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.
The Concord Development Code home occupation standards strictly prohibit exterior signage or advertising of any home-based business. This includes wall-mounted signs, window decals identifying the business, yard signs, flags, banners, A-frame sidewalk signs, and illuminated displays. The rationale is to preserve residential neighborhood character and avoid commercial intrusion into residential zones. One personal vehicle displaying business lettering or a logo is generally permitted if the vehicle is a standard passenger vehicle (not a commercial-classed truck or large van over a certain weight) and is parked on the property or legally on the street. Vehicles with roof-mounted signs, extensive wraps, or prominent commercial displays may be restricted under oversized vehicle or commercial parking rules. Online advertising (website, social media, directory listings) is permitted and does not constitute exterior signage. Addresses may be listed online. Violation of the no-sign rule can result in code enforcement citations starting at $100, escalation to $500, and revocation of the Home Occupation Permit. Signs on the interior of windows that are not visible from the street and that identify the business may be restricted in some interpretations; generally, no identification should be visible from outside the dwelling.
