According to the Los Angeles County Fire Department, the Wheel fire, which burned west of Palmdale, has charred 500 acres and was 70 percent contained.
Authorities said the blaze began as a structure fire on Wagon Wheel Road just before 1 p.m. when a trailer and barn caught fire.
"It's grown quite a bit in a very short time," said Michael Taylor of Agua Dulce.
About 250 firefighters have responded to the scene, along with eight aircraft, including two Super Scoopers.
"The good news is a lot of these houses have great brush clearance," said Capt. Mark Savage of the Los Angeles County Fire Department.
One resident said some of the brush in the area had not seen a fire in 50 years.
No mandatory evacuations have been ordered.
One firefighter injury was reported, as well as one civilian injury. No details were released on the injuries.
"It's very frightening. We've had fires out here many times in the area around us, but this is the closest we've seen in 11 years," said Erin Taylor of Agua Dulce.
