Hawaiʻi County Offers STR Hosts a 4-Month Window to Register or Face Fines

Short-term rental owners in Hawaiʻi County who still haven't registered their properties just got a lifeline, but it comes with a hard deadline. A county council committee has forwarded a measure that would waive violation fees from Sept. 1 to Dec. 31, giving unregistered hosts a 4-month grace period to get on the books before enforcement begins in earnest. Miss that window, and the fees start stacking up.

What Just Happened

The Hawaiʻi County Council's Policy Committee on Planning, Land Use and Economic Development advanced a bill with a favorable recommendation. Council member Heather Kimball introduced the bill specifically to pause violation fees while the county finishes building its registration platform. The underlying registration requirement is not new: it was locked in when the council passed Bill 47, Ordinance 25-50 in July 2025, which overhauled vacation rental rules across the board. Owners were supposed to be registered by December 2025. Many aren't, and the county knows it.

The holdup isn't entirely on hosts. The county has been developing its registration system through Deckard Technologies, a platform used by more than 500 jurisdictions to manage short-term and long-term rental compliance. That build has taken time, and Kimball's bill is a direct acknowledgment that penalizing hosts before a convenient registration path exists would be unfair.

What Ordinance 25-50 Actually Changed

Bill 47 wasn't a minor tweak. The ordinance clarified definitions of what counts as a short-term rental, added licensing requirements for hosted stays, tightened eligibility rules for unhosted rentals, and introduced tougher enforcement measures. It also created new platform accountability rules targeting listing sites like Airbnb and VRBO. In short, the county drew a much clearer line around who needs to register and what happens if they don't.

Kimball put it plainly at the committee meeting: "It is well-documented on tax assessments and on the county website that whenever you rent your property for less than 180 days, it is a short-term rental." The rule applies broadly, and the county is not looking to grandfather anyone out of it.

The Stakes for Hosts Right Now

If the bill passes the full council, the grace period runs from September 1 through December 31. During that window, violation fees are waived. After December 31, they are not. The cost of ignoring this deadline is significant, making early action the only sensible path.

Registration is not automatic. Planning Director Jeffrey Darrow outlined the process at the committee meeting: applicants must meet all requirements before they can be registered, including submitting a site drawing. Hosts should expect a checklist-style application, not a simple online form, so starting early matters.

Kimball also left the door open to extending the grace period if hosts need more time, saying she is "certainly open to the conversation" if a longer window proves necessary. But that is not guaranteed, and waiting to find out is a risk.

What Hosts Should Do Now

• Confirm whether your property qualifies as a short-term rental under the county's definition: any rental of less than 180 days.
• Determine whether your stay is hosted or unhosted, since Ordinance 25-50 added separate licensing requirements for hosted stays.
• Watch for the county's Deckard Technologies registration platform to go live and submit your application as soon as it does.
• Gather required materials, including a site drawing, before the platform opens so you are not scrambling at the deadline.
• Track the bill through the full council vote to confirm the grace period is officially in effect.

The county's message is clear: it wants compliance, not confrontation. The grace period is the carrot. The fines waiting on the other side of December 31 are the stick.
