Hawaii Building Codes

Important: Hawaii Revised Statutes Chapter 444 requires contractor licensing through the DCCA Contractors License Board. License types include: General Engineering (A), General Building (B), and Specialty (C) with various classifications. Requirements include passing an examination, proof of financial responsibility, surety bond ($5,000 minimum), and general liability insurance. All contractors must also carry workers compensation insurance. Exemption exists for owner-occupants performing work on their own single-family residence (limited to one per year). The DCCA actively enforces licensing - unlicensed contracting can result in fines up to $5,000 per violation.

Important: Hawaii adopted the State Building Code (SBC) based on the IBC 2012 and IRC 2012 with Hawaii-specific amendments under HRS Chapter 107. The code includes enhanced requirements for: hurricane wind resistance (entire state is Exposure D), flood zone construction (FEMA coastal zones), volcanic hazard areas (Lava Zones 1-2 on Big Island), and corrosion-resistant materials (salt air). Each of the four counties (Honolulu, Maui, Hawaii, Kauai) enforces the state code with additional local amendments. Honolulu has the most extensive local amendments. Building permits are required for all construction work.

Important: IRC Section R105 establishes when building permits are required. Roof replacement (re-roofing) generally requires a building permit in jurisdictions that enforce the IRC or an equivalent building code. Hawaii adopts codes statewide, so virtually all jurisdictions require roof permits. Permit applications typically require contractor license verification, material specifications, and project scope description. Inspections include sheathing (if exposed) and final. IRC R105.2 exempts ordinary maintenance (minor repairs, re-attachment of trim), but full roof replacement is NOT exempt from permit requirements.
