A call came in about a fire in the 3700 block of Underwood Drive at 2:43 a.m., according to San Jose fire senior dispatcher Brenda Jaime.
One firefighter was injured in the four-alarm blaze.
San Jose fire Capt. Mary Gutierrez said the firefighter fell through the roof at 3:08 a.m. and was then hospitalized in stable condition.
The firefighter has yet to be released from the hospital, she said.
The fire started on the bottom floor and spread upward to the attic, Gutierrez said.
All residents were evacuated and the American Red Cross is assisting the 17 displaced resident this morning, Gutierrez said.
Gutierrez said a resident on the first floor said they had left a candle unattended, which the captain said is a probable cause of the blaze.
The fire was knocked down at 3:38 a.m., however, some crews are still at the scene this morning, according to Gutierrez.
Seventy firefighters, including mutual aid assistance from the Santa Clara County Fire Department, responded to the fire this morning, Gutierrez said.
