Authorities Made Easy: Building Sanction and Land Rules in Kolkata (2026 Guide)

In Kolkata, who sanctions your building depends on which body governs the plot: Kolkata Municipal Corporation (KMC), Howrah Municipal Corporation, the New Town Kolkata Development Authority (NKDA), or one of the municipalities around them. Plans are filed online by a licensed professional. Before that, two land checks catch people out: converting land still recorded as agricultural, and a land ceiling clearance for plots of 500 sq m or more.

First question: which authority governs your plot?

• Kolkata Municipal Corporation: the city proper, under the KMC Act, 1980 and the KMC Building Rules, 2009. A notification of 11 September 2026, following the KMC (Amendment) Act, 2026, raised the number of wards from 144 to 209, so check your ward against the new list.
• Howrah Municipal Corporation: a separate body, but the KMC Building Rules have applied to it since 2011. A state notification of 26 August 2022 relaxed some of them for Howrah's small plots and narrow lanes, for example allowing 10 m of height where the access is 1.2 to 2.4 m wide.
• New Town: not KMC and not Salt Lake. NKDA sanctions plans under its own Act of 2007 and building rules of 2009, and its building department FAQ says plans can only be filed online, through its OBPAS system.
• Salt Lake (Bidhannagar) and other municipalities: the West Bengal Municipal (Building) Rules, 2007, as amended, filed through the state's single-window portal, e-Grihanaksha (see the Urban Development and Municipal Affairs procedure page). Salt Lake Township has extra provisions of its own.
• Panchayat areas: where the state has declared a development plan, a Panchayats and Rural Development procedure (November 2020) makes the Executive Officer of the Panchayat Samiti the permitting authority, with online applications.

The Kolkata Metropolitan Development Authority (KMDA) does not sanction houses. It is the planning authority for the metropolitan planning area and prepares the Land Use and Development Control Plans (LUDCPs) that say how land may be used. If a seller cannot tell you which body governs the plot, treat it as a warning sign; our plot due diligence checklist covers the other checks.

Step one: get the land papers in order

KMC's FAQ on its Common Application Form lists the prerequisites: the BL&LRO mutation and conversion certificates, the land ceiling NOC, a property tax NOC, and clearances where trees, water bodies or heritage are involved. The state's municipal checklist adds the registered deed and, where it applies, development permission under the West Bengal Town and Country (Planning and Development) Act, 1979; in Salt Lake Township, the Final Possession Certificate too. So the order is: deed, mutation in your name, then everything else. The land department's portal is Banglarbhumi.

Step two: land conversion, if the record says agricultural

Change of land use is regulated by sections 4A to 4D of the West Bengal Land Reforms Act, 1955. The state's guidance on conversion says you apply after mutation, with the deed, an up-to-date rent receipt, the mutation certificate and a map of the plot and its neighbours. Its FAQ sends applications to the Block Land and Land Reforms Officer for up to 10 decimals, the Sub-divisional officer for up to 1 acre and the District officer above that. A field enquiry and a hearing follow; neighbours' NOCs have not been needed since 2015.

• KMDA checks the land use. Under a KMDA procedure of 16 September 2025, land reforms officers refer plots inside the Kolkata Metropolitan Planning Area to KMDA to confirm the use fits the gazette-notified LUDCP. Check the LUDCP for your area before you apply.
• Wetlands need special sanction. Banglarbhumi notes that converting land under the East Kolkata Wetlands Act, 2006 needs the competent authority's sanction under section 9 of that Act.

The guidance cites orders up to 2015 and its fee table covers conversion to industrial and commercial use, so ask the land reforms office for the current fee. We found no 2025 or 2026 reform of the conversion process.

Step three: the land ceiling NOC for plots of 500 sq m or more

Rule 4(4) of the KMC Building Rules says that where the plot is 500 sq m or more and the Urban Land (Ceiling and Regulation) Act, 1976 applies, the application must carry a no objection certificate from the Competent Authority under that Act. UDMA says the 2007 municipal rules require the same. At 720 sq ft to the katha, 500 sq m is roughly 7.5 katha.

• It turns on plot size, not house size, and covers additions and alterations too.
• Apply online on the ULC clearance portal; offline applications stopped after 30 June 2022. The Competent Authority checks that you hold no excess vacant land.
• KMC's fallback: if the certificate is not issued within three months of the reference, the requirement is deemed waived.

Will it go away? Finance Minister Swapan Dasgupta said on 26 June 2026 that the state will scrap the Act (Swarajya) and repeated on 2 October 2026 that it "has to go" (NewKerala). Neither report mentions a bill, and we found no repeal notified as of 16 October 2026. Until there is one, budget for the NOC.

