N.D. Cent. Code § 14-02.5-07
A person whose business includes engaging in residential real estate-related transactions may not discriminate against an individual 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, sex, disability, age, familial status, national origin, or status with respect to marriage or public assistance. A residential real estate-related transaction is the selling, brokering, or appraising of residential real property or the making or purchasing of loans or the provision of other financial assistance to purchase, construct, improve, repair, maintain a dwelling, or to secure residential real estate. Nothing in this section prohibits a person engaged in the business of furnishing appraisals of real property to take into consideration factors other than race, color, religion, sex, disability, age, familial status, national origin, or status with respect to marriage.
