The one-alarm fire was reported shortly before 11 a.m. at a residence on Orlando Drive. A fire crew on a medical call in the area saw smoke rising from the home, fire Captain Steve Alvarado said.
He said firefighters made an aggressive interior attack on the blaze and had it controlled by 11 a.m.
A 24-year-old man, who had been sleeping when the fire started, was the only one home and was stirred awake by the sound of glass breaking. The man realized there was smoke and jumped out the closest window, Alvarado said.
He was not injured, Alvarado said.
"He's very lucky," Alvarado said. "Not everybody will be as fortunate as this guy."
Alvarado said the smoke detectors in the house were not functioning properly.
The blaze caused about $50,000 to $100,000 in damage.
The cause of the fire is still under investigation, Alvarado said.
