(A)   Plans, specifications, and owner's consent. Before any permit is granted for the erection of a sign, plans and specifications shall be filed with the Department permitting division showing the dimensions, materials, and required details of construction, or alteration, including loads, stresses,  anchorage, illumination details, location and description of all existing signs on the property, and the sign's location in relation to other structures and to property lines and all required information on the permit application.  The location shall include an address and block and lot number. The applications shall be accompanied by the written consent of the owner or lessee of the premises upon which the sign is to be erected.  Signs listed as exempt within the Land Development Code will not be required to comply with this section.
   (B)   Permits.  A new sign shall not hereafter be erected, constructed, or altered, except as herein provided and until after a permit has been issued by the Louisville Metro.  Any permit issued shall become invalid if the authorized work is not commenced within 180 days after issuance of the permit, or if the authorized work is suspended or abandoned for a period of six months after the time of commencing the work.  Signs listed as exempt within the Land Development Code will not be required to comply with this section.
   (C)   Identification.  Every portable sign  shall have affixed to it a decal (with expiration date) which evidences compliance with standards contained in this chapter and which shall be obtained from the Department.  This decal shall be maintained on the face or edge of the sign in a location legible from the sidewalk level or ground level.
   (D)   Alterations.  A sign shall not be enlarged or relocated except in conformity to the provisions of this chapter until a proper permit has been secured.  The changing of movable parts of an approved sign that is designed for such changes, or the repainting or reposting of display matter, shall not be deemed an alteration, provided the conditions of the original approval and the requirements of this chapter are not violated.
