Can I do nightly rentals outside Waikiki or Ko Olina?

Generally no. Most residential neighborhoods are limited to 30-day or longer rentals. Limited exceptions exist such as properties with a valid Nonconforming Use Certificate (NUC).

Do I need to register my STR or renew a NUC?

If you rent for less than 30 days in an eligible zone, City registration is required. Registration is not required for specific buildings. Legacy NUCs must be renewed annually between September 1 and October 15 to remain valid.

What must my STR advertisement include?

Advertising must include your Transient Accommodations Tax ID, Property Tax Map Key, as well as the required registration or NUC identifier, per Department of Planning and Permitting (DPP) guidance. Missing or incorrect identifiers may lead to enforcement.

Did Honolulu change the minimum rental term to 90 days?

The City adopted a 90-day minimum in 2022 (Ordinance 22-7), but federal court action blocked enforcement. As of today, the City continues to regulate short-term rentals as stays under 30 days.

Oahu Vacation Rental Laws Explained for Property Owners

Stay Compliant, Informed, and Protected

Managing a rental property on Oahu means understanding Honolulu’s strict regulations around short-term and 30-day rentals. These laws define what qualifies as a short-term rental, where nightly rentals are allowed, and how owners can stay compliant while earning income from their property.

Current Rules at a Glance

Short-Term Rental (STR) definition: Any rental of less than 30 consecutive days is considered a short-term rental under Honolulu law.
Where STRs are allowed: Only in designated resort-zoned areas (such as Waikiki and Ko Olina) and limited apartment zones identified by the Department of Planning and Permitting (DPP).
Residential neighborhoods: In most of Oahu—including Kailua, Kaneohe, Hawaii Kai, Kahala, and Aina Haina—rentals must be 30 days or longer.
Registration & NUCs: Eligible STRs must register with DPP. Owners with legacy Nonconforming Use Certificates (NUCs) must renew annually between September 1 and October 15.
Advertising rules: All short-term rental ads must include the assigned registration or NUC number.
Off-Island & Out-of-State Owner Requirement: Hawaiʻi law HRS §521-43(f) and HRS §237D-4(b)/(c) requires off-island or out-of-state owners with Short-Term Vacation Rentals and Mid-Term Rentals to designate a licensed on-island agent or property manager to act on their behalf.
Taxes: Both short-term and 30-day rentals may be subject to Hawaiʻi’s GET, TAT, and Honolulu’s OTAT.
Enforcement: The City actively enforces STR compliance. Illegal rentals and improper advertising can lead to steep fines.

The 90-Day Rule and Court Decision

In 2022, Honolulu passed Ordinance 22-7, which attempted to extend the minimum rental period outside of resort zones from 30 days to 90 days. However, federal court action blocked enforcement of the 90-day rule. As of today, the law defines STRs as rentals of less than 30 days, with 30-day minimums applying across most residential neighborhoods.

Where You Can Rent Nightly

Waikiki (resort precincts): Most hotel and resort-zoned condos allow nightly or weekly rentals.
Ko Olina Resort: Properties zoned for resort use may be eligible.
Limited Apartment Zones: Some specific apartment districts designated by DPP.

Always confirm your building’s zoning and HOA rules before marketing a nightly rental.

Registration, Certificates & Compliance Checklist

Verify zoning and HOA restrictions.
Register eligible STRs through DPP’s online system.
Renew legacy NUCs annually (Sept 1–Oct 15).
Include registration/NUC number in all advertising.
Set up and maintain GET, TAT, and OTAT tax accounts.

30-Day (Monthly & Mid-Term) Rentals

For most neighborhoods, the compliant rental path is 30 days or longer. These rentals serve:

Travel nurses and medical professionals
DoD and government contractors
Remote workers and digital nomads
Families relocating to Oahu
Snowbirds escaping cold winters
Homeowners undergoing renovations

On-Island Agent & Local Contact: What Owners Must Do

Off-island owners must designate an on-island agent (same island as the unit) HRS §521-43(f). Operators must also conspicuously display/disclose a local contact’s name, phone, and email, along with TAT registration number HRS §237D-4(b)/(c); HAR §18-237D-4-08.

If someone manages rentals for more than one owner, that is real estate brokerage activity which usually requires a Hawaiʻi real estate license HRS §467-1 (Real estate broker); §467-2(3).

OSTRA Clarification on the 30-Day vs. 90-Day Minimum Rental Requirement

Page 2 – OSTRA Clarification on 30-Day vs. 90-Day Minimum Rental Requirement

The Oahu Short-Term Rental Alliance (OSTRA) has published an official statement to address ongoing confusion regarding the minimum rental period for short-term rentals (STRs) on Oʻahu.

The document provides a timeline of ordinances, state laws, and federal court rulings that shaped the current situation:

2019: Ordinance 19-18 established a 30-day minimum rental period.
2022: Ordinance 22-7 sought to increase the minimum to 90 days.
2023: A federal court issued a permanent injunction, preventing the City from enforcing the 90-day rule retroactively and preserving the 30-day standard for pre-existing rentals.
2024: State Act 17 granted counties broader authority to regulate nonconforming uses.
2025: Bill 62 (Ordinance 25-2) was passed, but it did not change the minimum rental period.

The City’s Department of Planning and Permitting (DPP) has confirmed:

It cannot retroactively apply the 90-day minimum.
Pre-existing STRs must be treated as lawful nonconforming uses under the 30-day minimum.
The City will continue to enforce the rule that STRs are defined as rentals of less than 30 consecutive days.

Summary: While the statute reflects a 90-day minimum, the combination of court injunctions and enforcement challenges means that Honolulu continues to operate under the 30-day minimum standard.
