Kauai County, HI Short-Term Rentals: Short-Term Rental Parking Rules (2026)

Sec. 8-18.2 of the Kaua'i County Code layers homestay-specific development standards onto the base residential standards in Secs. 8-4.5 through 8-4.8. The parking rule in Sec. 8-18.2(a) is per-bedroom: each bedroom used for homestay purposes requires one additional paved and designated off-street parking stall, separate from the parking the house needed for ordinary residential occupancy. A property offering the maximum three guest rooms permitted under Sec. 8-18.1(a)(2) therefore needs three extra paved stalls dedicated to the homestay use, on top of standard household parking.

The same Section 8-18.2 list layers on other standards that interact with site planning around the parking area: at least a septic system approved by the State Department of Health servicing the homestay structure, a 24-hour contact requirement for the homeowner-exemption holder, a required one-square-foot outdoor sign with numerals no smaller than two inches showing the zoning permit number, and a site and floor plan that must be filed with the homestay application so the Planning Department can confirm the paved stalls actually exist before a permit issues. Because the parking stalls must be paved and designated, a grass or gravel parking area, or an undesignated shared driveway, does not satisfy Sec. 8-18.2(a) even if physical space for a vehicle exists.
