The brush fire, which also leveled six outbuildings, was 90 percent contained on Saturday, according to Cal Fire. No injuries were reported.
It began about 1:15 p.m. Thursday near Los Alamos Road and Liberty Road, then went on to engulf a residence on a ridge. Witnesses near the scene said they could hear the sound of propane tanks exploding at residences in the distance.
As a precaution, all 20 campuses within the Murrieta Valley Unified School District were closed Friday, and all school events and activities were canceled. All evacuation orders were lifted by noon Friday.
