Rancho Cucamonga, CA Curfew Laws: Juvenile Curfew (2026)

Rancho Cucamonga Municipal Code Chapter 9.16 establishes a juvenile curfew prohibiting minors under the age of 18 from being present on public streets, sidewalks, parks, and other public places between 10:00 PM and 5:00 AM (or sunrise, whichever comes first), with a slightly earlier weeknight curfew in some jurisdictions and later hours on weekends depending on the adopted ordinance. Exceptions apply when a minor is accompanied by a parent, guardian, or adult 21 or older authorized by the parent; traveling to or from lawful employment; responding to an emergency; engaged in interstate travel through the city; exercising First Amendment rights to free speech and assembly; or attending an official school, religious, or other organized activity sponsored by Rancho Cucamonga or a community group. Parents who knowingly permit or encourage a curfew violation can be charged under parental responsibility provisions. Enforcement is handled by the Rancho Cucamonga Police Department (a contract with the San Bernardino County Sheriff at the Rancho Cucamonga Station), and violations are typically handled as infractions with community service or diversion programs for first offenses, escalating to citations for repeat violations.
