Slab on grade garage?
Most garages are built with footings and stub walls or thickened slabs of concrete. Building codes require this to protect the siding and framing materials from rot and water damage. Anything less is structurally unsafe and prone to rot. Pictures would be helpful.
Be safe, Gary
