What is different about seawall repair in Hawaii
Shipped materials and a small contractor pool make Hawaii the most expensive state in the country for nearly every project; lava and coastal hazard overlays add review on the Big Island.
Owner-builder: Owner-builder permits allowed with an exemption affidavit. Seawall Repair generally requires a licensed contractor to pull the permit, even where owner-builder status is available.
