Charco Special Events & Permits: Block Party Permits Rules (2026)

Residents seeking to hold block parties on county-maintained roads in unincorporated Pima County must apply for a temporary street closure permit through Pima County Department of Transportation (PCDOT). The application typically requires signatures or consent from a majority of affected property owners on the block, a traffic control plan showing barricade placement and emergency vehicle access routes, and proof of liability insurance. PCDOT evaluates requests based on traffic impact, emergency access, and duration. Applications should be submitted at least 30 days in advance. Events with amplified music or sound must comply with ARS 13-2916 nuisance standards. Block parties in HOA communities on private streets do not need county road closure permits but must comply with HOA CC&R event provisions. Food service at block parties with shared food is generally exempt from health permits when no sales occur, but any food sold requires Pima County Health Department temporary food establishment authorization. Alcohol service at block parties on public streets is subject to Arizona Department of Liquor Licenses and Control regulations.
