N.C. Gen. Stat. § 153A-443

If a county determines that the traditional location of the "courthouse," the "courthouse door," the "courthouse bulletin board" or the "courthouse steps" has become inappropriate or inconvenient for the doing of any act or the posting of any notice required by law to be done or posted at such a site, the county may by ordinance designate some appropriate or more convenient location for the site. The board of commissioners shall cause such an ordinance to be published at least once within 30 days after the day it is adopted and shall cause a copy of it to be posted for 60 days at the traditional location.
