How to Check the Building Plan Sanction in West Bengal — Complete Guide 2026
The KMC building plan sanction is the formal approval issued by the Kolkata Municipal Corporation (or local Municipality or Panchayat) before construction begins. The state warning is direct: verify that the sanctioned plan matches the actual building. This guide walks you through filing, checking and using it before any purchase.
What is the Building Plan Sanction in Kolkata?
Definition
The building plan sanction is the legal approval to construct, re-erect, add to or alter any building, issued under the Kolkata Municipal Corporation Act, 1980 and the KMC Building Rules, 2009. It is granted by the Municipal Commissioner or, for low-rise cases, by an empanelled professional under Section 393A of the Act.
The sanctioned building plan Kolkata buyers ask for is the stamped drawing set plus the order. It records every floor, the height, setbacks, parking, staircase, lift well, drainage and the use of each space. Construction without it is illegal. KMC can demolish unauthorised structures and prosecute the owner. Banks refuse home loans on flats raised on land that has no plan, or where the plan does not match the structure.
The state runs two tracks for sanction. The standard track sits with the borough building department and applies to larger and complex buildings. The Section 393A KMC track is the fast lane for residential buildings up to roughly G+3 (about 41 ft height). Here, an Architect or Licensed Building Surveyor empanelled with KMC files the plan electronically; the Municipal Commissioner or Borough Executive Engineer scrutinises and clears it within 30 days. After construction, KMC engineers must inspect before the Completion Certificate is granted, and any deviation triggers action against the professional.

What Does the Sanctioned Plan Contain in Kolkata?
The sanctioned plan is a drawing-plus-order set; read every field and every drawing line before relying on it.
| Field | What it means | What to check |
|---|---|---|
| Premises Number, Ward and Borough | Identifies the exact property the sanction covers | Match these with your deed, KMC NOC, and tax bill |
| Sanction Order Number and Date | Unique KMC reference and effective date | Cross-check on the Plan Proposal Status Search on kmcgov.in |
| Plan Type | Section 393A (LBS / Architect track) or standard track | A 393A plan only covers up to G+3; larger structures require the standard track |
| Floor-Wise Layout | Each floor’s plan, area, and use | Tally exactly with the actual built floor; note every deviation |
| Height and Setbacks | Total height, front, rear, and side setbacks | Compare with the minimums under the West Bengal Building Rules, 2009 |
| Parking and Lift Well | Mandatory parking spaces and lift core | Missing parking is a common compounding issue |
| Empanelled Professional | Architect, LBS, Structural Engineer signatures | Confirm the names match the KMC empanelment list |
