Cook County does not maintain a formal no-knock registry for unincorporated areas. Homeowners can post 'No Soliciting' signs. Solicitors who ignore posted warnings may face trespass charges under Illinois law.
Cook County does not operate a formal no-knock or no-soliciting registry for unincorporated areas. Homeowners wishing to avoid door-to-door solicitation can post 'No Soliciting' signs on their property. Under Illinois criminal trespass law (720 ILCS 5/21-3), a person who remains on private property after being asked to leave or ignoring posted 'No Trespass' signs may be charged with criminal trespass. The Cook County Sheriff's Office can be contacted for persistent or aggressive solicitors who ignore posted warnings. Many incorporated municipalities within Cook County operate their own no-soliciting registries (such as Evanston and Schaumburg), but these do not extend to unincorporated areas.
Ignoring No Soliciting sign: potential trespass charge under 720 ILCS 5/21-3. Repeated intrusion: harassment complaints possible.
