Hawaii Airbnb Rules 2026: Which Islands Still Allow Short-Term Rentals?

The question investors and property owners ask most often about Hawaii vacation rentals has a deceptively simple answer: it depends entirely on which island, which county, which zone, and in some cases which specific building you're asking about.

There is no unified Hawaii short-term rental law. The four major counties — Honolulu (Oahu), Maui, Kauai, and Hawaii (Big Island) — each have their own regulatory framework, their own permitting systems, and their own enforcement mechanisms. And across all four counties, the direction of change has been the same: tighter rules, fewer permitted units, higher penalties for non-compliance.

Here is the current state of the law, island by island, as of 2026.

Oahu: Resort Zones Only for True Vacation Rentals

Honolulu County defines a short-term rental (STR) as any transient accommodation rented for fewer than 30 consecutive days. In practice, this means that if you're listing on Airbnb for weekend stays, nightly stays, or stays under 30 days, Oahu's regulations apply.

True vacation rentals — units rented for less than 30 days — are legally permitted only in two areas:

Resort-zoned properties: Certain buildings in Waikiki, Ko Olina, and a handful of other resort corridors carry Resort Mixed-Use zoning that permits short-term rentals by right. The most legally secure categories are Category A buildings (Resort Mixed-Use with hotel operations, approximately 3,004 units in Waikiki) and Category B buildings (Resort Mixed-Use without hotel operations, approximately 1,182 units). These properties can operate on Airbnb legally.

Properties with Nonconforming Use Certificates (NUCs): A narrow category of apartment-zoned buildings in and around Waikiki hold NUCs — permits issued prior to October 1986 that grandfather their STR operations. NUCs must be renewed annually between September 1 and October 15. If a seller lets an NUC lapse before the sale, or if a buyer misses the renewal window after closing, the certificate is permanently revoked. These units are rare, expensive, and carry compliance risk that requires active management.

Outside of resort zones and NUC properties, the operative minimum stay for Oahu residential properties is 30 days. This creates a medium-term rental market — units rented for 30 to 180 days — that serves a different tenant base: traveling nurses, military personnel on temporary duty orders, corporate relocations. This market is legal, meaningful in volume, and significantly less regulated than vacation rental operations.

Proposed legislation (Bill 62 in 2025) attempted to extend the minimum stay in residential areas from 30 to 90 days, similar to the 2022 Ordinance 22-7 that was blocked by federal litigation. The Department of Planning and Permitting continues to enforce the 30-day standard while the legal landscape evolves. Investors should monitor this area for further legislative attempts in the 2026 and 2027 sessions.

Maui: The Minatoya Phase-Out Changes Everything

Maui's short-term rental landscape shifted fundamentally in December 2025 when Mayor Bissen signed Ordinance 5909 (Bill 9) into law.

Prior to Bill 9, approximately 6,000 to 7,000 apartment-zoned condominiums operated legally as vacation rentals under the "Minatoya List" — a 2001 legal opinion recognizing their grandfathered status. Properties like Kamaole Sands, Papakea, and Maui Vista generated vacation rental income despite their underlying A-1 and A-2 apartment zoning.

Bill 9 eliminates this protection on a staggered timeline:

• West Maui (Ka'anapali, Napili/Kahana, Lahaina): STR operations must cease by December 31, 2028
• South Maui (Kihei, Wailea, Makena) and all other affected districts: STR operations must cease by December 31, 2030

After those dates, former Minatoya-listed units cannot be legally rented for short-term vacation stays. They transition to long-term rental supply or eventual sale.

What remains legal on Maui for Airbnb-style operations: properties with genuine Hotel zoning (H-1, H-2), which have their STR rights independently from the apartment-district phase-out. These include hotel-adjacent condominiums, timeshares, and hotel-zoned developments in areas like Wailea and Ka'anapali. Licensed Bed & Breakfasts (owner-occupied with guest rooms) also remain permitted.

The practical implication: if you're evaluating a Maui property for Airbnb operations, your first question must be whether it carries Hotel zoning or relies on Minatoya grandfathering. If it's the latter, you're acquiring a time-limited STR right that expires in 2028 or 2030.

