The accuracy of the property lines varies depending on several factors. In general, the newer a subdivision is, the more accurate the mapped lines are. In a newer subdivision that has been established in roughly the past 15 years, the lines are generally within 5 feet +/- of where they actually exist. In an older, more rural portion of the county, the property lines may not have been surveyed in many years or decades. Those lines could have been mapped according to fence lines or other various assumed physical representations of where the property lines were thought to exist at the time.

Today we rely on deeds and plats of record to map the property lines. In areas of concern, these records are checked to re-map areas that appear to be inconsistent. The property lines in LINK-GIS are not a survey and are not intended to represent actual surveyed property lines – only a licensed surveyor can authoritatively map property boundaries. The Property Valuation Administrator (PVA) is the authority on property boundary and parcel data.
