Liberty City Sawmills is a company in Trenton, Portland Island, Liberty City in Grand Theft Auto III and Grand Theft Auto: Liberty City Stories that makes timber, wood and furniture. The company also has branches outside Liberty City. Drilling can always be heard when on the rooftop or the level right below the rooftop. It is the first building seen on the left after driving past Greasy Joe's Café (or Rusty Brown’s Ring Donuts as in GTA Liberty City Stories).
In GTA III, a hidden package can be found on the rooftop. It is only accessible from the back by jumping onto a large vehicle and jumping the fence. A Rumpo is usually parked near the northwest side of the building. There is also an armor pickup and an Uzi on the roof.
