Sullivan Tax Maps Are a Reference, Not a Survey
Sullivan County property research can start with tax maps, but the county warns they are reference and location tools.

Sullivan County maintains and publishes its tax maps for reference and location checks. A map is not a boundary guarantee.
Use the tax map to find the parcel and city or town. If you are planning a driveway, fence, septic layout, or lot split, use a survey, deed, and local approval for decisions that affect money or construction.
Save the Sullivan County tax map with the property address and parcel number, but do not use it as a survey. Take a boundary question to the proper record or professional instead of asking the map to prove more than it shows.
