Hawaii environmental factors
Building for Hawaii's conditions.
Hawaii home improvement is governed by Pacific shipping logistics, the worst termite pressure in the country, volcanic geology, and a corrosive trade-wind/salt-air climate. Nothing here behaves like the mainland.

What shapes a Hawaii project
Most expensive materials market in the US. Order early. Materials drive cost more than labor.
Termite-resistant materials + ongoing treatment essential. Drywood termites attack above grade.
Insurance + financing limited in Zones 1-2. Verify zone before building on Hawaii Island.
Hurricane clips, corrosion-resistant fasteners, UV-stable finishes standard. Cheap materials fail fast.
Factor solar hot water into plumbing/new-construction scope.
No frost-depth footings. Slab and post-and-pier foundations dominate.
