Berkeley residents can post No Solicitation or No Knock signs at their door. Ignoring a posted sign during door-to-door commercial activity exposes the solicitor to trespass enforcement.
California law and Berkeley practice recognize that posted signs such as No Solicitors, No Trespassing, or No Knock create constructive notice to commercial canvassers. Once a sign is clearly posted at the entry, a commercial solicitor who knocks or rings anyway can be cited for trespass under California Penal Code 602(o) or related sections, and the City may act on repeated complaints. Federal Do Not Call rules (47 CFR 64.1200) are separate and cover telephone calls, not in-person visits. Non-commercial canvassers (political, religious, charitable) have broader First Amendment protection and are not automatically bound by No Solicit signs, but are still obligated to leave when asked. Residents can track recurring violators and provide descriptions to Berkeley Police for enforcement.
