Understanding Hawaiʻi County vacation rental laws has never been as simple as knowing whether a rental is shorter or longer than 30 days. On the Big Island of Hawaiʻi, including Kona and the Kohala Coast, County zoning, State Land Use classifications, vacation-rental approvals, registration requirements, taxes, and private community restrictions can all affect how a property may be used.
Even for those of us working in Hawaiʻi real estate every day, it has been confusing at times.
Thirty-day rentals. One-hundred-eighty-day rentals. STVRs. TVRs. Hosted rentals. Unhosted rentals. B&Bs. Nonconforming Use Certificates.
Confused already?
The easiest way to understand today's system is to look at how we got here.
Key Takeaways
Hawaiʻi County's modern vacation-rental framework developed in stages, beginning with the 2018 regulation of short-term vacation rentals and expanding with the 2026 TVR registration system.
The familiar “under 30 days is vacation rental, over 30 days is long term” explanation no longer accurately describes the County's broader registration framework.
A legal unhosted STVR can operate because it is in an area where the use is permitted or because it has an existing legal approval such as a Nonconforming Use Certificate, or NUC.
Existing STVRs, NUCs, and B&Bs with valid permits before September 1, 2026 are deemed registered under the new system.
The broader TVR registration framework covers hosted and unhosted transient rentals of fewer than 180 consecutive days.
Buyers should verify the individual property's registration and the legal basis for its transient-rental use rather than relying simply on what neighboring properties are doing.
The Short Version: 2018 → 2024 → 2026
2018: Bill 108
Hawaiʻi County created its modern Short-Term Vacation Rental framework, primarily regulating unhosted rentals of 30 consecutive days or less.
The law established where new STVRs could operate and created a pathway for certain existing STVRs outside permitted zoning districts to continue operating through a Nonconforming Use Certificate, commonly called an NUC.
2024: Rosehill
The Hawaiʻi Supreme Court ruled that farm dwellings in the State Agricultural District cannot be used as short-term vacation rentals.
That decision became particularly important on the Big Island, where agricultural property represents a substantial part of our real estate landscape.
2026: New TVR Registration
Hawaiʻi County launched a much broader Transient Vacation Rental registration system covering 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.
Next: Bill 147
The County is also considering broader changes to the rules governing where and how transient rentals can operate.
Now let's unpack it.
The 30-Day Rule Was Never the Whole Story
For years, I regularly heard people in Hawaiʻi real estate say:
Less than 30 days = vacation rental.
More than 30 days = long-term rental.
I never felt comfortable explaining it to clients that way. Part of the confusion came from State and County rules using different time periods for different purposes.
Hawaiʻi County's older STVR zoning framework focused on rentals of 30 consecutive days or less. Other regulations, including transient-accommodation tax rules, used broader definitions. So a 60-day or 90-day rental might not have fallen within the County's old 30-day STVR definition, but simply calling it a “long-term rental” could still be misleading. Our team has always tried to make this distinction clear.
Today, Hawaiʻi County's TVR registration framework covers accommodations rented to transients for fewer than 180 consecutive days, whether hosted or unhosted.
For practical purposes, I would no longer casually describe a 31-day rental as “long term.”
That removes one significant gray area.
Bill 108 Established the Modern STVR System
The modern County STVR system really began taking shape in 2018. Bill 108, which became Ordinance 2018-114, focused primarily on unhosted short-term vacation rentals.
The ordinance defined where STVR use would be allowed and established operating standards. It also created an avenue for qualifying existing vacation rentals outside permitted zoning districts to obtain a Nonconforming Use Certificate, or NUC, allowing continued operation. That history still matters today.
A legal STVR does not necessarily have to be located in a zoning district where a brand-new STVR could be established. An existing property may operate legally because it holds a valid NUC.
That is why one property can legally operate as an STVR while another nearby property may not have the same right. This is also why I never recommend determining vacation-rental eligibility simply by looking at what the neighbors are doing.
NUC Properties Are Legitimate STVRs
This point deserves to be clear.
An NUC is not an indication that an STVR is somehow less legitimate than one located within a normally permitted zoning district. The NUC was specifically created to allow qualifying existing STVRs to continue operating outside the zoning districts where new STVRs would otherwise be allowed.
