A fire of undetermined origin damaged a house off Leesburg Road east of Columbia around noon Sunday.
When the fire started, there were two adults and two children at home, and they heard some type of noise and when they looked around, they found a fire in the garage, Columbia interim fire chief Aubrey Jenkins said.
The fire quickly spread to the garages attic, he said.
Investigators are trying to determine what caused the blaze at the single-story, vinyl-siding house at 7126 Patricia Drive, he said. The fire caused an estimated $50,000 in damage.
