Firefighters made a stand near the freeway about 10:45 a.m., stopping the flames from jumping the 101 after they originated at Mureau Road and Mountain View Drive.
Meanwhile, the Los Angeles County Fire Department said residents of the Hidden Hills community should be set to leave if evacuation orders were ordered. Those orders never came.
The Fire Department canceled its second-alarm assignment about 11:15 a.m., and units remained at the scene to tackle hot spots.
No injuries or structural damage were reported.
The official cause of the fire was unknown, but it was burning amid extreme red flag conditions in the region.
