Summary
Vallejo bars any sign, name plate, or advertising for a home-based business, including window displays of products or business materials. Section 16.321.04(K) makes the prohibition absolute: unlike most home occupation codes that allow a small nameplate, Vallejo permits none at all.

Full Breakdown
04(K), Signage, states the rule in full: there shall be no signs, name plates or other forms of advertising such as products displayed on the premises including windows in which a home-based business is conducted, and window display of materials associated with the home-based business is prohibited. The chapter draws no distinction by business type or sign size; a single small nameplate identifying the business is treated the same as a full advertising sign, both are banned. 04(F)'s bar on alterations not customarily found in similar dwellings, so signage is one piece of a broader effort to keep a home-based business invisible from the street. 509.
Violations & Fines
Posting any sign, name plate, or advertisement, or displaying business products or materials in a window, for a home-based business violates Section 16.321.04(K). Because Section 16.321.04(O) classifies the breach as a public nuisance, the city can pursue abatement under Chapter 16.615 and revoke the home-based business permit issued under Section 16.321.02 rather than merely require the sign's removal.
