Confirmed Threat

A two-alarm fire likely sparked by fireworks tore through the Alpha Sigma Phi fraternity house at 4554 19th Avenue NE in the University District during the early hours of July 5, 2025, hours after July 4 celebrations. More than 80 Seattle firefighters responded beginning around 3:49 a.m., and a UW Alert update at 5:07 a.m. confirmed that all individuals inside had been accounted for. No injuries were reported, but the fire displaced dozens of residents and caused an estimated $1.5 million in damage.

UW Alert: Seattle Fire is responding to a fire at a fraternity house in the 4500 block of 19th Ave NE. Avoid the area while crews work.

This text has been reconstructed from news coverage and may not reflect the exact original wording.

Seattle Fire was dispatched just before 4:30 a.m. (reported alternately as ~3:49 a.m.) to the Alpha Sigma Phi house at 4554 19th Avenue NE; the wording of the first UW Alert is reconstructed from the reported avoid-the-area messaging and is marked unconfirmed.
This is a fire emergency notification rather than a crime warning, so the operative instruction was to keep the public clear while roughly 80 firefighters worked the two-alarm blaze.
The fire occurred in the University District Greek row, an area dense with fraternity and sorority houses, raising the stakes for a fast accounting of residents.

UW Alert: Firefighters have concluded their search of the fraternity house. All individuals inside have been accounted for.

This text has been reconstructed from news coverage and may not reflect the exact original wording.

Hoodline reports that at 5:07 a.m. PDT UW Alert issued an update stating firefighters had concluded their search and all individuals inside had been accounted for; the wording is reconstructed from that paraphrase and is marked unconfirmed.
This 'all accounted for' message functions as the all-clear for a fire — confirming no one was trapped — rather than lifting a shelter-in-place order.
The roughly 78-minute gap between the dispatch and the all-accounted-for update reflects the time needed for primary and secondary searches of a four-story house.
Context

Background

The fire struck the Alpha Sigma Phi house at 4554 19th Avenue NE in the University District in the early morning hours of July 5, 2025, against the backdrop of a chaotic night of Fourth of July fireworks across Seattle. More than 80 firefighters responded to the two-alarm blaze, which heavily damaged the roof, attic, and top floor. Hoodline reported that a UW Alert update at 5:07 a.m. confirmed all individuals inside had been accounted for, and the Spokesman-Review later reported investigators believed fireworks likely caused the fire, though the official cause was undetermined. KING 5 reported the fraternity offered a $10,000 reward for information and that the fire displaced dozens of students with an estimated $1.5 million in damage. The case shows UW Alert's role in fire emergencies in the densely packed Greek row, where confirming that every resident escaped is the central public-safety message.
