Concord, CA Home Business: Signage Rules (2026)

Concord's home-business signage rule is absolute. ' Read together with paragraph 11 (Nuisances), which requires the business to be 'invisible to the neighborhood,' the prohibition covers wall signs, yard signs, A-frames, banners, window decals, illuminated signs, sandwich boards, sample displays, and any structure erected to identify or advertise the business. The vehicle rule in paragraph 6 reinforces the no-identification principle by separately barring any business vehicle that 'give[s] the appearance that a business is being conducted at the location' - so vinyl-wrapped or logo-painted commercial vehicles parked in the driveway can trigger the same enforcement as a yard sign.

180 (Sign Standards), which is the general citywide sign code. Because the prohibition is a use restriction in the residential standards chapter rather than a sign-code regulation, there is no master sign program, no minor variance, and no administrative exception pathway that authorizes on-site identification of a home occupation. Operators may continue to use ordinary residential address numbers and standard mailbox markings; they may distribute business cards, advertise online, and operate registered fictitious business names under California Business & Professions Code Section 17910 - but they may not display the business name, logo, or any commercial signage at the dwelling.
