Fire investigators have classified the cause of a residential fire in Kalani Valley as undetermined.

Honolulu Fire Spokesman Capt. David Jenkins said investigators could not determine where the fire started in the home at 1541 Kalaniwai Pl. due to severe damage from the blaze.

Shortly after 4:30 p.m. Sunday, 14 companies and more than 50 firefighters responded to the fire. They brought it under control by 6:22 p.m. and extinguished it several hours later.

Occupants who were at the residence at the time were able to evacuate. No injuries were reported.

Jenkins said the home was considered a “total loss.” Damage was estimated at $400,000 to the structure and $1.26 million to its contents that included rare and original artwork.

Five other neighboring homes sustained varying levels of damage to its roofs from the fire.

Jenkins said the total damage estimate to all affected homes was estimated at more than $2 million to the structures and its contents.
