San Joaquin County, CA Food Trucks & Mobile Vendors: Vending Zones (2026)

Location rules for mobile food facilities in unincorporated San Joaquin County combine state preemption with local ordinance. California Vehicle Code §22455 allows cities and counties to regulate stopping, standing, and vending from mobile food trucks on public streets — the county restricts stopping in residential zones to no more than 10 minutes per location except when actively serving customers. A 500-foot buffer from K–12 school campus property lines during school hours (typically 7 AM–4 PM school days) is enforced to reduce student-traffic conflicts, and operations within 200 feet of a licensed restaurant on the same side of the street face code compliance scrutiny (some non-preemptable limits apply). On private property, MFFs may operate with the written consent of the property owner in commercial (C-1, C-2, C-G) and industrial (M-1, M-2) zones; a Temporary Use Permit is required for regular multi-vendor lots ("food truck courts"). California SB 946 (Gov Code §§51036–51039) preempts local bans on sidewalk vending (foot-based pushcarts) but does NOT apply to motorized food trucks. County parks and Port of Stockton facilities require separate concession permits. Tracy Municipal Airport and Stockton Metro restrict vending airside.
