Ontario, CA Public Conduct: Loitering Rules (2026)

04, part of Chapter 7's curfew and daytime loitering scheme, bars any minor "who is subject to compulsory full-time education or to compulsory continuation education under State law" from remaining in a public street, highway, road, alley, park, playground, other public ground, public building, or the premises of any establishment or vacant lot, away from home, during the hours and days when the minor's school is in session. The section lists eleven exceptions: accompaniment by a parent, guardian, or other adult with custody; an emergency errand a parent or guardian directed; going to or from lawful employment; going to or from a medical appointment; a student with a valid off-campus lunch permit; going to or from a compulsory alternative education program; attending or returning directly from an official school, religious, or government-sponsored activity; attending or returning directly from an event tied to a parent's or guardian's medical condition; enrollment in home schooling; exemption from compulsory education by law; and an absence authorized under Education Code Sec.

48205 or other state or federal law. Adopted by Ordinance 2603 in 1995 and amended through 1999, the section targets school-hours loitering by minors rather than adult loitering; Ontario's police officers and school resource officers enforce it during the school day. As with the nighttime curfew in Sec. 02, a repeat violator can be assessed a police services fee under Sec. 05.
