(a) Sign located within the sign band
A commercial establishment located on the ground floor of a building may have one sign located on each street frontage within a sign band as defined in this Section.
The sign band shall have a lower limit of 10 feet above curb level and an upper limit coincident with the bottom of the lowest window sill on the second floor of a building, but in no event more than 15 feet above curb level. A sign located within the sign band may be applied directly to the surface of a building or to a sign board affixed to the surface of a building. If a sign board is employed, such sign board shall be entirely within the sign band, shall be mounted horizontally, shall have a uniform color over its entire surface excluding perimeter frame or trim and shall extend the full length of the street wall of the establishment to which it is accessory, except that such sign board may be interrupted by vertical architectural elements such as columns, pilasters or other integral architectural elements. Any background material shall be considered as a sign board, unless it extends the full length of the street wall of a building (or that portion of a building occupied by the establishment) and the full height of the building up to the topmost cornice. On corner lots, a sign or sign boards shall be the same vertical dimension and shall be mounted at the same height above the curb level on both street frontages.
If more than one commercial establishment is located on the ground floor of a building, the signs located within the sign band accessory to each such establishment shall consist of letters and symbols of approximately the same size for each establishment, either applied directly to the surface of the building or to a common sign board affixed to the surface of a building.
As of March 16, 1978, the owner or lessee of a building with more than one ground floor establishment shall be responsible (unless the sign is applied directly to the surface of the building) for specifying the requirements of a common sign board, which shall include, but are not limited to, vertical dimension, mounting height, background color, material, whether illuminated and method of illumination (if applicable) which shall be the same for each establishment and shall be adhered to by each establishment employing a sign board.
A sign accessory to uses on the upper floors of a building may be located within the sign band when it directs attention to a ground floor entrance of an establishment located on the upper floors of a building.
(b) Signs located below the sign band
Signs accessory to commercial establishments located on the ground floor of a building may be located between curb level and 10 feet above curb level. Signs in show windows, on doors, or on transoms above doors, shall not occupy more than 20 percent of the total area of such show windows, doors or transoms above doors in which they are displayed, and are limited to writing (including letter, word or numeral) not more than eight inches high. Such sign shall be applied directly to show windows, doors or transoms above doors, without background, or to a transparent panel hung behind the plane of the show window surface, door or transom above a door. Non-flashing illuminated signs (such as neon, etc.) shall be permitted providing that such signs are essentially transparent, i.e., without background or enclosure.
Incidental signs, identifying store name, address and hours of operation shall not exceed 10 square feet (including background) for an individual sign and shall not exceed, in aggregate (square feet), one-fifth the street frontage of the establishment but in no event more than 50 square feet for interior or through lots or 50 square feet on each frontage for corner lots.
An establishment located above the ground floor of a building that has an entrance on the ground floor may have one sign directing attention to the entrance.
(c) Signs located above the sign band
Signs accessory to commercial establishments which occupy space above the ground floor of a building may be located between 20 feet and 40 feet above curb level. Such establishments may have signs in windows provided that such sign does not occupy more than 30 percent of the window to which it is applied, that the remainder of the window is transparent, and that all such signs for an establishment have similar size and style of writing, pictorial representation, emblem or any other figure of similar character. Commercial establishments which occupy space above the ground floor may have one sign located above the sign band which is applied directly to the surface of a building or to a sign board affixed to the surface of a building. If a sign board is employed, such sign board shall be mounted horizontally, shall have a uniform color over its entire surface, excluding perimeter frame and trim, and shall not be located between windows. The total surface area of all signs located above the sign band shall not exceed three times the street frontage of the zoning lot (in feet) but in no event more than 200 square feet on each frontage.
No sign or sign board shall extend above the parapet wall or shall obscure any cornice or window.
