   P.   For purposes of handicap discrimination in housing pursuant to this article, the term "discrimination" includes:
      1.   A refusal to permit, at the expense of the handicapped person, reasonable modifications of existing premises occupied or to be occupied by the person if the modifications may be necessary to afford the person full enjoyment of the premises, provided that such person also provides a surety bond guaranteeing restoration of the premises to their prior condition, if necessary to make the premises suitable for non- handicapped tenants;
      2.   A refusal to make reasonable accommodations in rules, policies, practices, or services when the accommodations may be necessary to afford the person equal opportunity to use and enjoy a dwelling; or

         a.   The public use and common use portions of the dwellings are readily accessible to and usable by a handicapped person;
         b.   All the doors designed to allow passage into and within all premises within the dwellings are sufficiently wide enough to allow passage by handicapped persons in wheelchairs; and
         c.   All premises within the dwellings contain the following features of adaptive design:
            (1)   An accessible route into and through the dwelling;

         f.   Nothing in this subsection requires that a dwelling be made available to an individual whose tenancy would constitute a direct threat to the health or safety of other individuals or whose tenancy would result in substantial physical damage to the property of others;
   Q.   1.   A person whose business includes engaging in residential real estate- related transactions may not discriminate against a person in making a real estate-related transaction available or in the terms or conditions of a real estate-related transaction because of race, color, religion, gender, handicap, familial status, national origin, or age;
      2.   In this section, "residential real estate-related transaction" means:
         a.   Making or purchasing loans or providing other financial assistance:
            (1)   To purchase, construct, improve, repair, or maintain a dwelling; or
            (2)   To secure residential real estate; or
