State Laws and Rights
Kansas mold law snapshot
Kansas does not have a mold-specific statute, but habitability rules still apply.
Under K.S.A. 58-2553, Kansas landlords must comply with applicable building and housing codes materially affecting health and safety, maintain common areas in a safe condition, keep all electrical, plumbing, sanitary, heating, ventilating, and air-conditioning systems in good and safe working order, provide adequate waste removal facilities, and supply running water, reasonable amounts of hot water, and reasonable heat. The implied warranty of habitability, established in Steele v. Latimer (1974) and codified in K.S.A. 58-2553, requires landlords to provide housing that is fundamentally decent, safe, and sound.
