Every plot of land in West Bengal is recorded with a classification in its Khatian. Knowing what these classifications mean — and when land needs to be legally converted before you can build on it — can save you from a very expensive mistake.
Common land classifications in West Bengal
- Sali / Shali — agricultural land, typically paddy (rice) fields.
- Danga — higher, drier agricultural land suitable for various crops (not paddy).
- Doba — low-lying land, water bodies or marshy/wetland terrain.
- Bastu — homestead land, i.e. land already classified for residential use.
- Commercial / Industrial — land classified for business or manufacturing use.
Only Bastu (and land specifically classified commercial/industrial) can be legally built on for that purpose. Sali, Danga and Doba are agricultural classifications — building a house or shop on such land without first converting it is illegal, even if you own the land outright.
What is Land Conversion (NA / Nayavad Conversion)?
Land conversion is the official process of changing a plot’s recorded classification from agricultural to non-agricultural (residential/commercial) use. It updates the government record to legally permit construction and is also usually required before a bank will approve a home loan against the land.
This step is not optional. Constructing on unconverted agricultural land can lead to demolition of the structure and penalties from the local authority — even years after construction, and even for a bona fide buyer who didn’t realise the land was unconverted. Always check the Khatian classification before buying, and before building.
How to apply for land conversion

Offline: Submit Form 1A at your Block Land & Land Reforms Office (BL&LRO) along with supporting documents and the treasury challan.
Documents typically required
- Mouza map
- Mutation certificate (the land must already be mutated in your name)
- Latest land revenue (khajna) receipt

Timeline, fees and restrictions
Conversion typically takes around 2 to 6 months, with fees generally up to about Rs. 500 per challan as per the government circular (subject to change — always confirm the current fee). The BL&LRO handles applications, with appeals going to the District Collector. Certain categories of land — wetlands, forest land and other protected zones — cannot be converted under any circumstances, regardless of ownership.
