Happy almost-Halloween! This week I've got one number that explains a lot of Oʻahu power bills, one remodel tip that can save you a trip to the permit office, and one AI tool that just became part of life for anyone planning a bigger project on the island. I'm Holly Shankleton, a REALTOR® with eXp Realty on Oʻahu.
The Hawaiʻi cost insight: what "typical" power really costs on Oʻahu
Hawaiian Electric's October 2026 filing puts the bill for a typical Oʻahu household using 500 kWh at $246.44 for the month. That's the all-in residential rate, with the fuel and other adjustments baked in.
For perspective, the Missouri Economic Research and Information Center's cost-of-living index (Q2 2026) scores Hawaiʻi utilities at 207.3, where the U.S. average is 100. In plain terms, our utilities run about twice the national average.
If you're buying, ask the seller for a few recent electric bills, and look at whether the home has rooftop solar or a battery. It can make a real difference to your monthly budget. Want to see how your own household stacks up? Plug in your numbers at the Hawaiʻi cost-of-living calculator.
The Oʻahu remodel tip: a kitchen refresh may not need a permit
Here's one a lot of homeowners don't know. Honolulu generally requires a building permit for electrical, plumbing, or wall changes. But a cosmetic kitchen refresh (refacing or replacing cabinets, new countertops, and swapping appliances in the same spot, with no electrical or plumbing work) is exempt under the Revised Ordinances of Honolulu §18-3.1(b)(11).
What might it cost? The 2025 Cost vs Value report puts a midrange minor kitchen remodel at $28,458 nationally. Using Honolulu's historical cost premium of about 15% from the last Honolulu-specific Cost vs Value report (2015), that's roughly $32,700 here. Treat that as a floor, since shipping and labor have gone up since then.
One more thing: Hawaiʻi law (HRS §444-2) only exempts very small jobs, under $1,500, from contractor licensing. For anything bigger, make sure your contractor is licensed. You can run your own kitchen or bath numbers in the Oʻahu remodel cost estimator.
The AI tool: CivCheck, Honolulu's AI permit pre-checker
If your project does need a permit, meet CivCheck. Since September 1, 2026, Honolulu's Department of Planning and Permitting (DPP) requires this AI pre-screening tool for residential new construction, additions, and alterations (single-family, two-family, and duplex), plus ADUs and ʻohana units.
The good news: it's free, and DPP says applications prepared with CivCheck reach a permit decision 55% faster on average (32.5 days versus 73 days). DPP's director described it to Hawaiʻi Public Radio as "like TurboTax for preparing your building permit plans." It checks your plans and documents against city codes before you submit, and it can even read handwritten submissions.
A few things to know. It doesn't replace the City's official review or guarantee approval. Quick Permits, solar, fences, retaining walls, and general electrical or plumbing work don't use it. And DPP suggests starting a few weeks before you plan to submit. Details are on DPP's Getting Started With CivCheck page.
