Knox County Commissioners voted Monday to regulate "transient vendors."
They adapted the definition to mean any person selling or offering merchandise to the public from a "temporary premises."
Those include any public space, hotel, vacant lot, railroad car, motor vehicle or storeroom.
The new law means any transient vendor must now purchase and display a $50 temporary use permit from the Department of Codes Administration and Inspections.
According to the law, the change comes in response to complaints from the public about unregulated roadside flea markets impeding the vision of motorists and presenting an "eyesore" for the city.
The law was proposed by Commissioner R. Larry Smith, who says it provides exemptions for people selling produce.
