Lawrence, KS Public Health Rules: Rodent Control (2026)

4 to fix who is legally responsible when rodents, insects, or other pests show up on a property. 3, the occupant of a detached dwelling unit, or of a single-tenant nonresidential structure, is responsible for pest elimination on the premises, but only after 30 days of occupancy, giving a new resident a month before that duty attaches. 4 covers larger properties differently: the owner of a structure containing two or more dwelling units, a multiple occupancy building, a roominghouse, or a nonresidential structure is responsible for pest elimination in the public or shared areas of the structure and all exterior areas of the premises, which reaches common hallways, shared yards, and dumpster areas that no single tenant controls.

That same owner is also on the hook for eliminating an infestation inside an individual dwelling unit if the infestation is discovered within the first 30 days of a new tenancy, on the theory that a pest problem found that quickly likely predates the tenant's move-in. After the 30-day window closes, responsibility for pest control inside a unit generally shifts back to the individual occupant. Because these sections sit inside the property maintenance code enforced citywide by the Director of Planning and Development Services as code official, a rodent complaint against a landlord or an owner-occupant is investigated the same way as any other maintenance violation.
