The City of Wilmington does not issue building permits. New Hanover County Building Safety issues every one inside the city limits — but the city's Zoning Section must approve the application first. Two authorities, one permit, and the city's sign-off is a precondition rather than a parallel track.
Wilmington adds two more layers on top. Local historic districts and historic overlays require a Certificate of Appropriateness for exterior alterations, and the downtown district is far larger than most applicants assume. And because New Hanover is a CAMA county, coastal clearance runs on its own clock beside everything else.
Applies inside Wilmington city limits. New Hanover County issues the building permit; the city controls zoning, entitlements, and Certificates of Appropriateness.
The COA comes before the permit. In a local historic district or historic overlay, a Certificate of Appropriateness is required for exterior alterations, and a building permit does not substitute for one. The 2003 district expansion reaches from Greenfield Lake to MLK Boulevard and the riverfront to 15th Street.
What requires a permit in Wilmington?
A Wilmington building permit is required for the construction of buildings and structures, change of building use, demolition, alterations and remodeling, upfits, expansions, accessory structures, mobile homes, and new construction or relocation inside the city limits. The structure of who does what here is the fact that governs everything else, and it catches people constantly.
Permit required
- New construction and relocation of buildings and structures
- Alterations, remodeling, upfits, and expansions
- Change of building use or occupancy
- Demolition of structures
- Accessory structures and mobile home placement
- Exterior alterations in a local historic district or historic overlay, which need a COA first
- Development inside a CAMA Area of Environmental Concern
- Signs, and use permits under the Land Development Code
Typically exempt
- Nonstructural work costing $40,000 or less in a single-family home, farm building, or commercial building (G.S. 160D-1110(c))
- Replacement windows, doors, exterior siding, and porch/deck pickets, railings, stair treads, and decking
- Like-for-like plumbing swaps that keep size and capacity, and like-kind light fixtures, receptacles, and switches
- Same-spec water heater changeouts installed by a licensed contractor
- Painting, flooring, cabinetry, and other cosmetic work

Wilmington building department: who handles permitting
New Hanover County issues all building permits inside the City of Wilmington. There is no city building permit counter. What the city holds is zoning — and the city's Zoning Section must approve the building permit application before the county will issue it. So a Wilmington project has two authorities and one permit, and the city's approval is a precondition rather than a parallel track.
The city runs its own Development & Permitting Services (DPS) online platform for the records it does control: Zoning Permits, Entitlement Applications, and Certificates of Appropriateness. The building record itself lives in the county's COAST portal. Two platforms, two logins, one project.

Sequence the two authorities deliberately. Zoning approval from the city comes first, then the county issues; and if the property sits in a local historic district or historic overlay, the Certificate of Appropriateness comes before either. Wilmington's downtown historic district was expanded in 2003 and now reaches from Greenfield Lake to Martin Luther King Boulevard and from the riverfront to 15th Street — a far larger footprint than most applicants assume.
This guide covers Wilmington, North Carolina, in New Hanover County. Wilmington, Delaware is a different (and smaller) city, and there are Wilmingtons in Ohio, Massachusetts, and California. Locally, note that Carolina Beach is also permitted by New Hanover County while keeping its own zoning.
Wilmington permits: record types and what each covers
Wilmington's records split across two authorities, and knowing which one owns each is the difference between a smooth project and a stalled one. These are the records you will file:
Residential permit types

A Wilmington rooftop array is a New Hanover County electrical-led record with city zoning behind it — and in a local historic district, a Certificate of Appropriateness ahead of both, because panels visible from the street are an exterior alteration.
Roofing permits in Wilmington
Reroofs are county permits like everything else structural here. In a local historic district the COA governs the material and appearance, which is where a routine reroof becomes a design review.
Solar covenants and the roofing permit exemption are set by state law, and utilities run interconnection on their own timeline. North Carolina rules
Wilmington permit cost
Wilmington building permit costs come from two schedules. The construction permit fee is New Hanover County's, charged in the COAST portal, with trade permits billed separately. The city's zoning permits, entitlement applications, and Certificates of Appropriateness are charged on the city's own schedule through the DPS platform.
Coastal costs sit outside both. CAMA permit fees are set by the state and adjusted to the Consumer Price Index from July 1, 2025 on a four-year cycle under G.S. 143B-279.19, so any figure from an older handbook understates the current cost.
| Fee component | How it works |
|---|---|
| Building permit | New Hanover County fee schedule, paid in COAST |
| Trade permits (E/P/M) | County records, charged separately |
| City zoning permit | City of Wilmington schedule, paid through DPS |
| Certificate of Appropriateness | City schedule; minor and major works priced differently |
| CAMA permit | State-set, CPI-adjusted from July 1, 2025 |
| Re-inspection | Charged by the county on failed inspections |

Wilmington trade permits
Wilmington trade permits for electrical, plumbing, and mechanical work are New Hanover County records filed in COAST by the state-licensed contractor, not city records — the same split that governs the building permit.
Electrical permits
County records for services, panel upgrades, circuits, EV chargers, and solar interconnection. Electrical work takes a contractor licensed by the NC State Board of Examiners of Electrical Contractors, unless owners wire their own home that is not for sale or rent.
Plumbing permits
County records for new piping, repipes, fixtures, gas piping, and non-identical water heater changeouts; CFPUA coordination applies on connections.
Mechanical (HVAC) permits
County records for installations, non-identical changeouts, ductwork, and refrigeration. Coastal corrosion drives equipment selection more than the code does.
Historic district work
In a local historic district the Certificate of Appropriateness governs exterior work regardless of trade — including replacement windows, siding, and roofing that would otherwise be routine.

