An appeal for a variance shall stay all proceedings and furtherance of the action appealed from, unless the Building Commissioner certifies to the Zoning Board of Appeals, after notice of appeal has been filed with him or her, that by reason of facts stated in the certificate a stay would, in his or her opinion, cause imminent peril to life or property. In such a case, the proceedings shall not be stayed otherwise than by a restraining order, which may be granted by the Board or by a court of record on application, with notice to the officer from whom the appeal is taken, and upon due cause being shown.
