One person sustained minor injuries in a two-alarm fire that occurred at a condominium in the 6700 block of 139th Avenue Northeast in Redmond Saturday evening.

A fire alarm alerted Redmond Fire Department (RFD) to the condominium fire a little after 7 p.m. Redmond police and fire arrived on scene to find a fully engulfed second floor unit and the fire rapidly spread to the floors above. Crews from Bellevue and Kirkland fire departments also responded to the scene.

Redmond police and other residents assisted in evacuating the building. Two subjects had to be carried from the building; one resident and one Redmond police officer each carried an elderly female away from the rapidly spreading flames.

The one injured person was evaluated and treated on scene.

A total of 18 fire apparatuses with 46 fire personnel battled the fire for about an hour. At this time it appears that there is severe fire damage to at least three units and other fire, smoke and water damage to additional units.

Julie Beard, spokesperson for the Redmond Police Department said building residents are still displaced and are estimated to be until Wednesday when the power can be isolated to the undamaged units. Once the power is restored to those unites, residents can move back in, she said.

“Red Cross is assisting with a temporary shelter as we speak for displaced residents who could not make other arrangements,” Beard said.

She added that at least three units are “completely uninhabitable” and the surrounding units have smoke, water and/or fire damage and are likely going to be uninhabitable as well for an extended period of time.

The cause of the fire appears to be food left cooking unattended. Beard said the fire investigator’s initial on-scene investigation Sunday showed that the cause of fire appears consistent with witness accounts: Oil was left in a pan on a stove and it caught fire.

“The resident discovered the fire and was unable to put it out,” Beard said.

RFD personnel praised the usage of a monitored fire alarm, which prompted a fast response to a fire that could have caused major injury and even more significant damage if not stopped so quickly.
