N.C. Gen. Stat. § 143B-1257
The mayor may remove a commissioner for inefficiency or neglect of duty or misconduct in office, but only after the commissioner shall have been given a copy of the charges against him (which may be made by the mayor) at least 10 days prior to the hearing thereon and had an opportunity to be heard in person or by counsel.
If, after due and diligent search, a commissioner to whom charges are required to be delivered hereunder cannot be found within the county where the authority is located, such charges shall be deemed served upon such commissioner if mailed to him at his last known address as same appears upon the records of the authority.
In the event of the removal of any commissioner, the mayor shall file in the office of the city clerk a record of the proceedings, together with the charges made against the commissioner removed, and the findings thereon.
