[Code 1964, § 3-21]
(a) 
Definition. As used in this section, "roof signboard" means any sign erected, constructed or maintained upon the roof of any building.
(b) 
Placement. No roof signboard shall be placed upon the roof on any building so as to prevent free passage from one part of the roof to any other part of the roof or interfere with any openings in the roof. All roof signboards shall be so constructed as to leave clear space of not less than six feet between the average roof level and the lowest part of the sign structure and at least five feet of clearance between the vertical supports except that any roof sign not exceeding five feet in height need not comply with the provisions set forth in this subsection if the specifications and plans for the erection of the sign on any roof meet with the prior approval of the commissioner of codes enforcement.
(c) 
Projection. No roof signboard shall project beyond the exterior wall of the building upon which it is erected, constructed or maintained, but, if the signboard is illuminated, the lighting reflectors may project six feet beyond the building line. When a roof signboard is erected parallel to any exterior wall, the facing of the roof signboard shall be set back at least four feet from the exterior wall.
(d) 
Materials. Every roof sign shall be constructed entirely of metal including uprights, supports and the braces of the sign, except that the ornamental molding and battens behind the metal facing and the decorative lattice work may be of wooden construction.
(e) 
Wind resistance. In the case of all roof signboards erected upon buildings which are not constructed entirely of fireproof materials, the bearing plates of the signboard shall bear directly upon the walls or upon girders which are supported on the walls and intermediate columns in the building.
(f) 
Height above roof. No roof signboard having a tight, closed or solid surface shall at any point be over 31 feet above the highest point of the roof level. Roof signboards not having a tight, closed or solid surface may be erected upon fireproof buildings to a height not exceeding 75 feet above the roof level and upon nonfireproof buildings to a height not exceeding 50 feet above the roof level, but the portions of the structure covered and exposed to wind pressure shall not exceed 40% of the total area of the sign.
(g) 
Condition. Every roof signboard and all the supports, braces, guys and anchors shall be kept and maintained in good repair and condition at all times. The commissioner of codes enforcement may order the removal of any signboards that are not maintained in a safe condition.
(h) 
Applicability. All signs under 200 square feet in size shall be deemed to be commercial signs and covered by section 2-21-48.
[Code 1964, § 3-22]
(a) 
Definition. As used in this article, "wall bulletins" means any signboard affixed to the front, rear or side wall of any building.
(b) 
Clearance. All illuminating sign reflectors must not be less than 10 feet over the sidewalk level above each wall bulletin.
(c) 
Materials; attachment. The surface face of all wall bulletins must be of sheet metal or approved fire resistant material, but the ornamental moulding and decorative lattice may be of wooden construction. Wall bulletins must be safely and adequately attached to the building wall by means of iron or metal anchors, bolts or expansion screws.
(d) 
Covering doors, windows. No wall bulletin shall be erected so as to cover a door or window of any building without the openings being first filled with fireproof material and subject to the approval of the commissioner of codes enforcement. Approval will be given if the work will comply with all laws and ordinances.

As used in this article, "commercial sign" means any letter, word, model, sign, device or representation used in the nature of any advertisement, announcement or direction that is erected, constructed, owned or maintained by any business establishment and is attached to the walls of any building and extending over the sidewalk beyond the building line.
(b) 
Classifications. A commercial sign shall be classified as one of the following:
(1) 
A projecting commercial sign which is one that is affixed to the building wall and which extends more than 12 inches over public property.
(2) 
A flat commercial sign which is one that is attached in a rigid manner lying parallel to the building wall.
(c) 
Erection and maintenance. No commercial sign extending more than 12 inches over public property shall be erected, constructed, altered or maintained until after the permit provided for in this chapter to so erect, construct, alter or maintain the sign has been secured from the commissioner of codes enforcement and until after the required fee has been duly paid.
(d) 
Illuminated signs. No commercial sign shall be illuminated otherwise than by electricity as a primary source, and illuminated commercial signs shall be constructed entirely of metal or other noncombustible material. Commercial signs shall be firmly attached to the building and so constructed as not to be or become dangerous.
(e) 
Projection and clearance. No commercial sign may extend beyond the visual curbline in front of the premises to which it is attached, and the sign shall be fixed to the building so that the overhanging part of the sign shall not be less than 10 feet above the sidewalk level. This restriction shall not apply to commercial signs attached parallel to the building wall.
[Code 1964, §§ 3-36—3-41]
(a) 
Erection and installation generally. No electrical sign or outline lighting installation shall be erected or installed within the limits of the city unless it shall bear the label of the Underwriters' Laboratories, Inc., or the approval of the New York Board of Fire Underwriters. Any alteration, change, addition, repair or removal to a location different from that which it was originally approved shall void the label and/or the approval of the New York Board of Fire Underwriters which was issued for the sign or outline lighting before the alteration, change, addition, repair or removal to a different location.
(b)

Compliance with the requirements of the current edition of the National Electrical Code, published by the National Fire Protection Association, shall be prima facie evidence of a safe installation.
(c) 
Prerequisites to installation. It shall be a violation for any person to install any electrical sign or outline lighting installation without first obtaining an electrical permit and without filing an application for inspection with the New York Board of Fire Underwriters.
(d) 
Connection to energy source. No sign or outline lighting installation shall be connected to any electrical circuit, feeder or to any source of electrical energy except by a licensed electrician and then only after a city permit has been obtained and an application for inspection by the New York Board of Fire Underwriters has been filed as required by the laws and ordinances of the city, except that an approved portable sign may be plugged into an approved receptacle outlet.
