It shall be unlawful for any owner or person to erect, construct, reconstruct, or alter a structure or change the use or lot coverage, increase the intensity of use, or extend or displace the use of any building or other structure on a lot without applying for and receiving from the Building Inspector the required building permit therefor. For purposes of administration, such permit and application procedure involving a structure may be made at the same time and combined with the permit required under the Building Code. An application for a permit shall be accompanied by a plan, accurately drawn, showing the actual shape and dimensions of the lot to be built upon, the exact location of new buildings or structures to be constructed, together with the lines within which all buildings or structures are to be erected, the existing and intended use of each building or structure and such other information as may be necessary to provide for the execution and enforcement of this bylaw.
