Gas Smell in the Air After Millcreek House Fire Sends Neighbors Running Into the Streets
Sunday evening in Millcreek was quiet. Then it was not.
At 8:45 p.m., multiple callers flooded 911 with reports of a fully involved house fire at approximately 1990 E. Gregson Ave. By the time crews arrived, flames were already tearing through the attic. But the detail that changes this story is what happened before the fire.
There were explosions first. And neighbors say they had no warning at all.
The House on Gregson Avenue
Crews arrived to find a home fully engulfed, with flames coming from the attic area. Explosions had been heard before the fire took hold. Several surrounding homes were evacuated, and residents poured onto the streets as flames threatened nearby properties.
Eyewitnesses reported multiple stretchers on scene, though no injuries have been officially confirmed. A smell of gas was also reported in the air. The cause of the fire remains under investigation.
When Explosions Come Before the Flames, That Is Not a Typical House Fire
A standard house fire builds gradually. Smoke first, then heat, then visible flame. You usually get some signal.
When explosions precede the fire, that window disappears. The explosion is the first warning. And by then, the home is already gone.
The gas smell reported by eyewitnesses is the detail investigators will focus on. In residential fires where explosions happen before visible flames, the cause is often gas buildup reaching an ignition point suddenly, with no visible warning to anyone nearby.
ABC4 Utah confirmed the initial report, with crews still on scene and residents displaced at the time of publication.
Utah Has Seen This Pattern Before
This is not a new story for the Salt Lake Valley.
In November 2024, a South Jordan home exploded from a gas leak in a pipe installed in 1976, located 150 feet from the house. A 15-year-old died.
The family inside did not smell gas before the explosion. Neighbors said they had zero communication from the gas company, the city, or state agencies.
The NTSB report that followed stated natural gas alarms could have alerted occupants before concentrations reached explosive levels. But here is the problem: most homes do not have them.
What also gets missed in these stories is the aftermath. The smoke, the damage, the weeks of cleanup that follow.
Anyone who wants to understand what displaced families actually face after a fire like this can read about what families discovered when they returned to smoke-damaged homes after the Aspen Acres fire and found the cleanup had just begun.

Why This Matters
The “no warning” detail is not just a headline. It is a public safety issue federal investigators have been raising for years.
The NTSB has noted that unlike smoke alarms, natural gas alarms are not currently required in most U.S. homes, even in homes with active gas service.
The NFPA reports an average of 4,200 gas-ignited home fires annually in the United States, with serious explosions causing property damage, injuries, or fatalities estimated between 286 and 400 per year.
These incidents do not always start inside either. Sometimes the source is entirely outside the home, and residents have no reason to suspect anything.
Families dealing with fire threats that originate from outside their own walls is something covered in depth in this piece about a family left homeless after a neighbor’s fireworks caused a fire in Fort Worth.
And fires that destroy homes are not always accidental. The FBI joining the investigation after a historic Indiana home was set on fire in a suspected hate crime is a reminder that residential safety threats take more than one form.
The families on Gregson Avenue got out. That is not always the outcome when there is no warning.

Wrapping Up
A Millcreek neighborhood went to bed Sunday night with yellow tape where a home used to stand. The investigation is still open.
