How Hawaii's Building Permit Process Actually Works (DPP, Maui, Hawaii County, Kauai)
Hawaii has four county permit systems, four different web portals, four different fee structures, and four different timelines. Honolulu DPP gets the worst reputation but isn't actually the slowest in 2026. Here's the working contractor's view of what each county is like, what the timeline really is, and where the steps people miss live.
The four counties at a glance
| County | Department | Portal / records | Typical residential timeline |
|---|---|---|---|
| Honolulu (Oahu) | Department of Planning & Permitting (DPP) | honolulu.gov/dpp · permit search via "Honolulu Permits" | 6–14 weeks for typical SFR remodel; 14–24 weeks for new SFR |
| Maui (Maui, Lanai, Molokai) | Department of Planning + DPS Building Division | MAPPS at mapps.mauicounty.gov | 10–20 weeks for typical SFR remodel; 18–32 for new SFR. Post-fire West Maui rebuilds prioritized. |
| Hawaii (Big Island) | Planning + Public Works (Building Division) | EPIC at papaaukahi.hawaiicounty.gov | 4–10 weeks for typical SFR remodel; 8–16 for new SFR. Generally the fastest. |
| Kauai | Planning + Public Works | Click2Gov at egov.kauai.gov | 6–12 weeks for typical SFR remodel; 12–22 for new SFR. |
The Honolulu DPP walkthrough
Most Hawaii residents deal with DPP, so it's worth understanding in detail. The basic flow:
- Pre-application meeting (optional, free). Schedule via DPP's online portal. ~2 weeks lead time. Worth it for any project that touches structure, MEP, or the building envelope.
- Design + drawings. Architect or designer-of-record, structural engineer if needed, surveyor for any lot work, MEP if mechanical/plumbing/electrical changes. 4–10 weeks for residential.
- Application submitted via DPP's online portal. You'll need: site plan, floor plans, elevations, structural drawings, energy compliance form (REScheck), Title-24 calcs, sometimes drainage report.
- Plan-review queue (the long part). DPP routes to: structural, MEP, fire, ADA, drainage, planning (zoning compliance), historic if applicable. Each reviewer takes 2–4 weeks. They review in parallel ideally; in practice some lag.
- Comments / corrections. Almost always comes back with revisions on first submission. 1–4 weeks to revise + resubmit.
- Permit issued. Pay fees, pull the permit card, construction begins.
- Inspections. Foundation, framing, rough plumbing, rough electrical, insulation, drywall, mechanical, final. Schedule via DPP online; inspector arrives 24–72 hrs after request.
- Certificate of Occupancy. Issued after final inspection passes. 2–4 weeks.
Honolulu permit fees (residential, ballpark)
- Building permit (under $50k value): ~$200–700
- Building permit ($50k–$250k value): ~$700–2,400
- Plan review fee: 50% of permit fee
- Mechanical / plumbing / electrical sub-permits: $80–400 each
- Inspections: included in permit fee
For a $125k mid-range kitchen remodel, expect $1,500–2,800 in total permit fees. New construction can run $4–12k+ depending on scope.
Maui — slow but improving
Maui Planning + DPS Building Division earned the slowest reputation pre-2023 — review queues commonly ran 16–24 weeks. After the August 2023 Lahaina fires, the county priority-tracked rebuild permits and accelerated streamlining for everyone else as a side effect. 2026 timelines are 30–50% faster than 2022.
MAPPS replaced the old KivaNet system in 2022 and is reasonably workable now — search by TMK or address. Fee structure is similar to Honolulu but slightly higher.
Hawaii County (Big Island) — fastest
Counterintuitive given the island's size and remote-ness — but Hawaii County's Planning + Public Works has the leanest queue. The EPIC / Papa'Aukahi portal is functional and responses generally come back inside 3 weeks. The county also has a robust over-the-counter permit program for minor work (re-roofs, water heater swaps, water-only plumbing) — same-day approval if you bring complete plans.
Caveat: Hawaii County REQUIRES a structural engineer's stamp for any project in lava zones 1, 2, or 3 (which is most of lower Puna and parts of Volcano Village). That's a pre-application reality, not a permit-stage discovery.
Kauai — middle of the road
Kauai Planning + Public Works has manageable queue times (6–12 weeks typical) but a smaller plan-review staff means expedited review isn't really an option — the queue is the queue. The Click2Gov portal works but is the least modern of the four counties.
Kauai's specific quirk: shoreline setback enforcement is the most aggressive in the state. Any new construction within 40 feet of the high-tide line goes to the County Planning Commission for a public hearing — adds 2–4 months even if approval is likely.

Energy code compliance (Title-24 / IECC)
Every county requires energy-compliance documentation for new construction and most major remodels — REScheck or COMcheck output, plus a manual sign-off from the designer-of-record. Submitting without it is the most common reason for first-pass rejection.
HRS Chapter 196E (PV requirement)
Hawaii state law requires solar water heating in new single-family dwellings unless an exemption applies. The exemption process needs to be filed at permit application — a lot of homeowners discover this at framing inspection, which is too late.
Drainage / stormwater plan
Any work that increases impervious area beyond a threshold (varies by county) requires a drainage plan. Common gotcha on driveway expansions, patios, and pool decks.
Tree removal permits (Honolulu)
Honolulu protects "exceptional trees" — typically requires a separate Arborist Advisory Committee permit before removal. Not part of the building permit. People discover this when DPP refuses to issue the building permit until the tree question is resolved.
Cesspool conversion (statewide, by 2050)
Hawaii's 2050 cesspool conversion mandate (Act 125, 2017) requires every cesspool statewide to be replaced with septic or sewer connection. When you pull a permit on a cesspool-served parcel today, the county will often condition the permit on starting the conversion. Plan for $25–55k of additional work.
Working with DPP — practical tips
- Pre-application meetings work. 30 minutes of free time with a planner saves you a 4-week back-and-forth on a contestable point.
- Submit a clean first application. Resubmissions go back to the end of the queue. One thorough review beats three half-baked ones.
- Use a designer who knows the local jurisdiction. A mainland architect's first Hawaii project will trip on every island-specific code variation. Pay for the local guide.
- Track your application status. All four counties have status portals. Check weekly. Don't assume silence means progress.
