(1) Every person shall, within one month after the completion of the erection of the whole or part of the building, deliver or send or cause to be delivered or sent to the Executive Officer a notice in writing of such completion or part of completion accompanied by a certificate in the Form prescribed by bye-laws made in this behalf and shall give to the Executive Officer all necessary facilities for the inspection of such building or part of the building.
(2) No person shall occupy or permit to be occupied any such building or use or permit to be used any building or part thereof until permission has been granted by the Executive Officer in this behalf in accordance with the bye-laws made under this Act :
Provided that if the Executive Officer fails within a period of thirty days after the receipt of the notice of completion to communicate his refusal to grant such permission, such permission shall be deemed to have been granted.
(3) Every sanction for the erection or re-erection of any building which shall be given or be deemed to have been given by a municipality, shall remain in force for two years only from the date of such sanction or for such longer period as the municipality or the Executive officer or Secretary, as the case may be, may have allowed when conveying sanction under sanction 203. Should the erection or re-erection of the building not have been commenced within one year and completed within three years or such longer period as may have been allowed by the municipality, the sanction shall be deemed to have lapsed but such lapse shall not bar any subsequent application for fresh sanction under the foregoing provisions of the Act.
