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.
Rialto FAQ
Can I put a small sign in my front yard advertising my home business?
No. Under RMC Ch. 18.78 and Title 18 home-occupation standards, business signage in residential zones is prohibited. The home occupation must produce no external evidence of business activity.
Is a magnetic sign on my truck OK if I park it at home?
Yes, personal-vehicle signage is not regulated as an on-premises sign. However, if the vehicle is a commercial vehicle exceeding RMC weight or size limits, parking it overnight in a residential zone may violate Title 10 vehicle / parking rules.
