The rules around vacation rentals in Hawaiʻi are changing faster than most travelers realize. Maui County signed a law phasing out thousands of short-term rentals in apartment-zoned areas. The Big Island’s new registration and enforcement system kicks in July 1, 2026. And across the state, counties are tightening the screws on unregulated listings.

If you’re booking a vacation rental for summer 2026, you need to verify your accommodation is legal before you hand over a deposit. An illegal listing can vanish overnight — and your money with it. Here’s what’s happening on each island and how to protect yourself.

Maui Mayor Richard Bissen signed Bill 9 into law in late 2025, after the Maui County Council passed it in a 5-3 vote. The bill phases out short-term vacation rentals in apartment-zoned areas across the island — roughly 7,000 units. Honolulu Civil Beat

The timeline: West Maui units must cease operating by January 1, 2029. The rest of the island’s apartment-zoned rentals follow by 2031. No automatic removals happen in 2026 or 2027, but owners are already pulling units off the market in anticipation. About 60% of affected units are in South Maui, with 36% in West Maui — the areas most popular with repeat visitors and families.

The University of Hawaiʻi Economic Research Organization (UHERO) projects a $900 million annual decline in visitor spending once the phase-out is complete, along with 1,900 lost jobs and a $60 million drop in property tax revenue. Maui condo prices have already dropped 25.6%.

Two lawsuits filed in December 2025 challenge the law as an unconstitutional taking of property rights. No rulings as of March 2026. And a February 2026 attempt to save roughly 4,500 units through new hotel zoning districts was rejected 5-1 by the Maui Planning Commission.

Your summer 2026 Maui trip is not in jeopardy — yet. Most vacation rentals continue operating under existing rules, and more than 12,500 legal vacation rentals remain active, including resort-zoned condos and hotels. Beat of Hawaii

But the supply is shrinking. Some owners are converting units to long-term rentals ahead of the deadline. Others are selling. If you’ve been returning to the same condo year after year, confirm it’s still available and legally operating before booking. Hotels gain pricing power as rental inventory drops — expect rates to creep up, especially in Wailea and Kāʻanapali.

Hawaiʻi County’s Bill 47 (Ordinance 25-50) takes effect July 1, 2026. Every short-term vacation rental on the Big Island — hosted or unhosted, stays of 180 days or fewer — must register with the county. Hawaiʻi Public Radio

Registration fees: $250 for hosted rentals, $500 for unhosted. Annual renewal required. Booking platforms like Airbnb and VRBO must also register with the county ($1,000 fee) and submit monthly reports of all listings. Hawaiʻi Tribune-Herald

Fines for operating without registration after July 1 range from $1,000 to $10,000 per violation — and they stack. One property owner calculated potential exposure of $300,000 per month in fines during a three-month appeals process. KE Team Hawaii

The catch: the county hasn’t built the registration portal yet. Owners can’t register until the system is live, but penalties are already written into law. If you’re booking a Big Island rental for late summer, ask your host directly whether they’ve completed registration.

Oʻahu has restricted short-term rentals outside resort zones since 1989. Bill 89 (2019) created a registration system and capped non-resort-zone permits. Enforcement has been inconsistent, but the city has been issuing fines and cease-and-desist orders more aggressively since 2024. If a listing doesn’t display a valid registration number, it’s probably illegal. Minut — Hawaii STR Laws

Kauaʻi requires a Non-Conforming Use Certificate (NCUC) for vacation rentals in most areas, and the county stopped issuing new ones years ago. The existing pool of legal rentals is fixed and shrinking. Illegal operators face fines up to $10,000 per day.

Neither island has new legislation pending, but the statewide trend is clear: fewer legal rentals, higher fines, and platforms under increasing pressure to delist unregistered properties.

Every legal vacation rental in Hawaiʻi must have a state General Excise Tax (GET) license and a Transient Accommodations Tax (TAT) registration. You can verify both through the Hawaiʻi Tax Online system. Hawaii’s Best Travel

Beyond state taxes, check county-specific permits. On Oʻahu, look for a registration number (NUC or TVU). On the Big Island after July 1, ask for the county registration confirmation. On Maui, confirm the unit isn’t in an apartment-zoned area subject to the phase-out. On Kauaʻi, ask for the NCUC number.

Red flags: listings that don’t show any permit or tax numbers, hosts who dodge questions about legal status, and prices that seem too low for the area. If a deal looks too good to be true, the unit may not exist legally by the time you arrive.

Hawaiʻi’s housing crisis predates the 2023 Maui wildfires, but the fires made it impossible to ignore. Thousands of Lāhainā residents lost their homes. Rents across the state sit among the highest in the nation. Local workers in tourism, education, and healthcare can’t afford to live where they work.

The argument for phasing out vacation rentals is straightforward: converting short-term units back to long-term housing increases supply for residents. The counterargument is that many of these condos — small, vacation-oriented, with high HOA fees — won’t become affordable housing regardless. Cities like Barcelona and New York have tried similar bans without meaningful rent reductions.

For visitors, the practical impact is this: fewer rental options, higher hotel rates, and a booking process that now requires due diligence. The era of finding a cheap condo on Airbnb and winging it is ending.

Book early. Verified legal rentals are selling out faster as supply tightens. Hotels and resort-zoned condos are unaffected by any of these laws and remain a reliable option on every island.

If you’re renting a car alongside your accommodation, lock in rates now — summer demand spikes by May. Discount Hawaii Car Rental compares prices across agencies and consistently finds the lowest rates for Hawaiʻi.

Keep receipts and confirmation numbers for everything. If a rental gets delisted between booking and arrival, having documentation speeds up the refund process through your booking platform or travel insurance.
