About the official source
This map is published by or for Plymouth County itself, so it reflects the local parcel layer rather than a third-party copy. When we tested the link in October 2026 it opened with no login and no fee.
Searching for a parcel, step by step
- Open the link to the Beacon site from Schneider Geospatial. If a terms or disclaimer window appears, agree to it to continue.
- Use the search bar to look up a street address, an owner's name or a parcel ID. Beacon sites usually also have a dedicated property search page.
- Click a lot on the map and then open its report for assessment and property details.
- Use the layer and basemap controls to add aerial photos or other layers the county publishes.
If an address search comes up empty, try the parcel number from a tax bill or deed instead, or click the lot on the map.

Maps vs. surveys
Keep in mind that a GIS parcel layer is a tax map, not a survey. For exact boundaries, look at the recorded deed and plat or hire a licensed land surveyor.
