Wilmington has a distinctive split: New Hanover County Building Safety issues the building permit for projects inside the City of Wilmington, while the City of Wilmington Development & Permitting Services (DPS) handles zoning permits, entitlements, and Certificates of Appropriateness (COAs). The City's Zoning Section must approve a building-permit application within city limits before the County issues it.
This Wilmington building permit guide covers what requires a permit, how the county/city split works, fees, COAs, trade permits, and inspections — so your Wilmington project starts clean.
This guide covers projects inside Wilmington city limits. Although the City handles zoning, entitlements, and COAs, New Hanover County Building Safety issues the actual building permits and performs inspections. Wilmington is coastal (wind and flood considerations) and includes large local historic districts where exterior work needs a Certificate of Appropriateness.
What requires a building permit in Wilmington?
Under the North Carolina State Building Code (and N.C.G.S. 160D-1110, which requires permits for most construction), a permit is required before you construct, reconstruct, alter, repair, move, demolish, or change the occupancy of most structures and systems. Common triggers include:
Permit required
- New construction, additions, and relocations
- Structural / load-bearing alterations and demolition
- Remodels, alterations, upfits, and expansions
- Electrical service changes and most wiring alterations
- Mechanical / HVAC installations and changeouts
- Plumbing alterations, repipes, and water heaters
- Accessory structures and mobile/manufactured homes
- Change of building use or occupancy
Typically exempt
- Painting, flooring, cabinetry, and cosmetic work
- Like-for-like fixture/device swaps by a licensed contractor
- Routine maintenance not altering structure or systems
- Minor work expressly exempt by code (confirm first)
Exemptions are narrow and scope-specific. When unsure, confirm with the building department before starting — see the penalty note below.
Get both approvals before starting work. The City's zoning approval (and any required COA) must be in place before New Hanover County issues the building permit; building without permits exposes the owner to penalties and stop-work orders.
Who handles permitting in Wilmington?
Building permits and inspections run through New Hanover County Building Safety; zoning permits, entitlements, and Certificates of Appropriateness run through the City of Wilmington Development & Permitting Services. Water and sewer service is handled by the Cape Fear Public Utility Authority (CFPUA).
| Detail | Information |
|---|---|
| Building permits / inspections | New Hanover County Building Safety — 910-798-7308; Coast@nhcgov.com |
| Zoning / entitlements / COAs | City of Wilmington DPS — Planning 910-254-0900 |
| Water & sewer | Cape Fear Public Utility Authority (CFPUA) — 910-332-6550 |
| City portal | DPS online platform (zoning, entitlements, COAs) |
| County portal | New Hanover County Permits & Inspections (building/trade) |
| Enforced code | NC State Building Code (coastal wind/flood) |
Use both portals. Apply for zoning permits, entitlements, and Certificates of Appropriateness through the City of Wilmington DPS online platform; apply for building and trade permits — and schedule inspections — through the New Hanover County permits portal. The City's zoning approval must be secured before the County issues the building permit, and CFPUA handles water/sewer availability.
Wilmington building permit cost
Wilmington-area fees combine City review fees (zoning, entitlements, COAs) with New Hanover County building and trade permit fees, each set by the respective fee schedule and based on the type and valuation of work.
Coastal projects may carry additional wind/flood review, and CFPUA assesses its own utility fees. Confirm current amounts before budgeting.
| Fee component | How it works |
|---|---|
| City zoning / COA fees | Per City of Wilmington fee schedule |
| County building permit fee | Per New Hanover County fee schedule |
| Trade permits (E / P / M) | Charged separately per trade (County) |
| CFPUA utility fees | Water/sewer connection & capacity |
| Lien agent | Designate via LiensNC for projects $30,000+ |
| Work-without-permit | Penalties and possible stop-work orders |

Wilmington trade permits
Electrical, plumbing, and mechanical work needs its own permit and a North Carolina-licensed contractor, filed with New Hanover County.
Electrical permits
Required for service upgrades, panels, solar PV, and most wiring, performed by a NC-licensed electrical contractor.
Plumbing permits
Required for new plumbing, repipes, water heaters, fixtures, and gas piping, performed by a NC-licensed plumbing contractor; CFPUA coordinates water/sewer service.
Mechanical (HVAC) permits
Required for HVAC changeouts, ductwork, and refrigeration, performed by a NC-licensed contractor. Coastal equipment anchoring may apply.
Miscellaneous & specialty
Reroofs, accessory structures, and signs are permitted separately. Exterior work in a local historic district requires a Certificate of Appropriateness from the City, and coastal wind/flood requirements affect design and elevation.
Verify your contractor's license. North Carolina requires a state General Contractor license from the NC Licensing Board for General Contractors for projects costing $40,000 or more, plus separate state licenses for electrical (NC Board of Examiners of Electrical Contractors) and plumbing/heating (NC State Board of Examiners of Plumbing, Heating & Fire Sprinkler Contractors). Verify before signing. The property owner is responsible for ensuring a permit is obtained.
How to get a building permit in Wilmington
Confirm jurisdiction & overlays
Confirm the parcel is inside Wilmington and check zoning, historic-district, and flood overlays.
Secure City zoning / COA
Apply through City of Wilmington DPS for zoning approval and any required Certificate of Appropriateness.
Prepare your documents
Assemble the application, stamped plans (coastal wind/flood as applicable), and NC license documentation; designate a lien agent via LiensNC for projects $30,000+.
Apply for the County building permit
Submit the building/trade application to New Hanover County Building Safety once City zoning is approved.
Pay fees & pull the permit
Pay City and County fees (and CFPUA where applicable), then post the permit on site.
Schedule inspections through close-out
Schedule inspections with New Hanover County (Live Remote Inspections where eligible). Clear all inspections to obtain your Certificate of Occupancy.
Inspections in Wilmington
Schedule inspections through New Hanover County Building Safety (Live Remote Inspections are available when eligible); contact Building Safety at 910-798-7308 or Coast@nhcgov.com. Typical checkpoints include footing/foundation, rough-in MEP, framing, insulation, and final.
If a permit is placed on hold by CFPUA or the City of Wilmington, resolve it with that agency before re-inspection; a final inspection and Certificate of Occupancy are required before legal occupancy.
