§ 12-145. Windows.

(a)

All windows of business buildings through which rodents may gain entrance, such as those having sills less than thirty (30) inches from the ground, or those that may be accessible to rodents from the roof of the same buildings or adjacent structures, and those that rodents may gain entrance to by climbing the walls of the building or by means of vines, trees, wires, pipes, or any other installation, are required to be rodent-proofed if the windows are liable to be left open during the night or day, unless the Health Officer is satisfied that they are already appropriately protected by screening, grills, or wire cloth.

(b)

Windows shall be rodent-proofed by covering their entire surface with nineteen (19) gauge or heavier wire cloth having a mesh not greater than one-half (1/2) inch. The wire cloth is to be securely fastened to wood frames that are to be installed so that they may be readily removed in order to clean the windows or for other purposes. The edge of the wire cloth along the entire outer margin of the frames should be covered with metal strips approximately one (1) inch wide; provided, that there is scrap metal available for this purpose.

(c)

At the discretion of the Health Officer, when appropriate situations arise a metal rodent guard of twenty six (26) gauge or heavier metal may be substituted for the wire cloth covering of windows. The metal guard shall be approximately eighteen (18) inches wide, or its upper margin thirty (30) inches or more above the surface of the ground below the window. Its upper outer margin will extend out nine (9) inches from the window frame while the lower margin will extend downward and inward to within three-eighths (3/8) inch of the outer edge of the sill. The sides should fit tightly against the outer margin of the window frame on each side. If necessary to prevent the accumulation of trash, the space between the upper margin of the guard and the window should be capped with wire cloth.
