Kauaʻi vacation rental rules: what a TVR owner must know

Legal only inside a Visitor Destination Area or with a nonconforming use certificate renewed every year, with no grace period.

A vacation rental on Kauaʻi is legal in two cases only. The home sits inside a Visitor Destination Area and is registered with the county, or sits outside one with a nonconforming use certificate for a rental operating before March 7, 2008. Renewal is yearly. Miss it and the county issues a cease and desist and forfeiture notice.

The two kinds of legal rental

The county calls a short-term rental a transient vacation rental, or TVR. The county code, as amended by Ordinance 904, prohibits single-family vacation rentals in every area not designated a Visitor Destination Area (VDA). Properties on the National or State Register of Historic Places are the one exception.

Inside a VDA, a single-family vacation rental registers with the Director of Finance and follows the operating standards in the code. Outside a VDA, the Planning Department says renting a room or a home for less than 180 days "is not permitted, nor can it be applied for."

The one exception outside the VDA is a nonconforming use certificate, often called a TVNC. Ordinance 904 limited those to rentals operating lawfully before March 7, 2008, with an application deadline that passed long ago. No new ones are being created.

What every permitted rental must do

Ordinance 904 sets the same standards for VDA rentals and certificate holders:

• Name a contact available 24 hours a day, 7 days a week, and give that name and number to the adjacent neighbors and those directly across the street, the Planning Department, the police, Civil Defense, and the Kauaʻi Visitors Bureau.
• Post one outdoor sign, no larger than one square foot, with the certificate or registration number and the 24/7 phone number, numbers at least two inches tall.
• Put the certificate or registration number in all print and internet advertising, including listings with a rental service or real estate firm.
• Give guests a "For the Safety and Comfort of You and Your Neighbors" sheet, posted in the sleeping quarters.
• No interior lockouts.

The 2026 renewal form adds that the 24/7 contact must live on Kauaʻi year round, signed under penalty of perjury.

The annual renewal, step by step

The county's 2026 renewal application for rentals outside the VDA asks for:

• A $750 non-refundable fee by check or money order to "Director of Finance."
• The property's tax classification from kauaipropertytax.com.
• Last year's General Excise Tax and Transient Accommodations Tax annual returns and reconciliations, unredacted.
• Proof of a 5 lb. A:B:C fire extinguisher mounted near an exit.
• Dated photos of the sign, close up and from the street, plus the house from the road and the side.
• The evacuation route to the nearest public shelter.
• A link to each advertisement with the TVNC number highlighted.
• For homes in the tsunami evacuation zone, proof that the listing and the rental contract tell guests before booking.

Each property gets its own complete application, and incomplete packets are mailed back. The form accepts applications up to four months before the expiration date. The department's page says packets must go by certified mail, return receipt requested, at least two months before the renewal date; the front counter no longer accepts them. Filing on time is the holder's job. The Planning Commission's rules say the department will not send reminders.

What happens if you miss it

The county's own words: "There is no grace period. A Cease & Desist and Notice of Forfeiture will be issued for the failure to renew." The department notes that Ordinance 950, approved July 23, 2013, removed the option to reapply after a late filing.

Two other ways to lose a certificate come from the code. Ordinance 904 presumes that if the nonconforming use happened for fewer than 30 days in the year, it was abandoned. And the county's general nonconforming use rule, quoted in the Planning Commission's rules, says a use that stops for twelve continuous months cannot resume.

Selling a permitted rental

The certificate is tied to one structure. When the property sells, the new owner must file the current year's renewal form, without attachments or payment, within 30 days of the sale being recorded.

Unpermitted rentals and the platforms

Advertising is the evidence. Under the enforcement section amended by Ordinance 904, any advertisement offering a property as a vacation rental is prima facie evidence that one is operating there, and the owner must prove otherwise. The 2026 renewal form warns that the county "can pursue civil and/or criminal penalties." The Garden Island reported in April 2023 that penalties run up to $10,000 per day and that planning staff book undercover reservations to document violations. Check the current figure in Chapter 8 of the county code before relying on it.

The platforms are part of enforcement. In June 2020 the county signed agreements with Airbnb and Vrbo: hosts must supply a valid Tax Map Key number to list a Kauaʻi property, listings without one are removed, and Airbnb agreed to send the county a monthly report about its listings on the island. The planning director told The Garden Island in 2023 that illegal rentals had fallen from roughly 1,500 in 2017 to the low double digits.

Where to check a property

Before you buy, manage, or list a home, look it up on the county's "List of Approved Homestays & Non-Conforming TVR's by TMK," posted on the Planning Department's TVR page and updated August 26, 2026 at last check. It shows tax map key, permit number, address, status, tsunami zone, and renewal date. If a property is not on the list, the department says it has received enforcement action.

The Planning Department's zoning maps page has the county's interactive zoning map. To report an unpermitted rental, call the Planning Department at (808) 241-4050 and ask for an inspector.

Renewal paperwork is one of the five systems every Hawaiʻi business runs on: a calendar that fires before the deadline, not after. See the five systems or take the free ten-second reading.

Questions owners ask

Can I get a new permit for a house outside the VDA? No. The Planning Department states that short-term rental outside the VDA "is not permitted, nor can it be applied for." Certificates went only to rentals proven to be operating before March 7, 2008. The only way to hold one today is to buy a property that already has it and file the new-owner form within 30 days.

Do I still need state tax licenses? Yes. The renewal requires your General Excise Tax and Transient Accommodations Tax annual returns, and valid GET and TAT licenses are a condition of renewal under the code. Since October 1, 2021 the County of Kauaʻi also collects its own 3 percent transient accommodations tax on top of the state tax, filed on the same schedule.

Does the county remind me when renewal is due? No. The Planning Commission's rules say the department is not responsible for notifying holders of deadlines. Set your own reminder four months out and send the packet by certified mail with a return receipt.
