Construction Cost FAQ for Hawaii
Why is building in Hawaii so expensive?
Isolated shipping, very high labor rates, expensive land, and strict codes combine to make Hawaii the most costly state to build in, near $209 per square foot.
Are materials more expensive in Hawaii?
Yes. Almost all materials are imported and shipped long distances, so freight and markup add substantially to costs.
Does building in Hawaii require special structural design?
