Fire crews responded to a fire that broke out in a Santa Maria residence Tuesday morning.
The fire broke out before 8 a.m. at a mobile home on the 1700 block of South Thornburg St., officials said.
The residents said that they were leaving the house when they heard a pop and immediately saw fire in the living room.
By the time crews arrived, three or four minutes later, the flames had spread through the whole structure.
A family of five has been displaced by the fire.
The four family members in the home at the time were able to escape without injuries, officials said, but one of the family's pets, a dog, passed away in the fire after crews were unable to resuscitate it.
"They exited safely and they had a couple dogs with them," Santa Maria Fire Marshall Jim Austin told KSBY. "Sadly, we did lose one dog."
Fire crews remained at the home mopping up the area for several hours.
"Nearly all their belongings were either consumed or damaged in the fire," Austin said.
The Red Cross was notified about the fire and will assist the family, fire officials say.
The fire's cause is still under investigation.
"This time of year, you're always looking at Christmas tree-type fires or decoration-type fires," Austin said. "That was not the case here. The origin is the center of the structure, which is mostly in the living room."
Officials say the fire appears to be accidental in nature.
