The temporary occupancy of a sidewalk or street or other public
property during construction, removal, repair, alteration, or maintenance
of a sign is permitted, provided the space occupied is roped off,
fenced off, or otherwise isolated to prevent hazard to pedestrians
and property.
Supporting members or braces of all signs shall be constructed
of galvanized iron, properly treated wood, steel, or other noncorrosive
incombustible material. All projecting signs, if placed at an angle
to the wall or roof of any building, shall be attached by such noncorrosive
metal bolts, anchors, cable, or other metal attachments as shall ensure
permanent and safe construction and shall be maintained free from
rust or other defects. Every means or device used for attaching any
sign shall extend through the walls or roof of the building, should
the Building Inspector determine that the safe and permanent support
of such sign so requires, and shall be securely anchored by wall plates
and nuts to the inside of the walls or to bearings on the underside
of two or more roof or ceiling joists in accordance with instructions
given by the Building Inspector. Small flat signs containing less
than 10 feet of area may be attached to a building by the use of lag
bolts or other means to the satisfaction of the Building Inspector.
No sign, or any part thereof, or sign anchors, braces, or guide
rods shall be attached, fastened, or anchored to any fire escape,
fire ladder, or standpipe, and no such sign or any part of any such
sign or any anchor, brace, or guide rod shall be erected, put up or
maintained so as to hinder or prevent ingress or egress through a
door, doorway, or window or so as to hinder or prevent the raising
or placing of ladders against a building by the Fire Department as
necessity therefor may require.
