Wilmington Accessory Dwelling Unit (ADU) Rules
Some RestrictionsADU Permits
Wilmington's Land Development Code (LDC) Chapter 18 permits accessory dwelling units in most residential zoning districts as accessory uses. Detached ADUs are limited in size and must meet residential setback and lot-coverage standards. Building, electrical, plumbing, and mechanical permits are issued separately under NC General Statute 160D-1110 through Wilmington Development Services and the New Hanover County Inspections Department.

Some RestrictionsADU Impact Fees
Wilmington does not impose a general residential impact fee on ADUs. North Carolina law does not broadly authorize impact fees - they are allowed only where specifically permitted. Cape Fear Public Utility Authority (CFPUA) charges water and sewer System Development Fees under NCGS 162A-205 if a new utility connection is required. Permit and plan-review fees apply to all ADU work.

Few RestrictionsADU Owner Occupancy
Wilmington's Land Development Code does not contain a statewide owner-occupancy mandate for accessory dwelling units - North Carolina has no statewide ADU statute. Applicants should verify the current LDC accessory-use standards at application, as Wilmington has periodically considered owner-occupancy provisions tied to short-term rental concerns. The ADU and principal dwelling must remain on a single lot under common ownership.

Some RestrictionsADU Rental Restrictions
Wilmington permits long-term ADU rentals without a city license. Short-term rentals (under 30 days) are governed by the LDC and by Schroeder v. City of Wilmington (2019) - the controlling NC Court of Appeals case (literally named after Wilmington) that held cities cannot use zoning to outright ban short-term rentals as a registration mechanism. Hosts must collect New Hanover County 6% room occupancy tax plus NC sales taxes.

Wilmington regulates carports as accessory structures under Land Development Code Section 18-249.

Attached carports are treated as part of the principal structure and follow the underlying district setbacks.
