Hurricanes / coastal tropical storms
Risk profile
Hawaii's hurricane risk is lower frequency but high consequence, with Central Pacific storms bringing coastal surge, extreme rain, landslides, wind damage, and island-wide utility disruption.
Home prep before the event
Before hurricane season in Hawaii, confirm your evacuation zone, roof age, shutter or impact-covering plan, garage-door bracing, gutter drainage, sump or backflow protection, and generator placement. Photograph the roof, exterior, mechanical equipment, and contents before a named storm enters the forecast cone.
During-event safety
During the storm, evacuate when ordered and do not wait for water at the door. If sheltering, stay in an interior room away from windows, keep phones charged, avoid candles, and keep generators outside, downwind, and far from openings.
Post-event recovery
After the storm, photograph roof, siding, interior water, spoiled contents, and serial numbers before permanent repairs. Start temporary drying and tarping when safe, keep receipts, watch for unlicensed storm chasers, and wait for permits before structural, roof, electrical, or generator work. Use FEMA's HI page at https://www.fema.gov/locations/hawaii if a federal disaster is declared, and monitor Hawai'i Emergency Management Agency at https://dod.hawaii.gov/hiema/ for state recovery centers, debris rules, shelter updates, and mitigation programs.
Code references
Code reference: coastal wind and flood repairs usually rely on the state or local IBC/IRC edition, ASCE 7 wind loads, local floodplain ordinances, and NFIP substantial-improvement rules. Verify the authority having jurisdiction before replacing roof, windows, structural connectors, or electrical equipment.
Wildfires and smoke
Risk profile
Hawaii wildfire risk is tied to dry leeward slopes, invasive grasses, trade-wind gusts, steep access roads, and neighborhoods where evacuation routes are limited.
Home prep before the event
Before red-flag weather, clear the 0-to-5-foot zone next to the house, clean gutters, screen vents, move firewood and patio cushions away, label the gas shutoff, and keep defensible access for engines. Schedule roof, deck, siding, and ember-vent repairs before smoke season.
During-event safety
During evacuation alerts, leave early if instructed, close windows, move combustible items from decks, and do not block roads for fire crews. If smoke is heavy, run filtered air indoors and avoid outdoor cleanup until air quality improves.
Post-event recovery
After a wildfire, wait for official reentry, document structures and contents before ash cleanup, wear respiratory protection, and follow local hazardous-debris instructions. Ask the insurer about smoke, additional living expense, and code-upgrade coverage before signing rebuild contracts. Use FEMA's HI page at https://www.fema.gov/locations/hawaii if a federal disaster is declared, and monitor Hawai'i Emergency Management Agency at https://dod.hawaii.gov/hiema/ for state recovery centers, debris rules, shelter updates, and mitigation programs.
Code references
Code reference: wildfire construction rules are usually local or state WUI adoptions, fire-code amendments, defensible-space ordinances, and ignition-resistant material requirements. Ask the building department and fire district before changing vents, decks, siding, glazing, or access roads.
Flooding
Risk profile
Hawaii flooding is often fast and steep, with tropical downpours, clogged culverts, flash flooding in gulches, landslides, and coastal wave runup.
Home prep before the event
Before heavy rain, check the FEMA flood map, photograph contents, lift stored items, test sump pumps, add battery backup where practical, clean drains, extend downspouts, and ask whether the sewer line needs a backwater valve. Keep flood insurance documents separate from standard homeowners coverage.
During-event safety
During flooding, move up, not out through water. Do not drive across covered roads, enter a flooded basement with energized circuits, or run pumps if the discharge adds water against the foundation. Follow local evacuation and boil-water notices.
Post-event recovery
After floodwater recedes, do not start demolition until photos, high-water marks, and insurer instructions are recorded. Standard homeowners policies usually exclude flood; use NFIP or private flood coverage if you have it. Substantial-damage letters can trigger elevation or repair limits. Use FEMA's HI page at https://www.fema.gov/locations/hawaii if a federal disaster is declared, and monitor Hawai'i Emergency Management Agency at https://dod.hawaii.gov/hiema/ for state recovery centers, debris rules, shelter updates, and mitigation programs.
Code references
Code reference: mapped flood work depends on FEMA Flood Insurance Rate Maps at https://msc.fema.gov/portal/home, local floodplain ordinances, NFIP substantial-damage rules, IRC R322/IBC 1612 where adopted, and ASCE 24 guidance at https://www.fema.gov/node/american-society-civil-engineers-flood-resistant-design-and-construction.
Extreme heat / heat domes
Risk profile
Hawaii heat events are often humid, with trade-wind disruptions, wildfire smoke, salt-air corrosion, and island outages making indoor cooling and ventilation more important.
Home prep before the event
Before peak heat, service AC equipment, replace filters, clear condenser airflow, seal major attic leaks, shade west-facing glass where practical, and plan a cooling location for outages. Confirm generator and transfer equipment are permitted and never run portable generators indoors or in garages.
During-event safety
During extreme heat, treat indoor temperature as a safety condition. Move vulnerable residents to cooling centers if the home will not cool, drink water, avoid oven use, and call 911 for confusion, fainting, or suspected heat stroke.
Post-event recovery
After a heat event, document AC failure, electrical damage, spoiled medicine, and any emergency lodging or cooling costs. Check utility, LIHEAP, weatherization, and local repair-assistance programs before replacing equipment, and keep medical or outage notices with the claim file. Use FEMA's HI page at https://www.fema.gov/locations/hawaii if a federal disaster is declared, and monitor Hawai'i Emergency Management Agency at https://dod.hawaii.gov/hiema/ for state recovery centers, debris rules, shelter updates, and mitigation programs.
Code references
Code reference: heat resilience upgrades are typically governed by local mechanical, electrical, and energy codes, including adopted IECC or ASHRAE 90.1 provisions. Generator interlocks, transfer switches, and new circuits require NEC-compliant permitted work.
