Sign type definitions. The following definitions apply to types of signs based on the characteristics of the sign without respect to the content of the message:
ABANDONED SIGN
A sign that no longer identifies or advertises an ongoing business, product, location, service, or activity conducted. Whether a sign has been abandoned shall be determined by the intent of the owner of the sign and shall be governed by applicable case law and statutory law on abandoned structures.
ANIMATED SIGN
A sign that has any visible moving part either constantly or at intervals; flashing, intermittent, or oscillating lights; visible mechanical movement of any description; or other apparent visible movement achieved by any means that move, change, flash, oscillate or visibly alters in appearance to depict action, create an image of a living creature or person, or create a special effect or scene. This definition does not include changeable-copy signs and electronic message center (EMC) signs that are in compliance with this article.
AWNING SIGN
A permanent projecting sign that is painted or screen printed on the exterior surface of an awning.
BALLOON SIGN
A temporary sign that is an air-inflated object, which, unlike air-activated signs, retains its shape. A balloon sign is made of flexible fabric, rests on the ground or structure, and may be equipped with a portable blower motor that provides a constant flow of air into the device. Balloon signs are restrained, attached, or held in place by a cord, rope, cable, or similar method.
BANNER SIGN
A sign on paper, cloth, fabric or other flexible or combustible material of any kind that is attached flat either to a wall or temporarily to a permanent sign face.
BILLBOARD SIGN (OUTDOOR ADVERTISING SIGN)
A permanent freestanding pole sign erected, maintained, and used in the outdoor environment for the primary purpose of the display of commercial or noncommercial messages.
CANOPY SIGN
A permanent projecting sign affixed to the side or bottom surface(s) of an attached or freestanding canopy.
CHANGEABLE-COPY SIGN
A permanent sign or portion thereof on which the copy or symbols change either automatically through electrical or electronic means (e.g., time and temperature units), or manually through placement of copy and symbols on a panel mounted in or on a track system.
ELECTRONIC MESSAGE CENTER (EMC) SIGN
An electrically activated changeable-copy sign whose variable message and/or graphic presentation capability can be electronically programmed. EMCs typically use light emitting diodes (LEDs) as lighting sources.
FESTOONS
A string of ribbons, pennants, spinners, streamers, tinsel, small flags, pinwheels, or lights typically strung overhead and/or in loops.
FLAG
A sign on paper, cloth, fabric or other flexible or combustible material of any kind that is attached to a permanent conforming pole or attached flat to a wall.
FREESTANDING SIGN
A sign supported by one or more uprights, poles, pylons, monuments, or braces placed in the ground and not attached to any building or other structure. Freestanding signs include, but are not limited to, pole signs and monument signs.
INCIDENTAL SIGN
A small sign designed and located to be read only by people within the site and generally not visible or legible from the right-of-way or adjacent properties. Examples of incidental signs include, but are not limited to, credit card signs, signs indicating hours of business, no smoking signs, signs used to designate bathrooms, handicapped signs, traffic control signs that conform to the requirements of the Michigan Manual of Uniform Traffic Control Devices, and other signs providing information to be read at close proximity.
MONUMENT SIGN
A base-mounted, freestanding sign placed in the ground and not attached to any building or other structure. A monument sign shall have a solid supporting base equal to or greater than the width of the sign face constructed of a decorative and durable material (e.g., masonry), and shall have no separations between the sign face and the base.
MURAL
A wall sign that is painted or drawn on the exterior surface of a structure.
POLE SIGN
A type of freestanding sign that is elevated above the ground on poles or braces.
PROJECTING SIGN
A sign attached to a building or other structure and extending beyond the attachment surface by more than 18 inches. A "projecting sign" is differentiated from a "wall sign" based on the distance the sign projects from the surface of the building. Projecting signs consist of "awning signs," "canopy signs," and "marquee signs."
SANDWICH BOARD SIGN
A portable temporary sign or signboard that is freestanding and not permanently anchored or secured to either a building, structure, or the ground. Often referred to as "sidewalk signs," sandwich board signs include, but are not limited to, so called "A" frame, "T" shaped, or inverted "T" shaped stands.
WALL SIGN
A sign attached to, painted on, inscribed, or otherwise set upon the exterior wall or surface of any building, no portion of which projects more than 18 inches from the wall and which may not project above the roof or parapet line.
WINDOW SIGN
A sign that is painted on or attached to a window or glass door that is intended to be viewed from the exterior, including signs located inside a building but visible primarily from the outside of the building.
YARD SIGN
A portable temporary sign or signboard that is freestanding and temporarily anchored or secured to the ground. See also "sandwich board sign."
