County vs. City Zoning
Most Castle Hayne properties are in unincorporated New Hanover County — not within Wilmington city limits. This often means different (and sometimes more flexible) ADU regulations, lot coverage rules, and setback requirements.

Castle Hayne's rural character and large lot sizes make it one of the best-kept secrets for ADU construction in the greater Wilmington area — more space, more flexibility, and lower density.

Why Castle Hayne Makes Sense for an ADU
Castle Hayne occupies a unique position in the Wilmington market: it's just minutes from downtown and the port, but its semi-rural character means homeowners often have significantly more land than their counterparts in suburban Wilmington neighborhoods. Many Castle Hayne properties range from a half-acre to several acres — prime territory for detached ADUs and backyard cottages with genuine separation and privacy.
The area has historically attracted homeowners who want space without sacrificing proximity to Wilmington's amenities. That same quality-of-life draw is now attracting renters, especially remote workers and families who don't need to commute daily. ADUs in Castle Hayne that attract this demographic can command strong long-term rents at $1,000–$1,600/month.
Because much of Castle Hayne falls under unincorporated New Hanover County zoning (rather than City of Wilmington rules), the permitting landscape is often more straightforward for larger ADU footprints. We handle New Hanover County permits routinely and know what to expect at every stage.
