Livonia, MI Public Health Rules: Rodent Control (2026)

5 for Livonia specifically. It requires all structures and exterior property to stay free from rodent harborage and infestation, and it names one concrete example: firewood stored on site has to be stacked in an orderly fashion and kept at least one foot above the ground. If rodents turn up anyway, the owner must have them promptly exterminated using approved methods that won't injure human health, and afterward must take precautions to eliminate the harborage and prevent reinfestation. 32, enforced by the Director of Inspection acting as code official.

155: any exterior wall, shed, porch or accessory building not built on a continuous masonry or concrete foundation must have a rat and vermin proof wall, defined in the code as a continuous concrete wall at least 4 inches wide and 24 inches deep below grade, with wood-framed structures required to extend that wall an additional 4 inches above grade. The property maintenance code also carries its own penalty clause rather than relying only on the general code default.
