Oahu Short-Term Rental Market Report 2026

Oahu STR 2026: the highest-ADR, most-regulated market in the US. Legal unit supply, Ko Olina and North Shore benchmarks, TAT impact, and what the deal math actually requires.

Oahu STR 2026: The Highest-ADR Market in the US Has Almost No Legal Inventory

Oahu legal short-term rental supply is measured in hundreds of units, not thousands. After Honolulu Bill 41 took effect, non-hosted STRs outside designated resort zones became illegal across the vast majority of Oahu residential land. The island receives 5 to 6 million visitors per year. The STR supply legally serving that demand, outside of hotels, is a fraction of what it was three years ago. The operators holding legal Oahu units are posting RevPAR numbers that are among the highest in the United States: $200 to $400 per night for permitted properties in premium locations. The scarcity is doing the work.

This is not a market where you browse Zillow, find a beachfront condo, and start hosting. The first question for any Oahu STR operator or prospective investor is not what is the ADR, but is this unit legally permitted to operate as a non-hosted short-term rental. If the answer is no, the revenue numbers are irrelevant because the enforcement risk eliminates the business case entirely.

The Regulation Reality: What Bill 41 Did and What It Did Not Do

Honolulu Ordinance 22-7 (Bill 41) created a framework that effectively prohibits new non-hosted STRs (meaning rentals where the host is not present on site) outside of designated resort zones. The ordinance went into effect in 2022 and has been enforced progressively through 2023, 2024, and into 2026. Fines for operating an illegal STR in Honolulu start at $1,000 per day and escalate. The city has an active enforcement mechanism that includes platform data requests, neighbor complaints, and direct inspection.

What remains legal falls into specific categories. Resort-zoned properties, primarily in Ko Olina and portions of Waikiki, retain STR rights because of their zoning designation. Legally grandfathered non-conforming use permits (NUCs) that predate the ordinance are valid but cannot be transferred with property sales in most cases, meaning the permit does not convey when a grandfathered unit sells. Hosted rentals, where the owner is present in the home, are treated differently but have their own permit requirements.

• Non-hosted STRs: illegal outside designated resort zones as of 2026
• Resort-zoned properties (Ko Olina, select Waikiki buildings): STR permitted with county registration
• Grandfathered NUC permits: valid for existing holder, generally do not transfer on sale
• Hosted rentals (owner present): separate permit category with different requirements
• Fines: $1,000 per day starting fine for unpermitted operation, escalating

The practical implication for investors is severe. A legal Oahu STR unit is one that sits in a resort zone or holds a transferable permit. The universe of such units is small. When they come to market, they trade at significant premiums to comparable non-STR units precisely because the legal STR right is a scarce, income-producing asset. Buyers should expect to pay that premium and underwrite accordingly.

Submarket ADR and RevPAR by Zone

Ko Olina Resort Area

Ko Olina on the west side of Oahu is the clearest legal STR investment zone on the island. The resort area includes hotel properties and condo-hotel buildings with resort zoning that permits non-hosted STR operation. Two-bedroom Ko Olina resort units command ADR of $400 to $600. Occupancy for well-managed units runs 72 to 85 percent. RevPAR for Ko Olina 2BRs sits in the $290 to $490 range. These are exceptional numbers by any US STR market comparison. The trade-off is acquisition cost: Ko Olina resort units that carry legal STR rights are priced at $800,000 to $2,000,000 depending on size and position, and HOA fees in resort buildings are substantial.

Waikiki (Select Condotel Buildings)

Waikiki is hotel-dense and has limited residential STR supply. Specific buildings designated as condotel (condominium-hotel hybrid structures) retain legal STR operation rights because of their original hotel zoning. These buildings include front desk operations, rental management programs, and transient-use rights embedded in their governing documents. Studio and one-bedroom condotel units in Waikiki run ADR of $180 to $320. Occupancy averages 70 to 82 percent for units in well-run rental programs. RevPAR sits at $135 to $260. The critical diligence item is confirming that a specific unit in a specific building carries transferable STR rights, not assuming that all Waikiki condos are legal STRs (most are not).

North Shore

The North Shore is one of the most recognizable coastal environments in the world, home to Pipeline, Sunset Beach, and the Vans Triple Crown of Surfing season (November through December). Legal STR inventory on the North Shore is extremely limited. Properties that do have legal operating status command ADR of $280 to $450 for two-bedrooms, with surf season (November-December) pushing rates to $400 to $600. Occupancy for legal North Shore units averages 70 to 82 percent. RevPAR sits at $200 to $370. These are some of the highest RevPAR figures in the US STR market. Supply is not growing: the regulation environment and North Shore community character make new STR permitting effectively impossible.

Kailua and the Windward Coast

Kailua is premium residential and nature-tourism territory, home to Kailua Beach and Lanikai Beach, both consistently ranked among the best beaches in the US. Legal STR supply in Kailua is constrained by the same regulatory framework as the rest of Oahu residential areas. Properties holding legal operating permits run two-bedroom ADR of $250 to $380. Occupancy averages 68 to 80 percent. RevPAR sits at $175 to $300. Kailua attracts a sophisticated leisure traveler willing to pay for the residential neighborhood experience over Waikiki hotel density.

The Transient Accommodations Tax and Net Return Reality

Hawaii state imposes the Transient Accommodations Tax (TAT) on all short-term rental operators. The TAT rate as of 2026 is 10.25 percent of gross rental revenue. On top of the TAT, Hawaii has a General Excise Tax (GET) of 4 percent (4.5 percent in Honolulu County) that applies to gross revenue including the TAT component. The combined effective tax rate on Oahu STR gross revenue is approximately 14 to 15 percent before any other expenses.

