A proposal by new Mayor Daniel Lurie and State Sen. Scott Wiener seeks to crack down on vendors fencing goods on city streets.

San Francisco leaders are again trying to crack down on illegal street vending by allowing police to take stronger action against vendors who sell stolen goods. Why it matters: Fencing — the illegal sale of stolen items — has been an ongoing issue in San Francisco in many neighborhoods with high foot traffic,

Under the new legislation, any vendor selling commonly stolen items on a designated list would need to show a permit or proof of purchase, or police can confiscate the goods or issue citations.

Mayor Daniel Lurie is collaborating with state Sen. Scott Wiener, D-San Francisco, on a bill that would increase penalties for those involved in illegal fencing operations, which is when stolen merchandise is later resold for a profit.
