Are short-term vacation rentals allowed in residential neighborhoods on Oʻahu?

Generally, rentals of less than 90 days in residential areas are restricted unless specifically permitted or located in designated resort zones such as Waikīkī and Ko Olina. Registration and compliance requirements apply.

Do I need a permit for monthly (30+ day) rentals on Oʻahu?

Rentals of 30 days or more typically do not require short-term rental permits; however, owners must comply with zoning, registration, and any building or association rules that apply.

What changed in 2025 regarding Oʻahu’s rental limits?

Ordinance 25-02 (Bill 62) took effect in 2025 but did not change the minimum stay requirement. While a 90-day minimum remains in the ordinance text, a federal court injunction and practical constraints limit City enforcement, and the Department of Planning and Permitting has stated it will continue to enforce 30-day minimums.

So what is the current enforcement reality for guests and owners?

Because the 90-day rule cannot be applied retroactively, pre-existing rentals are treated as lawful nonconforming uses under the 30-day standard. In practice, the City continues to enforce short-term rentals as stays of less than 30 consecutive days.

Understanding Oahu’s Rental Limits for Short-Term and Monthly Stays

July 15, 2025

Updated August 27, 2025

Managing or staying in a vacation rental on Oʻahu requires a clear understanding of the City’s current rules on rental minimums. Over the years, ordinances, state laws, and federal court rulings have created confusion between the 30-day and 90-day minimum stay requirements. This post summarizes the most recent updates so property owners and guests know what to expect.

Timeline: Evolution of Oahu’s Short-Term Rental Laws

Infographic showing the timeline of key changes in Oahu’s short-term rental regulations from 2019 to 2025, including Bills 89 and 41, the 2023 court ruling, Act 017 (SB 2919), and CO 25-02 (Bill 62).

2019: Bill 89 (Ordinance 19-18) enacted, requiring short-term rentals outside designated resort zones to have special permits. Rentals under 30 days are severely restricted to manage community impact.
2022: Bill 41 (Ordinance 22-7) was introduced, increasing the minimum stay requirement from 30 days to 90 days for rentals outside resort zones. This significantly limited short-term rentals in residential areas.
2023: A court ruling reversed the 90-day minimum rental rule in Bill 41 back to 30 days, citing overreach. However, strict enforcement and permit requirements remain active.

2024: Act 017 (SB 2919) signed into law by Governor Josh Green, granting counties complete control over short-term rentals (STRs). Counties can now regulate the “time, place, manner, and duration” of STRs, including authority to phase out or amortize existing legal STRs. This law has implications for Waikiki condotels.
2025: CO 25-02 (Bill 62) reinstates the minimum rental duration to 90 days (up from 30 days) in residential neighborhoods. This law eliminates previous exemptions for temporary workers, displaced tenants, medical emergencies, and families in transition. Changes are documented in the revised LUO-Land Use Ordinance dated January 30, 2025. However, enforcement continues under the 30-day standard.

Summer 2025: The City and County of Honolulu (CCH) Department of Planning and Permitting is currently enforcing a 30-day limit for non-resort zoned property. This is ongoing and subject to change as CCH continues to crack down on short term rentals.

Current Enforcement Reality

According to the Department of Planning and Permitting (DPP), enforcement of short-term rentals (STRs) is limited by the federal court injunction and practical constraints:

The City can only enforce Ordinance 22-7 prospectively. It cannot apply the 90-day rule retroactively to rentals that were already operating under the 30-day minimum before the law passed.
Pre-existing STRs must be treated as nonconforming uses and can continue to operate under the 30-day minimum.
To enforce the 90-day rule, DPP would need to identify all STRs that operated prior to 2022 and determine their historic rental practices. This would require substantial resources and increase zoning appeals cases.
DPP has publicly confirmed: “The Department of Planning and Permitting will continue to enforce STRs as less than 30 consecutive days across the board.” OSTRA Statement Regarding Oahu Short-Term Rental 90 versus 30 Day Minimum.

What This Means for Owners and Guests

In summary, while Honolulu’s current ordinance sets a 90-day minimum on paper, enforcement continues to be based on the 30-day standard. This means:

Guests booking STRs can still find 30-day rental options across Oʻahu.
Property owners operating before Ordinance 22-7 may continue under the 30-day minimum.
Future changes remain possible as state and county laws evolve, so staying updated is critical.

Off-Island & Out-of-State Owner Requirement

Hawaiʻi law HRS §521-43(f) requires that all off-island or out-of-state property owners with Short-Term Vacation Rentals (STRs) and Mid-Term Rentals designate a licensed on-island agent or property manager to act on their behalf.

This requirement ensures that:

There is always a local, licensed contact available to respond quickly to guest needs, emergencies, or compliance issues.
The property remains in compliance with City & County of Honolulu regulations and state law.
Guests, neighbors, and the City can reach a responsible party on-island if concerns arise.

For owners who live on the mainland or abroad, partnering with a trusted Hawaiʻi property manager is not just a smart business decision, it’s a legal obligation. Failing to designate an on-island agent can lead to fines and enforcement actions.

Navigating Short-Term Vacation Rental Regulations on Oahu

Short-term vacation rentals (under 30 days) on Oahu are primarily regulated under the Hawaii Vacation Rental Act, designed to balance tourism and community harmony. Here’s what hosts need to know:

Resort Zones vs. Residential Areas: Rentals under 30 days are generally allowed within designated resort areas like Waikiki and Ko Olina with proper permits. Outside these zones, rentals under 30 days require special permits or are entirely prohibited.
Registration Requirements: Hosts must register with the Hawaii Department of Business, Economic Development, and Tourism (DBEDT). Registration numbers must be prominently displayed on rental listings.
Occupancy Limits: Maximum occupancy limits, based on property size, are strictly enforced for safety and community standards.
Community & HOA Rules: Always check with local homeowners’ associations or neighborhood community rules, as additional restrictions or outright bans may apply.

Understanding Monthly Rental Regulations on Oahu

Monthly rentals (30 days or more) are often subject to fewer restrictions but are still closely regulated to prevent transient activities in residential areas:

Zoning & Permitting: Monthly rentals are typically allowed in residential zones without special short-term permits. However, certain neighborhoods may have additional restrictions or require permits for rentals exceeding 30 days.
Registration & Compliance: Property owners renting for monthly stays often must register with city authorities, ensuring adherence to local safety and health standards.
Lease Duration: Hawaii law limits some residential rental agreements to no more than six months without specific licensing or special conditions.
Community Restrictions: Even monthly rentals might face neighborhood-specific rules, designed to maintain community stability and quality of life.

Key Recommendations for Hosts and Renters

Verify zoning and permit requirements through Honolulu’s Department of Planning and Permitting.
Confirm HOA rules and community guidelines prior to renting or listing a property.
Stay updated on legislation, as Oahu’s rental laws frequently evolve.

By thoroughly understanding and complying with these regulations, property owners and guests can confidently participate in Oahu’s vibrant rental market while protecting the island’s unique community fabric.
