9:02 AM: Just after 4 am, a briefly big Seattle Fire response was sent to the 8800 block of 38th SW [vicinity map] in Upper Fauntleroy. SFD spokesperson Kaila Lafferty says the fire was on the stairs and deck of a townhouse – one of several relatively new homes on the block – but firefighters “got it out quickly and started releasing crews.” No injuries. And no word yet on the cause.

11:57 AM: We have that now, from spokesperson Lafferty: “The cause was determined accidental. The fire was in an unoccupied duplex and was likely caused by faulty or damaged electrical wiring inside of wall smoldering through the stud and joist spaces. It spread to the stairwell, leading to a rooftop patio.”
