The City's rodent-proofing rule for new buildings
Section 5-2 of the City code lists Appendix F, Rodent Proofing, among the International Building Code appendices Ranson has adopted, in a block with several other appendices. The International Code Council says the appendix is not mandatory unless the adopting ordinance names it, and West Virginia's State Building Code rule, 87CSR4 section 7.3, says appendices must be adopted locally to be enforceable.
- Which buildings it reaches: New buildings under the International Building Code, such as apartment and commercial buildings. Detached one- and two-family homes, and townhouses up to three stories that each have their own way out, can use the International Residential Code instead.
- Houses under the residential code: The residential-code appendices listed in Section 5-2 include no rodent-proofing appendix, so this one does not reach a house built to the International Residential Code.
- Foundation vent openings: Vent openings in foundation walls are covered with sheet metal, grating or hardware cloth, with openings no larger than 1/4 inch.
- Gaps around pipes and cables: The space around pipes, cables and conduits that pass through walls is closed with cement mortar, concrete masonry or noncorrosive metal, under section F101.3 of the appendix.
- Buildings already standing: Appendix F, like the 1/4-inch vent rule above, sets how new construction is built. It is not an upkeep rule for buildings already standing.
