A video was taken by Action News viewer J.P. Shaub as flames shot through the roof of the building and firefighters rushed to put it out.
12 cars were inside the garage. Owner Mike Riedelsheimer says he doesn't know what he'll do next. "That's a good question. I've never been down this road. I don't know. I'll find out I guess."
Investigators say the fire caused $500,000 in damage.
