Riverside County, CA Filming & Production: Street Closures (2026)

Closing a county road for filming in unincorporated Riverside County involves a multi-agency review. After the Film Commission issues the base filming permit under Ord. 447, the applicant submits a Traffic Control Plan (TCP) prepared by a California-licensed traffic engineer or certified TCP technician to the Transportation Department. Closures on major arterials or highways require Caltrans coordination if they intersect state routes. Sheriff's deputies are assigned for full-closure traffic control at prevailing-rate staffing costs; short-duration intermittent traffic control (ITC) stops up to 3 minutes may be staffed by certified civilian flaggers (per MUTCD). Notification requirements typically include door-hangers to affected residences and businesses 72 hours in advance, detour signage per Caltrans standards, and emergency access maintained at all times. Film Commission permits large closures only after review by Fire (for response access) and EMS (for medical access). Closure time on residential streets is generally limited to daytime unless the permit includes a night-filming variance.
