To find the location of a parcel, go to the Town of Plainfield's Beacon GIS website and enter the address of the property or the Parcel or Tax ID number in the search bar on the top right of the screen. This will zoom in on your parcel/address. To view the zoning, under "Layers" in the left menu, expand "Planning" and check the box for "Zoning". Your parcel will be colored and show up with a label stating your zoning district.
If you do not see a zoning layer on your parcel/address, then you are not within the Plainfield town limits.
