N.C. Gen. Stat. § 89C-17
Certificates for licensure of corporations and business firms that engage in the practice of engineering or land surveying shall expire on the last day of the month of June following their issuance or renewal and shall become invalid on that date unless renewed. All other certificates for licensure shall expire on the last day of the month of December next following their issuance or renewal, and shall become invalid on that date unless renewed. When necessary to protect the public health, safety, or welfare, the Board shall require any evidence necessary to establish the continuing competency of engineers and land surveyors as a condition of renewal of licenses. When the Board is satisfied as to the continuing competency of an applicant, it shall issue a renewal of the certificate upon payment by the applicant of a fee fixed by the Board but not to exceed seventy-five dollars ($75.00). The secretary of the Board shall notify by mail or email every person licensed under this Chapter of the date of expiration of the certificate, the amount of the fee required for its renewal for one year, and any requirement as to evidence of continued competency. The notice shall be sent by email or mailed at least one month in advance of the expiration date of the certificate. Renewal shall be effected at any time during the month immediately following the month of expiration, by payment to the secretary of the Board of a renewal fee, as determined by the Board, which shall not exceed seventy-five dollars ($75.00). Failure on the part of any licensee to renew the certificate annually in the month immediately following the month of expiration, as required above, shall deprive the licensee of the right to practice until reinstatement of the license. The license may be reinstated at anytime during the first 12 months immediately following the date the license became invalid by payment of a reinstatement fee of one hundred dollars ($100.00) in addition to the established renewal fee. Failure of a licensee to reinstate the license during the first 12 months immediately following the date the license became invalid shall require the individual, prior to resuming practice in North Carolina, to submit an application on the prescribed form, and to meet all other requirements for licensure as set forth in Chapter 89C. The secretary of the Board is instructed to remove from the official roster of engineers and land surveyors the names of all licensees who have not effected their renewal by the first day of the month immediately following the renewal period. The Board may adopt rules to provide for renewals in distress or hardship cases due to military service, prolonged illness, or prolonged absence from the State, where the applicant for renewal demonstrates to the Board that the applicant has maintained active knowledge and professional status as an engineer or land surveyor, as the case may be. It shall be the responsibility of each licensee to inform the Board promptly concerning change in address. A licensee may request and be granted inactive status. No inactive licensee may practice in this State unless otherwise exempted in this Chapter. A licensee granted inactive status shall pay annual renewal fees but shall not be subject to annual continuing professional competency requirements. A licensee granted inactive status may return to active status by meeting all requirements of the Board, including demonstration of continuing professional competency as a condition of reinstatement.
