Jefferson Parish, LA Public Health Rules: Rodent Control (2026)

The rule sits in Sec. 10, Rodent harborage, part of Division 7's Property Maintenance Code inside Chapter 8's building regulations. It applies to all structures and exterior property, not just occupied dwellings, so vacant buildings and undeveloped lots carry the same duty to stay free of rodent harborage and infestation as an occupied home. Once rodents are found, the code requires them to be promptly exterminated, and only through approved processes that will not be injurious to human health, which rules out do-it-yourself methods involving hazardous chemicals.

The obligation does not end at extermination. The code requires proper precautions afterward specifically to eliminate the harborage conditions and prevent re-infestation, meaning sealing entry points, removing food sources, or clearing the debris and clutter that let rodents nest in the first place. That duty connects directly to the neighboring maintenance-responsibility section, Sec. 8, which makes every occupant responsible for disposing of rubbish, garbage, and other organic waste in a clean and sanitary manner and for keeping available the containers needed to store it, since uncontrolled garbage is a common cause of the rodent harborage the parish is targeting.

Structures that become a public nuisance because of conditions like unchecked rodent infestation can also be pulled into Sec. 11's broader nuisance and dangerous-buildings process, which applies its own penalties on top of the maintenance code's baseline enforcement.
