Cook County prohibits public urination through Health Ordinance Ch. 42 sanitation rules and Ch. 58 disorderly conduct provisions in unincorporated areas. Suburban Cook municipalities and Chicago issue their own citations; repeat offenses can trigger sex-offender questioning, though Illinois generally does not register first-time offenders.
Public urination in suburban Cook is enforced primarily through municipal nuisance and disorderly conduct ordinances. Cook County Code Ch. 42 (Health and Sanitation) bars depositing human waste outside approved sanitary facilities, and Ch. 58 (Offenses) reaches the same conduct as disorderly conduct in unincorporated Cook. Chicago Municipal Code 10-8-485 carries a $100 to $500 fine. Illinois does not normally trigger sex offender registration for routine public urination unless the act includes lewd exposure under 720 ILCS 5/11-30. Illinois courts have rejected attempts to charge isolated incidents as indecent exposure absent intent to arouse. Forest Preserve District police enforce Ch. 90 rules separately within preserve boundaries.
Citation under Cook County Code Ch. 42 or Ch. 58 carries fines from $50 to $500 per occurrence. Lewd-exposure charges under 720 ILCS 5/11-30 are Class A misdemeanors with possible jail. Forest Preserve violations add a separate Ch. 90 fine.
