Build vs Buy in Hawaii
25-year total cost comparison, construction data, and build feasibility for Hawaii (HI).
Building in Hawaii: Overview
Hawaii presents the most challenging build environment in the nation: the highest construction costs per square foot (driven by imported materials and limited labor), lengthy permitting, and extremely scarce buildable land. However, the state has the nation's lowest property taxes and cheapest homeowner insurance, which dramatically reduce ongoing carrying costs. New construction in Oahu's Ewa Beach and Kapolei areas offers the most viable options through master-planned community development. On the Big Island, construction costs are 20-30% lower than Oahu, making Kailua-Kona a relative value play.
