What plans and documents you must submit with a building permit

(a) With each application for a building permit, three sets of plans, specifications, calculations, construction inspection requirements, and other data shall be submitted. One set of plans shall be submitted to and left with the State department of health. Construction inspection requirements are as defined in § 18-4.6 . Exception: the building official may waive the submission of plans, specifications, calculations, construction inspection requirements, etc., if the building official finds that the nature of the work applied for is such that reviewing of plans is not necessary to obtain compliance with this code. (b) No plans or specifications are required for repair or replacement work, unless requested by the building official. (c) Plans for single- or two-family dwellings are not required to show plumbing piping plans or diagrams unless requested by the building official. (d) All plans and specifications relating to work that affects the public safety or health and for which a building permit is required shall be prepared by or under the supervision of a duly licensed professional engineer or architect as required by HRS Chapter 464. (e) All plans for retaining walls 5 feet or more in height shall be prepared, designed, or approved by a duly licensed architect or engineer in the structural or civil branches. (f) Electrical plans and specifications shall bear the approval of either a duly licensed electrical engineer, or a duly licensed architect or engineer qualified in such work by experience; provided that if the demand load of the proposed installation is less than 30 kilovolt-amperes, the approval of an engineer or architect shall be required only if the building official so directs. )
