3 PM UPDATE: Now reported to be under control. One possible injury.

3:07 PM UPDATE: Via Twitter, SFD describes the house as “vacant.” That’s borne out by this DPD record for the address that SFD has logged for the fire – a complaint made and investigated less than a month ago.

3:20 PM UPDATE: Nobody hurt, we’ve confirmed with SFD. Fire investigators are en route to look into the cause. The fire is mostly out except for some smoldering in the walls. Neighbors tell us it’s been a problem house for a year or so.

3:35 PM UPDATE: Update – we’ve since been told a firefighter suffered a hand injury and has been taken to the hospital.

5:58 PM UPDATE: As mentioned in comments, fire and police investigators have been there; we went back over for photos.

Still no official word on the cause, but the police presence confirms they are investigating the possibility of arson.

MONDAY UPDATE: Lt. Sue Stangl from SFD says investigators determined that this fire was “set,” and so Seattle Police are investigating. Damage to the house is estimated at $100,000, and $5,000 to its contents.
