Chino FAQ
Can I put a small sign in my window advertising my home business?
No. CMC Title 20 home occupation conditions require no exterior evidence of the business, which includes window signs. CMC Title 17 likewise does not permit commercial advertising signs in residential zones.
Is a work-truck with my company name parked in my driveway a sign violation?
A registered, operational vehicle with company lettering parked in a legal driveway is generally treated as an incidental vehicle, not a sign. Inoperable vehicles or those parked to function as advertising (e.g., on the front lawn) violate parking and zoning code.
Can I put a yard sign on the public parkway pointing to my home business?
No. Signs in the public right-of-way without an encroachment permit are prohibited under CMC Title 11 and are subject to summary removal.
San Bernardino FAQ
Can I put a sign on my house advertising my home business?
Not in standard residential zones. A home occupation must have no exterior evidence of the business, including signage.
What about lettering on my work truck?
Typical business lettering is fine, but large wrap advertising on vehicles parked overnight in front of the home may draw code enforcement as a de facto sign.
Are temporary event signs allowed?
Yes within strict size and time limits under the general sign code, and never in the public right-of-way without a permit.
