What Is a Zero Lot Line
A zero lot line product places one wall of the house on a side lot line, with the open yard on the other side.

The plat or a recorded declaration has to allow it. There is often a maintenance easement on the neighbor's lot so the owner can repaint that wall.
On the recorded sheet
Look for a note that names the zero side and the easement width. The wall on the line is intentional, not an encroachment.
The mix-up to avoid
Building on the line without that note is a different problem. The plat is where the permission is written.
Find the county map
Open Platbookmapper and pick the county that taxes the land. Use that viewer to get the parcel ID, then match it to the recorded plat if you need the easements and lot numbers.
Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey.
