Important Note:
It's important to note that this zoning code information represents a compilation of local zoning districts and is based on zoning information compiled and digitized from each of Westchester's 43 municipalities between 2011 and 2024. It is important to note that it is not an officially adopted map of local zoning, but rather a depiction - or "snapshot" - of local zoning at the time of compilation. As such, this data layer is intended to be used for general reference purposes only. Since local zoning is constantly subject to change, inquiries regarding current status of local zoning districts, zoning designations of specific parcels, and exact use and bulk requirements should be verified at the local level by contacting the local planning or municipal clerk’s office. Selected updates were completed for this data layer in 2015 and 2016 for the municipalities of Rye City, Town of North Castle, Village of Mamaroneck and Port Chester. Updates for the City of Mount Vernon were completed in April 2021. In 2022/2023 Westchester County conducted an outreach project to obtain updated data. The following municipalities were updated during this time: Ardsley, Dobbs Ferry, Greenburgh, Lewisboro, Mount Pleasant, North Salem, New Castle, Village of Ossining, and Peekskill. Updates for Briarcliff Manor and Buchanan were made in 2024. Buchanan has one overlay district which is an exception because no other polygons should be overlapping.
