A posted No Solicitors or No Trespassing sign at an Ontario home is legally enforceable; solicitors who ignore it commit a misdemeanor under California Penal Code 602.5.
Residents in Ontario can protect their homes from unwanted commercial solicitation by posting a clear No Solicitors, No Soliciting, or No Trespassing sign at the front entrance. Ontario Municipal Code Chapter 5 makes it unlawful for any permitted solicitor to enter a property that displays such a sign, and California Penal Code 602.5(a) treats entry into a residence after being told to leave or after a posted sign as a misdemeanor trespass. Signs should be placed at eye level near the front door, gate, or driveway and use letters at least 1 inch tall to meet the standard of reasonable notice. Residents may also add individual addresses to the Ontario Police Department trespass letter program, which authorizes officers to make arrests on private property after hours without the owner present. The federal Do Not Call Registry and the California Consumer Privacy Act do not directly cover door-to-door visits, so the posted sign remains the primary residential defense. Violations can be reported to Ontario PD at (909) 408-1700; providing a photo of the badge helps enforcement.
