Arguably, a building inspector *could* consider an irrigation line as part of the home plumbing and require a plumber to pull a permit and sign off on the portion that's under the house. If it's a "patio" an not an enclosed room, it usually wouldn't be considered part of the house (no roof).

The proper way to run irrigation under a slab of any type, is typically to run conduit and run the irrigation line through it. Without enclosing it in a length of conduit, I could see them requiring a relieving arch.
