Section 302.7 of the International Property Maintenance Code is hereby amended to read as follows:

302.7 Accessory structures. Accessory structures, including detached garages, outbuildings, sheds, fences, and walls, shall be maintained structurally sound and in good repair. Areas that are leaning, buckling, sagging or deteriorating shall be repaired or replaced with materials compatible with the undamaged portions of the fence or removed.

Such screening shall be constructed and maintained in accordance with applicable City codes and shall be adequate to prevent substantial viewing of the enclosed objects from any place within the adjacent property or any structure located on that property.

Notwithstanding any other applicable provisions, permitted items, objects or structures shall occupy no more than twenty percent (20%) of the allowable outside storage area. In measuring the area occupied by such items, objects or structures to determine if the permitted twenty percent (20%) is exceeded, a rectangle shall be constructed to include all points where any such item, object or structure is located, and the area shall be calculated to include all that area within the rectangle. This method of calculating area shall not apply to those items specifically authorized in subsections (a), (b) or (c) above.
