If the construction activity for which a building permit has been issued has not been commenced within 150 days from the date of its issuance, the permit shall expire by operation of law and shall no longer be of any force or effect. However, the Building Commissioner may, for good cause shown in writing, extend the validity of any such permit for an additional period which is reasonable under the circumstance, but in no event shall the continuance exceed a period of 60 days. Such extension shall be confirmed in writing. If the construction activity has been commenced but only partially completed, and thereafter substantially no construction activity occurs on the construction site over a period of six months, the permit shall expire by operation of law and no longer be of any force or effect. However, the Building Commissioner may, for good cause shown in writing, extend the validity of any such permit for an additional period which is reasonable under the circumstances to allow re-initiation of the construction activity.
