In the event the City Building Inspector shall find that the activity is violating any of the conditions imposed upon the activity, or if the activity shall have failed to comply with those conditions, then the Inspector may immediately order the permit cancelled, suspended, or revoked and the activity closed forthwith, which shall remain closed until such time as compliance with the conditions has been effected or until the applicant shall have requested and obtained a special meeting of the Board of Appeals and paid the cost thereof and obtained a waiver of the conditions from the Board of Appeals. Any request for a special meeting of the Zoning Board of Appeals shall be accompanied by the payment of the fee for a special meeting of the Zoning Board of Appeals. At that hearing the Board of Appeals may order the permit cancelled, revoked, or suspended until the conditions are complied with or may order the permit reinstated.
