(8) Every window located at or near ground level, used or intended to be used for ventilation,
and every other opening located at or near ground level which might provide an entry
for rodents, must be supplied with adequate screens or other devices that will effectively
prevent their entrance.
(9) Every dwelling or accessory structure and the premises upon which they are located
shall be rodent-proofed and maintained to prevent rodents’ harborage.
(10) All openings in the exterior walls, foundations, basement, ground or first floors,
and roofs which have a half-inch (1/2") diameter or more opening shall be rat-proofed in an approved manner if they are
within forty-eight inches (48") of the existing exterior ground level immediately
below those openings, or if they may be reached by rats from the ground by climbing
unguarded pipes, wires, cornices, stairs, roofs, and other items as trees or vines
or by burrowing.
(11) Skirting, lattice, or other non-rat-proofed enclosures displaying evidence of rat
harborage under a porch or any portions of a building must be rat-proofed at all locations
where evidence of burrowing or gnawing was found.
(12) In the event that occupancy usages would result in stacking or piling materials, the
materials be arranged to prohibit the creation of a harborage area. This can be accomplished
by orderly stacking and elevating so that there is a twelve inch (12") opening between
the material and the ground level. No stacking or piling of material shall take place
against the exterior walls of the structure.
