A parcel is an officially described piece of land. A parcel is also sometimes referred to as a land lot. A parcel or land lot is legally considered an immovable piece of property. It is possible for a piece of land to be separated into different parcels and each parcel could have a different owner. Most parcels of land are subject to real estate tax just like the home or business that sits on the property. A parcel has defined, specific boundaries that will distinguish one parcel of land from other parcels next to it. Sometimes a professional conveyor can be used to determine where the legal boundaries are located between individual parcels of land or land lots. The conveyer will use GPS tools to map out exact coordinates for each parcel.
