N.C. Gen. Stat. § 89A-5
Every registrant under this Chapter shall, on or before the first day of July in each year, obtain a renewal of a certificate for the ensuing year, by application, accompanied by the required fee. Upon failure to renew, the certificate shall be automatically revoked. The certificate may be renewed at any time within one year after its expiration if the applicant pays the required renewal fee and late renewal penalty, and the Board finds that the applicant has not used his or her certificate or title or engaged in the practice of landscape architecture after notice of revocation and is otherwise eligible for registration under the provisions of this Chapter. When necessary to protect the public health, safety, or welfare, the Board shall require such evidence as it deems necessary to establish the continuing competency of licensees as a condition of license renewal.
