Can I Get a PE Stamp for My Existing Home Plans in Hawaii?

Hawaii requires the sealing engineer to be in responsible charge of the engineering — the engineer must have exercised engineering judgment over the design. For existing plans, this means independent verification: the engineer recalculates structural elements, checks code compliance under the applicable Hawaii-adopted codes, and revises the drawings as needed before sealing. The seal must show the engineer's name, Hawaii PE number, and date. Hawaii engineers cannot seal work outside their area of competence. Honolulu, Hawaii County, Maui, and Kauai review the sealed package.

The review starts with the full drawing set: architectural, structural, foundation, and any prior calculations. The engineer checks the design against the design loads — high wind and seismic demand are the signature issues — verifies foundation design for volcanic soils per the geotechnical report, and recalculates beams, columns, foundations, and the lateral system. Corrosion protection is checked. Deficiencies get redlined; the drawings are revised until the engineer can take professional responsibility. Bring the geotechnical report, the design criteria, and any prior plan-check comments. Wind-design errors are the item most existing plans miss.

Use this checklist before engaging an engineer for existing plans: • Engineer of record holds an active Hawaii PE license, verifiable on the state roster • Plans are complete: architectural, structural, foundation, and prior calculations • Wind design verified against the current maps • Seismic design category verified for the site • Geotechnical report addresses volcanic soils for the specific site • Prior plan-check comments included so corrections aren't repeated • Engineer confirms they'll respond to plan-check corrections on sealed sheets • Seal shows name, Hawaii PE number, and date on every sealed sheet
