Most demolition is priced by area, then adjusted for what is in the building, what the access allows and where the waste goes. Those adjustments are larger than the base rate, which is why quotes differ so widely.
Demolition cost: area gives you a starting number only
Published guides put ordinary house demolition in the range of five to ten dollars per square foot, with the wider spread running roughly four to seventeen once unusual sites are included. On that basis a typical two thousand square foot house lands near sixteen thousand, a fifteen hundred foot house near fifteen and a half and a twenty five hundred foot house near twenty one thousand.
Treat those as the shape of the market rather than a quote for your building, because location alone moves the same fifteen hundred square foot house from around six thousand rurally to twenty five thousand in a dense city, where access, hoarding and traffic management do the work.
One factor outweighs everything else. A building with significant asbestos in siding, roofing, flooring or insulation costs two to three times more to take down than the same building without it, which lifts the per square foot figure from the usual five to ten into the region of ten to thirty.
That is a bigger swing than doubling the floor area. It is also why a quote produced without a survey is not really a quote, and why the cheapest number is sometimes cheapest because nobody looked. Construction type matters next: wood framing is cheaper to demolish than brick, concrete or steel.
Published guides put ordinary house demolition at roughly five to ten dollars per square foot, with a wider spread of four to seventeen. Your building needs a survey before that becomes a real number.
Usually one has surveyed for asbestos and the other has not, or one is keeping the salvaged steel while the other credits it back. Ask both questions and the gap often explains itself.
Two to three times the cost of the same building without it, taking the per square foot figure into the ten to thirty range. It is the largest single variable in demolition pricing.
Yes. The same fifteen hundred square foot house can run around six thousand in a rural setting and up to twenty five thousand in a dense city, because of access, hoarding and traffic management.
Crushing concrete on site rather than hauling it out and importing fill, and crediting recovered steel back. Both need to be agreed at quote stage rather than discussed later.
