Chino Hills, CA Special Events & Permits: Block Party Permits (2026)

020 defines a 'block party' as an event where the residents of a neighborhood request to close their street to vehicular traffic in order to socialize and build neighborhood community, usually involving food and games. 030 confirms block parties are allowed on cul-de-sacs, through streets, and private streets, but adds one hard rule for the private-street case: the Homeowners' Association must be the applicant, not an individual homeowner. Applications go to the Community Development Department, and an Encroachment Permit is required because the event closes a street to traffic.

110, the application must be filed at least forty-five days, and no more than one hundred eighty days, before the event; the 180-day cap can be waived by the Director. 110(B). 100 requires the application to include, among more than twenty items, an estimated attendance count, a traffic and parking plan, a security plan, a sanitation plan, evidence of insurance, and, for any temporary structure like a tent or stage, a description of it. 150 if the organizer has not lined up enough traffic controllers, crowd monitors, or safety and sanitation resources, or if the event risks violent or disorderly conduct; a denial can be appealed to the City Council within ten days.
