Summary
Residents of unincorporated San Joaquin County can post a 'No Soliciting' sign at the entrance to the property, which permitted solicitors must honor under county ordinance. There is no countywide formal no-knock registry, but posted signs carry the same legal force. Religious, political, and charitable canvassing retain First Amendment protections regardless of signs.
Except as provided in subdivisions (u), (v), and (x), and Section 602.8, a person who willfully commits a trespass by any of the following acts is guilty of a misdemeanor:
(m) Entering and occupying real property or structures of any kind without the consent of the owner, the owner's agent, or the person in lawful possession.
(n) Driving a vehicle, as defined in Section 670 of the Vehicle Code, upon real property belonging to, or lawfully occupied by, another and known not to be open to the general public, without the consent of the owner, the owner's agent, or the person in lawful possession. This subdivision does not apply to a person described in Section 22350 of the Business and Professions Code who is making a lawful service of process, provided that upon exiting the vehicle, the person proceeds immediately to attempt the service of process, and leaves immediately upon completing the service of process or upon the request of the owner, the owner's agent, or the person in lawful possession.
(o) (1) Refusing or failing to leave land, real property, or structures belonging to, or lawfully occupied by, another and not open to the general public, upon being requested to leave by (1) a peace officer at the request of the owner, the owner's agent, or the person in lawful possession, and upon being informed by the peace officer that they are acting at the request of the owner, the owner's agent, or the person in lawful possession, or (2) the owner, the owner's agent, or the person in lawful possession.
Full Breakdown
San Joaquin County does not maintain a centralized do-not-knock registry, but the county solicitation ordinance gives legal effect to posted no-soliciting notices. A sign at least 3 inches by 4 inches reading "No Soliciting" or equivalent language, posted at the main entrance, walkway, or driveway entrance of a dwelling, creates an affirmative duty for commercial solicitors to bypass the residence. Violation by a permitted solicitor is both an ordinance violation and potentially a trespass under California Penal Code §602(o) (refusing to leave posted property after request). The sign's effect is strongest against commercial canvassing; religious, political, ideological, and charitable canvassing are constitutionally protected under Watchtower v. Stratton and Martin v. City of Struthers, so a No Soliciting sign cannot legally exclude non-commercial speech, though most nonprofit canvassers honor the signs by practice. Residents experiencing repeat violations can file a complaint with the SJ Sheriff's Office identifying the permitted solicitor's employer and ID card number.
Violations & Fines
Ignoring posted no-soliciting sign: $100–$250 infraction first, $250–$500 repeat, permit revocation on third offense within 12 months. Criminal trespass (refusing to leave): misdemeanor PC §602(o).
