Honolulu Fire Department investigators could not determine the cause of a fire in Maili that destroyed an apparently abandoned home.

HFD classified the cause of the fire at the single-family home at 87-794 Farrington Highway as “undetermined.” It did estimate the damages to the building at $662,000 and $250 to its contents.

The fire also affected two neighboring structures. Exposure damages to the building at 87- 802 Farrington Highway and its contents have been estimated at $31,000. The estimate at 87-105 Maipalaloa Road was $2,250.

Firefighters responded to the fire at the home, located near the intersection at Maipalaloa Road, on Tuesday night at around 11:50 p.m.

The fire department described the home as abandoned. Neighbors used a garden hose to try to put out the fire before firefighters arrived to find the home fully engulfed in flames.

Neighbors had complained for months about at least a dozen or so squatters who they observed entering and exiting the building, alleged drug use and garbage and stripped and derelict vehicles on the property.
