A high-rise fire in Waikiki today which caused an estimated $30,000 damage to a 25th-floor unit was started by a discarded cigarette, according to Honolulu Fire Department investigators.

The fire in unit 2501 of the Kaimana Villa condominiums at 2550 Kuhio Ave. was reported at 12:11 p.m. and contained by 12:20 p.m., said Honolulu Fire Department Capt. Earle Kealoha.

Investigators determined the fire started on the unit's lanai, said Kealoha. No one was at home when the fire started but a resident told investigators he had been smoking on the lanai and discarded the cigarette in a plastic container.

Damage to the structure was estimated at $20,000 and $10,000 to contents.There were no injuries and the fire was confined to one unit.
