Summary
Unincorporated San Mateo County does not designate specific food truck vending zones but restricts operations through general zoning and parking rules. Food trucks may not vend from the public right-of-way for extended periods (not a permitted commercial use), must comply with parking time limits on County roads, and cannot operate within 500 feet of a school during school hours per Education Code §49535.5. Private property vending requires property owner written permission and may trigger a use permit.
Existing law authorizes a local authority, by ordinance or resolution, to adopt requirements for the public safety regulating any type of vending and the time, place, and manner of vending from a vehicle upon a street. This bill would prohibit a local authority, as defined, from regulating sidewalk vendors, except in accordance with the provisions of the bill. The bill would provide that a local authority is not required to adopt a new program to regulate sidewalk vendors if the local authority has established an existing program that substantially complies with the provisions of the bill. The bill would apply these provisions to a chartered or general law city, county, or city and county. T
Full Breakdown
Unlike many California cities, unincorporated San Mateo County has no dedicated mobile vending zones. Food trucks on County roads are subject to standard parking regulations (72-hour max under CVC §22651(k) if not moved). Vending on the public right-of-way for more than brief periods requires an Encroachment Permit from Public Works and is rarely granted. Vending on private property (commercial lots, parking areas, construction sites) is allowed with the property owner's written permission, provided the zoning permits the use: this typically means commercial (C) or industrial (M) zoning; residential and agricultural zones do not permit food truck vending.
SB 946 (California Sidewalk Vendors Act, 2019) preempts local bans on sidewalk food vending (pedestrian, not vehicular) but does not affect parked food trucks. 5. County franchise food truck events (outside schools, on construction sites, office parks) commonly operate under 3-4 hour scheduled blocks with rotating locations.
Violations & Fines
Vending on public right-of-way without encroachment permit: $100-$500 per occurrence plus required relocation. Vending on residential parcel: zoning violation $100-$1,000 per day. Within 500 ft of school during school hours: Ed Code §49535.5 violation, immediate relocation. Blocking fire hydrant or driveway: tow at owner expense.
