COVID Updates - Services During Pandemic and Re-Opening

The Fire Marshal's Office is continuing some inspections, plan review and other services consistent with the Governor's re-opening guidance. Our walk in counter at 220 3rd Ave S remains closed. All other services are available with some modifications.


The Seattle Fire Investigation Unit has seven trained and certified fire investigators. The goal for fire investigators is to determine the causes and origins of fires. The investigators collect evidence at the scene and document their findings. The Seattle Police Department uses those findings in their criminal investigation.
