Authorities are investigating what ignited a fire at a vacant residence in Turlock that left the home in charred ruins.

The fire extended to vegetation surrounding the home, but firefighters were able to stop the flames from spreading beyond that point.

The Turlock Fire Department was dispatched to the 4400 block of West Main Street to reports of a residential structure fire at 9:47 a.m. on Tuesday.

While responding to the scene, dispatch advised fire crews that the building was reported to be fully involved, meaning there was heavy fire involvement of the entire building, said Turlock Fire spokesman Capt. Jason Bernard.

Additional resources were requested to the scene.

The first firefighters to arrive found the single-story home completely engulfed in flames.

“The fire was rapidly extending into an adjacent field and trees, as well as high voltage power lines with an actively arcing electrical wire on the ground,” Bernard said.

Due to the extent of the fire spread, crews declared a defensive mode of operation and attacked with 2 ½-inch hose lines, ultimately containing the fire to the structure and the vegetation surrounding the property.

Turlock Fire responded to the incident with three engines, Squad 32, a battalion chief, two division chiefs and a deputy fire chief. Additional resources included an engine plus three mutual aid water tenders and the Turlock Rural Fire Department Fire Chief. In total, 24 firefighters were on-scene while one additional battalion chief and engine provided for city coverage.

The building was unoccupied and no injuries were reported for this incident.

The cause of the fire is currently under investigation by the Stanislaus Regional Fire Investigation Unit. Any inquiries or information regarding this incident can be addressed by contacting the fire department at (209) 668-5580.
