BDA vs BBMP vs Gramathana: Which Property is Safer to Buy in Bangalore?
This is the single most important question every Bangalore property buyer faces — yet most get a vague or incomplete answer. BDA vs BBMP vs Gramathana isn't just a legal technicality. It determines whether you can get a bank loan, build legally, get a water connection, and sell without headaches 10 years from now. Here's the complete, honest breakdown.
The Three Approval Types — Defined Simply
BDA (Bangalore Development Authority)
BDA is a statutory body that forms residential layouts from scratch on acquired land. When you buy a BDA site, you're buying land that BDA originally acquired, planned, and auctioned. The title chain starts with BDA — and that's the strongest possible starting point in Bangalore.
- BDA forms layouts (like Rajajinagar, Jayanagar, Yelahanka New Town)
- Gives you an allotment letter — this is your golden document
- Properties fall under BBMP limits after formation
- All BDA properties get A-Khata by default
BBMP (Bruhat Bengaluru Mahanagara Palike)
BBMP is Bangalore's municipal corporation. BBMP approval means the building plan was sanctioned by BBMP — it doesn't mean the land was formed by BBMP. A property can be on revenue land, DC-converted land, or BDA land — but if BBMP approved the building plan and issued OC, it becomes a BBMP-approved structure.
- BBMP A-Khata: property is in BBMP limits, property tax is being paid, eligible for water/electricity connections
- BBMP B-Khata: property is in BBMP limits but has an irregularity — unapproved construction, encroachment, or disputed title
- B-Khata is NOT a valid property type for bank loans or legal construction
Gramathana / Revenue Site
Gramathana is ancestral village land that existed before Bangalore's urbanisation. These sites were never "formed" by BDA or any planning authority — they're private agricultural or village land that got absorbed into the city as Bangalore expanded. Gramathana and revenue sites are the most abundant land type in Bangalore's outskirts — and the most risky.
- Not covered under any planning layout
- Cannot get BBMP A-Khata without DC conversion + regularisation
- Building plan approval is difficult or impossible without conversion
- Bank loans are almost never available
Head-to-Head Comparison
| Feature | BDA Approved | BBMP A-Khata | Gramathana / Revenue |
|---|---|---|---|
| Bank Loan Eligibility | ✅ All banks | ✅ Most banks | ❌ Rarely |
| Legal Construction | ✅ Yes | ✅ Yes (with approved plan) | ❌ Not without DC conversion |
| BWSSB Water Connection | ✅ Yes | ✅ Yes | ❌ No |
| Resale Ease | ✅ Easy | ✅ Good | 🟡 Difficult |
| Title Clarity | ✅ Excellent | 🟡 Good (verify) | ❌ Variable — often disputed |
| Price Premium | Highest | Middle | Lowest |
| Risk Level | Very Low | Low-Medium | High-Very High |
DC Conversion — The Bridge Between Revenue and Legal
DC Conversion is the process of converting agricultural or revenue land to non-agricultural residential use. It's issued by the Deputy Commissioner and is a prerequisite for:
- Applying for BBMP Khata
- Getting a building plan approved
- Obtaining a BWSSB water connection
- Making the property bank-loan eligible
The DC conversion order alone is not enough — after conversion, you need E-Khata from the Gram Panchayat or BBMP. Only then does the property become fully legitimate for construction and banking purposes.
The Regularisation Scheme — What It Is and What It Isn't
Karnataka periodically runs regularisation schemes (the last major one was Akrama Sakrama). These allow unapproved constructions and some gramathana properties to get quasi-legal status. Important to understand:
- Regularisation does NOT give you A-Khata
- It does NOT make you eligible for bank loans in most cases
- It does NOT resolve a disputed title
- What it does: allows the structure to exist without demolition threat for the time being
Buyers sometimes confuse "regularised" with "approved." They're not the same. A regularised gramathana site is still a high-risk purchase compared to a BDA or BBMP A-Khata property.

Frequently Asked Questions
What is the difference between BDA and BBMP property in Bangalore?
BDA (Bangalore Development Authority) forms layouts from scratch on acquired land — it's the original planning body. BBMP (Bruhat Bengaluru Mahanagara Palike) is the municipal corporation that administers property tax, building approvals, and Khata within Bangalore city limits. A property can be BDA-formed and BBMP-administered simultaneously.
Can I get a bank loan on a Gramathana property?
Almost never. Banks require A-Khata or E-Khata and DC conversion order as minimum documentation. Pure gramathana or revenue sites without conversion are not eligible for home loans from any major bank.
What is BBMP B-Khata and is it safe to buy?
BBMP B-Khata means the property has an irregularity — unapproved construction, encroachment, or title dispute. B-Khata properties are not bank-loan eligible and carry legal risk. Convert to A-Khata before buying, or avoid entirely.
What is DC Conversion and why is it important?
DC Conversion is the official order from the Deputy Commissioner converting agricultural land to non-agricultural residential use. It's the first step toward making a revenue site eligible for building approval, Khata, bank loans, and BWSSB water connection.
Which is safer — BDA approved or BBMP approved property?
BDA-formed sites have the cleanest title (starts with BDA allotment letter). BBMP A-Khata properties are also safe if the title chain is clean and the building has OC. Both are notably safer than gramathana or revenue sites.
