Kauai County short-term rental laws (2026)
On Kauai, one line decides everything: the Visitor Destination Area. Outside it, the county says a rental of less than 180 days is not permitted and cannot be applied for. Owners who hold an older certificate lose it for good if they miss one renewal.[1]

Kauai short-term rental rules
Kauai County prohibits single-family vacation rentals everywhere outside its Visitor Destination Areas. The only rentals allowed outside hold a Nonconforming Use Certificate, for use that began before March 7, 2008. The county stopped taking applications in 2011. Holders renew every year, and the 2026 form sets the fee at $750. Inside a Visitor Destination Area, a new single-family vacation rental registers with the Director of Finance before any use. Every rental names a contact available around the clock, posts one small sign and puts its number in every ad. Running a vacation rental without a certificate can cost up to $10,000 per day.[3]

Stays of 180 days or more in Kauai County
- Kauai County allows short-term rentals in certain zones only. A stay of 180 consecutive days or more is not a short-term rental under its rules.[1]
- The county states this line for homes outside the Visitor Destination Area.
- At that length, a guest can gain tenant rights, and lodging tax and insurance work differently.
