The cause of a fire that started in a 4,800-square-foot abandoned home early this morning in Lahaina is undetermined, Maui Fire Department officials said. 

The fire started just after 1 a.m. and extensively damaged about half of the three-bedroom, two-bathroom, older single story home at an estimated cost of $200,000.

Officials said it was brought under control 25 minutes after the first firefighters arrived at 233 Lahainaluna Road to find the structure 50 percent involved in flames.

No injuries were reported, and the fire was extinguished at 6:19 a.m.
