If construction, erection, location, alteration or use of a building or land which is authorized by a permit issued by the Zoning Administrative Officer, or which is authorized by the Planning Board or the Board of Adjustment as a conditional use or variance is not substantially undertaken within 12 months of the date of issue or authorization, or if there is a failure to comply with the conditions imposed by either Board within the twelve-month period, such zoning permit or authorization shall be void. Nothing herein shall preclude the renewal of such permit or authorization upon proper application.
