Kirkland, WA Home Business: Signage Rules (2026)

65(4)(i) restricts exterior identification for a home occupation to a single sign: one building-mounted sign, which must be non-illuminated, capped at a maximum size of two square feet. The provision states that a home occupation 'has no exterior indication' other than that one sign, meaning freestanding yard signs, window signs, awning graphics, banners and any illuminated or electronic signage are all prohibited for a home-based business, regardless of the property's underlying zone sign allowance for other uses. The limit sits inside the same subsection 4 standards that cap a home occupation's floor area at 500 square feet, restrict it to one commercial vehicle, and bar outdoor storage, all aimed at keeping a home business from reading as a commercial property to neighbors and the street.

65(5); that process addresses traffic, storage, noise and neighborhood-character standards, not signage size. Because the standard is written as an outright cap rather than a permit threshold, a home occupation operator who wants more visible identification must instead seek a change of use to a fully commercial designation in an appropriately zoned property. 12 KMC, Code Enforcement, alongside the section's other standards.
