§ 58-163. Windows.

(a)

For purposes of this division, all windows and other openings for the purpose of light or ventilation located in the side or rear of exterior walls and within 30 inches above the existing ground level immediately below such opening shall be covered for their entire height and width, including frame, with wire cloth of 19 gauge or heavier, having a mesh of not larger than one-half inch.

(b)

All windows and other openings for the purpose of light or ventilation in the exterior walls that may be accessible to rats by way of exposed pipes, wires, conduits and other appurtenances shall be covered with guards of wire cloth of 19 gauge or heavier, having a mesh of not larger than one-half inch, or in lieu of wire cloth covering the pipes, wires, conduits and other appurtenances shall be blocked from rat usage by installing sheetmetal guards of 24 gauge or heavier. Such guards when used on horizontal pipes, wires, conduits or other appurtenances shall be placed in a vertical position and shall be snugly fitted around the pipe, wire, conduit or other appurtenance. The guard shall measure not less than 12 inches beyond and on all sides of the pipe, wire, conduit or other appurtenance where the intervening space between the wall and pipe permits and shall extend 30 inches in an upward direction and 12 inches in a downward direction and shall be securely fastened to the pipe, wire, conduit or other appurtenance and also to the adjacent wall wherever practicable so that the guard will remain in a vertical position at all times.

(c)

Such guards when used on vertical pipes, wires, conduits or other appurtenances shall be fitted snugly around the pipe, wire, conduit or other appurtenance; shall be placed in a horizontal position (right angle to pipe, etc.); shall extend horizontally from the pipe, wire, conduit or other appurtenance for a minimum distance of 12 inches beyond and on all sides of the pipe, wire, conduit or other appurtenance, where the intervening space between pipe and wall permits; and shall be securely fastened to the pipe, wire, conduit or other appurtenance and also to the adjacent wall wherever practicable in such manner that the guard will remain in a horizontal position at all times.
