The Briefing
- More than 100 Seattle Fire Department personnel responded Thursday evening, June 12, 2026, to a three-alarm structure fire at Consolidated Supply Co., a plumbing supply warehouse on Northwest 42nd Street in Seattle’s Ballard neighborhood, near the Ship Canal.
- High winds accelerated fire spread and forced an interior crew evacuation shortly before the building’s roof collapsed; at least one window was also blown out during the incident.
- One firefighter sustained a minor injury; a person inside the building at the time the fire started had already exited before crews arrived, and no civilians were inside when crews conducted a search.
- The large volume of water demand caused pressure drops in the area, prompting deployment of a Seattle Fire Department fire boat to pump water from the Ship Canal to support suppression operations.
- Damage was contained to the Consolidated Supply Co. building; the cause of the fire remains under investigation, with a formal entry into the structure pending safe access.
SEATTLE, Wash. — Seattle firefighters were forced to abandon an interior attack and shift to a defensive posture Thursday evening after high winds rapidly accelerated a three-alarm fire at a commercial warehouse in the Ballard neighborhood, prompting a roof collapse shortly after crews pulled out and requiring a fire boat to supplement water supply. One firefighter sustained a minor injury; no civilians were reported hurt.
The fire was reported at the Consolidated Supply Co. plumbing supply warehouse on Northwest 42nd Street shortly after 5 p.m. A large plume of black smoke rose over the Ship Canal and was visible from across the city, drawing spectators to the perimeter. The Seattle Fire Department upgraded the response to a three-alarm assignment, deploying 15 engine companies and nine ladder trucks for a total response of more than 100 firefighters, according to department spokesperson David Cuerpo.
Crews initially attempted an interior attack, but wind conditions caused the fire to intensify and spread faster than suppression operations could contain. Department spokesperson Kaila Lafferty said at the scene that the wind was a decisive factor. “That wind picked up and really caused it to spread quickly,” she said. Incident commanders ordered firefighters to exit the structure, and the roof collapsed shortly after crews cleared the building. At least one window was also blown out. Firefighters transitioned to a defensive strategy, applying water from a safe exterior perimeter.
The scale of the response placed significant demand on the municipal water supply in the area, causing pressure to drop in some portions of the distribution system. A Seattle Fire Department fire boat was deployed to pump water directly from the Ship Canal to sustain adequate flow for suppression operations. Lafferty said a person who had been in the building before the fire reported the incident to 911 but had exited prior to the arrival of crews. A search of the structure confirmed no civilians remained inside.
The cause of the fire had not been determined as of the time of publication. Investigators were expected to enter the warehouse once structural conditions allowed for safe access. Lafferty said fire crews anticipated remaining on scene into late Thursday night to monitor for flare-ups. Damage was reported as contained to the Consolidated Supply Co. building, with no extension to neighboring structures.
