FAQ

What is a perc test on vacant land?

A perc test (percolation test) tells you whether the soil will absorb a septic system. If the land is not on a public sewer line — and most SC vacant land is not — you need a passing perc test before you can build anything that uses water.

1. What is a perc test?

   A perc test (percolation test) measures how fast water drains through the soil. The county environmental health office digs a few test holes, fills them with water, and times the drainage. If the soil drains too slow (clay) or too fast (sand), it cannot support a conventional septic system and the parcel may be unbuildable for residential use.

2. Do I need a perc test before buying vacant land in SC?

   If you plan to build anything that uses water (a house, cabin, RV pad with septic), yes — and during the inspection period of your purchase contract. If the land is recreational only (hunting, timber, parking), you may not need one, but a passing perc test substantially raises the resale value.

3. How much does a perc test cost in SC?

   In South Carolina, perc tests are run by the county DHEC (Department of Health and Environmental Control) office. The test fee is typically $50-200, plus you pay a contractor to dig the test holes ($150-400). Total: usually $300-600. Some counties have wait times of 2-6 weeks.

4. What does "perc passed" mean on a SC land listing?

   It means the seller has a recent passing perc test on file from the county DHEC office. The test is parcel-specific and typically valid for 5 years. A passed perc is one of the strongest signals a vacant land parcel is buildable.
