Jurupa Valley, CA Special Events & Permits: Block Party Permits (2026)

Holding a block party that involves closing a public street in unincorporated Riverside County requires a temporary street closure permit from the Riverside County Transportation Department. Applications should be filed at least 30 days in advance and include: a Traffic Control Plan compliant with MUTCD/Caltrans standards, signed support from at least 51-75% of residents on the affected block, a certificate of liability insurance ($1 million general liability typical) naming the county as additional insured, and a safety plan addressing emergency access. Permit fees typically range from $75-$250 plus any Sheriff standby costs. Alcohol service requires a separate ABC Daily License. Amplified sound over ambient must comply with Ord. 847 noise limits or obtain a variance. Events in cul-de-sacs or on private HOA streets may not need county permits, only HOA architectural/events committee approval. Non-commercial, invitation-based gatherings without street closure typically need no permit. Fire lanes and driveways must remain accessible for emergency vehicles at all times — 20 feet minimum clear path.
