Honolulu is the city most often cited in the debate over AI and building permits. Its Department of Planning and Permitting (DPP) uses a tool called CivCheck to screen residential applications before formal review. This post looks only at Honolulu: what the city launched, what the data shows, and where the picture is less flattering than headlines suggest.
What did Honolulu actually launch?
Two changes happened close together. In August 2025, the city replaced its 1998-era permit system (POSSE) with a new platform, HNL Build, at a cost of about $7.3 million, according to Honolulu Civil Beat. CivCheck, an AI-guided screening tool now owned by Clariti Software, launched in December after a six-month pilot, according to the Honolulu Star-Advertiser (the article does not state the year).
Applicants upload plans, the tool flags missing items and possible code problems, and a passing check produces an ID number that goes on the permit application. It screens applications. It does not approve them: city staff and other agencies still review and approve. Clariti Software acquired CivCheck, and Stateline reports it works with more than 20 cities, ranging from pilots to full rollouts.
Who can use it, and is it required?
In July 2026, DPP launched Priority Review, which routes complete CivCheck submissions to the prescreen stage faster. Use is voluntary for eligible residential projects. The department says CivCheck will become mandatory for eligible permits later this year, though Civil Beat reported in June that there was no firm date. Eligible work includes single-family, two-family, and duplex projects, accessory dwelling units, and ohana units. Commercial, solar, general electrical, and general plumbing work are not eligible yet. Fast processing does not guarantee approval, because other agencies such as the Board of Water Supply still review applications.
Why It Matters to You
If you are planning a single-family, duplex, accessory dwelling or ohana project in Honolulu, you can use CivCheck now to catch missing items before formal review, and a passing check gets you into the faster Priority Review lane. It is voluntary today. Commercial, solar, electrical and plumbing applicants cannot use it yet, and passing the check is not an approval.
Did permits really get faster?
| Measure | Result | Source |
|---|---|---|
| Average review time, CivCheck residential permits | 32.5 days versus 73 days for similar permits without it | Honolulu DPP, via Star-Advertiser/GovTech (19 versus 17 permits) |
| Plan review cycles | 1.4 versus 3.4 on average | Honolulu DPP, via Star-Advertiser/GovTech |
| Median wait for a new building permit | 2.5 months, down from 4 months (a 40% drop), August to April versus a year earlier | Honolulu Civil Beat analysis of DPP data |
| Residential alterations | About three months down to 40 days | Honolulu Civil Beat |
| Commercial building permits | Median 85 days before the switch, about four months now | Honolulu Civil Beat |
The 40% figure measures the whole new system, not CivCheck alone, so it is close to “nearly half” without being about CivCheck. The 73-to-32.5-day comparison is limited to a small group of CivCheck users. The DPP spokesperson called 19 completed applications “a relatively small sample” and said the efficiencies depend on broader use.
What’s the catch?
- Civil Beat reported that time spent inside CivCheck is not counted in official processing time, because the official creation date is stamped after an application leaves the tool. It also said it could not verify a DPP pilot claim of a 71% cut in prescreen delays.
- Gains were concentrated in residential permits. Commercial permits were slower under the new system, which DPP attributed to project complexity and staff vacancies (76 of 365 positions were vacant).
- Civil Beat reported that a staff survey about the HNL Build launch drew mostly negative feedback. Stateline also noted the survey. One architect told Civil Beat he saw no improvement.
- Applicants did not all benefit equally. Director Dawn Takeuchi Apuna told Stateline that applicants account for at least 50% of the back and forth in review, which is the part a pre-check targets.
Are other cities doing this?
Seattle is piloting CivCheck, and Denver signed a five-year contract of about $4.6 million for a different AI plan review product. Denver Council member Flor Alvidrez cast the lone dissenting vote, citing concerns about AI accuracy and complex zoning, according to Stateline. The Stateline reports in the sources below give the national view.
