Parcel maps are developed primarily from property tax records and deeds. Even though they display 'boundaries' on a map, they are not surveys and should not be used for locating property lines and corners.
Parcel maps can be a helpful reference tool for visualizing properties, but their accuracy is not guaranteed. We have encountered situations where our parcel map was off by more than 100 feet. This can happen because we did not have a lot of precise survey and GPS information when parcel maps were first developed. As new survey and GPS information is received, maps are adjusted to be more precise.
If you're concerned about inaccurate information on a parcel map, please contact us.
