Signage Rules: San Ramon vs Walnut Creek

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.

Home occupations in Walnut Creek are prohibited from having any exterior signage advertising the business. The home must retain its residential appearance from the street — no signs, banners, window lettering, illuminated advertising, or similar displays visible from outside the dwelling.