Get a free quote →Wilmington permit application: how to apply step by step
Here is how to get a building permit in Wilmington, from confirming the requirement through to close-out. Each step below corresponds to a real decision point where projects commonly stall.
The county issues the building permit; the city approves zoning first; historic districts add a Certificate of Appropriateness ahead of both.
Wilmington's historic districts are larger than most people expect, and CAMA attaches wherever the parcel sits inside an Area of Environmental Concern.
Zoning permits, entitlement applications, and COAs all run through the city's Development & Permitting Services online platform.
Once city zoning has approved, the New Hanover County building and trade records proceed in the county portal.
Coastal clearance is a separate approval on a separate clock. Starting it late is the most common coastal delay in North Carolina.
Pay each authority on its own schedule, request county inspections before 3:30 p.m. for next business day, and close out to your certificate.
Inspections in Wilmington
Wilmington inspections are New Hanover County inspections, requested in COAST with a 3:30 p.m. cutoff for next-business-day service. The county performs roughly 300 inspections a day, and the assigned inspector's name and number appear under Today's Inspections in the portal.
Historic district work adds a compliance layer the building inspector does not carry: the Certificate of Appropriateness conditions are enforced by the city, and finishing work that departs from an approved COA is a city problem even when the county has signed off. If the local inspection department will not inspect within two business days of the request, the permit holder may ask the State Fire Marshal in writing to send an inspector (G.S. 143-139.4). G.S. 160D-1104 also requires the inspector to carry out every inspection requested for a scheduled visit and to point out each part of the work that fails the code.
State law sets how long a North Carolina permit stays valid and when changes need written approval. North Carolina rules

Who issues building permits in Wilmington, NC?
New Hanover County Building Safety issues all building permits inside the city limits. There is no city building permit counter. The City of Wilmington's Zoning Section must approve the application before the county will issue, so the city approval is a precondition rather than a separate permit.
What does the City of Wilmington actually permit?
Zoning permits, entitlement applications, and Certificates of Appropriateness, all through its Development & Permitting Services online platform. The building and trade records live in the county's COAST portal instead.
Do I need a Certificate of Appropriateness in Wilmington?
If the property is in a local historic district or historic overlay and you are altering the exterior, yes. COAs come in minor works and major works tracks, and a building permit does not substitute for one — the COA comes first.
How large is Wilmington's downtown historic district?
Larger than most applicants expect. It was expanded in 2003 and now runs from Greenfield Lake to Martin Luther King Boulevard, and from the Cape Fear riverfront to 15th Street. Check the district maps against the parcel rather than assuming.
Do CAMA rules apply in Wilmington?
Yes, where the project falls inside an Area of Environmental Concern. New Hanover is one of North Carolina's 20 CAMA counties, and the Wilmington office of the NC Division of Coastal Management administers the standards locally.
What is Wilmington's Land Development Code?
The city's rulebook for development, building, and land use, administered under the framework of G.S. Chapter 160D. It divides the city into residential, business, and industrial districts, with residential districts including R-15, R-10, R-7, and the multi-family categories.
How do I run a Wilmington permit search?
Building permit records live in New Hanover County's COAST portal, since the county issues them. City records — zoning, entitlements, and COAs — are tracked in the city's DPS platform.
How do I schedule an inspection in Wilmington?
Through the county's COAST portal, with a 3:30 p.m. cutoff for next-business-day service. The county performs roughly 300 inspections a day, and your assigned inspector's contact details appear in the portal.
Is Wilmington, NC the same as Wilmington, Delaware?
No — different cities in different states with entirely separate permitting systems. Wilmington, North Carolina is the New Hanover County seat on the Cape Fear River, with an estimated 126,809 residents in 2025 (Census).
Who handles water and sewer in Wilmington?
The Cape Fear Public Utility Authority for much of the area, with approvals running alongside the building permit rather than inside it. Utility coordination is a third track beside the city and county approvals.
When is a general contractor licence required in Wilmington?
On projects of $40,000 or more, under G.S. 87-1 and the NC Licensing Board for General Contractors, with tiers capping single-project value at $750,000, $1,500,000, or without limit excluding land cost.
Does a use permit differ from a zoning permit in Wilmington?
Yes. Use permits ensure specific land uses are reviewed and permitted under the zoning ordinance, and are a distinct record from the zoning permit that clears a building application. The city's Planning Department handles questions on both.
