April 18—A Seattle Fire Investigator determined a North Seattle House Fire was an accidental fire. The most likely cause was determined to be the spontaneous combustion of oils that leaked and mixed in a basement master bedroom.

The first 911 call came in at 7:15p.m. The caller reported hearing a loud sound and seeing light gray smoke coming from the basement of a home located in the 13000 block of 7th Avenue NW. The first arriving engine company found smoke in the basement of the 1-story home. The lone occupant safely evacuated the house before firefighters arrived.

It took crews about 15 minutes to completely extinguish the flames.

There were no reported injuries.

The damage estimate is $50,000 to the structure and $20,000 to the contents.
