The cost of a residential building permit on Maui is based on the estimated cost to build the home, not on the square footage. You can find a lot of good info on the Maui County website, including a fee schedule which tells you how to estimate the cost of your permit. Or, call a builder on Maui who will tell you that to build a typical 2,000 sf home it will probably cost you about $2,300-$2,400 for your building permit, electrical permit, and plumbing permit.
