Signage Rules: Richmond vs San Ramon

Richmond generally prohibits exterior signage for home occupations. The business must not be visible from the street, which includes signs, window displays, and advertising on parked vehicles routinely stored at the residence. This preserves the residential character of neighborhoods.

San Ramon prohibits all exterior commercial signage on home-business properties. No signs, banners, lighted displays, or window advertising that identifies a business are permitted. The business must be visually indistinguishable from a purely residential use from the street and neighboring properties.
