Maui
The August 2023 Lahaina fire was the deadliest US wildfire in over a century. Carriers responded by tightening wildfire underwriting statewide — every Maui address now faces stricter scrutiny than it did two years ago. West Maui and Upcountry bear the highest pressure, but no zone is exempt.

Stacked risk types facing West Maui coastal properties: wildfire exposure and direct coastal flood hazard simultaneously
Maui's wildfire exposure was well-documented before August 2023. HWMO — the Hawaii Wildfire Management Organization — had published community risk ratings for West Maui and Upcountry corridors for years. Carriers knew the data. What the Lahaina fire changed was the actuarial weight assigned to that data. The event established a loss precedent that reinsurance markets had to reprice immediately.
Upcountry Maui — Kula, Makawao, Pukalani — sits in elevated wildfire risk corridors. Grass and scrub fuel loads are significant. Trade winds accelerate through the central valley. HWMO risk ratings for these communities now factor directly into carrier underwriting decisions. Properties in high HWMO zones are seeing either non-renewal notices or significant premium increases at renewal.
West Maui — Lahaina, Kaanapali, Napili — faces stacked risk: wildfire exposure from inland fuel corridors combined with coastal flood hazard from FEMA-designated flood zones along the shoreline. A property in this corridor may need to address both NFIP flood coverage and wildfire hardening simultaneously to retain standard market coverage.
The Lahaina fire did not confine its underwriting effects to West Maui. Carriers reassessed their entire Hawaii wildfire books in the months following August 2023. Several companies tightened underwriting criteria statewide — Maui, Oahu, Big Island, and Kauai all saw policy changes. The most visible effects on Maui are in the areas HWMO had already flagged: non-renewals in high-risk corridors and premium adjustments across the island.
Defensible space and building hardening have become underwriting factors that did not previously appear in Hawaii carrier questionnaires. Roof material, vent screening, deck construction, and vegetation clearance within 30 feet of the structure are now documented and weighed. A property with a wood shake roof and no cleared perimeter in a high-HWMO-score area is likely to face non-renewal or a forced move to the surplus lines market.
Surplus lines carriers — those not admitted in Hawaii — are writing policies that standard admitted carriers have declined. These policies are legitimate but typically carry higher premiums, no state guaranty fund backstop, and less standardized policy language. They are a valid option, but understanding what you are buying before you commit is important.
Before listing or buying a Maui property, pull its HWMO wildfire risk score and FEMA flood zone designation. These two data points determine which carriers will consider writing it and at what premium tier. A purchase contingency that includes insurability verification is not excessive — it is necessary in the current market.
For existing owners approaching renewal: if your carrier has sent a non-renewal or a premium increase of more than 40%, contact an independent broker who specializes in Hawaii surplus lines before the renewal date. The window to arrange replacement coverage is shorter than most homeowners expect. Starting 90 days out is not early.
Document all property improvements. IBHS FORTIFIED designations, new roofing materials with Class-A fire ratings, vegetation clearance photographs, and hurricane strap documentation all give a broker ammunition to negotiate with carriers on your behalf. The carrier's underwriting decision is not final until the inspection is complete — your documentation shapes that inspection.
