Home Renovation Costs in Hawaii
Hawaii sits at a 1.45x regional cost index in our dataset. Hawaii is the most expensive state in our dataset for a straightforward reason: almost every material has to be shipped in by container, and that logistics cost stacks on top of an already high cost of living. Humidity, salt air, and periodic hurricane exposure all shorten the lifespan of roofing and exterior finishes, and homes are built on slabs rather than basements.
