New York Plat Maps
New York plat maps are recorded locally, county by county or town by town. The state index is the way to find the right office.

The search
People type "New York Plat Maps" when they want one map for the whole state. New York plat maps are county clerk records. New York City is five counties, not one book.
Where the sheet is kept
There is no single statewide plat book that replaces the local recording. A subdivision plat is filed where that state's land records are kept. The public parcel layer on a county or state viewer is an assessment map.
Open the directory
Start at the New York page on Platbookmapper. Pick the county, parish, borough, or independent city named in the deed. Then open the official viewer linked there when one is listed.
What the search will not do
A state plat-map search will not draw your lot line, and it will not turn a tax map into a survey. Use the recorded plat for the subdivision, and a licensed surveyor when the boundary is the question.
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.
