New York GIS Maps by County: The Parcel Viewer Each Uses

Which parcel map software each New York county uses (62 of 62 verified), how to search the common viewers, and a link to every official map.

Looking for New York county GIS maps? New York has 62 counties, and their official parcel maps do not all run on the same software. Knowing which viewer a county uses tells you what the search box expects and where the parcel details are.

New York City's five boroughs are each a county (Bronx, Kings, New York, Queens and Richmond), so they appear below under their county names.

If you look up land in more than one New York county, you will notice the parcel maps don't match. That is because each office chooses its own software. Below, all 62 New York entries in our directory are listed with the viewer each one uses, plus tips for the most common types.

New York at a glance

13 of these entries point to a statewide viewer rather than a county-run site (NYS Tax Parcels Public layer in ArcGIS Map Viewer). A statewide map is handy for crossing county lines, but the local office is still where deeds and tax records are kept.

The most populous counties

Most lookups happen in the largest places, so here is what their maps run on.

How to search the most common viewers in New York

county web map (22 entries, e.g. Bronx County, Broome County, Chenango County)

  1. Open the official map link from the county's page; it opens in a new tab.
  2. Accept any disclaimer, then look for a search box that takes street addresses, owners or parcel IDs.
  3. Zoom in and click a parcel to see its details.
  4. Use the map's layer controls to add aerials or other layers if they're offered.

NYS Tax Parcels Public layer in ArcGIS Map Viewer (13 entries, e.g. Greene County, Hamilton County, Lewis County)

  1. From the county's Platbookmapper page, open the NYS Tax Parcels Public layer in ArcGIS Map Viewer link. It opens in a new tab.
  2. Search for an address or parcel number if the viewer has a search box, or pan and zoom to the property.
  3. Click a parcel to read the attributes the statewide layer carries. Field names vary from county to county.
  4. Statewide layers are compiled copies, so confirm ownership, tax and deed details with the county's own assessor or recorder.

ArcGIS Web AppBuilder (7 entries, e.g. Albany County, Chautauqua County, Chemung County)

  1. Click the official map link on the county's page and wait for the Web AppBuilder viewer to load. Some counties show a terms screen first.
  2. Search by street address, owner or parcel ID if the search box offers those options.
  3. Click a lot on the map to read its attributes.
  4. Turn on aerial imagery from the basemap tool and use the layer list to add things like zoning or flood zones when they're published.

Before you rely on what you find

Online parcel lines are drawn for tax mapping, not surveys, so they can sit a few feet off the real boundary. For anything legal, such as a fence, a sale or a dispute, use the recorded deed and a licensed surveyor. To check flood zones, soils or wetlands for a spot you found, open it on the Platbookmapper Land Map, which pulls FEMA, USDA and U.S. Fish & Wildlife layers.
