Who Can Apply and Do the Work
SDCI allows housing demolition only if one of these applies: the house is owner occupied; it has not been rental housing in the last 6 months; a permit for a new use or new building has already been issued; the project meets the residential deconstruction rules; the structure will be relocated; the city has declared it unfit; or it is in a master planned community zone. You cannot demolish housing to create parking that is not required.
What You Need Before the Permit Is Issued
- A rat abatement declaration confirming a licensed pest control company will treat the site for at least 15 days immediately before work.
- A salvage assessment.
- An asbestos survey meeting Puget Sound Clean Air Agency requirements.
- Tenant relocation steps, if anyone lives in the building.
What Else to Know in Seattle
Because an issued permit for the new building is one of the qualifying conditions, many Seattle demolitions are filed alongside, and wait on, a new house or townhouse permit. That is the main reason Seattle's processing times run long in the city's data.
Seattle Demolition Permit Fees
