Ontario, CA Curfew Laws: Park Curfew (2026)

Sec. and sunrise the next day. The City Council can move that closure earlier by resolution for a specific park to head off problems tied to activity there, but the earlier hour only applies once it is posted at the park. Two narrow exceptions exist: on-duty public officers or employees acting within the scope of their jobs, and anyone attending an organized athletic event or other function that has written permission or a permit from the Recreation Department, for the duration of that event plus one additional hour afterward.

Separately, Sec. 30 lets the Director, Police Chief, Fire Chief, or their designees close or restrict use of any park, recreation building, facility, amenity, or equipment at any time their discretion finds it needs immediate renovation, poses a hazard, or is a public nuisance, and that closure lasts only as long as the condition exists; remaining inside after such a closure is also a misdemeanor for anyone other than an on-duty public officer or employee. Sec. 31 layers on a camping ban: no one may camp in an Ontario park outside a Director-designated camping area, and even there a permit under Sec. 04 is required, with Fire Department review of access for medical and fire emergencies and compliance with the California Fire Code.
