Maui fire investigators determined that fireworks caused a fire that destroyed a Kihei house Friday night. The manner was considered accidental.

A Maui fire official said 14 family members were displaced when the house was destroyed by the fire, but all managed to escape uninjured.

Firefighters from the Kihei and Wailea station responded to the blaze at 210 Oe St.

The two-story, 2,400-square-foot single-family home as well as the contents of the backyard were fully involved when they arrived.

The fire began in the backyard and quickly spread to the house, causing $400,000 damage to the structure, $50,000 to its contents, and $70,000 to vehicles and equipment stored in the backyard, Maui fire spokesman Lee Mainaga said in an e-mail.

The American Red Cross assisted the family members with food, clothing and accommodations for a couple of nights.
