What Does Interior Demolition Cost?

The honest answer to "what does interior demolition cost" is somewhere between $2 and $8 per square foot, and the spread is driven mostly by four things that have nothing to do with the building itself: how easy the access is, how much hazmat is in play, how fast you need it done, and how the debris has to be disposed of. Get those four sorted up front and the price stops being a mystery.

Below is how the numbers typically fall, what pushes them, and how to get a quote that's actually apples-to-apples with others you might be comparing.

Typical ranges by project type

These are ballpark numbers we see in our markets across the Southeast, Midwest, and Sun Belt in 2026. They include labor, equipment, containers, and disposal — what a contractor calls a "turnkey" scope.

Commercial office strip-out: $2.00 – $4.50 per sq ft. A Class A office building with typical drywall, carpet, ceiling tile, cabinetry, and interior glass. Work is usually done after-hours or weekends for active buildings, which adds to the cost.

Retail tenant turnover: $2.50 – $5.00 per sq ft. Adds the cost of removing branded finishes, built-in casework, signage, and refrigeration if present.

Warehouse or industrial interior: $2.00 – $4.00 per sq ft for straight interior work; more if you have racking systems, mezzanines, or production-specific infrastructure to remove.

Restaurant gut-out: $4.00 – $7.00 per sq ft. Commercial hoods, grease ducts, walk-in coolers, and floor drain systems push this higher than a typical retail space.

Residential rehab / house gut: $3.00 – $8.00 per sq ft. Varies widely with finish level, presence of plaster vs drywall, asbestos flooring or siding, and whether the basement and attic are in scope.

A typical 2,000 sq ft office strip-out lands around $6,000–$9,000. A typical 1,500 sq ft fix-and-flip house gut lands around $4,500–$12,000 depending on finish level and hazmat. An industrial plant cleanup can run six figures — but that's not really "interior demolition," it's full facility decommissioning, which has its own pricing model.

What actually drives the price

Access. A ground-floor strip-out with a roll-off at the back door is cheap. A 12th-floor office suite where every load has to go out a freight elevator that locks down at 6pm is expensive. We've seen the same square footage quote at $2.50 and at $5.00 entirely because of access constraints.

Hazmat. Asbestos-containing floor tile, lead paint, PCB ballasts in fluorescent fixtures, or mold colonies all require licensed abatement contractors. That is almost always separate from the demolition scope. A pre-1980 building should be tested before you price the demo — a surprise at mobilization time is a week of schedule slip.

Timeline. A scope priced on a 5-day timeline is not the same scope at 2 days. Compressed timelines mean bigger crews, more equipment, and often premium labor rates. If your schedule has flexibility, say so up front — you'll get a better number.

Disposal. Some waste streams cost more to dispose of than others. Concrete and clean wood go cheap. Mixed construction debris, carpet padding, treated wood, and drywall cost more per ton at the landfill. Recyclable metal actually pays you back — a good contractor separates scrap and credits it against the final invoice.

Contents. "Strip to the studs" is a different scope than "remove everything including cabinets and fixtures." Any fixtures or equipment that have resale value should come out before the demo crew shows up, OR be specifically called out in the scope for disposal. Ambiguity here causes change orders.

Dust control and containment. Interior demo inside an occupied building needs poly barriers, negative-pressure fans, and floor protection. A gut-out on a vacant building does not. That's a real cost difference.

Commercial vs residential — what's different

The big difference isn't the tools or the crew, it's the scheduling and documentation. Commercial work typically needs:

• Certificate of insurance naming the building owner and tenant as additional insureds
• OSHA 10 or 30 hour workers on site
• Daily safety briefings (JSAs) and sign-in logs
• Disposal manifests, especially for C&D waste in regulated markets
• Coordination with building management, freight elevator bookings, after-hours access

Residential work, especially investor rehab gut-outs, usually only needs the contractor to be licensed and insured. House gutting for investors is a different product than commercial demo — faster scheduling, volume pricing, less paperwork — and we price it accordingly.

Timeline expectations

• Single-family house gut: 2 to 4 days start to finish for a typical 1,500 sq ft home including haul-off.
• Retail or office suite under 3,000 sq ft: 3 to 7 days depending on after-hours access requirements.
• Full floor of a commercial building, 10,000+ sq ft: 1 to 3 weeks.
• Industrial interior with equipment and infrastructure: scope-dependent; 2 weeks to 2+ months.

These include mobilization and final sweep. They don't include hazmat abatement if it's needed separately.

How to get a quote that's actually comparable

When you call three contractors, ask each of them the same four questions so you can compare like to like:

1. Is disposal included, and if so to what extent — e.g., does "haul-off" mean a single roll-off or all debris cleared?
2. Is scrap metal recovery credited to the project, and if so how?
3. Is dust containment and daily cleanup included, or is that a change order?
4. What's the liquidated damages or delay clause if the timeline slips?

Answers vary more than you'd think. Our interior demolition scopes include full haul-off, daily containment and cleanup, and scrap recovery credit on the final invoice. Other contractors might quote lower and then bill each of those as a separate line item.

The cheapest quote is almost never the cheapest project. Look at what's included — not just the per-square-foot number — and the comparison becomes honest.
