Whenever canvas awnings and fixed canvas hoods or canopies are permitted under the ordinances of the urban county government, fixed or retractable metal awnings may be used if properly attached to buildings and if applicable requirements are met; provided:
(1) They are made of rust-resistive material.
(2) They are installed above windows or doors.
(3) They are in no case less than eight (8) feet clear above sidewalk or grade when projecting over public property.
(4) They shall not extend more than eight (8) feet from the building with a slope not to exceed an angle of forty-five (45) degrees from the horizontal, and in no case shall they extend over more than half the width of the sidewalk; provided the provisions of this subsection shall not apply to stationary canopies, or to dwellings not over two and one-half (2½) stories high.
(5) They shall not extend below the upper sixty (60) percent of any window opening.
(6) They shall not project over four (4) feet when installed above the first floor.
(7) They shall not be installed above the second floor without the written approval of the chief of the fire and emergency services division; provided such approval by the chief of the fire and emergency services division shall not be required for installation on dwellings not over two and one-half (2½) stories high and not occupied above the second floor.
(8) A permanent awning shall not be permitted on the first floor of buildings over one (1) story high where there are window openings in the wall above and directly over the first floor awning, unless such awning is designed and constructed in the manner which will permit it to be readily collapsed against the building; provided, the provisions of this subsection shall not apply to dwellings not over two and one-half (2½) stories high and not occupied above the second floor.
(9) They shall not bear any indicia, either painted or attached, nor shall they be wired for electric illumination or have any extraneous attachments of any kind except that the name, street number and character of business of the owner may be printed or painted thereon.
(10) Before any permanent awning shall be erected on a building, other than a dwelling, not more than two and one-half (2½) stories high and not occupied above the second floor, a building permit shall be obtained from the director of inspection of the urban county. Applications for such permits shall be made by the licensed awning contractors and the same procedure shall be followed as prescribed for the erection of signs in the building code, adopted and incorporated herein by reference in section 5-1.
