Undeveloped land in United (PA) is open to almost unlimited business possibilities; depending on the location of its region there may be municipal zoning restrictions within United (PA) city limits or residential neighboring areas, for example most cities frown upon setting up a slaughter house in the suburbs or building apartment complexes in a residential United (PA) neighborhood whose occupants own their dwellings (owners may want to keep out renters). Careful research is needed prior to signing contracts.
