Firefighters responded to a call from just outside the city of Selma at Nebraska and DeWolf avenues after 8 a.m. When they arrived, they saw heavy smoke and fire coming from the home.
Investigators say one family was sleeping when the fire started. One person saw smoke and alerted several adults and children inside. Everyone made it out safely.
The family told investigators there were no working smoke detectors in the home, and fire officials say it's very important to have them in your house.
"Obviously the earlier you're aware of it, everybody can get out safely. The smoke is very, very toxic, and this family is very lucky to get everybody out OK," said Capt. Ryan Michaels with Cal Fire Fresno County Fire.
The Red Cross was also contacted to help the family. It's unknown what caused the fire, or what area of the home it started in. The investigation is ongoing.
