Building Permits in Wilmington, North Carolina

Within Wilmington city limits, New Hanover County Department of Permits & Inspections issues building permits, while the City handles zoning and related land-development review. Building-permit applications are submitted through the County's COAST portal.

Current codes

North Carolina OSFM currently identifies the 2018 North Carolina State Building Code family as the effective code, with the 2020 Electrical Code, while implementation of the 2024 State Building Code remains delayed. The State expressly says the 2018 code remains in effect until the statutory conditions for the newer code are satisfied.

When a permit is required

Wilmington states that a building permit is required for construction of buildings and structures, changes of building use, demolition, alterations/remodeling, upfits, expansions, accessory structures, mobile homes and new construction/relocation within city limits. Applicants should verify zoning compliance with the City before applying to the County.

Historic properties, fees and timing

Alterations in local historic districts or overlay districts may require a Certificate of Appropriateness. Building-permit fees and review timing are administered through New Hanover County and depend on project scope; no generic estimate is supplied here.
