How Much Does Demolition Cost?

Demolition pricing depends on what you're tearing out and how much of it there is. Interior selective demo runs $2-$8 per square foot when you're removing specific finishes or fixtures while preserving adjacent areas. A full gut to the studs costs $5-$15 per square foot including basic debris handling. Concrete removal (slabs, driveways, patios) costs $4-$12 per square foot for jackhammering, breaking, and haul-off.

Demolition Cost by Project Type (2026)

Demolition Type Cost per Sq Ft 500 Sq Ft 1,000 Sq Ft
Interior Selective Demo$2 - $8$1,000 - $4,000$2,000 - $8,000
Full Interior Gut$5 - $15$2,500 - $7,500$5,000 - $15,000
Concrete Removal$4 - $12$2,000 - $6,000$4,000 - $12,000
Deck / Structure Teardown$5 - $15$2,500 - $7,500$5,000 - $15,000

Prices include labor and basic debris handling. Dumpster rental ($400-$900) and hazmat testing ($200-$600) are additional.

What Affects Demolition Costs

  • Scope of work - Selective demo costs less per square foot than full gut because it requires more careful labor but covers less material. Full gut is faster but generates more debris.
  • Material type - Concrete and masonry cost more to remove than drywall and wood framing because they require heavy equipment like jackhammers and skid steers.
  • Hazardous materials - Homes built before 1978 may contain asbestos or lead paint. Testing costs $200-$600 per sample. If found, abatement can add $5-$20 per square foot to the project.
  • Access and logistics - Upper floors, tight spaces, and difficult dumpster placement all increase labor time and cost. Multi-story demo typically adds 10-20% to the base rate.
  • Disposal method - A roll-off dumpster ($400-$900/week) is standard for most projects. Large projects may need multiple loads. Clean concrete can sometimes be recycled at lower disposal rates.

Frequently Asked Questions

How much does demolition cost per square foot?

Demolition costs range from $2 to $15 per square foot depending on the scope. Interior selective demo (removing specific walls or finishes) runs $2-$8/sq ft. Full interior gut demolition costs $5-$15/sq ft. Concrete slab removal costs $4-$12/sq ft, and deck teardown runs $5-$15/sq ft. These rates include labor and basic debris handling but not dumpster rental.

How much does it cost to gut a 1,000 sq ft house?

A full interior gut of 1,000 sq ft typically costs $5,000 to $15,000 for labor and basic disposal. Add $400-$900 for a dumpster rental and $200-$600 for hazmat testing if the home was built before 1980. Actual costs depend on the number of load-bearing walls, plumbing and electrical to be removed, and the amount of debris generated.

Do I need a permit for demolition work?

Usually yes. Most cities require a demolition permit for structural work, and some require permits even for removing interior walls. Permit costs typically range from $50 to $500 depending on the scope. Homes built before 1978 may also require asbestos and lead paint testing before any demolition begins. Check with your local building department before starting work.

How long does demolition take?

A typical interior selective demo (kitchen or bathroom) takes 1-3 days with a 2-3 person crew. A full gut of a 1,000-2,000 sq ft home takes 3-7 days. Concrete slab removal takes 1-2 days for a standard driveway. Deck teardown takes 1-2 days for most residential decks. Add time for hazmat abatement if asbestos or lead is found.

What is the difference between selective and full gut demolition?

Selective demolition removes specific elements (cabinets, flooring, a wall) while keeping the surrounding structure intact. It costs $2-$8/sq ft and requires more careful work to protect adjacent areas. Full gut demolition strips everything down to studs and subfloor, removing all finishes, fixtures, drywall, and non-structural framing. It costs $5-$15/sq ft but goes faster since nothing needs to be preserved.
