If you own two or more adjacent parcels of land that you wish to combine into one parcel, you will need an experienced surveyor to draw up a lot consolidation plat that will to satisfy the requirements of local jurisdictions and for your protection as a property owner.
NOTE: Most local zoning authorities make lot consolidation a reasonably simple matter. A professional surveyor will do the fieldwork on the current lots, then draw up a plat that accurately shows the existing lots and the dimensions of the new plot of land. While some local governments allow lot consolidation with a simple letter of intent, it is always in your best interests to have your land professionally platted.
