If the work authorized by a permit is not started within 540 days after issuance of the permit, the permit expires by operation of law and may not be reinstated. If the work authorized by a permit ceases for a consecutive period of 730 days, the permit expires by operation of law and may not be reinstated. A failure to request inspection as required by Chapter 14A-5 shall create a rebuttable presumption that work has not started or has ceased.
