Hawaii Building Permit Timelines & Delays
Hawaii has among the most heavily regulated land-use environments in the nation, and approval delay is a leading driver. UHERO's Hawaii Housing Factbook finds the state's median building-permit processing time runs more than triple the national average — a constraint it ties directly to suppressed housing supply.
Hawaii permitting, the figures
The key published figures for this jurisdiction — each cited to its official source.
What the data shows
Hawaii's median residential permit processing time runs more than three times the national average, a delay UHERO links directly to constrained housing supply (UHERO Housing Factbook, 2026).
In the first half of 2025, median processing reached roughly 394 days for single-family and 585 days for multifamily permits in Honolulu, the state's slowest county (UHERO Housing Factbook, 2026).
The state estimates building-permit delays cost Honolulu's private sector about $202 million across 2022–2023, roughly 7% of total private permit value (Hawaii DBEDT, 2025).
After modernization, Honolulu DPP cut average residential code-review time from six months or longer in May 2024 to about nine days by November 2024 (Honolulu Star-Advertiser, 2024).
Most delay accumulates before technical review
The data points to the same lever everywhere: most delay accumulates before technical review, in completeness and resubmittal cycles. Permittable's Permit Review Diagnostic checks your plans against applicable codes and common reviewer issues before you submit — so your package is more likely to clear on the first pass.
Hawaii permitting: FAQ
How long does a building permit take in Hawaii?
It varies sharply by county. UHERO's 2026 Housing Factbook reports 2025 median single-family processing times of 127 days in Hawaii County, 186 days in Maui County, 309 days on Kauai, and about 394 days in Honolulu. The statewide median runs more than triple the U.S. average (UHERO Housing Factbook, 2026).
Why are Honolulu permits so slow?
State analysts cite administrative bottlenecks, including a DPP staff-vacancy rate around 25% as of mid-2024 and outdated processing systems (Hawaii DBEDT, 2025). Hawaii also carries the nation's highest land-use regulatory burden, with more than twenty ordinances added to Honolulu permit issuance between 2012 and 2023 (Hawaii DBEDT, 2025).
Have permit times improved?
Yes, recently, for residential review. Honolulu DPP reported average residential code-review time fell from six months or longer in May 2024 to about nine days by November 2024, with the pending backlog dropping below 10,000 (Honolulu Star-Advertiser, 2024). A 2024 City Auditor review credited the progress but found delays still persisted.
How fast is Lahaina rebuilding after the 2023 wildfire?
Maui County stood up an expedited disaster-recovery permitting process, and by early July 2025 about 420 building permits had been issued for Lahaina rebuilds (Hawaii Public Radio, 2025). UHERO data shows expedited Maui disaster permits in 2025 cleared in a median of about 83 days, versus 379 days for standard permits (UHERO Housing Factbook, 2026).

Figures use different methodologies and are not strictly comparable: UHERO reports median application-to-issuance times by county and year, DBEDT reports averages for 2022–2023, and DPP figures isolate code-review time (not total permit time) at specific dates in 2024. UHERO notes Honolulu data after June 2025 was unavailable due to the city's new permitting-system rollout.
