As of the NYC Department of Health & Mental Hygiene's 2021 report, 2,850 active mobile food vending permits were issued for "hot dog" or "general" carts—the iconic stainless steel pushcarts with umbrellas.
The "dirty water dog" (simmered in seasoned bath) with sauerkraut, onions, mustard is a $2–4 NYC ritual. Carts operate 24/7 in shifts. Vendors: largely immigrants (Bangladeshi, Egyptian, Afghan, Dominican)—micro-entrepreneurs in a regulated sidewalk economy.
Post-COVID, permit numbers fluctuate. Check DOHMH Mobile Food Vending for latest data, applications, and rule changes (e.g., 2023 sidewalk widening pilot).
