Want a copy of the Warren County plat book? A plat book shows owners and tract lines on township pages, popular with hunters, farmers and buyers near Kattskill Bay. What this Warren County guide covers: how the atlas is organized, where to look for printed copies, and the free online map that stays current.
Getting started with the Warren County plat book
On ground around Horicon, a plat book is a privately published atlas, that map ownership across the countryside, usually township by township.
Where the parcel data lives
Property in and around North River appear on the NYS Tax Parcels Public layer in ArcGIS Map Viewer, a viewer that needs no account. If you only know roughly where the land is, pan along the nearest road and click the parcel itself, for land near East Lake George included. Out toward East Lake George, write down the parcel ID before closing the panel; every records desk in the county uses it to find the file.
Printing your own
Screenshot each section of the viewer around Hague and keep them in a binder for the truck.
How land is described here
Rural deeds near North River are often described by metes and bounds, listing bearings, distances and landmarks. Town lots near Horicon are typically described by lot and block, making them easier to find. Write down the legal description for the tract near Hague for any title or survey request.
Offices that can help
If the acreage or value on a parcel near Horicon looks off go to the county Real Property Tax Services office, the office behind the parcel record. Building or septic questions for a lot near Brant Lake are for the local planning and health departments, town or county, depending on location.
Taking the map into the field
Most viewers work in a phone browser, useful out on a road near Chester, so load it before you lose signal. A printout of the tract near Johnsburg keeps working without signal.
Where the recorded documents are
Before you sign anything, pull the recorded deed through the County Clerk; the parcel line is a drawing of it, whether the land is near Horicon or elsewhere in the county. For property near Hague, use the document number from the tax record to skip a name search.
Land on the county line
Warren County borders Essex County, Hamilton County, Saratoga County, and Washington County, all with their own assessor records. Acreage along the edge near Lake George can show up in two county records, so check the adjacent map before you assume the acreage. For a tract near Oneida Corners, our state page links every bordering county map for New York.
A quick look at the area
Smaller places on the map include Bolton, Chester, Hague, and Horicon, each with its own cluster of lots. Around 65,380 people call Warren County home (Census estimate, 2023) across about 867 square miles. Warren County was formed in 1813, and some chains of title near North River are long.
Where to look for one
Libraries near Kattskill Bay sometimes keep past atlases, which helps when tracing a farm's history.
Using the parcel viewer instead
The NYS Tax Parcels Public layer in ArcGIS Map Viewer is updated more often than any atlas, for tracts near Brant Lake.
A word on accuracy
Acreage on the record is a tax-roll number; just a licensed surveyor can set the real corners for a parcel near Bolton. For acreage around North River, records update in batches, so a deed recorded last month can take weeks to appear.
Not the same thing
For a tract near Hague, a plat book is not a recorded plat: the recorded plat at the County Clerk is a legal document, and the atlas is just a guide.
Why people still buy them
Buyers and seed dealers around Hague rely on them to see ownership across many tracts at once.
