I'd also see if you can run the hose along the house, where its tucked at the back of a step or porch step-up and then only crosses in front of a garage door. Or, run a Gutter Downspout or Leader drain pipe over to the garden area or even go to a Rain Barrel setup on that side if you can't get a Plumber in to put a Hose Bibb on that side of the house.
- But yes, you can run the hose over the driveway, preferably in an enlarged control joint of the driveway. PVC could then hold up fairly long and be cheap and easy to replace as needed, but I think I'd go for Heavy Galvanized Pipe instead (like the threaded pipe you see in the Home Improvement Stores).
- Though under the driveway would be ideal, you'll probably want to enlist a Sprinkler Company with its specialty tools and methods to do that. As, I'm not too keen on cutting a slot in the driveway to drop in a pipe. Yes, control joint cracks typically go all the way through the slab, but the slabs aren't actually detached and still have quite a lot of frictional retention of each other.
