Mercer Island, Bellevue and Eastside fire departments responded to a fire in a multi-family residential structure at the 8000 block of SE 33rd Place at 11:53 p.m. on Monday.

According to a press release from the Mercer Island Fire Department, the fire was intentionally started with an accelerant. It was determined to be isopropyl alcohol.

A suspect was arrested by the Mercer Island Police Department (MIPD), booked into King County jail and charged with first degree arson. The investigation is ongoing.

Arson is a Class A felony, said MIPD Sgt. Jeff Magnan. The case was filed with the King County Prosecutor’s office.

The suspect is a 35-year-old resident and part-owner of the building, which houses four condos. The fire was set in the hallway, and firefighters arrived to find it fully charged with smoke and approximately six to eight lineal feet of flames on the carpeted floor.

The complex was occupied when the fire started, but was safely evacuated when fire units arrived. A total of nine fire apparatus were dispatched to the fire.

Responders arrived on scene within minutes after the fire began. Mercer Island firefighters were able to extinguish the fire after about five minutes, with no extension to other areas or buildings, using a single attack hose line.

The building and contents sustained limited damage, estimated currently at $5,000-$10,000.
