Sounds like a common problem we have with building inspectors out here.
Plans approved.
Build. Inspect. Inspector prefers another method. "But..it meets code and is approved this way" Inspector "Ya, but I've never liked that method and this one will last longer." Debate...make the change in a day, argue for 3 days. Screw it, change it. 3 days later, inspector arrives, different one. "Hmm, hey that's not per plan".
