A vacant office building in Sacramento's Campus Commons lit up the evening sky on Tuesday, sending a thick column of smoke over University Avenue and into nearby neighborhoods. Fire crews moved in fast but, faced with a building already heavily engulfed, quickly shifted to a defensive attack to keep crews out of harm’s way. No injuries were reported, and investigators are probing the cause, which officials are already calling suspicious.

What officials say
The Sacramento Fire Department on X reported that crews were dispatched to the 400 block of University Avenue and arrived to find a "well involved" vacant office building. Because of the intense fire conditions, incident commanders opted for a defensive strategy, keeping firefighters outside the structure while they worked to contain the flames. The department noted that no one was hurt and confirmed that the cause remains under investigation and is considered suspicious.
Scene and coverage
Footage from the scene shows heavy flames chewing through the building and a large smoke plume hanging over the Campus Commons area as engines and ladder trucks lined University Avenue. TV crews captured firefighters pouring water from a distance as the structure burned. As reported by CBS Sacramento, the building had burned before. Commercial property data from LoopNet identifies 400 University Ave as part of the Campus Commons office complex, matching the address cited by fire crews.
Why vacant-building blazes are dangerous
This fire comes on the heels of other suspicious incidents at empty properties in the region, including a similar blaze in late March that left a firefighter injured. Safety experts and federal agencies have long warned that vacant and abandoned buildings can become magnets for arson and other dangerous activity, increasing risks for both firefighters and surrounding neighborhoods, according to CDC/NIOSH.
Investigation and impact
Authorities have not given a timeline for when an official origin-and-cause report might be released, and no arrests or formal findings have been announced. Video from the scene shows crews staying on-site into the night as investigators worked around the charred structure, securing the area and starting the slow process of figuring out what sparked the fire, according to CBS Sacramento.
