A new property-search service called Unfenced has launched with a narrow aim: finding land for sale that directly borders public land in the United States. The project says it measured 13,626 properties against official boundary data after examining 695,439 active listings across 49 regions.
The service is intended for buyers seeking direct access to protected landscapes rather than simply a home near open space. Its central distinction is geometric. Unfenced says every result is calculated from parcel boundaries, allowing it to identify land that physically touches a public parcel instead of relying on estate-agent descriptions or broad distance searches.
For its public-land layer, the project uses the US Geological Survey's Protected Areas Database of the United States, commonly known as PAD-US. That national inventory combines boundaries and management information for protected areas held by public agencies and some private organisations. Unfenced compares those mapped areas with the boundaries attached to current sale listings.
The resulting catalogue offers a data-driven starting point, not a guarantee that any parcel has a usable entrance to the adjoining land. A shared mapped boundary can be separated by terrain, fencing, water or other physical constraints. Legal access can also depend on easements, local restrictions and the rules imposed by whichever agency manages the neighbouring property. Prospective buyers would still need to examine title records, surveys and on-the-ground conditions.
The project also depends on the accuracy and freshness of two changing datasets. Property listings can be withdrawn, repriced or sold, while parcel maps may contain incomplete or outdated geometry. Protected-land boundaries and management classifications can change as well. Unfenced's published counts therefore represent a snapshot of the inventory it processed rather than a permanent census of available land.
Even with those limitations, the approach addresses a weakness in ordinary real-estate search. Listings frequently use phrases such as “near national forest” or “close to public land,” but those descriptions do not establish a direct border. Measuring parcel polygons can narrow a large national inventory to properties worth investigating in more detail.
Unfenced has not presented the dataset as an appraisal, survey or legal opinion. Its value lies in discovery: combining active listings with a recognised public-land database and making a specific spatial relationship searchable. Buyers considering a result would still need professional verification of parcel lines, permitted uses, access rights and the status of the adjacent protected area before completing a purchase.
The initial scale suggests the filter can reduce a very large national pool to a smaller set with the requested boundary relationship. It does not determine whether a property is affordable, buildable or suitable for a buyer. Those questions remain outside the stated measurement and require the same due diligence as any land transaction.
