First Valve in the Driveway which is called as Curb Stop / Water-Shut Off Valve. You need a plumber and a special key to open / close this valve. This can stop water supply for the unit
Second Valve should be in the basement water supply, most likely a Blue valve. This will also stop the water supply to the Unit. This is the primary water shut-off valve use to stop water supply.
Note: In case of emergency to avoid flooding you must ensure both the valves are in good working condition
