(1) The Administrator shall refuse to sanction the erection of any building in contravention of any rules made under sub-section (2) of section 4. (2) The Administrator shall, in every case, communicate the sanction or rejection of a building application within sixty days of its receipt. (3) Where no communication is received by the applicant from the Administrator within the period specified in sub-section (2), the application shall be deemed to have been sanctioned and the applicant may, after fifteen days’ notice to the Administrator, erect or re-erect the building in accordance with the building application submitted by him to the Administrator for sanction notwithstanding that such erection or re-erection contravenes the rules made under section 4: Provided that when the Administrator modifies the building application within such fifteen days and communicates the modification to the applicant, the applicant shall erect or re-erect the building in accordance with such modification.
