A fire of unknown origin caused an estimated $300,000 worth of damage to a Clairemont home Wednesday and left two residents in need of emergency shelter.
The non-injury blaze in the 3700 block of Mount Acadia Boulevard was reported shortly after 8:30 a.m., according to the San Diego Fire-Rescue Department.
Crews arrived in roughly three minutes and 45 seconds of the call, finding flames leaping from the roof of the single-story house, SDFRD spokesman Maurice Luque said.
"There was a huge plume of black smoke over Clairemont," he said.
Two people inside the residence when the blaze erupted were able to escape unharmed. It took a contingent of about 30 firefighters less than five minutes to get the flames under control.
The American Red Cross was called in to help the two adult residents arrange for interim lodging.
Due to the extent of the damage, investigators were unable to determine the cause of the blaze, which appeared to have erupted in a back bedroom, according to Luque.
The monetary losses were set at $250,000 to the structure and $50,000 to contents.
