Fire Department investigators determined that an early morning fire Friday at a Hawaii Kai house was caused by unattended smoking material that ignited a mattress.
The fire was in a studio apartment attached to a three-bedroom house at 663 Kaumakani St.
Firefighters responded at 1:08 a.m. and brought it under control in 20 minutes. The fire was extinguished at 2:12 a.m.
The resident of the studio apartment was not home at the time. Two people were in the main house but were not threatened by the fire.
The fire caused moderate damage to the bedroom of the apartment, but did not spread to other parts of the apartment or to the main house, the fire department spokesman said. Damage was estimated at $15,000.
