The fire broke out just before 1 a.m. inside the storage units at Chain Lake Self Storage.
"I didn't want to accept it until I know for sure," said Kim Carmody, who was between moves and had all her belongings in a unit there. "Furniture, toys, my kids stuff -- literally everything."
Because the storage units are metal, crews could not easily pour water on the blaze from above using ladder trucks and instead had to use saws to cut holes into the siding for their hoses.
Fire Chief Jamie Silva said it was too dangerous for firefighters to enter the building and they fought the fire from the outside.
After sunrise, crews brought in a heavy excavator to tear apart the burned sections of the building so firefighters could ensure the fire is completely extinguished.
About 70 storage units were destroyed. While many lost household items, for Tracy Corner, the fire was a blow to her income as she kept her inventory there for her eBay busniess.
"Will it cut into my finances? For years to come," she said. "Because that's probably about two years of inventory sitting in there. You think you're doing good, you think you're ahead of the ballgame, and no, not now."
The cause of the fire is under investigation.
