UPDATE: FEB. 15, 4:45 p.m.
The Honolulu Fire Department Fire Investigator has classified the cause of the fire as undetermined.
An investigation revealed that structure was the site of a previous fire. The building had a partially collapsed roof, lacked electricity and was uninhabitable.
No injuries were reported in the most recent incident, though a home adjacent to the structure suffered extensive water damage due to fire fighting efforts.
Damage estimates are not yet known.
Honolulu firefighters extinguished a fire that broke out at an abandoned house in Waipahu Sunday night.
Ten units with 35 firefighters responded to a 911 call for a structure fire at 94-337 Paiwa St. at about 10:30 p.m. When they arrived, fire crews saw heavy smoke and flames coming out of the single-story residence, the Honolulu Fire Department said.
The fire spread to a home next door, forcing the occupants to evacuate.
Firefighters brought the fire under control just before 10:50 p.m. and extinguished it at about 11:25 p.m. No injuries were reported.
The cause of the fire and a damage estimate has yet to be determined.
The fire department noted the abandoned structure sustained damage in a fire a few months ago.
The American Red Cross is assisting 12 neighbors — nine adults and three children — who were displaced by the fire.
