A DPP permit search in Honolulu is free and runs through two city websites: HNL Build for permits filed from August 2025 onward, and DPPWeb for older building permits that were closed by July 31, 2025. Both are searchable by Tax Map Key or street address, and both are reachable from the Department of Planning and Permitting’s permitting page.1Department of Planning and Permitting. Permitting If the record you need predates the digital systems or isn’t showing up, you can request it directly from the department under Hawaii’s public records law.
What to Have Ready Before You Search
The search works best when you start with the Tax Map Key, or TMK. This nine-digit identifier pinpoints a parcel’s location on Oahu and breaks into five parts: island number, zone, section, plat, and parcel.2Hawaii State Office of Planning and Sustainable Development. TMK Help Every parcel in Hawaii has one, and the DPP portals rely on it more than any other identifier.
If you don’t know the TMK, look it up on the Honolulu Real Property Assessment Division’s website, which includes a public records search where you can enter a street address.3City and County of Honolulu. Real Property Assessment Division Match the address to official records exactly, including any unit or apartment number. A small spelling difference in a street name can return no results.
If you already have a permit application number from a project you filed or are tracking, keep it handy. Entering it goes straight to that record instead of pulling the full history of the parcel.
Where to Search Online
Honolulu split its permit records across two systems during a 2025 transition, so the first question is always which one holds your record.
HNL Build for August 2025 and Later
Permits filed from August 2025 onward live in HNL Build, the city’s current Online Permitting, Licensing, and Application Portal. The portal covers more than building permits. You can also look up zoning permits (including zoning adjustments, waivers, and special district permits), site development permits, coastal area permits, and planning applications such as zone changes.4City and County of Honolulu. Online Permitting, Licensing, and Application Portal Enter the TMK digits in the designated fields or search by address, then click into any matching record for the full detail.
DPPWeb for Older Closed Permits
Building permits that were closed as of July 31, 2025 sit in a legacy system called DPPWeb, which the city keeps as a read-only research archive.1Department of Planning and Permitting. Permitting This is where most historical permit data lives for properties with any renovation or construction activity before the HNL Build switch. The interface works the same way: TMK or address in, results list out. On a property with decades of history, expect a long list.
If you’re reviewing a property comprehensively, check both. The DPP’s permitting page links to each.1Department of Planning and Permitting. Permitting
Reading the Results
Each record carries a status label showing where the permit stands:
- Issued means the plans were approved and the contractor is authorized to build. Work should be underway or about to begin.
- Finaled means every required inspection passed and the city considers the work complete and code-compliant. This is the status you want on any past project.
- Expired means the holder didn’t complete the work or call for inspections in time. The work may or may not have been done, but the city never signed off.
- Withdrawn means the applicant cancelled the permit before finishing.
- Under review means the plans are still being evaluated. No construction is authorized yet.
Alongside the status, each record shows the job value (the estimated construction cost on the application) and a work description, such as an electrical panel upgrade, a bathroom remodel, or a new lanai. Together those fields tell you what the city authorized, what it was supposed to cost, and whether anyone confirmed it was built correctly.
One warning about reading the search as proof of anything: most structural, electrical, and plumbing work on Oahu requires a permit, with narrow exemptions for things like short fences, small sheds, painting, and minor repairs below set dollar thresholds.5Department of Planning and Permitting. Building Permit Requirements A clean history on a property that visibly has additions or renovations is not a clean bill of health. It means the city has no record, which is a different thing.
When Records Aren’t Online
Older paper records, or files that involve sensitive planning data, may not appear in either portal. For those you file a public records request.
Hawaii’s Uniform Information Practices Act, codified in Chapter 92F of the Hawaii Revised Statutes, gives the public the right to inspect and copy government records that aren’t otherwise restricted.6Office of Information Practices. Uniform Information Practices Act (Modified) Under the UIPA rules, an agency must respond within ten business days by granting access, denying it with an explanation, or sending written acknowledgment that extenuating circumstances require more time.7Office of Information Practices. How to Request a Record
To start, submit a Request to Access a Government Record form to the DPP. You can reach the records team at (808) 768-8277, or visit the main office at 650 South King Street in Honolulu or the satellite office at 1000 Uluohia Street in Kapolei.8Department of Planning and Permitting.

Most requests are fulfilled with physical copies or digital scans once the archive is located.
What to Do With an Open Permit
A permit search earns its keep when it turns up something you weren’t expecting. If a record shows “issued” or “expired” status on work that looks finished, that’s an open permit, and the city never confirmed the work meets code.
This matters most during a sale. Hawaii’s seller disclosure form asks whether improvements were built without permits, whether any permits were never finaled, and whether work was done under an owner-builder permit.9Oahu Real Estate. Seller’s Real Property Disclosure Statement Sellers have to answer, but the form itself warns that sellers may not know about every problem and that buyers should pull their own public records.
As a buyer, you have a few practical options when you find an open permit: ask the seller to close it out before closing, negotiate a credit to cover the cost of bringing the work into compliance, or ask that part of the sale proceeds be held in escrow until the permit is resolved. Title companies sometimes flag open permits late in the transaction, and in that case extending the closing date to give the seller time to resolve the issue is often the simplest path. Don’t treat an open permit as a paperwork glitch. The work may have failed an inspection, or it may never have been inspected at all.
If you’re the owner, running a search on your own property before you list is the cheapest version of this problem to solve. The consequences of unpermitted work on Oahu are real: a stop-work order carries a misdemeanor penalty of up to $2,000 per day or up to one year of imprisonment for violation, and the owner is barred from any new permits until all violations are cured and fines paid.10American Legal Publishing Code Library. Honolulu Revised Ordinances 18-7.5 – Stop Work Order Civil fines for administrative violations can reach $5,000 per violation plus $5,000 per day of ongoing noncompliance.11Honolulu City Council. Bill 52 (2023), CD1 Insurers may deny claims tied to unpermitted work or decline to renew a policy if they discover it during a claim. Appraisers and lenders discount or exclude the value of unpermitted additions. In some cases the city can require the work to be torn out. After-the-fact permits almost always cost more than permitting the work the first time, since finished surfaces often have to be opened for inspection.
