Norwalk, CT Public Health Rules: Rodent Control (2026)

Section 59-4H of the Housing Code makes rodentproofing a minimum standard for every dwelling and accessory structure: the building and the ground it sits on must be maintained so rodents cannot harbor there, graded and drained, kept free of standing water, and kept clean, sanitary and safe. Section 59-8F then assigns responsibility for actual extermination. A single-family occupant is responsible for exterminating insects, rodents or other pests on the premises. In a multi-unit dwelling, an occupant is responsible only if their own unit is the sole one infested; if the infestation exists in two or more units or in shared or public areas, or if it results from the owner's failure to keep the building ratproof or insectproof, the owner must handle extermination.

Section 59-8J and 59-8K add that occupants must store garbage and organic waste in secure, watertight containers, and that no owner or occupant may accumulate rubbish, boxes, lumber or scrap metal in a way that provides rodent harborage. The Director of Public Health enforces these standards through inspections under § 59-2 and the notice-and-hearing process before the Code Enforcement Committee under § 59-3.
