Parcel System

The staff in the Mapping Division are available to explain the information we have used to map a particular parcel boundary; however:
  • We do not survey property. If you need a surveyor, there are many qualified people listed under “Surveyors” in the yellow pages of the phone book.
  • We do not provide legal advice on property rights or any other subject.
  • We do not research or determine whether particular parcels have access. This must be researched by the interested party at the Lyon County Recorder’s Office.
  • We do not have the ability to settle disputes between property owners as to whether an encroachment has occurred with regard to fences, sheds or any other use or structure.
  • We do not keep records on building setback requirements. The Building Department of Lyon County can give you that information for your particular parcel.
  • We do not have topographic surveys in our office. If you are required to have a topographic survey for a building permit or Certificate of Occupancy, you must hire a surveyor to do this for you and fill out an Elevation Certificate.
  • We do not keep FEMA Flood Plain maps in our office. For information on whether your property falls within a flood plain, contact Lyon County Planning Dept.
