Kauai County, HI Sign Regulations: Window Signs (2026)

The window-sign limit is one line inside a longer signage article that supplements Chapter 8's countywide Outdoor Sign Ordinance (§ 15-4) with Rice Street-specific design rules; both apply together, so a sign legal under § 15-4 can still be rejected here for blocking a storefront window. Section 10-5A.7(p) only allows signs mounted flat against a façade, projecting signs, or hanging signs, and requires the design of any sign to be compatible with the building's architecture rather than dominate the façade. Sign material is limited to non-reflective metal or wood with a carved, sandblasted or painted design, and lighting must be indirect, ruling out backlit plastic panels.

A projecting sign must clear at least eight feet above the sidewalk and cannot extend past the roof, overhang or awning it is mounted on. Because the ten percent façade cap and the window-visibility rule sit in the same subsection as the building-material and lighting standards, the Planning Department reviews all of them together when a Rice Street business applies for a sign permit, and a design that technically meets the ten percent area cap can still be sent back if oversized product graphics are covering the glass itself. That combined review is what distinguishes SPA-D from the rest of the county, where the Outdoor Sign Ordinance alone controls.
