Chandler, AZ Public Health Rules: Rodent Control (2026)

Chapter 30's miscellaneous nuisance article, § 30-20(L), is Chandler's core vector-control rule. It bars any person from causing, allowing, leaving or permitting a vector, vermin, or other noxious pest infestation of any kind to remain in or upon a private lot, building, structure or property, and the list of covered pests explicitly includes rats and rodents alongside insects, bees, wasps and pigeons. The second sentence goes further than a bare infestation ban: all premises must be kept free from the presence or apparent evidence of infestation, including nesting places, or any other unsightly or unsanitary condition that could harbor infestations, meaning an inspector doesn't need to spot live rodents to cite a property, visible nesting material or harborage conditions are enough.

This sits alongside related Chapter 30 property-maintenance duties, including § 30-18(G)'s ban on uncontrolled, unmaintained grass and weeds that 'may harbor infestations,' and § 30-18(K)'s rule against palm trees with dead-frond accumulations that can breed insects or other infestations. Together the sections give Neighborhood Resources inspectors overlapping tools: they can cite overgrown vegetation, dead palm fronds, or the rodent harborage itself, whichever condition is present on a given property.
