Seattle Fire crews found three separate small electrical fires burning inside a vacant, single-story warehouse on the 7200 block of West Marginal Way S early Monday, prompting firefighters to call in a specialized apparatus built specifically to fight electrical blazes without water. All three fires, discovered inside the roughly 150-by-150-foot building, were brought under control, and crews requested that Seattle City Light cut power to the structure.
The department shared the update in a post on X just before 4 a.m., according to the Seattle Fire Dept., which confirmed the fires as electrical in nature and tied to the vacant warehouse. Crews added Energy 1 to the response, a custom rig equipped with 11,000 pounds of carbon dioxide that Seattle Fire launched in 2023 in partnership with Seattle City Light to smother complex electrical fires in high-voltage infrastructure before the equipment can be fully de-energized, according to Powerlines, Seattle City Light's blog.
The joint response reflects a coordination model that appears to be unique among North American cities. Seattle is the only city on the continent running a dedicated joint Energy Response Team pairing its municipal power utility with its fire department to manage emergency grid shutoffs and specialized electrical firefighting, per The Seattle Medium. The team was created to limit widespread power outages during infrastructure fires like this one.
An Industrial Corridor Already Under Traffic Strain
The fire broke out along a stretch of West Marginal Way S that has become a key detour route amid ongoing lane closures on the nearby northbound 1st Avenue South Bridge over the Duwamish Waterway, according to West Seattle Blog's report on the callout. Emergency units from multiple precincts were dispatched to the scene while bridge repairs continued to restrict northbound traffic through the area.
It is not the first time fire crews have responded to this stretch of the corridor. In February 2018, Seattle Fire units responded to a fire inside an excavator at a nearby Waste Management facility on the same block, a reminder that industrial processing and storage sites have long lined this section of West Marginal Way.
Vacant Buildings Remain A Growing Concern Citywide
The warehouse fire adds to a broader pattern city officials have been tracking for several years. Fires in vacant buildings across Seattle surged from 77 incidents in 2021 to 91 in 2022 and 130 in 2023, according to Seattle Fire Department statistics. By March 2025, the department was actively tracking 139 vacant, derelict buildings across the city that met criteria for demolition or major structural remediation, KOMO News reported, with dozens of those sites having already experienced at least one fire.
That surge pushed the Seattle City Council to unanimously pass an emergency ordinance in June 2024 granting the fire department authority to order swift demolition or remediation of hazardous vacant buildings that pose immediate public safety risks. Separately, vacant properties with uncorrected code or entry violations can be enrolled in the city's Vacant Building Monitoring Program, which subjects owners to monthly inspections, fees up to $781.84 and daily civil penalties starting at $150 until the property passes three consecutive monthly checks, per the Seattle Department of Construction and Inspections. It remains an open question whether this particular warehouse was enrolled in that monitoring program, and what caused the initial electrical short at the building's exterior.
A Site Slated For Future Redevelopment
The block sits near a 3.9-acre state-owned parcel designated for Glassyard Commons, a $3.3 million transitional shelter project planned for 2026 that would include 72 RV parking spaces and 20 tiny homes, according to Westside Seattle. The surrounding South Park and Highland Park area has drawn intense community attention over vacant parcels and security in recent months.
Nationwide, roughly 25,000 fires break out in vacant residential and commercial structures each year, with about 37 percent attributed to intentional fire-setting, according to U.S. Fire Administration data cited in Hoodline's earlier North Seattle squat house bust coverage. Vacant structures like the West Marginal Way warehouse carry added risk for firefighters and surrounding utility lines, underscoring why Seattle Fire treats even small electrical fires in empty buildings as a priority response.
