Arcadia Municipal Code § 5220.2 Ratproofing Requirements

No person shall maintain or use any building or structure or portion thereof for a slaughterhouse, packing house or bakery, or for the manufacture, preparation, storage, handling, or display of any food or food product for human or animal consumption or for the storage, handling, preparation or sale of any grain or grain products, which, in the opinion of the Health Officer, is or is likely to become infested with rats, unless such building or structure or portion thereof be ratproofed in accordance with the provisions of this Part.

When determined by the Health Officer that any such building or structure constitutes a rat harborage, he may serve upon the person in charge or control thereof a notice in writing to ratproof such building or structure in accordance with the requirements of this Part, within a reasonable time as stated in such notice. When determined by the Health Officer that it is unnecessary to ratproof such building or structure in its entirety, he may specify in such notice that portion thereof which is to be ratproofed.

No person shall use any building or structure, except dwellings or apartments, for the storage or handling of any grain or grain product, or of any food or food product for human or animal consumption, unless such building complies with all the provisions of this Code, and with the provisions of the following subsections.

Except as otherwise provided, all foundations of such buildings or structures shall be continuous foundations as specified for Type V Buildings in Section 2806 and Table 28-A of the Uniform Building Code.

A twelve inch (12″) strip of noncorrodible metal lath weighing not less than ¾ pounds per square yard shall be placed under wall coverings on both inside and outside of all exterior stud walls at the floor level, except that said strip need not be placed on the outside face when there is maintained a clearance of eighteen inches (18″) under the floor joists or when the exterior wall covering is stucco.

All underfloor vents, openings in foundation, roof vents and skylights shall be screened by use of screening of at least one-half (½) inch mesh hardware cloth.

No person shall permit an accumulation of rubbish material that may serve as a harborage for rats unless such material be elevated not less than eighteen (18) inches above the ground with a clear intervening space thereunder.
