1:02 PM: Big response headed to a fire call at an apartment building in the 9000 block of 20th SW (map). First arrivals are seeing some smoke from the building’s fourth floor, per scanner traffic. We’ll have updates from the scene shortly.

1:10 PM: Fire’s under control, per scanner.

1:13 PM: Added photo from the scene. Smoke no longer showing from the building.

1:22 PM: Fire’s reported out. Still some traffic trouble in the area (Delridge/20th). We’re expecting to talk soon to the incident commander for more official information.

1:30 PM: Seattle Fire spokesperson Kyle Moore is there and we should be talking with him soon. We’ve also heard from the neighbor who says he called 911 to report the fire, Jeff at eGreen Landscaping, whose business is right next door on Delridge: “We reported it to 911 and then ran up and alerted the building manager, who hit the building fire alarm.”

1:35 PM: Moore says the fire was confined to a bedroom in one apartment. No injuries. (Update: Here’s video of his briefing:)

Investigators are working to figure out how it started; all the other residents will be allowed to go back inside. The woman who lived in the burned unit wasn’t home at the time; her cat might have been inside, and fire crews were looking for it.

5:23 PM UPDATE: Seattle Fire has just published a report here – saying the fire has been ruled accidental, and was “likely” started by a lamp in the bedroom. The report also notes that damage is estimated at $45,000 – and that the resident was reunited with her cat.
