Compare demolition cost per square foot by project type, size, material, access, debris, permits, and hazmat risk.
Estimated total = area x base rate per sq ft x material/access factor + permits + debris + contingency
Use this mathematical model to prepare budget expectations, then confirm local labor, tipping fees, permits, and utility disconnections prior to contractor signoff.
| Scenario | Planning Range | Project Notes |
|---|---|---|
| 100 sq ft selective demo | $400-$1,700 | Small interior or deck/floor removal projects often price higher per sq ft because mobilization is fixed. |
| 1,000 sq ft residential demolition | $5,000-$17,000 | House demolition rates depend heavily on material, access, and disposal. |
| 5,000 sq ft commercial demolition | $25,000-$125,000 | Commercial ranges widen with safety plans, equipment, utilities, and debris logistics. |
Residential structural demolition commonly falls into lower per-square-foot bands when access is clear and debris is standard framing. Brick, concrete, basements, and hazardous material testing push the rate higher.
Commercial demolition can look cheap on simple warehouse tear-outs and expensive on multi-story, occupied, or regulated sites. Always separate interior strip-out from structural demolition.
A 100 sq ft job still needs travel, setup, tools, debris handling, and minimum crew time. That is why small projects often show a higher effective rate than full-building work.
Many residential projects fall around $4-$17 per sq ft, while commercial and complex selective demolition can range much wider. Local labor, debris, permits, material, and access decide the final rate.
Use it as a first-pass budget. Then add specific line items for permits, dumpsters, hazmat testing, utility disconnects, slab removal, and contractor contingency.
