Signage Rules: Martinez vs San Ramon

Martinez prohibits exterior signage advertising home-based businesses in residential zones. The Zoning Ordinance's home occupation standards are explicit that the business must not be visible from the public right-of-way, which includes no window signs, yard signs, banners, or exterior lighting that identifies the business. This rule preserves residential neighborhood aesthetics and is strictly enforced.

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.
