Antioch FAQ
Can I put a small sign on my front lawn for my home bakery?
No. Any exterior signage advertising the home business is prohibited, including small yard signs. Rely on online marketing and business cards instead.
My work truck has my company logo - can I park it in the driveway?
Yes, one personally-used commercial vehicle under 1-ton GVWR may be parked on site. Enforcement issues arise when multiple branded vehicles or trailers are parked as de facto advertising.
El Cerrito FAQ
Can I hang a small plaque with my business name?
No. Any external indication of commercial activity violates the home-occupation rules. Interior business identification not visible from the street is acceptable.
What about a logo on my work truck parked in the driveway?
A modest logo on a personal/work vehicle is generally tolerated; however, oversized body wraps or commercial trucks (>10,000 lb GVWR) parked overnight may violate residential parking and home-occupation rules.
