Guide: A parcel map is not a survey
About property lines
Property lines on a map come from the county parcel layer, which is drawn from deeds and surveys but is not a survey itself. It is accurate enough to see the shape and rough size of a lot and which neighbors touch it. Only a licensed surveyor can mark a legal boundary on the ground.