This tax burden is meaningful for net return underwriting. An Oahu 2BR generating $8,000 in monthly gross revenue faces $1,120 to $1,200 per month in TAT and GET alone. Annual gross of $96,000 carries approximately $13,500 to $14,400 in state and county taxes. Operators who do not model this correctly end up with net return projections that are materially overstated.

Oahu also has county property tax classifications that differentiate between owner-occupied, residential rental, and hotel/resort use. Legal STR properties classified as transient vacation rentals may face higher county property tax rates than residential classifications. Confirming the applicable tax classification for a specific property is part of the underwriting due diligence.

What Operators Already in the Market Are Seeing in 2026

The operators holding legal Oahu units in Ko Olina and the North Shore report that enforcement has actually improved their business by reducing illegal competition. In 2021 and 2022, platforms still had significant volumes of non-permitted listings competing for the same guests. As enforcement has progressively removed those listings, the legal operator base has seen occupancy improve and the ability to hold ADR without competing against illegally listed inventory.

North Shore operators with 2BR units are reporting annual gross revenue of $90,000 to $160,000 depending on property quality and management. Ko Olina resort units with professional management are producing $100,000 to $180,000 annually for 2BRs. These are gross figures before TAT, GET, HOA fees (which in resort buildings can run $1,500 to $3,500 per month), property management fees (typically 25 to 35 percent in Hawaii), and all other operating costs. Net operator profit on Oahu legal STRs is strong in absolute terms but requires sophisticated expense modeling to project accurately.

Oahu legal STR operators are not competing against a crowded market. They are one of a few hundred legal units serving millions of visitors. That math is as good as it gets in US STR.

Investment Strategy for Oahu in 2026

The deal thesis for Oahu STR investment is simple to state and hard to execute. You must acquire a unit with legal, transferable STR rights. Those units trade at premiums of 20 to 40 percent above comparable non-STR units. The premium is justified by the revenue capacity. The analysis must be done meticulously because the acquisition cost is high, the tax burden is significant, and the operating costs in resort buildings are substantial.

The MagicBnB Deal Analyzer is particularly well-suited to Oahu underwriting because the complexity of the inputs, conservative versus optimistic ADR assumptions, TAT and GET modeling, HOA and management fee projections, and occupancy scenarios by season, is exactly what the tool is designed to handle. Operators who have done the Oahu underwriting manually know how many variables can shift the net return picture. Getting the conservative scenario right before signing is the only responsible approach in a market where a 2BR unit costs $1,000,000 to $1,800,000.

For investors who cannot access legal resort-zone inventory or condotel buildings with transferable STR rights, Oahu is not an STR market. It is a residential real estate market. Do not buy assuming STR use and hope enforcement relaxes. The enforcement trend in 2026 is toward more enforcement, not less.

The Premium That Legal Oahu STRs Command

Legal Oahu STR units in Ko Olina and premium Waikiki condotel buildings have appreciated in market value as the legal supply pool has contracted. Buildings where every unit has clear STR rights have seen price premiums widen against comparable residential buildings. The income multiplier that legal STR rights represent on Oahu, often $40,000 to $80,000 in additional annual gross revenue compared to long-term rental of the same unit, capitalizes into acquisition price.

This creates a market where the best entry opportunities are either new-to-market legal units (rare and often off-market) or units where the seller has not fully priced the STR premium because they were not operating the unit to its potential. Operators who use the MagicBnB portfolio analytics tools to track actual RevPAR against market benchmarks are best positioned to identify when a legal Oahu unit is underperforming relative to its legal potential, which is the signal that value-add management can materially improve returns.

Frequently Asked Questions

Are short-term rentals legal in Oahu in 2026?

Non-hosted short-term rentals are legal in Oahu only in designated resort zones (primarily Ko Olina and specific Waikiki condotel buildings) or for properties with grandfathered non-conforming use permits that predate Bill 41. The vast majority of Oahu residential properties cannot legally operate as non-hosted STRs. Hosted rentals (owner present) have a separate, more permissive permit category.

What is the average Airbnb income in Oahu for legal operators?

Legal Oahu STR 2BR units in Ko Olina average $7,000 to $12,000 per month gross revenue. North Shore 2BR legal properties average $7,500 to $13,000 monthly. Kailua legal 2BRs average $6,500 to $10,000. After TAT (10.25 percent), GET (4.5 percent in Honolulu), management fees, and HOA costs, net operator profit is strong but substantially lower than gross revenue figures suggest.

What happened to Airbnb in Hawaii after the new STR laws?

Honolulu Bill 41 (Ordinance 22-7) effectively banned non-hosted STRs outside resort zones starting in 2022. Enforcement has been progressively strengthened through 2026. Platform listings of unpermitted properties have declined sharply as Airbnb and VRBO comply with Honolulu enforcement requests. Legal operators in resort zones have seen occupancy and ADR improve as illegal competition exited the market.

Is buying an STR in Ko Olina worth it in 2026?

Ko Olina resort-zone 2BR units producing $100,000 to $180,000 annually gross can justify acquisition prices of $800,000 to $1,800,000 depending on financing and operating cost structure. The math requires careful modeling: TAT plus GET takes 14 to 15 percent of gross, management fees run 25 to 35 percent, and HOA fees in resort buildings run $1,500 to $3,500 monthly. Net cap rates in the 4 to 6 percent range are achievable for well-operated units at current market prices.
