San Bernardino County, CA Special Events & Permits: Block Party Permits (2026)

San Bernardino County's Highway Permit Code (Div. 51.01) makes it unlawful to place any obstruction or impediment to travel on a county highway, defined to include public streets in unincorporated territory, without a permit from the Road Commissioner (Director of Transportation). A neighborhood block party that barricades a residential street falls squarely under this rule. Public Works' fee schedule lists a dedicated Road closure permit fee of $732.00. This is separate from the Chapter 85.16 Temporary Special Event Permit, which covers the event itself and exempts small gatherings under 500 (Class I) or 200 (Class II) attendees, the street-closure permit is still required regardless of event size.
