Firefighters were able to quickly extinguish the fires. The structures were searched, but there was nobody inside any of them.
No injuries to firefighters or civilians were reported. Damage is estimated at $4,000.
The cause of the fires is under investigation.
It was the second time this week that firefighters had to head to Moccasin Flats. Another structure caught fire early Tuesday morning. There were no injuries in that case, which caused about $2,000 damage.
