A site survey — walking and mapping your property’s terrain, sun exposure, water sources, and soil before you build anything — is the step most new off-grid landowners skip, and the one that causes the most expensive mistakes down the line.
What a Site Survey Actually Covers
At minimum: confirming your property boundaries and any easements, mapping sun exposure across different areas and times of day, identifying water sources and drainage patterns, and noting slope and soil type where you plan to build. A formal licensed survey establishes legal boundaries; a practical homestead site walk covers the rest, and you generally need both.
Why Boundaries Matter More Than You’d Think
Rural property lines are often poorly marked, especially on land that’s changed hands multiple times or was subdivided decades ago. Building a structure, well, or septic system too close to a boundary can create real legal problems later — a licensed survey before construction is cheap insurance against that.
Sun and Solar Exposure
Walk the property at different times of day and different seasons if you can, since tree shading and terrain shadows shift significantly between summer and winter sun angles. This directly affects where solar panels will actually perform, not just where they’d fit.
Water and Drainage
Note where water naturally flows and pools after rain — this affects everything from septic placement to whether a low spot floods seasonally. It also helps you spot where rainwater catchment or a pond might work well versus where building would be a mistake.
Putting It to Use
Once you’ve surveyed the land, our land suitability calculator can help you score different building sites on your property against each other, and a percolation test will tell you whether your chosen septic location will actually work.
