Wilmington ADU Permitting Overview

Accessory Dwelling Units are allowed on many single-family and multifamily properties in Wilmington, but approvals depend on parcel-specific criteria and local zoning standards. Planning a Wilmington ADU usually involves reviewing setback rules, height restrictions, lot coverage limits, parking provisions, utility tie-ins, and any neighborhood or overlay guidelines that may apply. Lots with irregular shapes, shared driveways, or older utility infrastructure can sometimes require additional planning for access, drainage, or service upgrades.

Our feasibility assessment reviews parcel dimensions, zoning designations, existing structures, utility availability, and site accessibility to outline the most practical approval pathway for Wilmington Multifamily ADU projects. Final eligibility and design direction, however, always depend on the individual property characteristics and the most current municipal regulations in effect at the time of submission.
