It shall be unlawful to erect or maintain any cloth sign over any street or other public thoroughfare within the City, except as provided by this section.
For special advertising purposes, the chief building official may at his discretion issue a permit for the erection of temporary signs made of cloth, or of compressed fiber not more than one-quarter of an inch thick, to be attached to the face of a building, or to the face of a flat or projecting sign. Such sign shall be erected in a manner ordered and approved by the chief building official, but shall not be permitted to remain in place for a period exceeding thirty days.
The mayor shall have the right to authorize the temporary hanging of display banner or other cloth decorations for special occasions such as religious, civic or festival occurrences, or for Christmas decorations, or in celebration of some event of religious, national, state or civic significance, or in honor of a visit from a person of note. It is especially provided, however, that advertising of a commercial nature shall not be made a part of such decorations. No such temporary signs, decorations, or displays shall be displayed for more than sixty days. The permission for such displays shall be issued without charge for any fee.
Within the fire limits, all cloth signs or other signs made of flammable material shall be treated with a fire-retarding solution subject to the approval of the chief of the fire department before being erected.
