The Honolulu Fire Department is investigating the cause of a Sunday morning fire at a residential townhome in Mililani.

HFD sent seven units staffed with 23 personnel to the fire near the 94-1000 block of Lanikuhana Avenue after receiving a 911 call at about 7 a.m.

Firefighters said they saw light smoke coming from the exterior of the two-story townhome. Firefighters proclaimed the blaze extinguished around 7:09 a.m. after entering the building and finding an extinguished kitchen fire.

The building’s occupants were able to self evacuate and were assessed by Emergency Medical Services, but refused treatment.

HFD is investigating the fire to determine the origin, cause, and damage estimates.

HFD provides the following safety tip: Use smoke alarms, which are essential to detecting fires. Working smoke alarms save lives because they provide more time to escape.
