A space heater placed too close to a bed caused the fire at the single- story home on Billow Drive, between Skyline Drive and San Felipe Street, around 2:45 a.m., according to the San Diego Fire-Rescue Department.
Fire crews had the blaze knocked down in about 20 minutes, SDFRD Capt. Joseph Amador said.
The American Red Cross was summoned to assist five adults and a child displaced by the fire, authorities said.
