The Bellevue Fire Department is estimating a $2.1 million home up for sale on the 3100 block of 110th Avenue Southeast sustained at least $750,000 in damage during an early morning fire Monday.

Firefighters responded to the three-story home around 12:30 a.m., and believe the fire started on the first floor in the back of the house. It spread up to the upper two levels of the home and into the attic space, said Fire Lt. Richard Burke, “Which led to lots of air and lots of space for free burn.”

The home was unoccupied at the time of the fire, and no one was injured. One firefighter did fall through the third floor into the second, but Burke said he was able to hold onto a fire hose.

“We had a firefighter who went through the floor, from Floor 3 to Floor 2. He was not injured and he stayed on the scene,” he said. “He pushed through an area where he’d been working and down he went. He kind of rode the hose down, held onto the fire hose and landed on his feet.”

Initial reports were that a gas-powered fire pit in the back of the house may have been the cause of the fire, but Burke said nothing is definitive at this time as the investigation remains active.