For real estate purposes, there are therefore different legal paths to STVR operation. A property might qualify because of its zoning. Another might qualify because it has an existing NUC.
What matters to a buyer is understanding which legal basis applies to that individual property.
Hosted Rentals Followed a Different Path
Hosted rentals historically followed a different regulatory path. The basic distinction sounds easy:
Hosted: Someone resides on the property while guests are staying there.
Unhosted: The rental operates without the host residing there.
In practice, hosted rentals, traditional B&Bs, and unhosted STVRs were treated differently under the County's earlier framework. And that contributed to much of the confusion.
I am not a fan of unnecessary taxes or regulations simply for the sake of regulation. But if taxes are legally due, people operating the same type of business should generally be expected to pay them. The same principle applies to operating requirements.
The playing field should be level.
The new TVR registration system brings hosted and unhosted transient rentals into a broader County registration framework.
Rosehill Changed the Agricultural Land Discussion
Agricultural property adds another layer.
In the 2024 Rosehill v. State Land Use Commission decision, the Hawaiʻi Supreme Court addressed whether farm dwellings in the State Agricultural District could be used as short-term vacation rentals.
The Court concluded that they cannot.
This is particularly relevant on the Big Island, where agricultural property represents a substantial portion of our real estate landscape.
There is an important distinction:
County zoning and State Land Use classification are not necessarily the same thing.
Simply seeing “Agricultural” associated with a property does not give a buyer enough information to understand its vacation-rental status. You need to investigate the actual property, including any existing permits or nonconforming rights.
The 2026 TVR Registration System
On September 7, 2026, Hawaiʻi County launched its new Transient Vacation Rental registration platform.
It applies to rooms, homes, condos, and similar accommodations rented to transients for fewer than 180 consecutive days, including both hosted and unhosted rentals.
Existing TVRs with valid STVR, NUC, or B&B permits before September 1, 2026 are deemed registered and are to receive further instructions from the County.
The ordinance also provides that certain TVRs operating under qualifying use permits or State special permits are deemed registered.
This is a significant shift from the older framework. The County now has a centralized system for identifying transient-rental operations across Hawaiʻi Island. I see value in that. Clear rules are easier to follow. Clear records are easier to enforce.
STVR Registration and Legal Eligibility Work Together
This is an important clarification for buyers and property owners.
For an unhosted STVR, there must be a legitimate basis for the property to operate. That may be because the property is located where STVR use is permitted under County zoning. Or it may be because the property holds a valid NUC or another qualifying approval allowing the use to continue.
The new registration system does not erase those distinctions. Instead, existing permitted STVRs and NUC properties are incorporated into the broader TVR registration system.
For a buyer, the practical question is therefore not simply:
“Is this property zoned for vacation rentals?”
The better approach is to confirm the property's current County registration and understand why the property is legally entitled to operate as an STVR.
For some properties, zoning provides the answer. For others, the answer may be an NUC. That distinction is particularly important on the Big Island.
TVR and STVR Should Not Be Used Interchangeably
Another source of confusion is terminology.
The new TVR registration category is broader than the older STVR category.
An STVR historically referred primarily to an unhosted rental for 30 consecutive days or less under the County's zoning framework. The newer TVR registration system covers transient rentals of fewer than 180 consecutive days and includes both hosted and unhosted operations.
So while an existing legal STVR now falls within the TVR registration system, not every TVR should automatically be described as an STVR.
That distinction will become increasingly important as the regulations evolve.
Bill 147 Represents the Next Chapter
The story is not finished.
Bill 147 addresses a broader regulatory framework for transient vacation rentals, including matters involving B&B uses, permitted locations, permitting, enforcement, and operating standards.
This is separate from the registration system that is already operating.
I would not make a purchase decision today based on an assumption about what the final version of Bill 147 will say since proposed legislation can change.
We need to separate today's rules from tomorrow's proposal.
Big Island Vacation Rental Due Diligence
If vacation-rental income matters to your Big Island purchase, do not simply ask: “Can I vacation rent this property?”
