Honolulu Building Permits
Building permits in Urban Honolulu, the urban core of the City and County of Honolulu, are issued by the Department of Planning and Permitting (DPP), not a separate municipal building department. DPP publishes the building permit requirements and uses HNL Build and ePlans for online filing and plan review, and certain simple qualifying work may use the instant online permit path. Codes follow the State Building Code Council's statewide framework with county amendments, so confirm the active edition before filing.
