Authorities are lifting evacuation orders for residents of some 200 homes who were forced to flee after the fire broke out in Monrovia Saturday.
City officials say the blaze was sparked by equipment used by a gardener working the backyard. Flames spread to the hillside behind the residence, scorching about 175 acres.
The fire is 50 percent contained.
The city's fire chief said dry, thick brush on steep terrain made the fire difficult to contain. However, the lack of evening wind is helping firefighters get a handle on the blaze.

Residents of about 200 homes were forced to evacuate Saturday after a brush fire erupted in the San Gabriel Mountain foothills east of Los Angeles, authorities said.
The fire was sparked by equipment used by a gardener working the backyard, said Jennifer McLain, a city spokeswoman. Flames spread to the hillside behind the residence, scorching about 175 acres.
The fire was not immediately threatening homes, but authorities ordered evacuations as a precaution, fire Chief Chris Donovan told KABC-TV. It sent a huge smoke cloud that could be seen across the San Gabriel Valley.
The blaze was 10 percent contained, with full containment expected Sunday.
Donovan said dry, thick brush on steep terrain made the fire difficult to contain. Fire officials were concerned about evening winds that could shift the fire downhill toward homes, but the lack of wind slowed the fire's growth by nightfall.
"I am comfortable with the situation and the lack of wind," Donovan said.
Dozens of firefighters, aided by water-dropping helicopters and an air tanker, were battling the blaze. One firefighter suffered a heat-related injury.
As the Monrovia fire burned, a four-acre brush fire ignited across town near Interstate 405, forcing the closure of southbound lanes for at least an hour and causing traffic to back up for miles. That fire has been contained.