Step four: the building permit

Inside KMC

Only a KMC-empanelled Licensed Building Surveyor (LBS) or architect can apply, on the owner's behalf, through the online Common Application Form, which also routes outside NOCs such as fire, pollution control, the airport authority and KMDA. The FAQ gives 15 days for those NOCs and 30 days for sanction from the date of application. Who must sign depends on the building (rule 47):

• a house up to 10 m high without deep foundations: at least an LBS;
• 10 m to 15.5 m, or any piling, basement or deep foundation: an LBS and/or an architect, plus a structural engineer;
• anything larger: an architect, a structural engineer, a geotechnical engineer and a structural reviewer.

Fees. KMC's schedule for 2026-27 sets a one-time application fee for a home on a plot of up to 500 sq m of ₹2,000 up to 7 m high, ₹5,000 up to 10 m and ₹11,000 up to 12.5 m. The permit fee then depends on covered area and road width, with multipliers by use and extra charges for wet work, stacking and drainage. A permit is valid for at least five years and can be renewed up to ten years in all (rule 15).

In Salt Lake and the other municipalities

e-Grihanaksha grades each file as low, medium or high risk. Under the state's risk classification (gazetted February 2023), a house for your own use of up to 400 sq m built-up and 10 m high, on shallow foundations with nothing underground, is generally low risk and needs an LBS. Drawings go through an auto-scrutiny engine, and for low-risk files UDMA's procedure runs from scrutiny and payment straight to a digitally signed permit. The state fee schedule starts at ₹500 for the first 30 sq m of a home for own use plus ₹75 per further 10 sq m; Salt Lake Township charges ₹3.50 per sq ft for residential plots.

In New Town

NKDA asks for a registered architect and an enlisted engineer, and documents including the registered deed, the memorandum of possession, the mutation certificate and paid-up property tax.

Amendments to watch

UDMA's circulars page lists an amendment of the KMC Building Rules dated 4 September 2025, but the file returned "not found" on 16 October 2026, so we have not summarised it. It also lists a June 2026 order adopting the National Building Construction Standards 2026 in place of the 2016 National Building Code under the municipal rules. Ask your architect how either affects your plot, and see our explainer on setbacks, FAR and height limits.

Fire clearance: three different thresholds

A basement changes the answer for a house in KMC and the municipalities.

Step five: plinth check and completion

Plinth. KMC's FAQ says the plinth-level intimation is mandatory. Under rule 24, an officer inspects within seven days of your notice. e-Grihanaksha handles plinth and occupancy stages online for municipalities.

Completion. In KMC, the completion notice is due within a month of finishing, countersigned by your LBS or architect and structural engineer, with completion plans and a structural stability certificate (rule 27). KMC inspects within 15 days and issues the certificate within ten days of inspection if the work matches (rule 28). Without it there are no municipal water or drain connections, and no one may occupy the building (rule 32). NKDA issues an occupancy certificate through OBPAS. For how long all this adds to a build, see our stage-by-stage construction timeline.

The sequence, in one place

1. Find the authority: KMC, Howrah, NKDA, a municipality or a panchayat.
2. Register the deed and get the mutation in your name.
3. Convert agricultural land through the land reforms office.
4. If the plot is 500 sq m or more, get the ULC NOC.
5. Appoint an empanelled LBS or architect.
6. File online, collect any NOCs and pay the fees.
7. Give the plinth notice before building higher.
8. Get the completion or occupancy certificate before moving in.

Frequently asked questions

Is New Town under KMC or Bidhannagar?

Neither, for building sanction. NKDA sanctions New Town plans through its OBPAS portal. Salt Lake is part of Bidhannagar and files through e-Grihanaksha.

Do I need a ULC NOC to build a house in Kolkata?

Only if the plot is 500 sq m or more. The state has said it will scrap the 1976 Act, but no repeal had been notified as of 16 October 2026.

How long does building plan sanction take in KMC?

KMC's FAQ gives 15 days for outside NOCs and 30 days for sanction from the date of application. It also says details cannot be corrected after final submission and a plan not in order is rejected, so a clean first file matters most.

Can I build on agricultural land near Kolkata?

Only after conversion under the West Bengal Land Reforms Act, and only if the land use plan allows it. East Kolkata Wetlands land needs separate sanction.

Can I file the building plan myself?

No. In KMC only an empanelled LBS or architect can file; NKDA requires a registered architect and an enlisted engineer.

Approvals go faster with someone who has filed with your authority before. Browse architects on MOA, see their published work and message them directly, with no commission on either side.
