What to check before buying land in Caswell County

Ordered by what Caswell County's numbers point to. Every parcel differs, so treat this as where to look first.

  1. 1.Budget for a perc test and maybe an engineered septic

    USDA rates 78% of Caswell County's mapped soils "very limited" for conventional septic absorption fields and 0% "not limited".

    Without city sewer you need a septic permit from the county or state health department. Make the offer contingent on a passing soil or perc test; mound and aerobic systems can cost several times a conventional one.

    Guide: Perc tests and septic systems

  2. 2.Check slope where you'd build and where the driveway goes

    30% of Caswell County's mapped soils have an average slope over 15% (USDA SSURGO).

    Steep ground means grading, retaining walls, longer driveways and erosion control. Compare the slope at the house site and along the access route, not just the parcel average.

    Guide: Terrain and slope

  3. 3.Confirm legal road access and power

    The 2020 Census classified 100% of Caswell County's land area as rural.

    Rural tracts are often sold without recorded access or a power line nearby. Get the title company to confirm a recorded easement or public road frontage, and ask the electric co-op what a line extension costs.

  4. 4.Check the soils if you plan to farm, graze or garden

    Farm real estate in Caswell County averaged $4,006 an acre including buildings in the 2022 Census of Agriculture, and 50% of its mapped soils are prime or of statewide importance.

    Compare the asking price with recent sales of similar tracts, not the county average, which mixes cropland, pasture, timber and homesites. If an ag tax valuation applies, ask what the rollback taxes would be if you change the use.

  5. 5.Confirm the flood zone at your exact spot

    4% of the county's area is in the 1%-annual-chance (100-year) floodplain FEMA's National Risk Index uses for inland flooding; 5.5% of its mapped soils flood occasionally or frequently.

    Even where little of the county floods, creeks and low spots do. Check the FEMA zone at the building site and the driveway route.

    Guide: Flood zones before buying land

  6. 6.Find out where the water comes from

    At least half of Caswell County was in severe drought (D2) or worse in 18% of the 262 weekly U.S. Drought Monitor maps from 2021 to 2026.

    Ask whether the land has a public water connection, an existing well (and its log and yield), or neighbors' well depths from the state well database. For a new well, check permits and typical depth with the state agency first.

Questions about buying land in Caswell County

How much of Caswell County, NC is in a flood zone?

About 4% of Caswell County's area is in the 1%-annual-chance (100-year) floodplain used by FEMA's National Risk Index (December 2025), 14th lowest of 100 counties in North Carolina. Whether a given parcel is in a flood zone depends on its exact location, so check the FEMA map at your pin.

How much does land cost per acre in Caswell County?

The 2022 Census of Agriculture put the average value of farm land and buildings in Caswell County at $4,006 an acre, 15th lowest of 100 counties in North Carolina (the median North Carolina county was $5,848). It's a self-reported average across farms, so small homesites and recreational tracts often sell for more per acre.

Will a septic system work on land in Caswell County?

Often, but test first. USDA soil surveys rate 78% of Caswell County's mapped soils very limited for conventional septic absorption fields, usually because of wetness, slow permeability, shallow rock or flooding. A perc or soil test on the parcel decides what system the health department will permit.

Is there good farmland in Caswell County?

29% of Caswell County's mapped soils are prime farmland, 5.2% are prime only if drained, irrigated or protected from flooding, and 21% are farmland of statewide importance (USDA SSURGO). The 2022 Census of Agriculture counted 412 farms averaging 205 acres.

How often is Caswell County in drought?

Since 2021, at least half of the county was in severe drought or worse in 18% of weekly U.S. Drought Monitor maps, and in extreme drought in 11%. On 2026-10-27, 100% of the county was in moderate drought or worse.

What these numbers can't tell you

  • County shares describe Caswell County as a whole; a parcel can be entirely in or out of a flood zone, wetland or poor soil.
  • It doesn't look at the whole parcel, its boundaries, title, easements, zoning or permits.
  • It isn't a survey, appraisal, elevation certificate, soil or perc test, or Phase I environmental site assessment.
  • It can't see local distribution power lines, driveways, legal access, wells or mineral rights.
  • Maps lag behind the ground, and distances are straight-line, not driving distance.
