There are many different types of signs with various shapes, locations and messages, but they can generally be grouped in the following types:
Ground Pole Signs
A ground pole sign is a sign which is supported by one or more poles, uprights or braces in or upon the ground, which are not a part of a building.
A wall sign is a sign which is attached to, and/or affixed to, the face of a building or structure. A wall sign can not extend more than 24" from the face of the exterior wall to which it is attached.
A temporary sign is a sign, banner, inflatable or other advertising device constructed of wood, cloth, canvas, fabric or other light material, with or without a structural frame, intended for a limited period of display, including decorative displays for holidays or public demonstrations. A mobile temporary sign is a sign supported on a mobile frame, with or without wheels, and includes the "trailer sign."
A directional sign is an on-premise sign containing noncommercial messages, including, but not limited to, designation of rest rooms, telephone locations, restrictions on smoking and door openings. A directional sign may also be used for private traffic control.
