Santa Clara, CA Soliciting & Door-to-Door: No-Knock Registry (2026)

Santa Clara Municipal Code recognizes the right of residents to prohibit door-to-door solicitation by posting clearly visible No Solicitation, No Soliciting, or No Trespassing signs at the property entrance or front door. Under the ordinance and California trespass law (Penal Code 602.1), commercial solicitors who approach and knock at a residence posted with such a sign commit a violation and can be cited or arrested for trespass after notice. Signs should be posted in a location reasonably visible from the approach path, such as near the front door, on a gate, or on a mailbox. The ordinance provides First Amendment accommodation for non-commercial speech including religious, political, and charitable canvassing, which may knock even at posted homes but must immediately leave if asked. Residents should report violations to Santa Clara Police with the solicitor's name, company, and description. The city does not maintain a formal Do Not Knock registry but treats posted signs as legally equivalent notice.
