The printed Allegany County plat book and the online parcel map answer the same question, who owns the land near Andover, in different ways. This guide covers finding a printed edition for Allegany County, New York, and using the free parcel map in the meantime.
How to use the Allegany County plat book
A plat book, sometimes called a land atlas, shows each township in Allegany County as a page, with ownership blocks labeled by owner name and rough acreage. It's different from a recorded plat, which is the official survey drawing for a subdivision in Amity filed with the county.
Step one: the free Allegany County viewer
For land around Belmont, open the Allegany County Beacon site (Schneider Geospatial's Beacon platform); it is the map Allegany County itself publishes. Search a Belmont address on the county search page, read the report, then jump to the map to see that parcel's outline. Bookmark our Allegany County page too; it tracks the official New York link if it moves and lists the maps around Andover.
Current and older editions
Private publishers have printed plat books for many rural counties, but editions for Allegany County come and go; inquire at the courthouse, the extension office or a farm supply store in Amity. Collectors and genealogists prize old Allegany County atlases since they display farm names and owners near Stannards long before online maps.
From Belmont to the back roads
Town lots cluster around Belmont, the county seat, and Alfred, Allen, Alma, and Almond. Smaller places such as Stannards appear on the county map as little clusters of lots. Roughly 1,029 square miles of land and about 46,651 residents (2023 estimate) make up Allegany County. The Allegany County map mixes subdivision lots near Allen with farm and wooded tracts farther out.
Deeds and plats behind the Allegany County map
The parcel layer for Allegany County points back to recorded deeds and plats, kept by the county's recording office (its title varies by state). Easements and access rights near Andover live in recorded documents, so read the deed, not just the county map.
Reading an Allegany County atlas page
Plat book pages for Allegany County generally include an index of owners, so you can find a family name near Belmont without knowing the township. Small parcels and town lots in Almond are often too small to label on an atlas page, which is another reason the online map is better for them. For a land purchase near Belmont, rely on the county parcel record and a title search, not an atlas.
Making your own atlas of Allegany County
Farm families near Amity often keep successive editions of the Allegany County plat book, which together display how ownership shifted over decades. Some buyers print the county parcel map at township scale to carry on back roads near Almond.
