N.C. Gen. Stat. § 83A-11
Certificates or registrations must be renewed on or before the first day of July in each year. No less than 30 days prior to the renewal date, a renewal application shall be transmitted to each individual and corporate licensee. The completed application together with the required renewal fee shall be returned to the Board on or before the renewal date. When the Board is satisfied as to the continuing competency of an architect or a registered interior designer, it shall issue a renewal of the certificate or registration. Upon failure to renew within 30 days after the date set for expiration, the license or registration shall be automatically revoked but such license or registration may be renewed at any time within one year following the expiration date upon proof of continuing competency and payment of the renewal fee plus a late renewal fee. After one year from the date of revocation, reinstatement may be made by the Board, or in its discretion, the application may be treated as new subject to reexamination and qualification requirements as in the case of new applications.
