The evacuation order for about 100 of the residences in Monrovia was lifted Saturday night after fire crews increased containment of the 175-acre blaze to 50 percent.
No structures were damaged and weather conditions were turning more favorable.
"We were really fortunate we were able to stave off the fire and protect the homes," Monrovia city spokeswoman Jennifer McLain told the Los Angeles Times.
The fire started Saturday in the back yard of a home in northwest Monrovia just days after a report warned that the relatively dry winter would mean an active wildfire season throughout California.