Instead, I would verify:
Current County TVR registration
Whether the property operates as an STVR, hosted rental, B&B, or another type of TVR
County zoning
Any valid NUC, use permit, special permit, or other existing approval
State Land Use classification
Intended rental duration
Applicable taxes
Condo, HOA, resort, or community restrictions
That sounds like a lot, and it is.
But it is much easier to investigate these questions before buying than to discover a problem afterward. In Kona and along the Kohala Coast, two properties that look very similar can have different rental rights because of zoning, existing approvals, NUC status, or private community rules.
Common Misconceptions
A 31-Day Rental Is Automatically Long-Term
Not anymore, at least not as a general description. The County's TVR registration system reaches transient rentals of fewer than 180 consecutive days.
An STVR Must Be in STVR-Permitted Zoning
Not necessarily. Qualifying pre-existing STVRs outside normally permitted zoning districts were able to obtain NUCs allowing them to continue operating legally.
An NUC Property Is an Illegal or Questionable Vacation Rental
No. A valid NUC is the legal mechanism created by Hawaiʻi County for qualifying existing STVRs to continue operating outside permitted zoning districts.
A Neighbor's Vacation Rental Establishes My Property's Rights
No. The neighboring property may have different zoning, an NUC, another permit, or a different regulatory history.
Each property needs to be checked individually.
TVR and STVR Mean Exactly the Same Thing
No. The current TVR registration system is broader. It includes hosted and unhosted transient rentals of fewer than 180 consecutive days, while the older STVR framework addressed a narrower category of short-term rental use.
Greater Clarity, but Property Details Still Matter
After years of dealing with these rules, I think we are gradually moving toward greater clarity. The new registration system should make it easier to identify transient rental operations and to understand their status.
But Big Island real estate is still property-specific.
Unlike many mainland markets, Hawaiʻi can involve County zoning, the State Land Use system, existing nonconforming rights, permits, tax rules, and private community restrictions simultaneously.
Our team's role is not simply to give a quick “yes” or “no.” It is to help identify the right questions and verify what applies to the individual property.
Every property is different.

Frequently Asked Questions
What is considered a transient vacation rental in Hawaiʻi County?
Under Hawaiʻi County's 2026 registration framework, rooms, homes, condos, and similar accommodations rented to transients for fewer than 180 consecutive days generally fall within the TVR registration system, whether hosted or unhosted.
Is a 31-day rental considered long-term on the Big Island?
Not necessarily. The current County TVR registration framework covers transient rentals of fewer than 180 consecutive days, so a 31-day rental should not automatically be described as long term for every regulatory purpose.
Does an STVR have to be located in a zoning district where new STVRs are permitted?
No. A qualifying pre-existing STVR may legally operate outside normally permitted zoning districts if it holds a valid Nonconforming Use Certificate, or NUC.
What is a Nonconforming Use Certificate?
An NUC is the County mechanism that allowed qualifying existing STVRs to continue operating outside zoning districts where new STVRs otherwise would not be permitted.
Are NUC vacation rentals legal STVRs?
Yes. A valid NUC provides the legal basis for a qualifying nonconforming STVR to continue operating under Hawaiʻi County's framework.
Are existing STVR and NUC properties registered under the new system?
The County states that existing TVRs with valid STVR, NUC, or B&B permits before September 1, 2026 are deemed registered and will receive further instructions.
Is every TVR the same as an STVR?
No. TVR is now the broader registration category. It includes hosted and unhosted transient rentals of fewer than 180 consecutive days. STVR refers to the narrower short-term rental category established under the earlier County zoning framework.
Are County agricultural zoning and State Agricultural District classifications the same?
No. Hawaiʻi County zoning and the State Land Use system are separate regulatory layers. Both may need to be examined when evaluating a property.
Can two homes in the same neighborhood have different vacation-rental rights?
Yes. One property could qualify through permitted zoning while another may hold an NUC or another approval. A nearby property therefore does not establish the legal status of another parcel.
What should buyers verify before relying on Big Island vacation-rental income?
Buyers should verify current County registration, the legal basis for the property's rental use, County zoning, any NUC or other approval, State Land Use classification, rental duration, applicable taxes, and private condo, HOA, resort, or community restrictions.
