Within its powers, the Board of Appeals may reverse or affirm, wholly or in part, the decision being appealed, and to that end shall have all the powers of the officers from whom the appeal is taken, and it may direct the issuance of a permit or certificate.
(a) The Board of Appeals shall render a decision on the appeal within thirty-five (35) days from the date of the hearing unless an extended period of time is mutually agreed upon by the applicant and the Board.
(b) The Board shall notify the appellant in writing of the decision of the Board.
(c) The Zoning Administrator shall keep minutes of all proceedings upon appeal, showing the vote of each member thereon, and shall keep record of the Board's official actions.
(d) Any decision or order rendered by the Board of Appeals, under this Chapter or the Charter, that authorizes the issuance of a permit or certificate, shall be subject to the following limitations and restrictions:
(1) Such decision or order and the rights and conditions contained therein, shall apply only to the appellant whose application for a permit has been denied, and may not be assigned or transferred by such appellant to or for the benefit of any successor in interest. Any request for any such assignment or transfer shall be deemed a new matter and subject to the administrative review and variance procedures then in effect.
(2) Such decision or order shall become invalid and shall be considered null and void unless the construction of the project authorized by it shall have been substantially commenced within twelve (12) months of the date of such decision or order, or of the effective date of any required approval thereof by Council. In the case of new construction, the term "substantially commenced" means that the work shall have progressed at least to the completion of the foundation walls to grade level. Any request for an extension or continuation of such one-year limitation shall require that the original variance or appeal be reheard and considered as a new matter with evidence regarding current conditions and current code provisions considered.
(3) In the event that the construction is commenced as hereinabove provided, and then is suspended or abandoned for such a period of time as to invalidate the building permit or the Zoning Certificate under which the work is authorized, then such decision or order of the Board of Appeals shall become invalid simultaneously with the invalidity of such building permit or Zoning Certificate.
