Kan. Stat. Ann. § 58-2560
If the landlord fails to deliver possession of the dwelling unit to the tenant as provided in K.S.A. 58-2552, rent abates until possession is delivered and the tenant:
(b) may demand performance of the rental agreement by the landlord and, if the tenant elects, maintain an action for possession of the dwelling unit against the landlord, or any person wrongfully in possession, and recover the damages sustained by such tenant.
If a person's failure to deliver possession is willful and not in good faith, an aggrieved party may recover from such person an amount not more than one and one-half (11/2) months' periodic rent or one and one-half (11/2) times the actual damages sustained by such party, whichever is greater.
