Can a buyer back out if the perc test fails?
Only if the purchase contract lets the buyer. A contingency tied to a soil evaluation or perc test, with its own deadline and notice terms, is what opens the exit; Virginia's septic permit rules do not create one. A failed perc test may not settle the site either, because the regulation treats it as only one of many criteria for soil suitability.
The soil report is bad news, and the contingency clause says what happens next
Picture the day the soil evaluator's findings reach a seller whose land is already under contract, and they are not what the buyer hoped for. Before anyone opens the Code of Virginia, both sides open the same document, the purchase contract, and look for the clause that makes the sale depend on the soil work.
That clause is a contingency, with its own deadlines and notice terms, and it answers the questions that matter that day. Is there one at all? What result does it name: a passing perc test, a written soil evaluation, a certification letter from the health department, or an issued septic permit? By what date does the buyer have to act, and in what form does notice go to the seller? A contract may tie that date to a due diligence period.
The septic regulations govern the soil and the permit, not the sale.
A perc test is one piece of evidence, and the soil evaluation carries the rest
Before either side treats the result as final, it helps to know what was actually tested. A perc test is not the whole soil evaluation, and Virginia's regulation does not treat it that way.
The regulation treats a soil evaluation as a systematic look at the whole site and its soil profile, horizon by horizon. A percolation test may be required before a permit is issued, and the health department may require one when it questions the estimated percolation rate, but the regulation is plain about how much a test weighs.
Percolation tests shall be analyzed as only one of many criteria in determining soil suitability for absorption of treated sewage.

So the word failed deserves a second look before anyone relies on it. A rate from test holes, an evaluator's written findings and a health department decision are three different papers. Which of those papers the contingency names is part of what the attorney reads. How perc tests work, and why the soil evaluation comes before them, walks the whole sequence.
Whether the buyer can leave and whether the ground can work are separate questions
A buyer with the right to leave does not have to use it, and a buyer who stays is asking a narrower question: can this ground still carry a house on terms that work?
A denial is not always the end of the permit file: the Review Board that hears appeals of septic permit denials may recommend alternative solutions and send the case back to VDH, and the regulations provide for conditional construction permits, and Virginia law recognizes an alternative septic system, which it defines as treatment works that are not a conventional onsite system and do not result in a point source discharge. Whether you can build on land that failed a perc test takes those paths one at a time.
With that in view, and depending on its terms, a contract under a soil contingency can leave the parties four moves:
- The buyer ends the contract under the contingency, if the clause allows it and notice goes out in time.
- Both sides extend the deadline in a signed amendment, so a licensed onsite soil evaluator, or a professional engineer working with one, can look at other options for the site.
- Both sides rewrite the terms around a different system or a conditional permit, once the health department has said what the site can carry.
- The buyer waives the contingency, if the contract permits it, and goes forward knowing the result.
One detail matters when land is about to change hands: a variance from the sewage regulations, when the Commissioner grants one, is nontransferable. Who arranged and signed for the soil work also shapes the next step, and who orders the perc test, buyer or seller, covers that as a contract term.
If the buyer leaves, the soil file stays with the tract
A seller whose buyer walks away still owns what the soil work produced, and some of it can outlast the contract.
If the health department has issued a certification letter recognizing that the site conditions are appropriate for an onsite sewage system, that letter transfers with the title when the land is sold. A report that went the other way is information too, and what a seller does with it before the land goes back on the market is a question for the seller's attorney.
How the ground, soil included, is read before a tract is priced is set out on selling land in Southwest Virginia.
Selling land with a soil evaluation contingency still open?
Send the county, the acreage and where the soil work stands. Lowell will talk through the ground and the listing; the contract terms stay with your attorney. No cost, no obligation.
Got it. Thank you.

Questions this raises
What if the soil work was only a percolation test and not a full soil evaluation?
Then the result covers less than the regulation weighs. A Virginia soil evaluation looks at the whole site and its soil profile, and the regulation says percolation tests are analyzed as only one of many criteria in determining soil suitability. Whether a perc result alone meets the condition a contingency names is a reading of that contract for a Virginia real estate attorney.
Does a denied septic permit come with a written reason?
Yes. When a construction permit is denied, the owner is notified in writing of the basis for the denial, and the notice also states that the owner has the right to appeal. The applicant is advised in writing of the administrative remedies available, and the Sewage Handling and Disposal Appeals Review Board hears appeals of permit denials.
