How Does the Septic Permit Process Work in North Carolina?
In North Carolina, a new septic system is permitted through the county health department. You apply, and a county specialist evaluates the soil. A suitable site gets an Improvement Permit, then a Construction Authorization. After the system is installed and passes inspection, the county issues an Operation Permit.
The steps come from the state’s septic rules, 15A NCAC 18E, so every county follows them. In Alamance County, home to Burlington, the first two permits for a three-bedroom conventional system cost $565 in county fees. If you are planning a new septic system in Burlington, the permits come before the install.
What are the steps in the septic permit process?
| Step | What happens | What you get |
|---|---|---|
| 1. Application | You file the form, a site plan or plat, and the fee | A spot on the schedule |
| 2. Site and soil evaluation | A specialist checks the soil and the lot | A written ruling |
| 3. Improvement Permit | The county approves the site and a repair area | A map of where the system goes |
| 4. Construction Authorization | The county sets the system type and layout | Clearance to install |
| 5. Installation and final inspection | The system goes in and is inspected before cover | A pass, or a list of fixes |
| 6. Operation Permit | The county approves the finished system | The right to use it and move in |
What do you need to bring when you apply?
In Alamance County, you apply to Environmental Health at the county health department in Burlington. The form asks how many bedrooms the house will have and where its water will come from. It also asks for the building’s largest length and width. Bring a photo ID too.
You also attach a site plan or a plat. A site plan need not be drawn to scale, and it earns a permit good for five years. A plat earns a permit with no expiration date. The site plan shows:
- the property lines and dimensions
- the house spot and size, with distances to the road and side lines
- the driveway and any planned garage, shop or pool
- wells and septic systems on your lot or within 100 feet of your lines
- easements, rights of way and wetlands
Show the well, or the spot for a new one. State rules keep a septic system at least 50 feet from a home’s private well. Buying the lot? Alamance County accepts a real estate contract to name you the owner’s representative.
How do you get the lot ready for the evaluation?
Mark the property corners and lines. Stake the house, the driveway and any garage, shed or pool. The area to be evaluated must be clear of thick vegetation and debris. If it is not, the specialist stops and asks you to open it up.
On a wooded lot, land clearing around the house site and the septic area comes first. Alamance County’s form also says to call 811 to mark utilities before the county comes out. If the lines or the house are not marked, the county charges a $95 revisit fee. Your application then goes back in line by the date that fee is paid.
What happens at the site and soil evaluation?
A county environmental health specialist bores into the soil with an auger, in the system area and the repair area. You may instead hire a licensed soil scientist, whose evaluation goes in with your application. The rules call for a look at least 48 inches down, or to a limiting condition such as wet soil. The specialist records:
- slope and landscape position
- soil texture, structure and color, including signs of wetness
- depth to rock or saprolite
- restrictive layers in the soil
- room for the system plus a repair area
The county sometimes asks the owner for pits, such as to look at saprolite. The pits need dug steps or a ramp so the specialist can climb in and out. Alamance County notes that pits are generally dug with a backhoe, a job for an excavation contractor.
You get the result in writing. An Improvement Permit shows where the system must go, plus a repair area for a future drain field. Keep buildings, pools, driveways and utility lines off both. A denial lists the reasons and your right to appeal.
How long does each step take?
Alamance County lists no set wait for the evaluation, so ask the office. State law gives counties a yardstick of 60 days to act on a complete application for a conventional system. A county that repeatedly misses it can lose state public health funding.
Other clocks are fixed:
- With a licensed soil scientist’s evaluation attached, the county’s completeness review comes within five business days.
- An application left waiting on the owner expires after 12 months.
- The Construction Authorization can come with the Improvement Permit if no conditions must be met first.
Once the site is ready, the install itself is often a one-day job.

How do the install and final inspection work?
With the Construction Authorization issued, you can apply for the building permit. State law holds building, electrical, plumbing and heating permits for a new house until then.
The system is built to the layout on the Construction Authorization. The county inspects it before any soil covers it, and anything that misses the rules gets fixed first. Once it passes, the county issues the Operation Permit. No one may move in before that.
What if you are replacing a failed septic system?
A failed system needs a permit too, and the application comes before any repair work. In Alamance County, the repair permit costs $0. The county’s repair application asks about your water use and the problem. A specialist visits to find the cause, then issues the repair permit.
The county’s own page warns that repairing a system without that permit is illegal. The new system then gets the same inspection before it is covered.
Is the process the same in other counties?
Yes. The steps come from state law, so they hold in Guilford, Durham, Orange, Rockingham, Randolph, Chatham and Caswell counties. Each county’s health department sets its own forms and fees. A local board of health may also adopt stricter rules with state approval. Orange County, for one, publishes its own wastewater rules.
Towns can add a step too. In Summerfield, the town’s Development Clearance Certificate comes before you apply to Guilford County for a soil evaluation. If the house and the system sit in different counties, the county that taxes the house handles the permits.
