Building permits in North Carolina: what needs one and how it works
In North Carolina, you need a building permit before you build, alter, repair, move, or demolish a building, or install its plumbing, heating, cooling, or electrical systems. State law lists the exemptions. The local inspections department issues the permit, inspects the work, and closes it with a certificate of occupancy.
Start an infill lot searchQuick summary: This guide explains what needs a building permit in North Carolina, the exemptions state law lists, how plan review and inspections work, and when a permit expires. It is for owners who plan to build on a lot, infill builders, and buyers who want to know what a permit record means. The key takeaway: off public sewer, the septic construction authorization comes before the building permit, and the permit ends with a certificate of occupancy.
What a building permit is
A building permit is the written approval to start construction work that the North Carolina State Building Code covers. Under N.C. Gen. Stat. § 160D-1110, the permit must be in writing. It must state that the work will comply with the building code and all other applicable state and local laws.
The permit is one approval in a chain. Zoning, wastewater, and erosion control approvals often come before it, and the certificate of occupancy comes after it. For the full order on a lot, see Building a house on land you own: the order of approvals.
What needs a building permit
State law requires a permit before you start or continue any of these activities:
- Buildings. Construction, reconstruction, alteration, repair, movement to another site, removal, or demolition of any building or structure.
- Plumbing. Installation, extension, or general repair of a plumbing system.
- Heating and cooling. Installation, extension, alteration, or general repair of a heating or cooling system.
- Electrical. Installation, extension, alteration, or general repair of electrical wiring, devices, appliances, or equipment.
The list is in § 160D-1110(a). It covers demolition, so a teardown on an infill lot starts with a permit too. See Demolition permit and asbestos survey before a teardown.
What does not need a permit
The statute exempts some work, and the main exemption turns on cost. Under § 160D-1110(c), no permit is required for construction, installation, repair, replacement, or alteration costing 40,000 dollars or less in a single-family residence, farm building, or commercial building. The work must meet the current building code.
The cost exemption does not apply when the work involves any of these:
- Adding, repairing, or replacing load-bearing structures. Replacing windows, doors, siding, and porch or deck pickets, railings, treads, and decking stays exempt.
- Adding plumbing or changing its design.
- Adding, replacing, or changing the design of heating, air-conditioning, or electrical wiring, other than like-kind replacement of devices and lighting fixtures.
- Materials the building code does not permit.
- Adding roofing, other than a replacement.
- Any change the North Carolina Fire Code covers.
Subsection (a) also lists narrow trade exemptions in one- and two-family dwellings. Examples are a like-for-like water heater replacement by a licensed contractor and the replacement of light fixtures, receptacles, and switches with matching ratings. Ask the inspections department before you rely on an exemption, because a mistake makes the work a violation.
Watch for: The cost exemption is about repairs and small work on an existing building. A new house, an addition, or any new load-bearing structure needs a permit at any cost.
The septic gate comes first
On a lot without public sewer, no building permit can issue until the septic construction authorization issues. Under N.C. Gen. Stat. § 130A-338, no electrical, plumbing, heating, air-conditioning, or other construction permit issues for a residence until the local health department issues a construction authorization. On a private path, the gate opens when the health department decides that a notice of intent to construct is complete. See Septic permits in North Carolina: the improvement permit, the construction authorization, and the operation permit.
A second gate applies to land disturbance. Under § 160D-1110(e), no building permit issues for land-disturbing activity that state law covers until an erosion and sedimentation control plan is approved for the site.
Plans, plan review, and who may build
The permit application carries plans, and the inspections department may review them. For a house under the North Carolina Residential Code, § 160D-1110(b) does not require a local government to review the plans. If it does review them, the initial review must be done within 15 business days of submission. Past 20 business days, the local government refunds 10 percent of the permit application fee for each late business day, for up to 10 business days.
The statute also sets these plan rules:
- Author. Plans must show the name and address of their author.
- Seal. A local government may not require an engineer’s or architect’s seal on plans for a one- or two-family dwelling unless the building code requires it.
- Licensed contractors. Work that state law reserves for a licensed specialty contractor gets a permit only when that contractor does the work.
- Lien agent. For work costing 40,000 dollars or more, the permit shows the owner’s lien agent, with exceptions for an owner-occupied house and its accessory buildings.
An owner may build a house for the owner’s own family without a general contractor license. Under N.C. Gen. Stat. § 87-1(b)(2), the house must be intended solely for the owner’s family. The statute presumes otherwise if the family does not occupy it for at least 12 months after completion. Under § 87-14, the owner signs a verified affidavit and agrees to be present for every required inspection, unless a licensed architect sealed the plans.
Inspections during the work
Inspectors make as many inspections as they need to confirm that the work follows the law and the permit. That rule is in § 160D-1113. Inspectors may enter the site at reasonable hours with proper credentials. For an owner-builder under the § 87-1(b)(2) exemption, no inspection takes place without the owner present, unless a licensed architect drew and sealed the plans.
A typical house follows a fixed sequence. The Brunswick County residential inspection guide lists footing, under-slab, foundation, rough-in, framing, and insulation inspections, then the trade and building finals. A floodplain inspection is added in a mapped flood zone.
The inspector can revoke a permit. Under § 160D-1115, a permit is revoked for a substantial departure from the approved plans, a failure to comply with the law, or a false statement in the application. When the work passes the final inspection, the inspector issues the certificate. See Certificate of occupancy in North Carolina.
Take action: Before you buy a lot for a new house, find out which approvals stand between the lot and a building permit. Start with Can the house you want fit on this lot?
When a building permit expires
A building permit expires six months after it issues if the work has not started, or sooner if a local ordinance sets a shorter time. That rule is in § 160D-1111. After work starts, the permit expires at once if the work stops for 12 months. No work under an expired permit may continue until you get a new permit.
For a buyer, an expired permit on a lot is a question, not an answer. Ask the inspections department what the record shows and what a new permit would require.
Who issues building permits
The local inspections department issues building permits, reviews plans, and makes inspections. Under § 160D-1102, every local government provides inspections through its own department, a joint department, a contract with another local government, or the county. If a local government provides no inspection services, the State Fire Marshal arranges them.
Inside a town, the town or the county may do the work, depending on the arrangement. The zoning approval usually comes from the same jurisdiction’s planning staff. See Zoning permits: the approval before the building permit and A zoning label is only the beginning.

- Off public sewer, the septic construction authorization must issue before the building permit.
- A permit expires six months after issue if work has not started, and at once if work stops for 12 months.
- The local inspections department issues the permit, inspects the work, and closes it with a certificate of occupancy.
Questions
Do I need a permit to build a house on my own land in North Carolina?
Yes. A new house needs a building permit at any cost, and the trade work in it needs permits too. An owner who builds for the owner’s own family may act without a general contractor license, under the affidavit and inspection rules in state law.
How long is a building permit good for in North Carolina?
It expires six months after it issues if work has not started, or sooner if a local ordinance says so. Once work starts, it expires if the work stops for 12 months.
Who issues building permits in a county with no town?
The county inspections department issues them, or another local government that provides inspections under a contract or joint department. If no local government provides the service, the State Fire Marshal arranges it.
Can I get a building permit before the septic permit?
No. State law bars building, electrical, plumbing, and heating permits until the health department issues the construction authorization, or decides that a notice of intent on a private path is complete.
