Hawaii climate & cladding drivers
- IECC climate zone: 1A
- Dominant residential cladding: Vinyl panel — dominant low-budget retrofit choice in non-WUI, non-coastal corridors
- Hurricane wind tier: High wind exposure — 140 mph+ design wind on coastal counties
- Wildland-urban interface (WUI) cladding rule: Regional WUI overlay — ignition-resistant cladding required in mapped fire-hazard zones
- Salt-air corrosion zone: High-corrosion coastal — stainless or hot-dipped galvanized fasteners required within 3,000 ft of saltwater
Hawaii licensing & permits
- License status: Statewide license required
- License board: Hawaii Department of Commerce & Consumer Affairs — Contractors License Board (B General Building or C-12 Drywall/C-49 Siding specialty) (official site)
- Permit: county building permit required for full re-side and envelope sheathing work
How siding replacement costs vary in Hawaii
State-specific code or insurance rule: Hawaii Contractors License Board issues a C-49 Cladding/Siding specialty license distinct from the B General Building credential — and unique to Hawaii, every contractor must additionally pass an island-specific examination on trade-wind wind loading, volcanic vog corrosion mitigation, and tsunami inundation zone construction requirements, with Maui and Hawaii County imposing additional WUI-overlay cladding restrictions in lava-flow recovery zones.
