East Side house fire investigated as possible arson after empty gasoline cans found near origin point

Fire crews found the home fully involved; investigators examined the yard after the blaze

San Antonio fire investigators are examining the cause of a house fire on the city’s East Side after empty gasoline cans were found in a backyard near the area where the fire is believed to have started.

The fire destroyed a decades-old, wood-frame home in the 2400 block of East Commerce Street. Crews were dispatched around 5:30 p.m. and arrived to find the structure quickly consumed by heavy flames. Early concerns that someone might be inside prompted an immediate search, but no victims were located.

What firefighters encountered at the scene

Firefighters faced hazardous structural conditions as the incident unfolded. Officials reported the floor collapsed during the fire, and two tall chimneys created safety risks that limited interior access. Crews made attempts to enter the house but were forced to pull back, shifting operations to an exterior attack focused on containing the blaze and protecting neighboring properties.

Because the fire could not be fought effectively from inside, suppression took longer than in a typical residential fire, and the strategy emphasized preventing extension to adjacent homes.

Empty gas cans and a demolition order

Investigators located empty gasoline containers in the backyard close to where the fire is believed to have originated. The discovery was among the factors prompting further scrutiny of the cause, including whether the blaze was intentionally set.

After the fire, an emergency demolition order was issued due to the instability of what remained: portions of walls, part of a tin roof, and brick chimneys described as at risk of collapse. Firefighters also used hose streams to bring down the most dangerous portions of the standing masonry as the scene was stabilized.

Confirmed facts and what remains unknown

• The home was reported to be unoccupied when the fire began.

• No injuries were reported and no victims were found during the search.

• Empty gasoline cans were found in the backyard near the suspected origin area.

• The fire’s origin and cause remained under investigation at the time of the initial report.

Officials cautioned that unsafe structural conditions can rapidly change tactics, requiring firefighters to prioritize containment and scene safety over interior operations.

The investigation is expected to focus on determining where the fire began, how it spread through the structure, and whether the presence of gasoline containers is connected to ignition. Any determination of arson typically depends on the documented origin-and-cause analysis and corroborating evidence developed during follow-up work.
