In the ongoing negotiation between informal commerce and urban order, Saudi Arabia's Ministry of Municipalities and Housing has drawn a precise boundary: nine categories of high-stakes locations where mobile vendors may no longer operate. The decision, announced in August 2026, reflects a city-planner's calculus — that the flow of emergency vehicles, the safety of intersections, and the dignity of accessible spaces carry a weight that street commerce cannot override. It is not a silencing of the vendor economy, but a mapping of where its presence becomes a public cost.
