Septic Inspection for a Home Sale in Lumberton, NC

Is an inspection required to sell?

We found no North Carolina statute or rule that requires a septic inspection to sell a house; buyers arrange one during due diligence when they want it. State certification law defines an inspection in terms of who asks for it: one "requested by a lending institution, realtor, prospective homebuyer, or other impacted party" as a condition of a sale, refinancing or transfer. NC REALTORS' buyer advisory recommends that "the system should be inspected by a licensed on-site wastewater inspector hired by you," and notes that the length of the due diligence period and its fee are entirely negotiable between buyer and seller. If a lender or buyer asks for an inspection, plan for it early.

Who may do it

The North Carolina On-Site Wastewater Contractors and Inspectors Certification Board certifies a "Point of Sale Inspector." To qualify, an applicant must have held Grade Level IV installer, AOWE or subsurface operator certification for two years, or complete approved Grade IV education, and every applicant must pass an exam. Certified inspectors may inspect all on-site systems covered by the board's rules. NC REALTORS adds a point worth knowing: "Real estate agents are not licensed to do plumbing or septic inspections." Look an inspector up on the board's Certification List, and see who repairs septic systems for the other credentials.

What a certified inspection covers

The board's standards of practice for inspectors, readopted effective November 1, 2025 in 21 NCAC 39 Section .1000, list what a point-of-sale inspection looks at. Among the items:

What it won't tell you

The same standards set limits. An inspector isn't required to report how long the system will last, what a repair would cost, or the property's market value, or to predict the future condition of components, including failure. The inspector also isn't required to evaluate the soil beyond saturation or ponding, or to perform a hydraulic load test. On Robeson County's wetter soils, that means a report can tell you water is ponding over the lines, but not whether the ground could support a new field. That takes a soil evaluation from the health department or a private evaluator.

The report

• Written, and delivered within 10 business days of the inspection.
• Includes the inspector's name, license number and signature.
• States whether a condition calls for repair, observation, or further evaluation.
• The inspector keeps records for seven years.

Pull the county's records too

NC REALTORS' advisory tells buyers to check with the county health department for information on a particular property. In Robeson County, the department's Environmental Health Forms page lists a "Permit Inquiry Form for Real Estate Transactions." Call the on-site line, (910) 272-6560, to make sure you have the right form and to ask how long a reply takes. Separately, the county's posted fee schedule lists an on-site wastewater existing system evaluation at $200, a county visit distinct from a private inspection. Ask whether it fits your situation.

Sellers: the disclosure statement

North Carolina's residential disclosure statement, required by rule 21 NCAC 58A .0114, asks about the sewage disposal system and, for septic, the number of bedrooms allowed under the permit. It also asks about problems with plumbing, water supply, sewer or septic. A seller may choose to state that they make no representations, under G.S. 47E-4. The statement is due no later than when the buyer makes an offer. For a buyer, the bedroom count on the permit is worth comparing with the listing, and a mismatch is a question for the health department before closing. Under Session Law 2023-77, the health department, a certified inspector or an AOWE can verify that an addition won't harm the system.

When the report finds a problem

NC REALTORS notes that repair work goes ahead "after a permit for the repairs is issued by the county health department." In Robeson County, a repair starts with the Repair Application and a repair evaluation, posted at $100. Since a permitted repair waits on the county, it helps to get a contractor out early when a closing date is set. If the problem is in the trenches, see drain field repair; if it's the tank or the whole system, see septic system replacement.

What an inspection costs

National figures from HomeServe's July 2024 guide: $150 to $450 for a maintenance inspection, about $300 to $650 for a comprehensive one, and an average of $290, citing HomeGuide. A camera inspection of the lines runs $125 to $500 in the same guide. Pumping, which a complete inspection calls for, averages $420 nationally in This Old House's May 2026 guide. These aren't Robeson County quotes; the inspector's written price is what counts.

Who this page isn't for

If the house is on town sewer, there's no septic system to inspect. If you aren't buying or selling and simply want the system checked, NCDHHS suggests having it inspected every three years by a qualified professional; septic pumping covers routine care.

Inspection questions

Can a home inspector do the septic inspection?

North Carolina certifies point-of-sale septic inspectors through the on-site board. Ask any inspector for their board certification and check it on the Certification List. Real estate agents, per NC REALTORS, aren't licensed to do septic inspections.

Does the tank have to be pumped?

For a complete inspection, yes, according to the board's standards. The client can decline pumping, but signs a statement saying so.

Will the report say pass or fail?

The standards describe a report that says whether a condition needs repair, observation or further evaluation. Ask the inspector how their report presents findings before you hire them.

How do I find out what the county has on file?

Ask the Robeson County Health Department about its Permit Inquiry Form for Real Estate Transactions, at (910) 272-6560 or 910-671-3200.

How the referral works

If an inspection turned up a problem, or you'd like the system looked at before listing, your request is passed to a single independent septic contractor serving Robeson County, who prices the work. You pay nothing for the referral. Contractors are responsible for holding the certification each job requires.
