Honolulu Bill 41 NUC renewal walkthrough: ROH §21-4.110 step-by-step

Bill 41 passed Honolulu City Council in 2022, codified as Revised Ordinances of Honolulu (ROH) §21-10.1. It collapsed a tangled legacy framework into something simple on paper: outside the resort district, short-term rentals (under 30 days) are only legal if the unit holds a Non-Conforming Use Certificate (NUC) issued before the ordinance took effect.

NUCs renew annually under ROH §21-4.110(j). The renewal is procedural — there's no quota, no waiting list. But it's also unforgiving: a single missed renewal cycle permanently retires the certificate. You can't reapply.

This is the step-by-step playbook for the 2026 cycle.

Before you start: confirm you actually hold a NUC

Honolulu Department of Planning & Permitting (DPP) issued NUCs only to units that could document continuous <30-day rental use prior to October 2019 (when the original moratorium took effect). Verify yours at dpp.honolulu.gov — search by TMK or address.

If you don't hold one, you have two legal paths outside the resort zone:

• 30-day-minimum rentals — these are not regulated as STRs at all, and don't require any special certificate
• Bed & Breakfast Home permit (BBH) — owner-occupied only, separate permit class under ROH §21-4.110-1, limited annual issuance

Step 1 — Pull together your renewal packet (60+ days before anniversary)

The NUC renewal application requires the following documents, per ROH §21-10.1(b) and (c):

• Current NUC certificate — your previous year's certificate is the renewal eligibility proof
• Liability insurance certificate — $1M general liability minimum, naming the property and operator (ROH §21-10.1(b)(7))
• Smoke + CO detector recertification — annual per HRS §132-9.6 + ROH §16-2.1
• Property tax payment proof — current real property tax must be paid in full
• Operator + emergency contact information — 24/7 phone for guest issues / neighbor complaints
• Tax ID display attestation — proof that GE Tax + TAT IDs appear in every listing per ROH §21-10.1(c)

Skip the COI step and you'll get a 30-day cure notice. Skip the tax-ID-in-listing step and the inspector who finds it can refer the case to DPP enforcement immediately.

Step 2 — File via the DPP online portal (45 days before anniversary)

DPP shifted NUC renewals fully online in 2024. The portal accepts the packet electronically; a confirmation email arrives within 72 hours.

Filing fee for 2026 is roughly $500-650 depending on unit class — published at dpp.honolulu.gov/fees. Pay by ACH or credit card at submission.

Submitting 45+ days early matters because the standard review window is 30 days, but contested cases (HOA objections, neighbor complaints, prior infractions) can stretch to 60+ days. If your anniversary is May 15 and you file May 1, you have no slack.

Step 3 — Survive the compliance audit (random)

DPP audits roughly 1 in 5 NUC renewals. The audit is a desk review — they pull your Airbnb / VRBO listings, check for:

• NUC number displayed in every active listing (including secondary platforms you may have forgotten about)
• GE Tax + TAT IDs displayed alongside the NUC number
• Local 24/7 contact phone number on the listing
• Listing description that matches the NUC's permitted use (e.g., if your NUC is for a 2-bedroom unit, the listing can't advertise 4 bedrooms)
• Maximum-occupancy disclosure consistent with the certificate

Failing the audit doesn't auto-deny renewal, but it triggers a 14-day cure notice. You fix the listing, submit screenshots showing compliance, and the renewal continues.

Step 4 — Pay the OTAT + GET + TAT to keep current

Honolulu's OTAT (Oahu Transient Accommodations Tax) at 3% layers on top of the state TAT (10.25%) and GE Tax (4.5% including the Oahu surcharge through 2030). Filing cadence is monthly for most operators, due the 20th of the following month.

• GET: 4.5% (HRS §237-30 + ROH §3-1.1 Oahu surcharge through 2030)
• TAT: 10.25% (HRS §237D-6)
• OTAT: 3% (ROH Ch. 3 §3-1.1, effective 2021-12-14)

What happens if you miss the renewal window

Bill 41 is unforgiving here. ROH §21-4.110(j) treats a lapsed NUC as permanently retired — there is no reinstatement procedure, no late-filing fee, no appeals path for missed-window. The unit reverts to the underlying zoning (which outside the resort district means 30-day minimum).

The pragmatic implication: set the calendar reminder for 90 days before your anniversary, not 30. Most operators who lose their NUC do so because they got a notice 45 days out, intended to handle it "next week," and lost the unit in their portfolio that pays for itself in 2-3 months of operation.
