That is a good point.....I think that because your garage does not share a wall with your house, it might be considered detached.
Why not underground? It's actually pretty easy to run conduit under a slab....make a probe with a piece of PVC....hook the water hose to one end....glue a cap on the other....drill some holes....drill right through the dirt. It's actually kind of fun....especially if you have kids....they love the mud.
