The fire marshal is investigating the fire at a 4,000 square foot home Thursday night.
Multiple fire departments responded around 8:30 p.m. to the home on Glenn Abby Drive, just outside Morehead City.
Atlantic Beach Fire Chief Adam Snyder says the fire started in the garage and spread to the bonus room above. He says the rest of the big house suffered smoke damage.
The chief says the family inside managed to get out without any injuries.
So far there is no cause yet for the fire.
