What these prices are: Each one is the U.S. price for that project, adjusted for what construction workers earn in Hawaii. Materials cost about the same in every state. Across the U.S., building material prices are up 10.1% from a year ago (see material prices). So the difference between states is mostly pay. These are numbers to plan with, not quotes, and big cities can differ. Get two or three written bids from local contractors.

What each trade earns in Hawaii

Average yearly pay for each trade in 2025, and how it compares with the U.S. average. Pay is the main reason prices in Hawaii differ from the rest of the country. The numbers come from U.S. government wage data.

Hiring a contractor in Hawaii

In Hawaii, general contractors get a state license from the Hawaii Contractors License Board. Ask for the license number and look it up.

  • Check the license before you sign. Use the official Hawaii license lookup to check that the license or registration is current. Also ask for a certificate of insurance (proof the contractor is insured) that names you as the certificate holder.
  • Get two or three written bids for the same work. Comparing them tells you more than any one price. It is also the quickest way to spot a quote that needs a closer look.
  • Keep the deposit small, and pay as the work gets done. Many states limit how big a deposit can be. A request for most of the money up front is a common warning sign.
