A wildfire west of Temecula's city limits destroyed one structure and burned up to 35 acres Tuesday, Oct. 6, before firefighters stopped its forward spread.

The Carancho Fire was reported at approximately 6 p.m. near Carancho Road and Frens Road in unincorporated Riverside County, near De Luz and the San Diego County line. Cal Fire/Riverside County Fire Department Captain John Clingingsmith told Patch that two aircraft were requested to assist ground crews early in the response.

The fire grew quickly in what incident commanders described as medium to heavy fuels with a moderate rate of spread. At one point, fire officials estimated the blaze could reach 150 acres, according to Valley News.

Cal Fire deployed a large response: 139 personnel, 24 engines, two helicopters, one bulldozer, three hand crews, one water tender and 10 additional resources, Valley News reported. Air tankers flew suppression missions as conditions allowed.

The North County Fire Protection District sent crews to assist with the firefight.

No evacuations were ordered. No civilian or firefighter injuries were reported.

Cal Fire posted on X that one structure had been destroyed and that crews were making good progress on the ground. Acreage estimates shifted throughout the evening. Patch reported 20 acres at 7:30 p.m., later remapped to 15 acres by 8:35 p.m. Cal Fire's own update listed 35 acres at 0% containment. By 10 p.m., the fire had reached 10% containment, according to the Sacramento Bee.

Cal Fire later confirmed the fire's forward spread had been stopped at approximately 15 acres, according to a News Flash Media report. Crews were expected to remain on scene into Wednesday, Oct. 7, to strengthen containment lines and extinguish hot spots.

The cause remained under investigation as of Tuesday night.

The De Luz area, a rural stretch along the Riverside-San Diego county line, was the focus of a $500,000 Riverside County investment in October 2025 to install helicopter dip tanks near De Luz and La Cresta through Rancho California Water District. Those assets were expected to be operational in 2026. Whether they were used during the Carancho Fire response is not confirmed.
