Three cars were destroyed in a fire at a National City auto repair shop, officials said Friday.
Firefighters from National City, Chula Vista and San Diego responded to the fire on Highland Ave at 18th Street at 3:15 a.m.
Smoke filled the garage and flames were contained to the left side of the building, officials said.
Battalion Chief Mark Beveradge told NBC 7 every commercial fire gets four fire engines, two trucks and two battalion chiefs.
When it's a business like an auto repair shop, the firefighting efforts are intensified.
Crews have a heightened awareness to fires in gas stations and auto repair shops because of all the flammables and hazardous materials often found inside these businesses, he explained.
But Beveradge said the design of the building helped firefighters in this case.
“With a concrete building, it buys you a little bit more time with extension of the fire going to another property or building,” he said.
Fire investigators are looking into the cause of the fire.
