How Do I Know If Raw Land Is Buildable?

July 30, 2026 ONNIT Realty Group Updated July 30, 2026

Determining whether raw land is buildable requires checking several independent factors, and skipping any one of them can turn what looks like a straightforward purchase into a costly problem. Start with zoning — confirm the parcel’s current zoning allows your intended use, and check for any overlay districts (like watershed protection or airport noise zones) that could add restrictions beyond the base zoning.

Soil and perc testing matters enormously for any property that will rely on a septic system rather than public sewer, which is common for rural or semi-rural land in Cumberland County. A percolation test determines whether the soil can adequately absorb and treat wastewater, and land that fails perc testing may not be buildable at all without expensive engineered septic solutions, or may not be buildable for a septic system at all.

Utility access is another key factor — check the distance to the nearest power, water, and sewer connections, since extending utilities to a remote parcel can add substantial unplanned cost to a project. Flood zone status matters too; FEMA flood maps will show whether any portion of the parcel falls within a flood zone, which affects buildability, insurance costs, and construction requirements if building is possible at all.

Finally, confirm legal access to the property — a landlocked parcel without a recorded easement to a public road isn’t buildable regardless of how favorable every other factor looks, and access disputes can be some of the most difficult and expensive issues to resolve after purchase. A land-specific due diligence period, including a survey, perc test, and title review before closing, is the standard way to verify all of these factors rather than assuming a piece of land is buildable based on appearance alone.
