The Borough Council introduced an ordinance Monday that limited the places where cannabis businesses can open in the county seat.
If it passes after a public hearing March 27, the shops will not be allowed to open downtown or in the Stangl Road area.
The shops will only be allowed on state highways or county roads, the ordinance says.
But Borough Administrator Michael Humphrey told the Council that he is getting phone calls from cannabis businesses, which have already received state approval, looking to locate in Flemington and are in the "pre-leasing" stage.
He said they are eying spaces, including the vacant Rite Aid at Route 31 and Church Street, the former Red Crab Juicy Seafood on the Flemington Circle and the former 30 Burgers next to Burger King on Route 202.
Flemington has only four cannabis licenses, two for medical sales and two for recreational sales. One location can have both medical and recreational sales.
