Sheriff's office spokeswoman Cindi West says a man was declared dead at the scene and the other was airlifted to Harborview Medical Center. Both men were traveling in the plane.
West says no one on the ground was hurt. West says it's not immediately known where the plane took off and where it was going.
A picture tweeted by the King County Sheriff's office shows a small plane on its side and partially inside a garage.
According to the Federal Aviation Administration registry, the fixed-wing single engine plane is registered in Redmond and it seats four people.
