Cal Fire said the Rumsey Fire, located on Highway 16 north of Guinda, reached 716 acres.
The fire, sparked by a vehicle, began on Monday, as Lake County News has reported.
At one point it had as many as 350 firefighters on scene working to contain the fire, which was moving through rugged terrain dotted by oak and pine trees.
The fire destroyed two outbuildings and a residence, and at least one firefighter suffered a heat injury.
Cal Fire had no further details on the fire suppression efforts, including cost, as of Tuesday evening.
