A practical guide to evaluating whether a piece of land is suitable for building, including tests, inspections, and data sources.
According to LandSquatch data covering 198,170+ properties across Georgia and Florida, understanding how to assess land buildability is essential for making informed land investment decisions.
Start with zoning verification — contact the county planning department to confirm residential construction is allowed. Then check: soil suitability (perc test for septic), flood zone status (FEMA maps), slope (under 15% is ideal for standard construction), road access, and utility availability. LandSquatch's Buildability Score automates these checks across 198,170+ properties.
Essential tests include: percolation (perc) test for septic feasibility ($300-$500), soil boring test for foundation design ($500-$1,000), and a topographic survey ($500-$1,500). If you suspect environmental issues, add a Phase I Environmental Site Assessment ($1,500-$3,000). These tests can save you from buying unbuildable land.
Common deal-killers include: failed perc test with no municipal sewer available, flood zone AE designation (requires expensive elevation), slopes over 30%, protected wetlands covering the buildable area, no legal road access, restrictive covenants prohibiting construction, and environmental contamination. LandSquatch flags many of these issues in the Land DNA report.
