Investigators are calling it "undetermined" right now because of the extensive damage.
It happened in the Woodlands subdivision of Branson.
Fourteen people are displaced, but fortunately no one was hurt.
The fire started about 10 a.m. Wednesday and quickly tore through the 12-unit condominium complex.
The building was engulfed in heavy smoke and flames.
The Red Cross is helping the people who lost their homes.
