Summary
Kaua'i County Code § 8-1.5 defines a lawful "home business" as one carried on solely by a dwelling's own occupants, and it draws a hard line at customer traffic: any activity that involves, encourages, or depends upon frequent visits by the public, or any shop or clinic of any type, is disqualified from home business status entirely on Kaua'i (Kaua'i County).
"Home business"means any use customarily conducted entirely within a dwelling and carried on solely by the inhabitants thereof, in connection with which there are: no display from the outside of the building; no mechanical equipment used except as is normally used for domestic or household purposes; and no selling of any commodity on the premises; which use is clearly incidental and secondary to the use of the dwelling for dwelling purposes and does not change the character thereof. The office, studio, or occupational room of an architect, artist, engineer, lawyer or other similar professional person; a family child care home; business conducted entirely by phone or by mail (not involving frequent bulk shipments); and an office for "homework" of a person in business elsewhere; all shall be permitted as home businesses except that no activity involving, encouraging, or depending upon frequent visits by the public and no shop or clinic of any type shall be deemed to be a home business.
Full Breakdown
The Comprehensive Zoning Ordinance's home business definition at § 8-1.5 permits professional-type uses run entirely by a dwelling's own residents, such as the office of an architect, artist, engineer, or lawyer; a family child care home; phone or mail-order business not involving frequent bulk shipments; and remote "homework" for an employer elsewhere. All of these are allowed home businesses on Kaua'i (Kaua'i County) so long as the use stays incidental and secondary to the dwelling's residential character. The same sentence, however, carves out a hard exception: no activity that involves, encourages, or depends upon frequent visits by the public, and no shop or clinic of any type, qualifies as a home business at all.
That means a resident cannot rely on the home business classification to receive walk-in clients, retail customers, or patients at the dwelling; a use crossing that line loses its home business status and becomes an unpermitted commercial use under the zoning district's regular use table instead. Table 8-2.4 separately confirms that home businesses, absent this exclusion, are otherwise permitted in every zoning district on the island. Enforcement runs through the Planning Department: a use found to exceed the frequent-visits limit is treated as a zoning violation subject to the penalties in § 8-3.5, because it no longer counts as the by-right home business the table allows.
Violations & Fines
A home occupation that draws frequent public visitors, or operates as a shop or clinic, forfeits its home business classification and becomes an unpermitted commercial use under § 8-1.5. Violators face a misdemeanor fine of up to $2,000 per day of continued violation under § 8-3.5, plus civil fines the Planning Director can impose up to $10,000 and $10,000 for each additional day, enforceable by a property lien after 90 days unpaid.
