buyers ask us to handle the whole process.
What happens if you skip sanctioned plan verification?
I could write a whole book on this. Let me give you two real cases from my files. A client bought a flat in a six-floor apartment in Rajajinagar. The sanctioned plan showed four floors. The builder had added two floors without approval. The client didn't check. Six months after moving in, BBMP issued a demolition notice for the top two floors. The client lost his flat and the builder had vanished. Another client in Whitefield bought a villa where the builder had converted an open terrace into an extra room. The sanctioned plan showed an open terrace. The buyer paid a premium for that terrace. After registration, the BBMP sent a stop-work notice to seal the room. The buyer had to spend two lakhs to get the room demolished and restore the terrace. Both buyers could have avoided this with a simple plan check.
How much does sanctioned plan verification cost in Bangalore in 2026?
The cost varies depending on who does the work. If you do it yourself, you'll spend maybe two thousand rupees on EC and document fees plus your time. But missing a deviation can cost you lakhs. A professional due-diligence from a law firm like Legal Brigade typically costs a fraction of the property value — we charge a flat fee that's often less than 0.5% of the property value. For a 50-lakh flat, that's around 10,000 to 15,000 rupees for a full title and plan check. Compare that to the risk of losing your entire investment. In 2025, Karnataka charged 5% stamp duty plus 1% registration on properties above 45 lakh (Karnataka Stamp Act schedule, 2025). The verification fee is a small price for safety.
Comparison: Self-Verification vs Lawyer-Led Due Diligence for Sanctioned Plan Check
| Aspect | Self-Verification | Lawyer-Led Due Diligence (e.g., Legal Brigade) |
|---|---|---|
| Time taken | 1-3 weeks (including waiting for BBMP records) | 2-3 days (urgent same-day available) |
| Cost | ₹2,000 - ₹5,000 (EC, document fees, travel) | ₹10,000 - ₹20,000 flat fee (varies by property value) |
| Accuracy | Moderate — you might miss subtle deviations or legal issues | High — trained lawyers cross-check plans, deeds, and site measurements |
| Risk coverage | You bear all risk if something is missed | Professional indemnity; if we miss something, we're accountable |
Takeaway: Self-verification may save you a few thousand rupees, but the risk of missing a critical deviation far outweighs the cost of professional help.
Comparison: A Khata vs B Khata — What It Means for Your Purchase
| Feature | A Khata | B Khata |
|---|---|---|
| Issued by | BBMP (legal properties) | Village accountant or panchayat (often for unapproved layouts) |
| Sanctioned plan needed | Yes — property must have approved plan | Usually no — many B Khata properties lack sanctioned plans |
| Bank loan eligibility | Easy — most banks accept A Khata | Difficult — few banks finance B Khata properties |
| Risk of demolition | Low — if plan matches building | High — BBMP may reject or demolish |
Takeaway: Never buy a B Khata property without a thorough sanctioned plan verification. Many B Khata properties are illegal or deviate from approved plans.

Frequently Asked Questions
How much does property title verification cost in Bangalore?
Title verification fees vary. A basic check including EC, khata, and sale deed review by a lawyer may cost between ₹5,000 to ₹20,000 depending on the property value. At Legal Brigade, we charge a flat fee that is transparent and usually well below 1% of the property value. For a 1-crore property, expect around ₹15,000 to ₹25,000 for a full due-diligence including sanctioned plan check.
How long does a property due-diligence check take?
A standard due-diligence — including EC search, khata verification, and sanctioned plan check — takes two to three working days. If you need it urgently, many firms including Legal Brigade can complete it within 24 hours for an additional fee. Do not skip this step just because the seller is pressuring you.
Can I do property verification myself or do I need a lawyer?
You can do a basic check yourself — like reading the EC and comparing the plan with the building. But I've seen too many buyers miss subtle legal issues like an unreleased mortgage or a plan deviation that's not obvious to the untrained eye. A lawyer brings experience in spotting red flags and can also check title chain and RERA compliance. If your property is worth more than 30 lakh, it's worth spending on a professional check.
What is the difference between sanctioned plan and occupancy certificate?
The sanctioned plan is the blueprint approved before construction. The occupancy certificate (OC) is issued after construction is complete, confirming that the building matches the sanctioned plan and is fit for occupation. You need both for a safe purchase. If the builder has an OC but the sanctioned plan shows a different structure, the OC may be fraudulent. Always verify both.
What are the legal consequences of buying a property with a deviated plan?
If you buy a property that doesn't match the sanctioned plan, the BBMP can issue a notice asking you to demolish the unauthorized portions. You may also face fines, difficulty obtaining loans, and problems selling the property later. In extreme cases, the entire building can be declared illegal and demolished. I've seen families lose everything because they skipped this check.
Is sanctioned plan verification mandatory for resale properties?
Yes, especially in Bangalore where many resale flats have additions like extra rooms, covered balconies, or altered floor plans. When you buy a resale property, you inherit any deviations made by previous owners. Verify the plan before registration to avoid future notices.
Can I get a loan without sanctioned plan verification?
Most banks and housing finance companies require a copy of the sanctioned plan and OC before approving a loan. They will also do their own inspection. If the plan doesn't match, they may reject your loan application or disburse a lower amount. Getting a pre-approved loan does not guarantee final approval if the plan check fails.
If you've got a token advance riding on a deadline, don't gamble on it.
