10:35 PM: In South Delridge, crews are at a house fire in the 9000 block of 21st SW, just reported as under control and almost out.

10:39 PM: According to SFD, the fire started “in a wall,” according to the first report they got. They’re still checking on some possible hot spots in the attic. SFD says no injuries have been reported.

TUESDAY MORNING UPDATE: SFD public-information officer Kyle Moore says they’ve determined the fire was accidental:

The occupant of the home was working on plumbing when the heat from the plumbing work ignited the wall and extended into the attic space.

At 10:10 p.m., a call came in the Fire Alarm Center reporting flames coming from the wall of a home in the 9000 block of 21st Avenue SW. Engine Company 11 arrived to find smoke coming from the roof of the two-story home. The firefighters used an attack hose line to knock down the flames while the first in Ladder Company searched the residence for occupants and then headed to the roof to cut holes in order to vent the smoke and heat.

Firefighters discovered the fire inside the walls of the home. The flames extended up the walls into the attic. Crews removed two walls and brought down ceilings in order to completely extinguish the flames. It took approximately 30 minutes to completely knock down this fire.

Three occupants safely evacuated the home and there were no reported injuries. The damage estimate is $65,000 to the structure and $5,000 to the contents.
