Notwithstanding any provision of ORS 307.624, if the city or county finds that construction, addition or conversion of the multiple-unit housing was not completed by the date specified in ORS 307.637, due to circumstances beyond the control of the owner, and that the owner had been acting and could reasonably be expected to act in good faith and with due diligence, the city or county may extend the deadline for completion of construction, addition or conversion for a period not to exceed 12 consecutive months.
