Publication Date: April 2025. The Westchester County Parcels layer contains 2023- 2024 parcel data only for the County which gave NYS ITS Geospatial Services permission to share this data with the public. No attempt was made to edge-match parcels along adjacent counties. County attribute values were populated using 2024 Assessment Roll tabular data Geospatial Services obtained from the NYS Department of Tax and Finance’s Office of Real Property Tax Services (ORPTS).Tabular assessment data was joined to the county provided parcel geometry using the SWIS & SBL or SWIS & PRINT KEY unique identifier for each parcel. Detailed information about assessment attributes can be found in the ORPTS Assessor’s Manuals available here: https://www.tax.ny.gov/research/property/assess/manuals/assersmanual.htm.

This layer identifies corporate boundaries for all 45 municipal jurisdictions in Westchester County. Coverage originally obtained from New York State Office for Real Property Services (ORPS), and has been substantially modified to better align with current municipal tax parcel boundaries (WCparcels) based on a compilation of 2012 municipal tax parcel datasets. As all of Westchester's town's and cities compile their tax parcel databases independent of one another, there are situations were the tax parcels do not line up at the municipal borders, often resulting in gaps or overlaps of tax parcels at the border areas. This update sought to re-align boundaries to best follow the municipal boundaries as defined by the tax parcels, and often involved making the best possible spatial compromise where there were gaps or overlaps in tax map jurisdictions. It also reflects the 2011 municipal boundary change that resluted from the annexation of a tax parcel from the Town of Mount Pleasant to the Town of New Castle.

Publication Date: April 2025. This polygon layer is updated annually.

This layer contains 2024 parcel data only for NY State counties which gave NYS ITs Geospatatial Services permission to share this data with the public. Work to obtain parcel data from additional counties, as well as permission to share the data, is ongoing. To date, 36 counties have provided the Geospatial Services permission to share their parcel data with the public. Parcel data for counties which do not allow the Geospatial Services to redistribute their data must be obtained directly from those counties. Geospatial Services' goal is to eventually include parcel data for all counties in New York State.

Parcel geometry was incorporated as received from County Real Property Departments. No attempt was made to edge-match parcels along adjacent counties. County attribute values were populated using 2024 Assessment Roll tabular data Geospatial Services obtained from the NYS Department of Tax and Finance’s Office of Real Property Tax Services (ORPTS). Tabular assessment data was joined to the county provided parcel geometry using the SWIS & SBL or SWIS & PRINT KEY unique identifier for each parcel.

Properties classified as Farms derived from the Westchester County Agricultural District established in 2000. The information used to compile the data came from a variety of sources including aerial photography, digital tax parcel data, local recreation, land use, and master plan maps. Other sources included municipal planning departments and consultants, conservation committees, and the Westchester Land Trust.
