The one-alarm blaze was first reported at a home at 14170 Woodhaven Drive at around 3:55 a.m., according to the San Jose Fire Department.
Arriving units reported the home to be fully engulfed in flames, Kouns said. An active power line was reportedly seen draped over a truck at the front of the residence.
While one fire crew attacked flames from the front, another crew went to the rear of the structure to rescue people trapped inside.
Two people and two dogs were successfully rescued, Kouns said.
Once the fire was partially knocked down, crews entered the home and found one person who had died from smoke inhalation.
Further details regarding the victim were not immediately available.
The fire was declared under control at 5:02 a.m.
Crews remained at the scene at 6 a.m. conducting an investigation.
