HOW MUCH DOES IT COST TO DEMOLISH A HOUSE?
HomeGuide puts a typical house tear-down at $6,000 to $25,000, or $4 to $10 per square foot, rising to as much as $25 per square foot when asbestos or lead is present. In Seattle, removing housing needs an SDCI demolition permit, and you must meet asbestos survey requirements, arrange rat abatement for at least 15 days and complete a salvage assessment before demolition.

Seattle's demolition rules
- A permit is required. SDCI: "You need a demolition permit to remove housing."
- When housing can be demolished. One of these must apply: the house is owner-occupied; it hasn't been rental housing in the last 6 months; a permit for a new building or use on the site has been issued; the work follows the City's residential deconstruction rules (Director's Rule 4-2009); the house is being relocated; the City has ordered it unfit to live in; or it's in a master planned community zone.
- Asbestos first. SDCI says you must meet asbestos survey requirements before you can get a demolition permit; contact the Puget Sound Clean Air Agency.
- Rats. The application must include a Rat Abatement Declaration: a licensed pest control company must provide abatement for at least 15 days before work starts.
- Salvage. SDCI requires a salvage assessment for all projects that include demolition.
- Other limits. Housing can't be torn down to create parking that isn't required. Landmarks, environmentally critical areas and tenant relocation rules can apply, and electrical service changes may need Seattle City Light approval.
Demolition vs deconstruction
| Method | Per sq ft | Total |
|---|---|---|
| Mechanical demolition | $4–$10 | $6,000–$25,000 |
| Deconstruction (taking it apart to salvage) | $8–$16 | $10,000–$35,000 |
