Hawaiʻi County's new vacation rental registration system is now in effect across the Big Island, including Kona and the Kohala Coast, starting September 2026. The change is straightforward at its core: transient rentals of fewer than 180 consecutive days now fall under a broader County registration system, whether hosted or unhosted. For property owners, buyers, and sellers, the real question is what to do next.
Key Takeaways
Hawaiʻi County launched its new Transient Vacation Rental, or TVR, registration system on September 7, 2026.
The system covers hosted and unhosted transient rentals of fewer than 180 consecutive days.
Existing TVRs with valid STVR, NUC, or B&B permits before September 1, 2026 are deemed registered.
Owners should confirm and organize their registration records. Sellers should document a property's rental status before marketing it. Buyers should verify that status before relying on vacation-rental income.
The new system makes the old assumption that “anything over 30 days is long term” much less useful.
Hawaiʻi County Vacation Rental Registration in Practical Terms
For years, many people in Hawaiʻi real estate used 30 days as the easy dividing line between vacation rentals and long-term rentals.
That was always a little too simple.
Under the new County framework, the important registration threshold is fewer than 180 consecutive days. A room, home, condo, or similar accommodation rented to transients within that period generally falls under the TVR registration requirement, whether the rental is hosted or unhosted.
So a 31-day, 60-day, or 90-day rental should no longer casually be treated as outside the vacation-rental discussion.
The broader history of how Hawaiʻi County arrived here is covered in my separate article on Big Island vacation-rental laws. For this update, the more useful issue is what owners, sellers, and buyers should do now.
Existing Vacation-Rental Owners
If you already operate a legal vacation rental, the first step is relatively simple: confirm your status and keep your documentation organized.
The County states that existing TVRs with valid STVR, Nonconforming Use Certificate (NUC), or B&B permits before September 1, 2026 are deemed registered and will receive further instructions.
That means an established legal operator is not starting over.
I would keep the following together:
Current TVR registration information
Existing STVR, NUC, or B&B documentation
County correspondence
Tax records
Any applicable condo, HOA, or resort rental rules
For an unhosted STVR, its legal operating basis may come from permitted zoning or from an existing approval such as an NUC. The NUC is important because it allowed qualifying pre-existing STVRs outside normally permitted zoning districts to continue operating legally.
The practical point is simple: know what approval your property operates under and keep the records.
Buyers Should Verify Before Relying on Rental Income
For buyers, I think the new system actually makes one part of due diligence clearer.
If a Big Island property is marketed as a vacation rental, I would want to confirm the County registration and understand the basis for its legal rental status.
Rental history tells you how the property has performed financially. Registration and existing approvals tell you something different: how the property is recognized within the County's regulatory system.
Before relying on vacation-rental income, I would verify:
Current TVR registration
Existing STVR, NUC, B&B, or other applicable approval
County zoning and any relevant State Land Use issues
Condo, HOA, resort, or community rental restrictions
Intended rental duration
Applicable tax requirements
This matters particularly in Kona and along the Kohala Coast, where two nearby properties can look very similar but have different rental histories or approvals.
Do not assume the neighbor's rental rights apply to the property you are buying.
Sellers Should Make the Rental Status Easy to Understand
For sellers, documentation is becoming more important.
If vacation-rental use adds value to the property, I would want that status clearly documented before the property goes on the market. A buyer should not have to piece the story together from old advertisements, tax returns, Airbnb screenshots, and verbal explanations. If the property has a valid STVR, NUC, B&B permit, or TVR registration, have that information ready.
This does not mean guaranteeing what a future owner can do. It means presenting the property's current regulatory status accurately and giving the buyer the information needed for independent verification.
In my experience, clarity creates confidence, particularly when rental income is an important part of the purchase.
The New System Also Matters to 31-to-179-Day Rentals
This may be the biggest practical adjustment for some property owners.
If your strategy has been to avoid short-term vacation-rental rules by renting only for 31, 60, or 90 days, the new registration framework deserves your attention.
The County's registration definition now extends to transient rentals of fewer than 180 consecutive days.
That does not mean every type of TVR is identical. The new TVR category is broader than the older STVR category. It includes hosted and unhosted transient rentals, while the older STVR framework dealt with a narrower form of short-term rental use.
That terminology matters when reviewing a property's status.
Registration Should Make the Market More Transparent
I have mixed feelings about regulation. I do not believe adding more rules automatically makes a system better, and I am certainly not a fan of unnecessarily high taxes. But I do believe people operating the same type of business should generally be expected to follow the same requirements.
The County says the registration system is intended to create current information about transient-rental operations and improve enforcement of requirements such as parking and response times for neighborhood complaints.
From a real estate standpoint, better records should also make it easier for buyers, sellers, and owners to understand what they are dealing with.
The Practical Bottom Line
For property owners, confirm your registration status and organize your existing approvals.
For sellers, document the property's current rental status before marketing vacation-rental use or income.
For buyers, verify the registration and understand the legal basis for the property's rental operation before including vacation-rental income in your purchase decision.
And if your strategy involves rentals between 30 and 179 days, do not assume the old 30-day rule keeps you outside the new system.
There are still details to work through, and Hawaiʻi County's broader vacation-rental regulations continue to evolve. But for now, the immediate message is fairly simple:
Know your property's status. Keep the documentation. Verify before you buy.
