Septic systems in North Carolina are regulated by the state and permitted by the county health department, which in Cabarrus County is the Cabarrus Health Alliance rather than a city office. Its Environmental Health section issues the permits, keeps the file on each system, and sends the inspector when a repair is done. This page sets out what is in that file, what a buyer's inspection checks, and which jobs need a permit before the first shovel.
What the county file holds
For a system installed since the county began keeping records, the file typically contains an improvement permit, which says the lot can take a system and where; a construction authorization, which says what was to be built; an as-built sketch showing the tank and the field lines against the house; and an operation permit stating the number of bedrooms the system was sized for. Older systems may have nothing on file, which is worth knowing before an offer.
The bedroom count is the number that matters at sale. A house listed with more bedrooms than the permit allows is a finding on the inspection and, for a lender, a question.
What a real-estate inspection covers
North Carolina does not require an inspection at sale, and lenders vary. A proper inspection opens the tank and checks the levels, baffles and filter; runs water into the system to see whether the field accepts it; walks the field for wet spots and smell; and, where the load test raises a question, cameras the lines. It ends with a written report and photos. A pumping receipt is not an inspection.
- Ask the seller for the county file and the last pumping receipt before booking
- Book the inspection early in due diligence, not the week of closing
- Do not pump the tank before the inspection unless the inspector asks
- Have the report sent to your attorney or agent as well as yourself
Which jobs need a permit
Pumping, filter cleaning, and adding risers and lids to an existing tank need no permit. Replacing a tank, repairing or replacing a drain field, adding a pump, or expanding a system for more bedrooms needs a repair or expansion permit from the county, issued after a site visit. The contractor applies, the county inspects the site and the finished work, and the as-built is updated. A repair done without a permit is a problem at the next sale.
Wells, setbacks and the lot
Where a house is on a private well, North Carolina's onsite wastewater rules set minimum distances between the well and the septic field, and the county checks the distance before permitting any repair. Tighter lots inside the county's newer subdivisions may not have room for a conventional replacement field, in which case the permit can call for a pump to a better area of the lot or a pretreatment unit. The county's Environmental Health office answers these questions by address, and its pages are linked under Local resources on the home page.
Questions we get about this
Can I get the county file myself?
Yes. The Cabarrus Health Alliance Environmental Health office provides septic records by address; ask for the as-built and the operation permit. The crew pulls it as part of an inspection, but there is nothing stopping a buyer from asking first.
Does a repair permit take long?
The county schedules a site visit after the application. Plan on two to four weeks from first call to finished repair, longer if a pretreatment unit has to be ordered.