Big Island: Primary Residency Requirement for Unhosted Rentals

Hawaii County operates the most granular regulatory framework of the four. Under Ordinance 25-50 (Bill 47), signed June 2025 and effective July 2026, all rentals under 180 days — hosted or unhosted — must register with the county as Transient Accommodation Rentals (TARs) and obtain a county registration number.

Registration requires paying an initial fee ($250 for hosted rentals where the owner lives on the property; $500 for unhosted rentals) and demonstrating compliance with safety codes, GET and TAT tax payment records, and zoning requirements.

The critical restriction for out-of-state investors: since January 1, 2025, only individuals whose primary residence is in Hawaii County can operate unhosted TARs outside of designated Visitor Destination Areas (VDAs). If you live in California and want to buy a vacation rental on the Big Island and rent it out while you're not there, you can only do so legally if the property is in a VDA. Outside VDA boundaries, unhosted operation requires Hawaii County primary residency.

Visitor Destination Areas on the Big Island are primarily located along the Kona and Kohala Coast resort corridor and in certain Hilo commercial zones. If the property you're evaluating is outside those boundaries — in a residential neighborhood, rural area, or agricultural zone — unhosted operation by a mainland-based investor is not legally available under current rules.

The enforcement mechanism is notable: booking platforms like Airbnb and VRBO must register with the county ($1,000 annual fee) and submit monthly reports identifying active listings by Tax Map Key (TMK) and county registration number. Platforms must remove non-compliant listings within 10 days or face $10,000 daily fines. This makes underground operation on major platforms effectively impossible.

Kauai: Visitor Destination Areas Only

Kauai County enforces strict geographic limitations. Short-term vacation rentals are permitted only in established Visitor Destination Areas (VDAs), which are primarily located in the resort corridors of Poipu, Princeville, Hanalei, and Waimea.

Outside of VDA boundaries — in residential neighborhoods, rural areas, or agricultural zones — STR operations are not permitted. Kauai's enforcement has historically been more active than some other counties, and the penalty structure for non-compliant operators is meaningful.

For investors targeting Kauai, the investable STR inventory is concentrated in VDA-zoned buildings, which command premiums reflecting their regulatory protection. The county does not issue new VDA designations frequently, making existing permitted VDA inventory relatively constrained.

The Tax Reality: Why Rules Matter Beyond Compliance

For investors who are weighing whether to operate legally versus quietly ignoring the permit requirements, the risk calculus has shifted dramatically.

Booking platforms now supply county revenue departments with operator data through platform-level compliance mechanisms. The Big Island's monthly reporting requirement is replicated in various forms across all four counties. The era of listing an unregistered unit on Airbnb and assuming no one is tracking it is functionally over in Hawaii.

The legal operating costs are substantial: the combined state TAT (11%), county TAT (3%), and GET (4.5%) stack to 18.5% of gross rental revenue for permitted STR operations. A property generating $60,000 per year in vacation rental income owes approximately $11,100 in gross receipts taxes. This is the price of legal operation — it must be modeled accurately.

Non-legal operation carries a different set of costs: citations, back tax assessments with 25% monthly penalties (capped at 25% of owed amount) plus 20% payment penalties plus accruing interest, potential loss of the county registration eligibility, and in some cases criminal referrals for egregious or repeat violations.

What This Means for Investors

The practical effect of Hawaii's evolving STR regulations is a bifurcation of the investment market:

Legally protected STR assets — Resort Mixed-Use properties on Oahu, Hotel-zoned developments on Maui, VDA-positioned units on Kauai and the Big Island — are concentrating investor demand and commanding premiums as the legal supply of STR-eligible properties contracts.

Formerly STR-viable assets — Maui Minatoya-listed condos, residential-zone properties on Oahu, out-of-VDA properties on Kauai and the Big Island — are being repriced based on their long-term rental economics rather than their vacation rental potential.

Long-term rental properties — The majority of Hawaii's residential stock — generate compressed yields but benefit from structural housing demand, low vacancy, and county tax incentives for 12-month leases (particularly Maui's Long-Term Rental classification at dramatically lower property tax rates).

Investors who enter Hawaii's market in 2026 with a clear understanding of which category their target property falls into can make rational, fully-informed decisions. Those who assume any Hawaii property with ocean views can generate vacation rental income are operating with a model that has been systematically dismantled by the county councils over the past three years.
