(Amended by Ordinance No. 176955, effective October 9, 2002.)
A. “Approved” as used in this Chapter where it applies to articles, materials, and methods means such articles as are approved by the Health Officer, who must approve each article, material, or method used in the exclusion of rodents.
B. “Impervious material” includes glass, wood, noncorrosive steel or iron and noncorrosive metal screen. The mesh of such screen shall not be larger than 1/4 inch and the thickness of the wire not less than No. 20, Brown and Sharpe gauge. Concrete masonry or other material which upon investigation by the Bureau of Development Services of this City shall be found to be of such hardness and texture as to effectively prevent penetration by rats. If any such material be found by the Health Officer to be insufficient to exclude rats by reason of decay, rot, breakage or other local or special condition, it shall no longer be termed impervious.
