The fire that damaged a home on Hidden Cove Road Thursday evening has been ruled accidental, Bainbridge Island Fire Marshal Luke Carpenter said Friday afternoon.

The assessment was preliminary; Carpenter said the final determination on what sparked the blaze will be determined next week.

Bainbridge Island firefighters were called to the home at 8191 Hidden Cove Road shortly after 6 p.m. Thursday, and found flames shooting through the roof of the three-story house.

Carpenter, who is also an assistant chief with the Bainbridge Island Fire Department, said firefighters entered the home and knocked down the biggest part of the fire, then retreated due to concerns about the structural integrity of the home.

No one was home at the time of the fire, but fire investigators interviewed the homeowners Thursday night after they got home.

The investigation continued Friday morning.

No one was hurt in the two-alarm fire. Dispatchers also sent fire engines and tenders from the Poulsbo Fire Department and North Kitsap Fire & Rescue to the fire, and all told, 34 firefighters responded to the fire.

Hidden Cove Road was closed for approximately five hours Thursday night as firefighters fought the fire.
