Police and firefighters responded to the scene, the exterior of the Banana Republic store at Fifth Avenue and Pike Street, at about 6 a.m. after receiving reports of a person trapped on a roof, said Kyle Moore of the Seattle Fire Department.
The man, believed to be in his 20s, had leg injuries that prevented him from moving off the 15-foot-high awning above the store's exterior doors and display windows.
Crews then called in a ladder truck and were able to lower the man down off the awning using a specialized stretcher called a "Stokes basket."
The man was then taken to Harborview Medical Center in stable condition.
"We don't know how he got up to that area, but he certainly sustained injuries that are indicative of someone that had fallen, although he was still alert, oriented and stable when we transported him," Moore said.
Some observers said it appeared that the man had fallen on the awning from a ledge higher up on the exterior of the building, but it's not clear how or why he got up to the ledge.
