No building permit for any lot shall be issued except to the owner of record thereof, or an authorized agent, until the construction or alteration of a building or structure, as proposed, shall comply in all respects with the provisions of this bylaw or with a decision rendered by the Board of Appeals. Any application for such 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 and size of all buildings or structures already on the lot, the location of new buildings 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. Applications for permits with their accompanying plans and building permits shall be maintained as a permanent record by the Board of Selectmen or a Building Inspector appointed by them.
