North Carolina General Statutes Chapter 160A. Cities and Towns § 160A-58.7. Annexation of municipal property

(a) The city council may initiate annexation of property not contiguous to the primary corporate limits and owned by the city by adopting a resolution stating its intent to annex the property, in lieu of filing a petition. The property must satisfy the requirements of G.S. 160A-58.1. The resolution shall contain an adequate description of the property and fix a date for a public hearing on the question of annexation. Notice of the public hearing shall be published once at least 10 days before the date of the hearing. At the hearing, any resident of the city may appear and be heard on the question of the desirability of the annexation. If the council finds that annexation is in the public interest, it may adopt an ordinance annexing the property. The ordinance may be made effective immediately or on any specified date within six months from the date of passage.

(b) A city has no authority to adopt a resolution or petition itself under this Part for annexation of property it does not own or have any legal interest in. For the purpose of this subsection, a city has no legal interest in a State-maintained street unless it owns the underlying fee and not just an easement.
