Kan. Stat. Ann. § 44-1018

(a) Nothing in this act shall prohibit a religious organization, association or society, or any nonprofit institution or organization operated, supervised or controlled by or in conjunction with a religious organization, association or society, from limiting the sale, rental or occupancy of real property which it owns or operates for other than a commercial purpose to persons of the same religion, or from giving preference to such persons, unless membership in such religion is restricted on account of race, color, national origin or ancestry. Nor shall anything in this act prohibit a nonprofit private club in fact not open to the public, which as an incident to its primary purpose or purposes provides lodgings which it owns or operates for other than a commercial purpose, from limiting the rental or occupancy of such lodgings to its members or from giving preference to its members.

(b) Nothing in this act, other than the prohibitions against discriminatory advertising as provided in subsection (c) of K.S.A. 44-1016 and amendments thereto, shall apply to:

(1) The sale or rental of any single family house by an owner, provided the following conditions are met:

(A) The owner does not own or have any interest in more than three single family houses at any one time; and

(B) the house is sold or rented without the use of a real estate broker, agent or salesperson or the facilities of any person in the business of selling or renting dwellings. If the owner selling the house does not reside in it at the time of the sale or was not the most recent resident of the house prior to such sale, the exemption in this subsection applies to only one such sale in any 24-month period; or

(2) rooms or units in buildings containing living quarters occupied or intended to be occupied by no more than four families living independently of each other, if the owner actually maintains and occupies one of such living quarters as the owner's residence.

(c) (1) Nothing in this act limits the applicability of any reasonable local, state or federal restrictions regarding the maximum number of occupants permitted to occupy a dwelling. Nor does any provision in this act regarding familial status apply with respect to dwellings provided under any state or federal program specifically designed and operated to assist elderly persons, as defined in the state or federal program, or to housing for older persons.

(2) As used in this subsection (c), "housing for older persons" means housing communities:

(A) Intended for, and at least 80% occupied by, at least one person 55 years of age or older per unit and providing significant facilities and services specifically designed to meet the physical or social needs of such persons; or

(B) intended for and occupied solely by persons 62 years of age or older.

(d) Nothing in this act prohibits conduct against a person because such person has been convicted two or more times by any court of competent jurisdiction of the illegal manufacture or distribution of a controlled substance as defined in section 102 of the federal controlled substances act (21 U.S.C. 802).
