Summary
In the City of Gilroy, a home occupation permitted under Gilroy City Code § 30.40.20 may not display show windows, window displays or advertising signs, structures, or vehicles on or near the site designed to attract customers, clients or the public. Any change to the home's outside appearance signaling a business is also barred under subsection (c).
Any professional or business activity, except those listed in section 30.40.40, is permitted in a dwelling unit as a home occupation only where such use meets all of the following criteria: ... (c) There shall be no change in the outside appearance of the building premises, visible evidence of the conduct of the home occupation, or construction feature or alteration not of a residential character. (d) There shall be no show windows, window displays or advertising on signs, structures, or vehicles on or near the site designed to attract customers, clients or the general public to the premises.
Full Breakdown
Article XL allows a home occupation, defined as a use clearly incidental and subordinate to the dwelling's residential purpose, in any residential, commercial or agricultural district, but only where the activity meets every criterion listed in § 30.40.20. Subsection (c) bars any change in the outside appearance of the building, any visible evidence that a business is being conducted there, or any construction feature or alteration that is not of a residential character. Subsection (d) goes further specifically on advertising: it prohibits show windows, window displays, or advertising on signs, structures, or vehicles on or near the site that are designed to attract customers, clients or the general public to the premises.
Read together, these two subsections mean a Gilroy home-based business cannot put up a yard sign, a lit window display, a wrapped vehicle parked to draw attention, or any exterior signage naming the business, even if similar signage would be allowed for a standalone commercial use in a business district. The home occupation is also confined to the main building, cannot generate pedestrian or vehicular traffic beyond what is normal for the neighborhood under subsection (g), and may not be open to the public under subsection (e).
A use that cannot meet every § 30.40.20 criterion, including the no-advertising rule, may instead seek a conditional use permit from the planning commission under § 30.40.30, or is barred outright if it appears on the § 30.40.40 list of uses never permitted as home occupations.
Violations & Fines
Displaying an advertising sign, window display, or business-branded vehicle at a Gilroy home occupation violates § 30.40.20(d) and, under § 30.40.50, causes the home occupation to fail conformance: the use must immediately cease and all permits tied to it, including the business license, become immediately null and void until compliance is restored.
