Hey fellows, Update regarding old/new work. Prior to my involvement,it seems AHJ told HO at time of his permit that if any existing partitions are exposed, that wiring should be installed as new work. When I looked at job to estimate, all the walls were covered with new rock, and HO did not tell me about AHJ instruction and nether did AHJ untill time of inspection. Worse than that for HO, he insulated all exterior walls with out inspection. Ispector was peaved at HO, wanted all rock removed, but since AHJ knows of my workmanship and overall quality of other installations, he only made HO expose areas where I installed new openings, meaning only open that bay, not expose entire wall. What an ordeal, all due to not being informed by HO. Thanks for your interest. Ravin.
