If you are considering buying agricultural land in the Kolkata suburbs like Joka, Newtown or Pailan, and building on it or using it for commercial/residential purposes, you’ll very likely need an NA (Non‑Agricultural) Conversion Certificate. Without it, the law may not permit permanent constructions, bank loans might get refused, or local authorities could penalize or even pull down structures. This guide takes you through everything you need: the what, why, who, what documents, how, cost, and how to avoid hassles.
What is NA Conversion & Why It Matters
Definition: NA conversion refers to legally transforming the status of land from “agricultural usage” to “non‑agricultural usage” (for example residential, commercial, industrial, etc.).
Purpose: It is essential because many laws reserve agricultural land for farming or related uses; using agricultural land for building or businesses without conversion is illegal.
Consequences of skipping it: Without conversion, building permissions won’t be granted, loans secured on the land may be rejected, property resale may be difficult, property taxes or fines may be higher, or illegal use may invite penalties or demolition.
Relevance in Kolkata Suburbs: Suburban expansion means many agricultural lands are being developed. Areas like Joka, Newtown, Pailan are seeing rapid growth; conversion is often required before residential/commercial development.
Legal Framework & Authorities Governing NA Conversion in West Bengal
West Bengal Land Reforms Act (Sections 4A, 4B, 4C, 4D)
The West Bengal Land Reforms Act, 1955 provides the legal basis for land conversion in the state. Conversion is regulated especially under Sections 4A, 4B, 4C, 4D of the Act.
These sections lay down who can apply, what restrictions apply, how fees might be calculated, and what authorities must approve.
Role of Banglarbhumi, Collector / District Magistrate, BLRO / Sub‑Registrar, Municipal / Development Authority
Banglarbhumi is the state land records portal where many land record services, NA conversion applications, mutation, land classification etc., are managed.
Collector / District Magistrate: Generally, the final approving authority or at least a key authority in ensuring that conversion conditions are met.
Block Land & Land Reforms Officer (BLRO): Often local officer / department to whom you submit documents / applications.
Municipal / Development Authority (e.g., KMDA, HIDCO, local municipalities): For plots falling within municipal limits or planned areas, these bodies are involved in approving plans, NOCs etc.
Documents Required for NA Conversion Certificate
To make sure your NA conversion application is accepted without repeated rejections or delays, you must gather all required documents properly. Below are the typical documents requested in West Bengal (especially relevant for suburban areas around Kolkata). Always verify local authority requirements because they can vary by district / block.
Ownership Proof (Sale Deed, Title Deed, Mutation Records)
Registered Sale Deed or Title Deed showing that the applicant is the owner of the land.
Mutation Certificate or mutation entries showing the current owner name in revenue records.
ROR / Khatian / Parcha & Revenue Records
Copy of current Record of Rights (RoR), or Khatian / Parcha in West Bengal. This shows how land is listed in revenue records, area, boundaries, existing status.
NOC(s): Local Authorities, Pollution, Road / Highway, etc.
No Objection Certificates (NOCs) from local bodies / municipalities if land is within their jurisdiction. This might include planning authority, municipal corporation, development authority.
If the proposed usage is commercial or might affect environment, an NOC from the Pollution Control Board might be required.
If land abuts a highway or major road, or railway, there may be NOCs from PWD, Highways, Railways etc.
Survey/Topo Map, Layout Plan, Site Plan & Other Supporting Plans (DPR etc.)
Survey sketch / topo map: Plan showing the boundaries, shape, topography, and adjoining plots / roads.
Site plan / Layout plan: If land is subdivided, or part of a plot development, layout approval may be needed.
Detailed Project Report (DPR) or purpose statement: What you plan to build / use after conversion. Residential / commercial / mixed.
Tax Receipts / No Outstanding Dues / Local Municipal Documents
Recent property tax / land tax receipts to show no dues.
No Outstanding Certificate or tax clearance from municipal / local authority.
Sometimes a “No Dues” certificate is part of the required documents.
Additional Documents (as per Locality or Usage)
Identity Proof of applicant(s) (Aadhaar, PAN, voter ID etc.).
Power of Attorney if the applicant is not the owner but is acting on behalf.
If the land is under mortgage or lien, documents showing consent or release.
In some cases, soil testing or flood risk / environmental certificates may be asked.
Step‑by‑Step Process to Apply for NA Conversion in Kolkata Suburbs
Here is a typical workflow / process, adapted to areas like Joka, Newtown, Pailan etc. Always check local block office / revenue office for exact procedural variations.
Pre‑application Checks & Eligibility
Check that you are the lawful owner (sale deed / title) and mutation is done.
Ensure no outstanding dues (tax, municipal, revenue).
Check that the land is not under any restriction: restricted zone, agricultural only zone without provision for NA conversion, flood‑prone land etc.
Verify local master plan / zoning plan: whether authorities allow conversion at that location.
Online Application via Banglarbhumi / Revenue Portal
Many Land Conversion / NA conversion applications can be submitted online via the Banglarbhumi portal.
Log in, choose “Conversion Application” under Citizen Services (or relevant category).
Fill required fields: district, block, mouza, khatian/plot number, applicant type (self / PoA / agent), purpose of conversion, contact info etc.
Upload scanned copies of required documents: deed, title, mutation, map, site plan, NOCs etc.
Offline Submission (Collector / Land & Land Reforms Officer etc.)
If required or preferred, you may submit the application physically at the office of the Block Land & Land Reforms Officer, or to the Collector’s (District Magistrate’s) office. Some suburbs might require local municipal authority involvement.
Submit all the original / attested documents, fill required forms.
Field Verification / Inspection by Authorities
Once application is submitted, officers may conduct physical inspection of the land: check boundaries, access roads, current usage, whether agricultural activity is ongoing etc.
They will verify that the plot matches the map/survey plan submitted.
Fee Payment & Processing Time
After verifying documents, you’ll have to pay conversion fees as per land type, usage and location. West Bengal’s fee structure varies depending on whether land is in rural area, municipal area or under KMDA etc.
The process can take anywhere from 30 to 90 days (sometimes longer depending on authority, clarity of documents, backlog).
Receiving the NA Conversion Certificate & Follow‑Up Actions
Once approved, you receive the NA conversion certificate / order from the authority.
Keep multiple copies; get the certificate registered or noted in the land / revenue / municipal / development authority records.
Update municipal assessment / tax records, update mutation / revenue records to reflect that conversion.
Only then you can apply for building plan permissions, utility connections etc.
Fees, Costs & Other Charges for NA Conversion
The fee depends on land type, location (rural / municipal / under metropolitan authority), proposed usage (residential / commercial / industrial).
Example: In West Bengal, fees vary per decimal of land; conversion to residential, commercial or industrial have escalating rates.
Apart from conversion fee, you may have costs for maps/survey, architect/site plan, NOC fees, administrative fees.
Also cost for copies, notarization, legal fees if you use a lawyer.
Common Challenges, Pitfalls & How to Avoid Them
Incomplete or incorrect documents: missing mutation, bad maps, outdated or unregistered deeds can delay or reject.
Boundary / area mismatch: what you submit vs what is on ground or what records show should match (maps, survey).
No access road / illegal road access: if approach road is not legal/public, authorities may deny or conditionally approve.
Zoning restrictions / local master plan inconsistency: the land may not be zoned for non‑agricultural use or conversion may be restricted.
Pending dues or outstanding taxes: these must be cleared; authorities require “no outstanding dues” certificates.
Unregistered or irregular title / chain of ownership: mother deed gaps, agents without power, multiple owners not consenting etc.
Environmental or flood‑prone land: If land is in sensitive zone, floodplain, or reserved area, newer permissions may be denied.

- Ready to move status reduces waiting time; some infrastructure already in place.
- Strong potential for appreciation because of upcoming metro, highway road works, location.
- Amenities are planned; community features suggest a self‑contained township rather than isolated plots.
Things you should still verify (using the checklist above):
- Confirm zoning status and whether NA conversion (if needed) has been done.
- Check encumbrance certificate to ensure clear title.
- Ensure all NOCs, permissions, layout plan approvals are legal and in order.
- Physical ground check: slope, drainage, whether land is flood‑prone.
- Exact road access: condition of roads, whether approach to your plot is via public road.
- Surrounding environment: whether neighbouring plots are being developed, quality, types of constructions.
- Utility access and readiness: water, electricity, sewage.
- Confirm any government notifications/plans that may require surrendering land or affect use.
Why This Might Be The Best Time to Buy
- With metro station planned by end of 2028, road improvements, and area being developed, plots may gain significant capital appreciation.
