Unless a longer time period shall be specifically established as a condition of approval, a Variance shall lapse and shall become void one year following the date on which the Variance became effective, unless prior to the expiration of one year a building permit is issued and construction is commenced and diligently pursued toward completion on the site which was the subject of the Variance application, or a certification of occupancy is issued for the site or structure which was the subject of the Variance if no building permit or certificate of occupancy is required.

A Variance subject to lapse may be renewed by the Board for an additional period of one year, provided that prior to the expiration date, a written request for renewal is filed with Board.

The Board may grant or deny any application for renewal.
