Question: A plumbing contractor has just completed the rough-in plumbing for a new multi-story commercial building. Before concealing any pipework within walls or ceilings, what type of inspection is typically required by the Authority Having Jurisdiction (AHJ) in accordance with provincial plumbing regulations?

Answer options:
