How much does demolition cost?

STA 0+120Why there is no published demolition price

Building demolition — houses, commercial structures, anything with a hazardous-materials profile and a foundation to break up — is not a standard highway tender item, so no provincial transportation ministry publishes an average price for it the way it does for excavation or paving. Municipal demolition permit processes vary by city, and none of the cities checked for this guide publish an average demolition cost, only permit application requirements. That leaves genuine site and pavement removal items, which Alberta does tender and price, as the closest official Canadian benchmark, covered next.

STA 0+240Official removal prices: pavement, curb and buried structures

Alberta's 2026 highway tenders price the removal side of civil work directly, which is a useful proxy for the site-clearing component of any demolition scope:

Removing and disposing of concrete surfacing averaged $37.26 per m²¹ per square metre, curb and gutter removal averaged $32.60 per m¹ per metre, and asphalt surfacing removal averaged $67.63 per m³¹ per cubic metre. Buried structures are priced separately: removing and disposing of an existing culvert up to 700 mm diameter averaged $119.48 per metre, rising to $149.60 for larger diameters — see the culvert installation cost guide for the full removal table. None of these are building demolition prices; they are official Alberta rates for removing the pavement, curb and buried infrastructure that a demolition or redevelopment site typically also has to clear.

STA 0+360Demolition method: mechanical, selective and deconstruction

Three broad approaches cover most demolition scopes, and the method chosen changes both the cost and the timeline:

• Mechanical demolition. Excavators with shears, hammers or grapples take a structure down quickly. The lowest-cost method per square foot in most cases, and the standard approach for a straightforward teardown with no salvage requirement.
• Selective demolition. Removing specific interior elements or a portion of a structure while leaving the rest standing — common in a renovation or partial-building project, and slower and more labour-intensive per square foot than a full mechanical takedown.
• Deconstruction. Manually dismantling a structure to maximize material salvage and recycling. Slower and more labour-intensive than mechanical demolition, but can reduce disposal tipping fees and, on some projects, is required or incentivized by a municipal green-demolition program.

Dust and noise control, temporary fencing and erosion control around the site are usually priced into the contractor's mobilization rather than broken out separately, but confirm what is included before comparing two quotes that may not be scoping the same site-protection work.

STA 0+480What actually drives a building demolition quote

Without a published rate, a demolition quote is built from a specific set of drivers:

• Hazardous materials survey. Most municipalities require a designated-substances or hazardous-materials survey (asbestos, lead paint, and similar) before a demolition permit is issued for an older structure. No official survey fee is published; it is billed by private environmental consultants and its findings can add significant abatement cost before demolition itself starts.
• Structure size, type and construction. A wood-frame house, a masonry building and a structure with a full basement all demolish at different rates and with different equipment.
• Disposal and tipping fees. Demolition debris is trucked to a landfill or recycling facility and charged a tipping fee per tonne, set by each facility, not by any province-wide rate.
• Salvage and recycling value. Concrete, asphalt, metal and sometimes lumber can be recycled or sold for salvage, which can offset part of the disposal cost — the net effect depends on local scrap and recycling markets.
• Utility disconnects. Gas, power, water and sewer usually have to be formally disconnected by the utility before demolition, which can add lead time even where it adds little direct cost.
• Site restoration after. Backfilling a basement excavation and grading the lot afterward is its own line item — see the excavation and site preparation cost guides.

STA 0+600House versus commercial demolition

A single residential teardown and a commercial building demolition scale differently, beyond the obvious size difference:

• Commercial structures more often involve structural steel, larger foundations, and a higher chance of encountering designated substances that require licensed abatement before mechanical demolition can start.
• Residential teardowns in established neighbourhoods often face tighter access, closer neighbouring properties, and municipal rules about noise, dust and working hours that a rural or industrial site does not.
• Both need the permit and hazmat survey lead time factored into the schedule before physical demolition can start — this is frequently the longest part of the timeline, not the demolition itself.

Neither category has a published price, but the cost drivers scale in a predictable direction: more structure, more materials complexity and tighter access all push the number up, while a straightforward wood-frame structure on an open, accessible site with a clean hazmat survey is the fastest and lowest-cost scenario a contractor will see.

STA 0+720What to send for a price

For a comparable demolition quote: the structure's size, age and construction type, whether a hazardous-materials survey has already been done, site access for demolition equipment and disposal trucks, whether the foundation and basement (if any) should be removed or left, and what should happen to the site afterward (backfilled and graded, or left open for the next phase of construction).

Ask each contractor to confirm the same scope in writing before comparing prices: whether the hazmat survey and abatement are included or excluded, whether the foundation comes out, who pays the disposal tipping fees, and who keeps any salvage value. Two quotes that look far apart in price are frequently pricing different scopes rather than the same job at different rates.
