A DPP permit search in Honolulu is done through two free online portals run by the city’s Department of Planning and Permitting: HNL Build for permits filed from August 2025 onward, and DPPWeb for building permits closed on or before July 31, 2025. Both let you look up building, zoning, and land-use records for any parcel on Oahu using the property’s Tax Map Key or street address. Anything older, sealed, or otherwise not available online can be pulled through a formal records request.
What to Have Ready Before You Search
The identifier the system relies on most is the Tax Map Key, or TMK. It’s a nine-digit number that pinpoints a parcel’s location on Oahu through five components: island, zone, section, plat, and parcel.1Hawaii State Office of Planning and Sustainable Development. TMK Help Every parcel in Hawaii has one, and having it in front of you before you open the portal is the difference between a two-minute lookup and a frustrating afternoon.
If you don’t know the TMK, you can look it up by street address on the Honolulu Real Property Assessment Division’s site, which links to a public property records tool.2City and County of Honolulu. Real Property Assessment Division Match the address to official records exactly, including unit or apartment designations. A misspelled street name or the wrong abbreviation can return no results even when records exist.
If you’re checking on a specific project rather than a property’s full history, the permit application number gets you straight to that record.
Which Portal to Use
Honolulu’s permit records are split between two systems by date, and picking the right one is the single most important step. Both are linked from the DPP’s permitting page.3Department of Planning and Permitting. Permitting For a full property history, you’ll usually need to check both.
HNL Build for Permits from August 2025 Forward
Permits filed on or after August 2025 live in HNL Build, the city’s current Online Permitting, Licensing, and Application Portal. It covers more than building permits. You can also search 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 use the property address. Click into any matching record for details.
DPPWeb for Older Closed Permits
Building permits that were closed as of July 31, 2025, are in DPPWeb, a legacy system the city keeps online as a read-only research archive.3Department of Planning and Permitting. Permitting Most historical permit data for properties with renovation or construction activity predating the HNL Build transition lives here. The search works the same way: TMK or address. A property with decades of activity may return a long list, so give yourself time to scroll.
Reading a Permit Record
Every record carries a status label showing where the project sits in the city’s approval pipeline. Those labels matter, especially if you’re looking at a property you might buy.
- Issued. The department approved the plans and authorized construction. Work should be underway or about to start.
- Finaled. All required inspections passed and the city considers the work complete and code-compliant. This is the status you want to see on any past project.
- Expired. The permit holder didn’t complete the work or request inspections in time. The work may or may not have actually been done, but the city never signed off.
- Withdrawn. The applicant formally cancelled the permit before finishing.
- Under review. The department is still evaluating the plans. No construction is authorized yet.
Beyond status, each record shows a job value (the estimated construction cost on the application) and a work description summarizing what was planned, 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 boundary worth naming: an empty search result isn’t proof the property is clean. Not every home improvement on Oahu requires a permit (small fences, low retaining walls, painting, floor coverings, and certain minor repairs are exempt), but most structural, electrical, and plumbing work does.5Department of Planning and Permitting. Building Permit Requirements If you can see obvious additions or structural changes and the search turns up nothing, that gap is the finding.
Requesting Records That Aren’t Online
Older paper records, and certain sensitive planning files, may not appear in either portal. For those, submit a formal records request.
Hawaii’s Uniform Information Practices Act, in Chapter 92F of the Hawaii Revised Statutes, gives the public the right to inspect and copy government records not otherwise restricted by law.6Office of Information Practices. Uniform Information Practices Act (Modified) Under the UIPA rules, an agency has ten business days to respond, either by granting access, denying it with an explanation, or acknowledging in writing that it needs more time.7Office of Information Practices. How to Request a Record
File a Request to Access a Government Record form with the DPP. You can reach the records team at (808) 768-8277, 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 come back as physical copies or digital scans once the archived materials are located.
Why the Search Matters in a Real Estate Deal
A permit search does work a home inspection can’t. Hawaii’s seller disclosure form asks specifically whether any 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 everything and that buyers should pull their own public records.
An “expired” or “issued” status on work that visibly looks finished is an open permit. The city never confirmed the work meets code. As a buyer, you can ask the seller to close the permits before closing, negotiate a credit for the cost of bringing the work into compliance, or ask that a portion of the sale proceeds be held in escrow until the permits are resolved. Don’t treat an open permit as pure paperwork. The work may have failed inspection, or it may never have been inspected at all.
Title companies sometimes flag open permits during closing. If that happens late in the transaction, extending the closing date to give the seller time to resolve the issue is often the most workable path.
The stakes for unpermitted work are more than an inconvenience. Violating a stop-work order is a misdemeanor punishable by a fine of up to $2,000 per day or up to one year of imprisonment, and the owner can’t apply for new permits until violations are cured and fines paid.10American Legal Publishing Code Library. Honolulu Revised Ordinances 18-7.5 – Stop Work Order Broader administrative civil fines can reach $5,000 per violation plus $5,000 per day of ongoing noncompliance.11Honolulu City Council. Bill 52 (2023), CD1 Insurance carriers may deny claims tied to unpermitted work, and appraisers and lenders often discount or exclude the value of unpermitted additions. In some cases the city can require the work be torn out.
If you own the property, running a permit search on yourself before listing gives you time to resolve issues on your own schedule. After-the-fact permits usually cost more and can require opening walls or removing finishes so inspectors can see what was built.
