First round comments always catch the same issues: incomplete Title 24 documentation, missing structural calculations, inconsistent floor plan versus elevation, and missing site survey data. Every one of these is preventable at submittal. We spend an extra day on pre submittal review and have cut our clients' average timeline by 18 days over the past two years. Separately, always submit on Monday morning. The permit intake queue resets over the weekend and Monday morning submittals enter the reviewer's queue 3 to 5 days faster than end of week submittals.
