It shall not be lawful for any person to erect any hut, shed or range or block of huts or sheds, or to add any hut or shed to any range or block of huts or sheds already existing when this Act comes into operation, without giving previous notice to the municipal council and obtaining its permission and the municipal council may require such huts or sheds to be built so that they may stand in regular lines, with a free passage or way in front of and between every two lines of such width as the municipal council may think proper for ventilation and to facilitate scavenging, and at such a level as will admit of sufficient drainage, and may require such huts to be provided with such number of privies and such means of drainage as to it may seem necessary. If any hut or shed or range or block is built without giving such notice to the municipal council, the municipal council may give written notice to the owner or builder thereof or to the owner or occupier of the land on which the same is erected or is being erected, requiring him within such reasonable time as shall be specified in the notice to take down and remove the same, or to make such alterations therein or additions thereto as, having regard to the sanitary considerations, the municipal council may think fit.
