(A) A wall sign may be placed upon the front, rear, or side wall of any building. However, such wall sign shall not extend beyond the building line more than 18 inches and shall be safely and adequately attached to the building wall by means of iron or metal anchors, bolts, or expansion screws of not less than five-eighths of an inch in diameter. No wooden plugs or anchorage with wood in connections or nails shall be considered sufficient for proper anchorage.
(B) If a wall sign is illuminated, overhead lighting reflectors may project six feet from the face of the bulletin or sign. All reflectors extending over the sidewalk shall be secured and safely anchored. No wall sign shall be so erected as to cover the doors and windows of any building in common use or otherwise prevent free ingress to or egress from the building or any fire escape.
