Sec. 9-4.2811. Revocation.
   A petition for the revocation of any variance or permit may be filed by any person or political entity aggrieved, or by any officer, department, board, or commission of the City affected by the decision.
   Any variance or permit heretofore or hereafter granted may be revoked by the Commission after appropriate proceedings, as provided in this article, for any of the following causes:
   (a)   That any term or condition of the variance or permit has not been complied with;
   (b)   That the property subject to the variance or permit, or any portion thereof, is used or maintained in violation of any statute, law, or regulation;
   (c)   That the use for which the variance or permit was granted has not been exercised for at least twelve (12) consecutive months, or has ceased to exist, or has been abandoned; and
   (d)   That the use for which the variance or permit was granted has been so exercised as to be detrimental to the public health or safety or as to constitute a nuisance.
   After the revocation of a variance or permit, the property affected thereby shall be subject to the regulations of the applicable zone classification. The failure of the Commission or Council to revoke a variance or permit whenever cause therefor exists or occurs shall not constitute a waiver of such right with respect to any subsequent cause for revocation.
