A mobile home in Oceanside was completely destroyed by a fire Thursday afternoon, according to the Oceanside Fire Department.
Officials said the fire began around 3:50 p.m. in Space 59 of the San Luis Rey Mobile Home Park at 200 North El Camino Real.
When crews arrived, they found a double-wide mobile home engulfed in flames. The fast-spreading fire began threatening adjacent mobile home units on all four sides, officials said.
Once the home was fully-involved, it ignited trees and storage buildings between the units.
The intense heat also melted the plastic and aluminum siding off trailers adjacent to and across the street from the engulfed mobile home.
Officials said it took a total of 27 firefighters, five engines and two ladder trucks about an hour to fully extinguish the flames.
According to authorities, the mobile home was occupied by a woman in her mid-80s and her grandson, who were able to escape the fire along with their pet cat.
The woman was transported to Tri-City Hospital for observation. The grandson did not need medical attention. No other injuries were reported.
Authorities said American Red Cross was requested to assist the displaced occupants, as their home and all of their belongings were destroyed.
Fire investigators determined the fire to be accidental, caused by faulty electrical wiring in the old mobile home. They said damage is estimated at $102,000.
