How Does the Honolulu DPP Plan Review Process Work?

HNL Build is the online permitting platform that replaced the legacy Posse system, consolidating permit tracking so a project's phases share one record instead of separate tracking numbers. Account registration with email verification is required, and electronic plan submittal is the standard path. Questions about ePlans uploads go to the department's dedicated ePlans support email, and the permit center can be reached by phone for application questions. The prescreen gate is where most submittals stall or sail through. Reviewers check plan format, scale, dimensions, and required documents before any engineer or architect reviewer sees the design. Common returns include missing bar scales, un-dimensioned plans, absent shoreline certifications on coastal lots, and incomplete structural or civil documentation. A clean prescreen pass is the cheapest schedule insurance in the whole process, because a submittal returned at prescreen has not yet entered the technical review queue.

Multi-agency review means several reviewers look at the same set of plans for different code chapters, and their comments arrive as a combined correction list. The design team's response should address every comment in writing, cloud the changes on the drawings, and resubmit a complete package, because partial responses generate a second correction cycle on items that could have closed in the first. OTR-60 compresses this for eligible single-family and two-family projects by limiting the agencies to one review cycle, with compliance verified at inspection. Structural submittals get the smoothest reviews when the calculations, the geotechnical report, and the drawings tell the same story. Lateral system, foundation type, and design loads in the calculations must match what is drawn and what the geotechnical engineer recommended. The AHJ alone decides what is approved, and the design team confirms the current review timelines with the department, since workload-driven backlogs change the schedule math more than any design choice.
