S.D. Codified Laws § 20-13-21.2
It is an unfair or discriminatory practice to design or construct any multifamily dwellings with more than four units for sale, rent, lease, assignment, sublease, or transfer that do not enable accessibility to ground-floor common areas and usability of ground-floor housing units by disabled persons or by wheelchairs. If the building has elevators, all housing units and common areas shall be usable by disabled persons and persons in wheelchairs. The accommodations may include widened doors, lowered electrical switches and outlets, lowered environmental controls, grab bars or reinforcements, kitchens and bathrooms usable by the disabled. Nothing in this law may be construed to require prior approval of plans for construction by the Division of Human Rights or the Commission of Human Rights.
