By How much does it cost to demolish an old house in Kolkata in 2026? Whether you are purchasing an ageing property, clearing ancestral land or preparing a plot for new construction, the total expense goes well beyond demolition labour and JCB charges. Rubble loading, Kolkata Municipal Corporation (KMC) debris transportation fees, structural engineering, safety arrangements and final site clearance can add substantially to the budget.
This Kolkata house demolition cost calculator uses KMC’s published 2026–27 construction and demolition (C&D) waste charges alongside adjustable estimates for plot size, building height, road access, shared walls and debris-hauling distance. For example, demolishing a ground-plus-two (G+2) building covering a 3–4 cottah plot carries an indicative working budget of ₹10 lakh, with a conservative provision of ₹12–13 lakh until contractor quotations are confirmed.
Use the interactive calculator to estimate demolition costs per property, compare itemised expenses, calculate potential salvage recovery from steel, bricks and timber, and review KMC demolition requirements, documentation and pre-purchase checks before committing to the project.
Demolition & Site Clearance Cost Assessment in Kolkata
An interactive planning companion for tearing down an existing structure and clearing a plot — built around KMC’s published 2026–27 fee schedule and a worked reference case: a ground-plus-two (G+2) house on a 3–4 cottah plot. Search any Kolkata locality below to see jurisdiction, access and haul-distance context alongside a live cost calculator that now adjusts for road access, shared walls and more.
Filter by area
Search any of the 577 indexed Kolkata localities to see its postal zone, likely KMC jurisdiction, and general access & haul-distance context. This reclassification is indicative — a planning aid, not a boundary survey — and sits alongside (never replaces) the one documented reference case below.
Live KMC debris & transport calculator
Built directly from KMC’s published formula for sites up to 500 m² collected and transported by KMC: built-up area → demolition waste tonnage → transport + 10% supervision fee. Adjust plot size, floors and the site conditions below — every adjustment below recalculates the budget in Step 3 live.
1 cottah = 720 sq ft. Formula: built-up area (sq ft) ÷ 10.7639 × 0.45 tonne/m² × chosen rate × 1.10 supervision. Supervision stays at 10% for any plot up to 500 m² (this calculator’s full 2–6 cottah range). Confirm your actual tonnage and any loading charges with KMC.

Itemised working budget
The reference case’s planning budget for a 3–4 cottah, G+2 house. Lines marked • respond live to the calculator above (transport) or the site-condition toggles (labour, segregation, engineer, contingency carry a small indicative uplift when JCB access is “No” or shared walls are “Yes”). Set your own Administrative & Site Contingency below.
⚠️ Disclaimer: every figure on this page — including the site-condition uplifts above and any salvage recovery shown — is an indicative planning estimate derived from the discussed reference case and KMC’s published schedule. None of it is a contractor quote, a structural survey, or a guarantee of final price. Always obtain dated, itemised written quotations before committing funds.
Plot-size scenarios
How waste volume and KMC transport cost scale across the plausible 3, 3.5 and 4 cottah readings of the same plot, all at three floors (G+2), using the reference 20–25 km / ₹570-per-tonne tariff. Your haul-distance choice in Step 2 may shift the transport figure up or down from what’s shown here.
| Scenario | Built-up (3 floors) | Waste | Transport + supervision |

How the estimate evolved
Retained for transparency, not as competing quotes — each stage reflects a new confirmed fact. The final two rows supersede everything above them.
Compliance, safety & permissions
KMC-published requirements and good-practice safeguards before any demolition contract is signed.
⚠️ Disclaimer: this section summarises publicly available KMC guidance as of the preparation date; rules, forms and officers change. It is not legal advice — verify the current process with KMC before acting.
Salvage value & contractor commercial terms
Potential recoveries include reinforcement steel, iron, old timber, doors, windows, whole bricks and fittings — but no reliable salvage credit can be calculated before an on-site inventory.

Scope every quotation should cover
⚠️ Disclaimer: the salvage calculator above is an editable planning placeholder, not a valuation — it only reduces the Step 3 total when you set “Owner retains” in Step 2, and even then only as an illustrative net-cost view. Treat any recovered value as a bonus to negotiate, not a line you can bank on until materials are actually inventoried and sold.
Pre-purchase verification checklist
Track what’s confirmed. Your progress is saved locally in this file only.
For a 3–4 cottah, ground-plus-two old house occupying almost the entire plot, with JCB access and no common walls:
Carry the higher figure until a structural engineer, KMC and contractors confirm scope and final prices. The purchase price, registration/stamp duty, any major hazardous-material remediation, new design/sanction fees and new construction are outside this demolition allowance.
