N.D. Cent. Code § 43-07-07
43-07-07. Classes of licenses - License fees - License renewal fees
43-07-07. If any contractor applies for a renewal under a class different from the
license previously issued, the new class license may be issued upon the payment of
the fee required for the issuance of the license of the class applied for. If any
contractor fails to file an application for a certificate for the current contractor year by
the March first deadline, the contractor's license is not in good standing and the
contractor is deemed to be unlicensed within the meaning of section 43-07-02. Within
sixty days after March first, the registrar shall notify the contractor by mail that the
contractor's license is not in good standing. The contractor then has until June first to
renew by paying a penalty fee of fifty dollars, filing an application for a certificate for
the current contractor year, and paying the renewal fee. A contractor who applies for a
certificate for the current contractor year before or within ninety days of the filing
deadline is not subject to the investigation authorized in section 43-07-09. After the
June first deadline any licenses not renewed are expired. Any application for a
certificate for the current contractor year must be fully completed within sixty days of
the date the application is received by the registrar or the registrar shall return the
application to the contractor who then is subject to section 43-07-09. The registrar may
destroy all renewals provided for in this section after the renewals have been on file for
six years.
