(g) Projecting signs shall not extend into the public way a greater distance than within 18 inches (457 mm) of the curb line.

(i) No sign shall be attached to or supported by a chimney unless special permission has been obtained in writing from the Building Commissioner before the permit is issued.
If a street is widened after a sign has been installed and such sign thereby becomes in violation of one of the provisions of this section, the owner or user of said sign shall immediately take such steps as are necessary to bring the sign into conformance with all applicable provisions of this chapter.
