An appeal stays all proceedings in furtherance of the action appealed from, unless the Zoning Administrator from whom the appeal is taken certifies to the Board of Appeals after the notice of appeal is filed with the Administrator, that by reason of facts stated in the application, a stay would, in his opinion, cause imminent peril to life and property, or unless such proceedings were implemented pursuant to Section 1141.21, Abatement of Violations. In such case, proceedings shall not be stayed other than by a restraining order which may be granted by the Board of Appeals or by a court of competent jurisdiction on application and upon notice to the Zoning Administrator from whom the appeal is taken, and on due cause shown.
