Signage Rules: Concord vs San Ramon

Home occupations in Concord may not display any exterior signs, window signs, or outdoor advertising identifying the business. The residential character must be preserved. Vehicle lettering on one personal vehicle is generally permitted if the vehicle is a standard passenger type.

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.
